+## How to build development builds of the router core for android?
+
+Check the RELEASE-PROCESS.md file for general information about how to build and to bump the version.
+
+In your i2p.i2p codebase checkout, execute `./installer/resources/maven-dev-release.sh` with your build number as first argument.
+The script locates itself and uses the same codebase as it's in, to produce the maven builds which will be locally installed.
+
+Next, add the build number to the gradle.properties and build the android build as usual.

+Docker Build Instructions
+=========================
+
+It is possible to build a container with a pre-installed environment for
+correctly compiling an I2P for Android development build. Unlike the i2p.i2p
+container, zero attempt has been made to optimize the size of the container,
+as it contains a copy of the latest Android SDK, toolchains, and Android NDK,
+which it must download. To save time, this is cached locally. It is likely to
+take up to 30 GB of disk space to compile in this way, however, it is very easy
+and convenient compared to the steps in RELEASE-PROCESS.md and may make
+building Android reproducibly easier in the future.
+
+Container dependencies
+----------------------
+
+  - `menny/android_ndk` (third-party image) (reviewed by idk) (depends on menny/android_sdk
+  - `menny/android_sdk` (third-party image) (reviewed by idk) (depends on ubuntu/18.04)
+  - `ubuntu/18.04` (official docker container) (base container)
+
+Build the container locally
+---------------------------
+
+Run:
+
+        docker build -t i2p.android.base .
+
+To build the container. It will have a lot to download the first time, so it may take
+a while to complete.
+
+Run an Android build in the container
+-------------------------------------
+
+Copy the `etc/docker.signing.example.proprties` file to `etc/docker.signing.proprties`,
+edit it to match your key information and rebuild the container.
+
+Run:
+
+        docker run -it \
+          -u $(id -u):$(id -g) \
+          --name i2p.android.base \
+          -v $HOME/.gnupg/:/.gnupg/:ro \
+          -v $HOME/.i2p-plugin-keys/:/.i2p-plugin-keys/:ro \
+          -v /run/user/$(id -u)/:/run/user/$(id -u)/:ro \
+          i2p.android.base
+
+To get the build artifacts for uploading to Maven out of the container, use:
+
+        docker cp i2p.android.base:/opt/workspace/i2p.i2p/pkg-mavencentral app/pkg-mavencentral
+        docker cp i2p.android.base:/opt/workspace/i2p.i2p/mavencentral-i2p.jar app/pkg-mavencentral
+        docker cp i2p.android.base:/opt/workspace/i2p.i2p/mavencentral-mstreaming.jar app/pkg-mavencentral
+        docker cp i2p.android.base:/opt/workspace/i2p.i2p/mavencentral-router.jar app/pkg-mavencentral
+        docker cp i2p.android.base:/opt/workspace/i2p.i2p/mavencentral-servlet-i2p.jar app/pkg-mavencentral
+        docker cp i2p.android.base:/opt/workspace/i2p.i2p/mavencentral-streaming.jar app/pkg-mavencentral
+
+To get the Android build artifacts out of the container, use:
+
+        docker cp i2p.android.base:/opt/workspace/i2p.android.base/app/build/ app/build
+
+And your android applications will appear in the `app/build` directory, in the same
+place where non-container builds would go.
+
+If you encounter a permissions error when rebuilding, delete the `app/build`,
+`app/pkg-mavencentral` and `app/pkg-temp` path.
+
+        rm -rf app/pkg-temp app/build app/pkg-mavencentral
+
+Copypasta
+---------
+
+Once you have set up builds for the first time, from then on you can update the container and
+build a fresh set of Maven jars and a new I2P for Android app by copy-pasting the following
+commands:
+
+``` sh
+rm -rf app/pkg-temp app/build app/pkg-mavencentral
+docker build -t i2p.android.base .
+docker run -it \
+  -u $(id -u):$(id -g) \
+  --name i2p.android.base \
+  -v $HOME/.gnupg/:/.gnupg/:ro \
+  -v $HOME/.i2p-plugin-keys/:/.i2p-plugin-keys/:ro \
+  -v /run/user/$(id -u)/:/run/user/$(id -u)/:ro \
+  i2p.android.base
+docker cp i2p.android.base:/opt/workspace/i2p.i2p/pkg-mavencentral app/pkg-mavencentral
+docker cp i2p.android.base:/opt/workspace/i2p.i2p/mavencentral-i2p.jar app/pkg-mavencentral
+docker cp i2p.android.base:/opt/workspace/i2p.i2p/mavencentral-mstreaming.jar app/pkg-mavencentral
+docker cp i2p.android.base:/opt/workspace/i2p.i2p/mavencentral-router.jar app/pkg-mavencentral
+docker cp i2p.android.base:/opt/workspace/i2p.i2p/mavencentral-servlet-i2p.jar app/pkg-mavencentral
+docker cp i2p.android.base:/opt/workspace/i2p.i2p/mavencentral-streaming.jar app/pkg-mavencentral

-1) java -jar i2pinstall.exe -console       (you've already done this)
-
-This will run the installer in text mode, including running the postinstall.sh
-script. After that, you may run 'sh i2prouter start'
-which will start the router and attempt to launch a browser.
-
-If you do not have an X server running, the browser launch will probably fail, and
-you may use:
-  lynx http://localhost:7657/index.jsp
-to configure the router.
-
-If you're having trouble, swing by http://forum.i2p2.de/, check the
-website at http://www.i2p2.de/, or get on irc://irc.freenode.net/#i2p
-
-I2P will create and store files and configuration data in the user directory
-~/.i2p/ on Linux and %APPDATA%\I2P\ on Windows. This directory is created
-when I2P is run for the first time. It also creates files in the system
-temporary directory specified by the Java Virtual Machine.
-To change the location of these directories, or to configure I2P to
-put all files in this directory (the so-called "portable" configuration),
-edit the files i2prouter (Linux) and wrapper.config (Linux and Windows)
-where there are comments labeled "PORTABLE". Do this before you
-run I2P for the first time.
-
-To run I2P explicitly:
-   (*nix): sh i2prouter start
-   (win*): I2P.exe
-
-To stop the router (gracefully):
-   lynx http://localhost:7657/configservice.jsp ("Shutdown gracefully")
-
-To stop the router (immediately):
-   sh i2prouter stop
-
-To uninstall I2P:
-   rm -rf $i2pInstallDir

-Prerequisites to build from source:
-	Java SDK (preferably Sun) 1.5.0 or higher (1.6 recommended)
-	Apache Ant 1.7.0 or higher
-	Optional, For multilanguage support: The xgettext, msgfmt, and msgmerge tools installed
-	from the GNU gettext package http://www.gnu.org/software/gettext/
-
-To build and install I2P from source, you must first build
-and package up the appropriate installer by running:
-
-  ant pkg
-
-
-This will produce a few key files:
-* install.jar:    the GUI and console installer
-* i2pinstall.exe: the GUI and console installer wrapped for cross-platform execution
-* i2pupdate.zip:  the update package
-
-From there, you can run the headless (console mode) installer:
-  java -jar i2pinstall.exe -console
-
-Or run the GUI installer:
-  java -jar i2pinstall.exe
-
-Or move the update file into an existing installation directory and restart.

+# I2P Android
+
+## Build process
+
+### Dependencies:
+
+- Java SDK (preferably Oracle/Sun or OpenJDK) 1.6.0 or higher
+- Apache Ant 1.8.0 or higher
+- I2P source
+- Android SDK for API 28 or higher
+- Android Build Tools 28.0.0 or higher
+- Android Support Repository
+- Gradle 2.2.1
+
+### Gradle
+
+The build system is based on Gradle. There are several methods for setting Gradle up:
+
+* It can be downloaded from [the Gradle website](http://www.gradle.org/downloads).
+
+* Most distributions will have Gradle packages. Be careful to check the
+  provided version; Debian and Ubuntu have old versions in their main
+  repositories. There is a [PPA](https://launchpad.net/~cwchien/+archive/gradle)
+  for Ubuntu with the latest version of Gradle.
+
+* A Gradle wrapper is provided in the codebase. It takes all the same commands
+  as the regular `gradle` command. The first time that any command is run, it
+  will automatically download, cache and use the correct version of Gradle.
+  This is the simplest way to get started with the codebase. To use it, replace
+  `gradle` with `./gradlew` (or `./gradlew.bat` on Windows) in the commands
+  below.
+
+Gradle will pull dependencies over the clearnet by default. To send all Gradle
+connections from your user over Tor, create a `gradle.properties` file in
+`~/.gradle/` containing:
+
+```
+systemProp.socksProxyHost=localhost
+systemProp.socksProxyPort=9150
+```
+
+### Preparation
+
+1. Download the Android SDK. The simplest method is to download [Android Studio](https://developer.android.com/sdk/installing/studio.html).
+
+  * If you are using an existing Android SDK, install the Android Support
+    Repository via the SDK Manager.
+
+2. Check out the [`i2p.i2p`](https://github.com/i2p/i2p.i2p) repository.
+
+3. Create a `local.properties` file in `i2p.android.base/lib/client` containing:
+
+    ```
+    ndk.dir=/path/to/ndk
+    ```
+
+3. Create a `local.properties` file in `i2p.android.base/routerjars` containing:
+
+    ```
+    i2psrc=/path/to/i2p.i2p
+    ```
+
+### Building from the command line
+
+1. Create a `local.properties` file in `i2p.android.base` containing:
+
+    ```
+    sdk.dir=/path/to/android-studio/sdk
+    ```
+1a. For building with a local router development build:
+    cd ../i2p.i2p
+    installer/resources/maven-dev-release.sh x // x is the build number, e.g. 6
+    cd back here
+    edit gradle.properties, add the build number x to I2P_PROPERTIES=0.9.xx-x
+
+2. `gradle assembleDebug`
+
+3. The APK files will be placed in `i2p.android.base/app/build/outputs/apk` subdirectories.
+
+4. Install debug build on phone in USB debugging mode
+    adb install app/build/outputs/apk/free/debug/app-free-debug.apk 
+
+### Building with Android Studio
+
+1. Import `i2p.android.base` into Android Studio. (This creates the `local.properties` file automatically).
+
+2. Build and run the app (`Shift+F10`).
+
+### Signing release builds
+
+1. Create a `signing.properties` file in `i2p.android.base` containing:
+
+    ```
+    STORE_FILE=/path/to/android.keystore
+    STORE_PASSWORD=store.password
+    KEY_ALIAS=key.alias
+    KEY_PASSWORD=key.password
+    ```
+
+2. `gradle assembleRelease`
+
+## Client library
+
+### "Uploading" to the local Maven repository (to use a local build of the library in a project)
+
+1. `gradle :client:installArchives`
+
+2. Add the local Maven repository to your project. For Gradle projects, add the following above any existing repositories (so it is checked first):
+
+    ```
+    repositories {
+        mavenLocal()
+    }
+    ```
+
+### Uploading to Maven Central via Sonatype OSSRH
+
+1. Add the following lines to your `~/.gradle/gradle.properties` (filling in the blanks):
+
+    ```
+    signing.keyId=
+    signing.password=
+    signing.secretKeyRingFile=/path/to/secring.gpg
+    NEXUS_USERNAME=
+    NEXUS_PASSWORD=
+    ```
+
+2. `gradle :client:uploadArchives`
+
+### Commands from the old build instructions that might be useful
+
+```
+# Create the android 4.4 (API 19) virtual device
+# (don't make a custom hardware profile)
+../android-sdk-linux/tools/android create avd --name i2p --target android-19
+
+# then run the emulator:
+#  This may take a LONG time the first time (half an hour or more)...
+#  Run the debugger to ensure it is making progress
+#   -no-boot-anim for faster boot
+#   -dns-server 8.8.8.8 if the router can't reseed
+#     ../android-sdk-linux/tools/emulator -avd i2p -no-boot-anim -dns-server 8.8.8.8 &
+../android-sdk-linux/tools/emulator -avd i2p &
+
+# or to talk to a real device in debug mode:
+# You have to do this if you get a permission error -
+# Stop ddms, unplug the device, do the following,
+# then plug in the device, then start ddms
+adb kill-server
+sudo adb start-server
+adb devices
+
+# Anyway, with I2P installed, click on the I2P icon on your device and enjoy!
+
+#other helpful commands
+../android-sdk-linux/platform-tools/adb shell
+../android-sdk-linux/platform-tools/adb pull /some/file/on/emulator some-local-dir/
+
+# copy the Dev Tools app from the emulator to your device
+adb -e pull /system/app/Development.apk ./Development.apk
+adb -d install Development.apk
+
+# reinstall an existing apk onto the emulator
+adb -e install -r bin/I2PAndroid-debug.apk

+# Release Process
+
+Note to all future maintainers: We have 4 channels that need to be updated in order to have a successful
+Android release. Many of these channels are updated at different rates, and at times you must wait on a
+third-party service to complete it's tasks before you may continue. When completing an Android release,
+keep in mind that you must update 1) Maven 2) Google Play 3) f-droid.i2p.io and 4) F-Droid main
+repository.
+
+At the time of this revision, 2020/09/13, the main Android maintainer is idk. idk updates Maven, Google
+Play, and f-droid.i2p.io, and nextl00p handles working with the F-Droid project to provide an I2P release
+in their main repository.
+
+NOTE: The docker container built by the Dockerfile in this repostory ensures that the Pre-requisites and
+Dependencies are properly met by obtaining them from the Debian package in `oldoldstable` and pre-configuring
+the override.properties that is used in the Docker container.
+
+## Tag Freezes and Translations
+
+1-2 weeks before the software is released, I2P Desktop will have a "Tag Freeze" which is the deadline for
+translations to be checked in. **When** that time comes, someone who has Transifex privileges should use
+the command: `tx push -s -R I2P.android` to push any and all changed string resources to transifex for
+translation.
+
+**>> Beginning of Docker-enabled Steps <<**
+
+## Prerequirements
+
+ 0. Update the changelog!
+ 1. Ensure you have the deprecated maven ant tasks. ( https://maven.apache.org/ant-tasks/download.cgi )
+ 2. It should exist at `~/.ant/lib/maven-ant-tasks-2.1.3.jar`
+ 3. Ensure you have hamcrest-integration, hamcrest-library, hamcrest-core in the hamcrest.home directory.
+ 4. Ensure junit 4.12 at least in junit.home, ensure the jar file is named `junit4.jar`.
+ 5. Ensure you have the Mockito framework and accompanying documentation in your $JAVA_HOME
+ 6. Ensure to have updated the changelog with the changes done.
+ 7. Ensure that you are configured to build i2p.i2p with Java 8. On Debian it is easiest to set with
+   `update-java-alternatives --set java-1.8.0-openjdk-amd64` and picking Java 8. **TODO:** add instructions for non-Debian-based
+   systems.
+ 8. Ensure that you have a Java 1.7 bootclasspath available. (See **Maven Central** step 2A.)
+
+## Get all the dependencies ready
+
+### Maven Central
+
+ 1. Check out a clean copy of i2p.i2p at the correct release version. (Make a clean checkout)
+ 2. Build the maven packages via `ant mavenCentral` where you end up with mavencentral-*.jar files in the 
+  current directory.
+ 2. **A)** I2P for Android requires a Java 1.7 bootclasspath, but the servlet jar requires Java 8. So, to do the builds:
+  - First set `javac.compilerargs=-bootclasspath /path/to/java/7/rt.jar:/path/to/java/7/jce.jar` in override.properties
+  - Build with `ant mavenCentral`
+
+**>> End of Docker-enabled Steps for Maven <<**
+
+ 3. Login to http://oss.sonatype.org for uploading the mavencentral-*.jar bundles.
+ 4. In nexus, choose "Staging Upload" and upload all of the files with upload mode set to "Artifacts with POM". 
+  When uploading the files to nexus, you *must* upload the pom.xml files, and all of their artifacts. For each 
+  component, you will need to upload a *.jar, a *.jar.asc, a *sources.jar, a *sources.jar.asc, a javadoc.jar, 
+  and a javadoc.jar.asc, and a pom.xml and a pom.xml.asc from the pkg-mavencentral directory during the "Upload
+  Artifacts with POM" operation. You will need to do this once for each component you upload to Nexus.
+ 5. Under "Staging Repositories" ensure all where uploaded correctly, select them all and press "Release"
+  in the toolbar.
+
+#### Example override.properties:
+
+        javac.version=1.7
+        javac.target=1.7
+        javac.source=1.8
+        javac.compilerargs=-bootclasspath /home/user/StudioProjects/java7bootclasspath/rt.jar:/home/user/StudioProjects/java7bootclasspath/jce.jar
+        javac.compilerargs7=-bootclasspath /home/user/StudioProjects/java7bootclasspath/rt.jar:/home/user/StudioProjects/java7bootclasspath/jce.jar
+        build.built-by=name
+
+### Android Common Build
+
+Using Docker: in order to use Docker to generate a new Android apk for release, you will
+need to run the build twice, once for the mavenCentral jars, and once for the actual Android
+app. After doing the Maven release, follow these steps in the i2p.android.base repository, and re-run
+the `docker run` step described in `DOCKER.md`
+
+ 1. Edit `routerjars/local.properties` to use the clean i2p.i2p copy.
+ 2. Pull the latest translations with `tx pull --use-git-timestamps` and commit them. (If you don't have the `tx` command,
+  do `pip install transifex-client` ). If there are broken translations, exclude them and only them.
+  - If there are any new translations, `mtn add` them, and add them to `app/src/main/res/values/arrays.xml`
+  (two places, alphabetical order please)
+ 3. Ensure that `signing.properties` contains the details of the release key. If you are using Docker, see
+  `DOCKER.md` to perform this step for Docker builds by editing `etc/docker.signing.properties` instead.
+ 4. Edit `gradle.properties` to bump the I2P version.
+ 5. Edit `app/build.gradle` to bump the Android version number.
+ 6. Edit `CHANGELOG` to add the release and date.
+ 7. If the helper has changed since the last release, edit
+    `lib/helper/gradle.properties` to bump the version.
+ 8. `./gradlew clean assembleRelease`
+
+### Libraries
+
+ 1. `./gradlew :lib:client:uploadArchives`
+ 2. If the helper version was changed and should be released: `./gradlew :lib:helper:uploadArchives`
+ 3. Check on Sonatype that everything worked, and close/release.
+
+## Release Packages
+
+### F-Droid Guide
+
+This guide is for f-droid.i2p.io, not for F-Droid's main repository. The repository keystore **and** the
+config.py used to generate the repository are required to complete this process successfully.
+
+ 1. Ensure you have the release keys, the keyfile must be placed at `~/.local/share/fdroidserver/keystore.jks`
+ 2. If it's the first time, or you have reinstalled anything, ensure `path/to/fdroid/config.py` has correct
+  information.
+ 3. Assuming you already have ran `./gradlew clean assembleRelease` from a earlier step, continue.
+ 4. `cp app/build/outputs/apk/free/release/app-free-release.apk path/to/fdroid/repo/I2P-VERSION.apk`
+ 5. Update `path/to/fdroid/metadata/net.i2p.android.txt` (The versions at the bottom of the file)
+ 6. Run `fdroid update` from inside the fdroid path (install fdroid command via `pip install fdroidserver`)
+ 7. Zip/tar the local fdroid repo and archive. `rm fdroid.tgz && tar czf fdroid.tgz archive/ repo/` from the
+  fdroid directory.
+ 8. Push to download server and put in place. (via SSH for example, `scp fdroid.tgz download.i2p2.de:~/`)
+ 9. On the server run `bin-fd/update-fdroid` and `sudo bin-fd/update-app i2p 0.9.40` (This ensures we use the
+  exact same apk file for the download page as in fdroid and gplay)
+ 10. Check F-Droid repo works, and app works.
+
+### Google Play and finishing up
+
+ 1. Verify which files that are changed via `mtn ls cha`. It shouldn't be much more than those bellow this
+  line and possible translations (`mtn ls unk`).
+ 2. Commit your release changes, `mtn ci gradle.properties lib/helper/gradle.properties app/build.gradle`
+ 3. Push free and donate builds to Google Play via https://play.google.com/apps/publish/
+ 4. Tag the new release. Example `mtn tag h: android-0.9.36`
+ 5. Push the monotone changes. Make sure that they are there at the next git sync.
+ 6. Update download page (version and hash, including F-Droid)
+

-
-Optional:
-
-chmod +x /etc/rc.d/rc.i2p only if you want it to start on boot and stop on

-
-How to start I2P:
-
-Start I2P service with-

-
-Now tell your browser to user this proxy: localhost on port 4444 and open

-
-Please see the faqs on http://www.i2p2.i2p/ or http://www.i2p2.de/ on how

+- Material design:
+  - Style for addressbook headers
+  - Change console FAM icon when possible

+  - Use Material design for LongPressButton
+  - Highlight selected tunnel in two-pane mode
+
+# Short-term
+
+- Remove peers page (HTML version)

+- Improve graphs
+  - Show fixed x range, not only available data
+  - Think about pan/zoom
+  - How to persist data across restarts?
+- Enable apps to specify when they don't need the router anymore
+
+# Silent Store approval checks to confirm/implement
+
+- Known Vulnerabilities
+  - Apps will be tested to ensure that they are not susceptible to known
+    publicly disclosed vulnerabilities. For example:
+    - Heartbleed
+    - Poodle
+    - MasterKey
+    - Common Path Traversal attacks
+    - Common SQL Injection attacks
+- Network Security Protocols
+  - All Apps that require transmission of data from the App to a system that
+    does not exist on the device must use, at a minimum, TLS1.1 standards.
+    However, Blackphone would prefer the usage of TLS1.2.
+  - Apps must not use algorithms for cryptographic purposes that are considered
+    obsolete or outdated i.e. MD5, SHA1, RC4, DES, or any encryption algorithm
+    that is weaker than AES128.
+- Transport Layer Protection
+  - All network communication should be encrypted
+  - Not vulnerable to SSl Strip
+- Data Leakage
+  - No storage of sensitive data outside of application sandbox
+  - Files should not be created with MODE_WORLD_READABLE or MODE_WORLD_WRITABLE
+  - Copy & Paste will be evaluated on a case by case basis
+  - App logs should not contain sensitive information
+- Authentication and Authorization
+  - Validate that authentication credentials are not stored on the device
+  - Must use an approved password-based key derivation function ie. PBKDF2, scrypt
+- Data-at-rest Encryption
+  - Must use at a minimum AES128 with modes CCM or GCM
+  - Should not store the encryption key on the file system
+- Permission Checks
+  - The App must function with all permissions disabled
+  - Apps must not hard crash if a permission is disabled
+  - Apps should ask users to enable permissions that are disabled if needed to
+    function properly and explain why the permission is necessary
+- Privacy Policy
+  - Apps must have a privacy policy that details how customer data is used,
+    stored, shared, etc...
+  - Apps must be configured with the customer opted out by default
+  - App logs should not contain PII
+- Error Handling
+  - Apps should follow best-practices for error handling and logging
+
+# Long-term
+
+- Reproducible builds
+- Extract RouterService into a library
+- Remote router support
+  - Implement a "router wrapper" that can represent a local or remote router
+  - Implement/use client APIs to talk to remote router
+    - I2CP
+    - I2PControl
