.Create causes SIGABRT crash

[ruby0x1]

I've been trying out the SDK, but have ended up stuck with a hard to debug crash.
I would have filed this on the SDK repo but there isn't one, so this is the next best option since I'm using the code here as direct reference :)

The following line causes the crash, but only after it returns:
service = builder.Create(conf);

If I don't call create (but configure everything before it) it continues without issue.

Possibly relevant information:

• I am running a Nexus 5x, Android 6.0.1 (latest updates)
• Building on NDK r10e, SDK is up to date, compileSdkVersion 23
• Building with gradle/android studio
  • using compile 'com.google.android.gms:play-services:8.4.0'
  • I don't have any apply lines related to the play services
• I am using SDL 2.0.4 stable as the basis of the app
• The app ID is set up and configured on the developer console
• checkJNI is enabled
• I use JNI_OnLoad initialization

The code below is a bit verbose because I have been trying to debug this a while.

static std::unique_ptr< ::gpg::GameServices> service;

void init() {

 if(service == nullptr) {

 LOGI("INIT JVM:%p", jvm);

 JNIEnv* env;

 int state = jvm->GetEnv(reinterpret_cast<void**>(&env), JNI_VERSION_1_6);
 if (state == JNI_EDETACHED) {
 LOGI("INIT: GetEnv: not attached, attaching ... ");
 if (jvm->AttachCurrentThread(&env, NULL) != 0) {
 LOGI("INIT: GetEnv: FAILED TO ATTACH");
 } else {
 LOGI("INIT: GetEnv: ATTACHED OK");
 }
 } else if (state == JNI_OK) {
 LOGI("INIT: GetEnv: JNI_OK");
 } else if (state == JNI_EVERSION) {
 LOGI("INIT: GetEnv: JNI_EVERSION: version not supported");
 }

 LOGI("INIT ENV:%p", env);

 jclass localclass = env->FindClass("org/snowkit/snowbasic/AppActivity"); LOGI("local class %p",localclass);
 jclass globalclass = reinterpret_cast<jclass>(env->NewGlobalRef(localclass)); LOGI("global class %p",globalclass);

 jmethodID mid = env->GetStaticMethodID(globalclass, "getActivity","()Landroid/app/Activity;"); LOGI("mid %p",mid);
 jobject localactivity = env->CallStaticObjectMethod(globalclass, mid); LOGI("local activity %p",localactivity);
 jobject globalactivity = reinterpret_cast<jobject>(env->NewGlobalRef(localactivity)); LOGI("global activity %p",globalactivity);

 ::gpg::AndroidPlatformConfiguration conf;
 conf.SetActivity(globalactivity);

 ::gpg::GameServices::Builder builder;

 builder.SetDefaultOnLog(::gpg::LogLevel::VERBOSE);

 builder.SetOnAuthActionStarted([&](::gpg::AuthOperation op) {
 LOGI("OnAuthActionStarted");
 });

 builder.SetOnAuthActionFinished([&](::gpg::AuthOperation op, ::gpg::AuthStatus status) {
 LOGI("AuthActionFinished, status: %d", status);
 });

 service = builder.Create(conf);

 LOGI("INIT: DONE");

 } //service != null

} //init

I have explicitly added the getActivity function to check that it was sane.
The selfActivity instance is set inside of onCreate.

 public static Activity getActivity() {
 Log.i("APP",">>>>>>>>/ Get Activity / " + selfActivity);
 return selfActivity;
 }

And finally, here is the logcat output at the time of the crash.
In case it's not clear:

Debugging via Android studio with NDK debugging yields minimal help,
Because it's an abort, I can't get lldb or gdb (via android studio or otherwise) to break properly once it triggers. All other stepping through prior is fine until it does, but the code reaches the end of it's execution before crashing (note the code prints done from inside the app on return of the init call).

Due to the nature of the abort it also makes it difficult to search for help, and all the common thread related issues are (or should be) accounted for above.

I have noticed this verbose log in other peoples issues on this repo: V/GamesNativeSDK(12369): Attached to JVM on thread 1927939016 but I never see this in my logcat, the only line from the sdk is the above one about the jar file.

Any help is appreciated!

Have you found a solution for this? I seem to be having a similar problem.

[claywilkinson]

I am not sure if this is related to Google Play Game Services? I don't see anything in the log snippet indicating it is related?
This line in the call stack:
F DEBUG : #08 pc 00631700 /data/app/org.snowkit.snowbasic-2/lib/arm/libsnow_basic.so (__cxa_pure_virtual+24)

Looks like to me that a class in snow_basic has an unimplemented virtual method or it the victim of a bad cast?

[ruby0x1]

execute_native_thread_routine is a function inside of the std/libc++ implementation...
Plus it's worth looking at the ones leading to it - I wasn't starting a thread via pthread_start that I'm aware of - it was just the create call and a crash.

@florin-chelaru : I hadn't gotten further trying to use this library after this error, adding the library to my project and calling create() caused this crash and at the time deadlines approached so I just implemented my own JNI stuff manually which worked fine.

[claywilkinson]

Good point. Thanks for the response.

[ruby0x1]

I'll see if I have the code around still, I tend to keep these kinda things for later debugging. Maybe I can reproduce it and see if there's more to go on.
