Using Google Breakpad for Android NDK?

Question

Is anyone using Google Breakpad for Android native code (NDK) ?

If so, could you elaborate on how to get it up and running (the client side that is). The docs are ve

I also found a good example project for that. As it is in the project you can set up Google Breakpad like:

extern "C" {
    void Java_com_pluusystem_breakpadjavacall_MainActivity_initNative(JNIEnv* env, jobject obj, jstring filepath)
    {
        const char *path = env->GetStringUTFChars(filepath, 0);
        google_breakpad::MinidumpDescriptor descriptor(path);
        exceptionHandler = new google_breakpad::ExceptionHandler(descriptor, NULL, DumpCallback, NULL, true, -1);
    }
}

in the cpp side and like:

    // Save Dump Path
    initNative(getExternalCacheDir().getAbsolutePath());

in the java side.

After that implementing the bool DumpCallback(const google_breakpad::MinidumpDescriptor& descriptor, void* context, bool succeeded) function you will be able to do something before the app crashes.

I have experienced and also found this issue which confirms me, that in this function you can't do java callbacks under ART just under DVM (before android 5 - Lollipop).

Sorry about that, I did the initial port but I didn't really document anything. However, one of the Chrome engineers did some work on the port and wrote a really nice README: https://chromium.googlesource.com/breakpad/breakpad/+/master/README.ANDROID

There's also an NDK-compatible Android.mk file in there now, so if you're using the standard NDK build system it should be simple to incorporate Breakpad.
