+## 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

+# 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)
+

     <zzz> spewing UPnP out into cell networks is a waste of time at best and a security risk at worst, but you really want it for wifi
+- Rewrite settings config handling
+- Rewrite InitActivities
 - I2PTunnel
   - Improve tunnel list status indicators
+  - Icon overlay to indicate which tunnels are shared
+    - Or reorder / group tunnels?
   - Show all messages somewhere
+    - Bottom toolbar?
   - Icons/header images for tunnel types on details page
+  - Setting to close when not on WiFi
 - Progress feedback for addressbook subscriptions reload
 - Display release notes directly on new router version
 - Fill out help pages
+- Fix navigation to specific settings pages
 - Rewrite release notes to be release-specific
 - Fix release notes UI, either make back button use clear or add buttons
+- Notify user when autostart fails?
 - NetDB tablet view fixes
   - Refresh detail fragment when changing tab
   - Move list to correct item when changing tab
   - Create nav history when viewing RI from LS
+- Handle NetDB null cases (failed lookup of requested hash in detail page)
 - Include GeoIP db for country info
 - Maybe change router-off mechanic for various pages? Enable as they become available?
 
 # Medium-term
 
+- SQLite naming service backend to store addresses more effectively
+  - Leverage for name completion in e.g. browsers
+- Create/edit tunnels while router is not running
+- Separate out shared tunnel config
+  - Convey to users that one config controls all shared tunnels
 - Network profiles
   - User selects profile in settings
   - Change network participation etc. based on profile
   - Also look at connection type: Connectivity.isConnectionFast()
 - Expose log level overrides
+- Bug report feature
+- Replace peers page (native version)
 - Improve graphs
-  - Show time on bottom axis
   - 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
