How to debug the Android App in release mode using Android studio

For some reason I have to run my Android App in release mode.I have to run through the code when running the app just like we use in debug mode. My break points are not hitting when I run in release mode, I have added android:debuggable="true" in manifest. Still the breakpoint is not hitting. Any help.

Thanks in Advance

In my case, I have created the debug configuration same as previous release build and started debugging. It means you have to give sign build in debug version also in build gradle.

signingConfigs {
    config {
        keyAlias 'abc'
        keyPassword 'xyz'
        storeFile file('<<KEYSTORE-PATH>>.keystore')
        storePassword 'password'
    }
}
buildTypes {
  debug {
      debuggable true
      signingConfig signingConfigs.config
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    }
}

So It will have the same sign as release build and you can debug when it runs.
