Unable to debug Native app on Android Studio

Question

I got this error when I try to debug a simple native android app with android studio:

Failed to attach native debugger: unable to attach 

I tied several ideas to solve it. But they didn't work for me.

more information:

• Ubuntu 16.04 (x64)
• java version "1.8.0_91"
• Android Studio v2.1.1
• gradle-experimental:0.7.0
• lldb 2.1

Do you have any idea?

UPDATE

After installing AVD (Android Virtual Device) on my pc (Ubuntu). Now I am able to debug both java and C++ codes. I think something wrong in my phone or lldb can not run in my phone (?). Do you have any Idea what does cause it?

My phone is HTC.

Your gradle-experimental setup should follow guidelines set forth by google. You can see their ndk samples of such here: https://github.com/googlesamples/android-ndk

Essentially, your android.ndk block in build.gradle should resemble this:

android.ndk { moduleName = "MostafaModule" cppFlags.addAll(['-std=c++11', '-fexceptions', '-Wall', '-Wno-literal-suffix']) cppFlags.add("-I${file("src/main/jni/mostafanativelib")}".toString()) ldLibs.addAll(["android", "log"]) stl = "gnustl_shared" }
