I am using cocos2dx v3.9 with ndk 10e with android 4.4.2 .I have created a layer and on that button is present . When button is pressed layer is removed from parent and clean up is performed and other task is performed. Crash is coming when button is pressed, mostly when tapped as soon as button appears.
code on button click is:-
CocosDenshion::SimpleAudioEngine::getInstance()->playEffect("tap.wav");
unschedule(schedule_selector(InstructionLayer::callNextButtonMethod));
if (this->delegate != NULL) {
delegate->clickNextButton();
} else {
CCLOG("Delegate null");
}
this->removeFromParentAndCleanup(true);
}
and my ndk crash dump is :-

I am getting a lot of ANR's in ContentResolver in Firebase Crashlytics since updating all external google libraries and targetSDKVersion 32.
Are there any changes for ContentResolver I have missed in newer libraries/Android version?
For example, I get an ANR if I call my ContentResolver to get only a count:

I have not changed any code, so I am wondering why this is now happening after upgrading. I think I have missed any background changes in AndroidX or Android SDK 32 version for ContentResolver or queries.
I know this is very generic, but currently I don't know where to check for the problem.
I would be grateful for any help or hint.
Update 28.09.2022:
I get also sometimes ANR's where no class is involved of my app.

Seems the problems were about the upgrade from the Billing Library 3.x to 5.x!
After reverting to 3.x the ANR's are gone.
Now I have readded the Billing Library from scratch with version 5.x!
No more ANR's or strange behaviors anymore.
Strange, but I think there was a mistake on upgrading to 5.x and this caused some leaks.
I have a native Android, SDK style library which depends on OpenCV.
In order to avoid conflict when a user uses the library and their own usage with OpenCV, I want to compile OpenCV statically into my library and hide its symbols.
I compiled OpenCV (3.4.13 world module) statically and used it, along with its 3rd party libraries in my library.
When I try and use my library, and it throws an exception, even if the exception is caught by the user, a SIGABRT is causing the app to terminate.
This is the stack trace from the logcat
A/libc: Fatal signal 6 (SIGABRT), code -1 (SI_QUEUE) in tid 24115 (.test), pid 24115 (.test)

(It also happens if the JNI library uses c++_static, but in that case the __gxx_personality_v0 and 1 above it come from the libJnilibrary.so)
If I compile OpenCV as a shared library and link my library against it, then everything works fine.
I've had issues with exceptions in my library before, see this question I asked. I solved it by compiling everything using c++_static STL. The problem looks similar to this, and indeed I was missing the key function, but even after adding it, the problem keeps happening.
I looked at the symbols using llvm-readelf -CWs and noticed that when OpenCV is linked dynamically, in addition to OpenCV symbols, the output contains some ndk and cxxabi symbols which doesn't exist when OpenCV is used statically. I don't know if it's related at all but for example
110: 0000000000000000 0 FUNC GLOBAL DEFAULT UND std::uncaught_exception()
...
201: 0000000000000000 0 OBJECT GLOBAL DEFAULT UND vtable for __cxxabiv1::__vmi_class_type_info
...
231: 0000000000000000 0 FUNC GLOBAL DEFAULT UND std::__ndk1::to_string(unsigned int)
(All of these are missing when using statically built OpenCV)
I'm using ndk version 21e (I can't use higher version at the moment because another library uses Bazel and it only supports up to 21 at the moment)
OpenCV is built with the following flags
cmake -DCMAKE_BUILD_TYPE=Release -DINSTALL_ANDROID_EXAMPLES=OFF -DANDROID_EXAMPLES_WITH_LIBS=OFF -DANDROID_ABI="arm64-v8a"

My libray is compiled using Gradle and Android Studio with these CMake flags
externalNativeBuild {
cmake {
cppFlags "-std=c++17 -static-openmp -fopenmp -fexceptions -frtti -Wno-unused-command-line-argument -Wl,-s"
cppFlags "-Wl,--exclude-libs,libc++_static.a -Wl,--exclude-libs,libc++abi.a"
arguments "-DANDROID_STL=c++_static", "-DANDROID_ARM_NEON=TRUE"
}
}
The issue wasn't related to the 3rd party or anything like this at all eventually.
I was using NDK version r21e. Upgrading the NDK to r24 fixed the issue.
It seems that when linking OpenCV as a shared object, it masked the actual NDK bug by importing or including some of the missing/problematic symbols and when we stopped using it, the error appeared.
I'm developing the game on Unity 5.6.0f3 and I'm facing the problem with some Android devices. This crash reproduces not on every android device, but on soma of them, like this: LG Optimus L7II, LG Magna, LG Leon, Lenovo A680, Lenovo P780, Lenovo S580, Lenovo A3300, Lenovo S850, Lenovo A2010-a, ZenFone 5 (A502CG), ZenPad C 7.0 (Z170CG), HUAWEI Y3II, HUAWEI Y635-L01.
This crash occurs when my app is in background. This is it:

I'm using some native libs on C++ in my app and I thing that problem is in them.
I think that code can be the main problem:
#elif ANDROID
struct timespec res;
clock_gettime(CLOCK_MONOTONIC, &res);
std::chrono::milliseconds uptime = std::chrono::milliseconds(static_cast<unsigned long long>(res.tv_sec) * 1000ULL + static_cast<unsigned long long>(res.tv_nsec)/1000000ULL);
return uptime.count();
So please help if you know something about it, thank you;)

How do you compile the files?
It seems a problem with the script. The lines:
signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr ff7a8390

Signal 11 --> A memory fail, and the path go to nowhere. / are for paths in UNIX system, and \ to WINDOWS system, so something is wrong to find libc.so
A Bad file descriptor is a linux, if you get this error message while trying to access a file, the most prominent causes are file system corruption or damaged disk block(s). In such situations, you also get write errors.
I'm implementing OCR app which uses Tesseract API. When I press Android home button, popup window "Unfortunately has stopped" appears. I'm running TessbaseAPI multiple times in OCR thread with handler defined. I send messages with image for OCR purposes and thread process it.
After every image I call Tessbase's clear() and at Activity's onPause() method end(). There is probably problem in calling end() while image is processed. Does anyone have advice how to solve this? Thanks in advance.
