ADT now can be used to debug android so file in sourcecode mode, but still bugs and flaws Android Studio can be used to debug android project with jni code, by run ndk-debug configuration in "Edit Run/Debug Configuration" during the debugging, it will first compile so and apk files, then follows:

adb push 1.apk /data/local/tmp/1.apk am start -D -n com.example.test/.MainActivity waiting for app's status to be debuggable set java-layer-breakpoints adb push lldb_server ./lldb_server ..............setup lldb server lldbfrontend.exe ........... connect to lldb server send cmmand to lldb_server to attach to some pid set jni-layer breakpoints remote connect to app and resume app running

I cracked android-ndk.jar to make the process up there directly establish jni-layer debug, and finally it works!!! you can use the source code i cracked by follow steps: export the eclipse project to android-ndk.jar replace android-ndk.jar used by android studio, or install it as a plugin(must uninstall the origin), remember to bake up restart android studio, open an existing android project with jni code start app by hand, and make changes in "Run/Debug Configurations" in android studio, you shall see a process list select the process you have just launched, press ok, and you will return to main window press debug button, wait for a moment, you will see some info about attached to app enjoy it!
