How to get NDK debugging to work in Android Studio?

Question

Android Studio doesn't stop at breakpoints in C++ code, this is what i've done so far :

1. In AndroidManifest.xml :

   android:debuggable="true"
   

2. In build.gradle (this may be the problem):

   sourceSets.main {
     jniLibs.srcDir 'src/main/libs'
     jni.srcDirs = []
   }
   
   task ndkBuild(type: Exec) {
     commandLine android.ndkDirectory.getAbsolutePath() + '\\' + 'ndk-build.cmd', '-C', file('src/main/jni').absolutePath, 'NDK_DEBUG=1'
   }
   
   tasks.withType(JavaCompile) {
     compileTask -> compileTask.dependsOn ndkBuild
   }
   

   3. Configured the application as a native application on Android Studio

   4. Put breakpoints in C++ code

   5. Debug the app

This seems to work because it is saying : "Now Launching Native Debug Session" moreover I can pause the app with the stop button but no breakpoint is working.

Thank you for your help

By the syntax of your build.gradle looks like you don't use the experimental plugin for gradle, without it you wont be able to debug native c/c++ in android studio. For more information read this : Android NDK Preview
