git clone --depth 1 https://github.com/mtotschnig/MyExpenses.git
cd MyExpenses
export ANDROID_HOME={sdk-dir}
./gradlew build

If gradlew gives you a "Failed to install the following Android SDK packages" error message, the packages can be installed manually with commands such as:

$ANDROID_HOME/cmdline-tools/bin/sdkmanager --install --sdk_root=$ANDROID_HOME "platforms;android-32"
$ANDROID_HOME/cmdline-tools/bin/sdkmanager --install --sdk_root=$ANDROID_HOME "build-tools;30.0.3"

If gradlew errors out with "Could not dispatch a message to the daemon", just re-run the command. This can happen when the system is low on memory. The same is true for the "Gradle build daemon disappeared unexpectedly" error.

My Expenses now has experimental support for inserting data from third party apps. See TransactionsContract.java.
