Magic number did not match while generating signed apk

Question

I am trying to generate signed apk but I am getting the following error.

I have searched about it but didn't find anything that can resolve this problem.

Solution I've tried

• Invalidate caches/restart

• deleting .gradle folder

• uninstalling android studio

I have recently updated studio with latest version 3.0.1, it was working fine though, the problem started since last few days.

Please some one help me with this!

Answer 1

Add multiDexEnabled = true in defaultConfig:

defaultConfig {
    applicationId "com.chigz.awesomegallery"
    minSdkVersion 16
    targetSdkVersion 27
    versionCode 4
    versionName "1.3"
    multiDexEnabled = true // important
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

Answer 3

I have got myself into same problem few day ago. What works for me is using different JDK versions. In order to resolve this issue follow steps by How to specify the JDK version in android studio? answered by Ben Kane. And do clean build after done.
