How to build

Cross-compile the native libraries:

This step requires the environment variables ANDROID_NDK and JAVA_HOME to be set correctly

cd app && ./prepare_fdroid.sh

Build the Android app

./gradlew build

This will build both MAINNET and TESTNET builds

For TESTNET only run ./gradlew assembleBtctestnetDebug

Rebuild the checkpoints (optional)

Start on localhost Bitcoin Core on both MainNet and TestNet and make sure they are synchronized and finished booting (verifying blocks, etc)

MainNet:

./gradlew --project-dir=bitcoinj/tools buildMainnetCheckpoints && mv bitcoinj/tools/checkpoints app/src/production/assets/checkpoints

TestNet:

./gradlew --project-dir=bitcoinj/tools buildTestnetCheckpoints && mv bitcoinj/tools/checkpoints-testnet app/src/btctestnet/assets/checkpoints

or for both in one go run:

./buildCheckpoints.sh
