Answer 1

I've tried all solutions and non of them helped! finally after many trying, I figured it out, just follow the tips:

1. copy your signature keystrok (that you use to release) inside yourProject/app/
2. gradle.properties (modify values related to your own key):

   MYAPP_RELEASE_STORE_FILE=KEYSTROK_NAME
   MYAPP_RELEASE_KEY_ALIAS=KEY_ALIAS
   MYAPP_RELEASE_STORE_PASSWORD=R_PASS
   MYAPP_RELEASE_KEY_PASSWORD=K_PASS
   android.enableR8=true
   

3. app level build.gradle (inside android):

   signingConfigs{
       release{
           if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
               storeFile file(MYAPP_RELEASE_STORE_FILE)
               storePassword MYAPP_RELEASE_STORE_PASSWORD
               keyAlias MYAPP_RELEASE_KEY_ALIAS
               keyPassword MYAPP_RELEASE_KEY_PASSWORD
           }
       }
   }
   
   configurations {
       cleanedAnnotations
       compile.exclude group: 'org.jetbrains' , module:'annotations'
   }
   
   

4. app level build.gradle (inside buildTypes):

   release {
       manifestPlaceholders = [analytics_deactivated: "false"]
       minifyEnabled true
       signingConfig signingConfigs.release
       useProguard true
       proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
   }
   

   5. finally this command:

mac: ./gradlew clean assemble_YOUR_FAVOR_Release

win: gradlew clean assemble_YOUR_FAVOR_Release

where _YOUR_FAVOR_ is your optional favor, if you are not using any favor, just simply use assembleRelease instead of assemble_YOUR_FAVOR_Release
