APK signing error : Failed to read key from keystore

Most likely that your key alias does not exist for your keystore file.

This answer should fix your signing issue ;)

Check your keystore file for first, in you example you creating file with name my-release-key.keystore. If its correct and really present in folder Users/bournewang/Documents/Project check alias, in your example it is -alias alias_name, but in config you specified alias mike

In order to find out what's wrong you can use gradle's signingReport command.

On mac:

./gradlew signingReport

On Windows:

gradlew signingReport
