These instructions are for the 1.5 SDK.
The build file is not compatible with the 1.1 SDK any more.
#Unzip the android SDK in ../../
#So then the android tools will be in ../../android-sdk-linux_x86-1.5_r2/tools/
#then build the android apk file:
ant debug
# Create the android 1.5 virtual device
# (don't make a custom hardware profile)
../../android-sdk-linux_x86-1.5_r2/tools/android create avd --name i2p --target 2
#then run the emulator:
../../android-sdk-linux_x86-1.5_r2/tools/emulator -avd i2p &
#then wait a couple minutes until the emulator is up
#then install the I2P app
ant install
#then run the debugger
../../android-sdk-linux_x86-1.5_r2/tools/ddms &
#to rebuild and reinstall to emulator:
ant reinstall
