Android studio does not Generate Signed APK

Question

The Problem is that , I'm getting error while generating Signed APK using Allatori Java Obfuscator . I tried different hacks like, Invalidate and Clear cache /Restart ,by deleting build folder, rebuilding project, Strings , Even tried comparing package names ,Class Naming conventions, possible jars , deprecated methods or classes but Its of no use.! Multi Dex is enabled as well.! and I tried every possible Solution but unable to generate signed APK .

apply plugin: 'com.android.application'
apply plugin: 'ensighten'


ext {
    supportVersion = "25.3.1"
    googleServices = "11.4.2"
}

android {

    def version = "2.0.0"
    compileSdkVersion 25
    buildToolsVersion '26.0.2'
    defaultConfig {
        applicationId "removed"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 20
        versionName "${version}"
        multiDexEnabled true


        def today = new Date().format('yyyyMMdd_HHmmss').toString()
        project.ext.set("archivesBaseName", "MyApplication_Android_Build_"+ today + "_Version " + version);

Answer 1

As per my knowledge you are using lot of libraries and using Allatori Java Obfuscator due to Allatori obfuscation your java code is not being properly converted into byte code and thats the reason you are unable to generate signed apk. Try a quick hack delete build files ,gradle files and invalidate and restart your project more than once

Hope this may help u :)

Answer 2

There is no Signing config in Gradle you have added, So first Create a Keystore ( https://developer.android.com/studio/publish/app-signing.html )

and then add in the app level Gradle

signingConfigs {
    release {
        // For making app store release config below parameters
        storeFile file('path to keystore')
        storePassword "keystore password"
        keyAlias "Alias_of_keystore"         
        keyPassword "Keystore Password"   
    }
}

after that in build types add

 buildTypes {
    // For  app store release uncomment below and select release build flavor in Build Variants
    release {
...
signingConfig signingConfigs.release
}}
