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

In your gradle file, you must add debuggable ability in your release flavor.

buildTypes {    release {        debuggable true        minifyEnabled false        signingConfig signingConfigs.release        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'    }    debug {        debuggable true        minifyEnabled false        applicationIdSuffix '.debug'    } }

signingConfig is release configuration it must be added in gradle file in android{} block, something like this:

signingConfigs {    release {        keyAlias 'YourAppKey'        keyPassword 'somePassword'        storeFile file('appkeyfile.jks')        storePassword 'somePassword'    }} 

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.

 buildTypes {    release {    debuggable true    minifyEnabled true    proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'}}

happy coding.Mark this answer up..if it helps.. :)
