To build an Android app:
Download and Install JDK
If you don't already have JDK installed, download and install from the official JDK downloads page.
Generate a Keystore file (if you already don't have one).
keytool provided by the JDK:
keytool -genkey -v -keystore my.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias app
Make sure to save the generated Keystore file and its password somewhere safe. You'll need them again if you ever decide to republish the app.
The last step is to sign the app with the previously generated Keystore. This is done using the
jarsigner tool provided by JDK.
The Jarsigner tool can be found in:
- Linux and MacOS: /usr/bin/jarsigner
- Windows: jdk/bin/jarsigner.exe
Use it like this:
jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my.keystore app.aab app
The signed ABB can be verified with:
jarsigner -verify app.abb
Publish App to the Google Play Store
Submit the Android app via the Play Store.
