Android minifyEnabled true is not working in Debug and Release mode

Question

I cannot able to run apk using minifyEnabled true in Debug and Release mode.I have referred below links but none worked for me.

1.Android- Error:Execution failed for task ':app:transformClassesWithDexForRelease'

2.Error converting bytecode to dex: Cause: java.lang.RuntimeException: Exception parsing classes - Android studio 2.0 beta 6

Below is my application build.gradle file

apply plugin: 'com.android.application'

    }

        jni.srcDirs = [] //disable automatic ndk-build call
        jniLibs.srcDir 'src/main/libs' //integrate your libs from libs instead of jniLibs
    }

Please help me with this.Thanks in advance.

Answer 1

Try after adding this to your proguard-rules.pro

-dontwarn javax.naming.**
-dontwarn javax.servlet.**
-dontwarn org.slf4j.**

If you are stuck with proguard. then do remove this for now.

 buildTypes {
        release {
          //  minifyEnabled false
          //  proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
        debug {
          //  minifyEnabled false
          //  proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
