Question

Using Android Studio how do I get a signed, non-debug and zip aligned APK?

So far I can get a signed one but it gets rejected because it has debugging in it.

It is possible to take any existing Android Studio gradle project and build/sign it from the command line without editing any files. This makes it very nice for storing your project in version control while keeping your keys and passwords separate and not in your build.gradle file:

./gradlew assembleRelease -Pandroid.injected.signing.store.file=$KEYFILE -Pandroid.injected.signing.store.password=$STORE_PASSWORD -Pandroid.injected.signing.key.alias=$KEY_ALIAS -Pandroid.injected.signing.key.password=$KEY_PASSWORD
