APK signing error : Failed to read key from keystore
In order to find out what's wrong you can use gradle's signingReport command.
On mac:
./gradlew signingReport
On Windows:
gradlew signingReport
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
Most likely that your key alias does not exist for your keystore file.
This answer should fix your signing issue ;)
