We got ANR Problem in Google Play

Cocos Creator
#1

We’ve encountered several ANR (Application Not Responding) issues on Google Play, with the following output content. Has anyone else experienced similar problems?

#2

We have also encountered the same problem. Did you found a solution for this?

#3

Same for us:

#4

No, I am currently using this version.
Cocos Creator Version: 3.7.2
Target SDK: 33

I searched the forum. It seems that version 3.8.2 and above also have this problem.

#5

Could you please contact the users to ask them to record the game situation when the error occurs? Currently, we are unable to analyze the cause of the problem based on the error report.

#6

Sorry, We can’t contact our users.

But after I commented like this. The ANR is decreased.

static void onPause_native(JNIEnv *env, jobject javaGameActivity,
jlong handle) {
LOG_TRACE(“onPause_native”);
/*if (handle != 0) {
NativeCode *code = (NativeCode )handle;
if (code->callbacks.onPause != NULL) {
code->callbacks.onPause(code);
}
}/
}

#7

What is the expected percentage of reduction?

#8

We are currently at 2.07%, but should it be 0.47%?

This was mentioned by Google Play, which states: “Your 28-day user-perceived ANR (Application Not Responding) rate exceeds the bad behavior threshold of 0.47%. Your app is likely to be less discoverable on Google Play across all devices.”

#9

This issue was caused by a bug in android_native_app_glue within AGDK that resulted in thread lock blockages when switching between the foreground and background（pthread_cond_timedwait）, and it’s a widespread problem.

I’m unclear why Google hasn’t addressed it consistently.

We managed to resolve the issue by modifying android_native_app_glue and adding a stack structure to save the APP_CMD_PAUSE event of android_native_app_glue .
After nearly a month of observation, the ANR rate has dropped to just one third of its original rate.
Moving forward，I will consider pushing a PR to Cocos as soon as possible for them to assess whether to merge it into the engine.

On April 24th, we released a fix version, and you can see the comparison.
