Support for getStackTrace() and setStackTrace()
Hi Salomon,
We're in the process of integrating your plugin in our app.
It would be very beneficial to be able to manipulate the stack trace before sending the ANRError to Firebase Crashlytics, so we can group the ANR issues together in the console there. Crashlytics groups the issues based on the topmost frame in the stack trace, so we were thinking of adding a custom frame to the top to let Firebase know that it belongs next to other ANR issues.
I've tried using couple of methods inherited from Throwable, but they don't seem to be overriden in the ANRError class - getStackTrace() returns an empty array and setStackTrace() doesn't seem to do anything.
So my questions are:
- Is there a way to add a custom frame to the top of the stack trace in the ANRError?
- If not, do you plan to add the support for manipulating the stack trace of the ANRError?
BTW, thanks for creating this plugin and making it open-source! It's a lifesaver amidst the current shortage of ANR detectors 😃
It's possible to make it work in debug mode too
Re note:
Note that this will not enable the watchdog in debug mode, because the watchdog will prevent the debugger from hanging execution at breakpoints or exceptions (it will detect the debugging pause as an ANR).
You could easily work around this by checking android.os.Debug#isDebuggerConnected whenever you detect an ANR and just ignore it.
Can you think of any reason not to do this by default?
Watchdog send error to Fabric (Crashlytics)
Hello,
I implemented WathchDog in my project. Boot seem like it has problem with WatchDog version 1.0.3.
The logs were not send to Fabric although I catched the error . Please help me check it.
Here's the code
new ANRWatchDog().setANRListener(new ANRWatchDog.ANRListener() {
@OverRide
public void onAppNotResponding(ANRError arg0) {
Crashlytics.getInstance().core.logException(arg0);
}
}).start();
Thank you.
The fix is released in version `1.4.0`.
The fix is released in version 1.4.0.

Caught Exceptions having error object from ANRWatchDog not getting logged on Crashlytics Dashboard
Hi,
I am using ANRWatchDog to catch ANRs. It provides an 'error' object which I am logging to crashlytics. I am getting report upload complete logs for crashlytics but nothing appears on dashboard. Crashlytics is working fine at the same time for other types of caught/uncaught exceptions.
private ANRListener listener = new ANRListener() {
@OverRide
public void onAppNotResponding(ANRError error) {
try{
Crashlytics.logException(error);
} catch (Exception e) {
Logger.e(TAG, "Exception while sending ANR stacktrace to Crash reporter "+e.getStackTrace());
}
}
};
I have raised the issue with Crashlytics team as well. Wanted to know here if any known issue exists in ANRWatchDog.
Indirect Dependency on API Level 15
When I include ANR-WatchDog using gradle, I get the following error when I sync the Android Studio project:
Error:Execution failed for task ':app:prepareDebugDependencies'.
ERROR: Debug has an indirect dependency on Android API level 15, but minSdkVersion for variant 'debug' is API level 10
Is there any reason why API Levels lower than 15 aren't supported?
Few queries - Not exactly issue
I am using both ANR-Watchdog and Dropbox to catch app's anr.
I am seeing below given cases:
- When ANR-Watchdog is reporting the ANR at that time Dropbox is not having ANR entry.
- When ever ANR-Watchdog misses to throw the exception, at that time we are having Dropbox entry.
- very rarely we are seeing both Watchdog and Dropbox having same entries.
Could you please advice, which one of above should actually happen as per your experience?
Though i am seeing that ANRWatchdog is efficient than Dropbox. But because of watchdog missing few anr i had to introduce dropbox mechanism.
ANRError indeed is too big for Crashlytics. I convert errors into text files and upload to Firebase storage it is free and you can setup it from Android Studio.

Cannot download version 1.4.0
I added com.github.anrwatchdaog:anrwatchdog:1.4.0 but still cant find ANRWatchDog and ANRError
I tried it in the test app
dependencies {
// implementation project(':anr-watchdog')
implementation 'com.github.anrwatchdaog:anrwatchdog:1.4.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
}
Thread timeout?
Hey, this is a fantastic project and very useful indeed. I am using the below code for checking ANRs :
` // ANR Reporting
/*if (BuildConfig.DEBUG == false) {
new ANRWatchDog(5000 *//*timeout*//*).start();
}*/
new ANRWatchDog().setIgnoreDebugger(true).start();
// Prevent app termination
new ANRWatchDog().setANRListener(new ANRWatchDog.ANRListener() {
@Override
public void onAppNotResponding(ANRError error) {
// Handle the error. For example, log it to HockeyApp:
Intent cu = new Intent(UriActivity.this, CrashActivity.class);
if(error!=null) {
cu.putExtra("errorx", error.toString());
}
startActivity(cu);
}
}).start();
// ANR Reporting End`
My questions are
-
Do I need to insert above code for every activity to check ANRs or launcher activity itself is enough? Meaning, does it have context only for the current activity or has context of all activities in the app.
Lets say I launch another activity other than the launcher activity using a service, then will I get ANR on that particular non launcher activity? There can be a limit to number of parallel threads allowed on a particular android device that is why I wanted raise this question. Say I use above code in 5 activities, I will have 4 unnecessary parallel threads. -
Can I use it on any of my apps with commercial use? Is the license Open Source?
Thanks!
How can I get pid of Thread from ANRErro?

Suspiciously short list of threads when recording ANRError as Crashlytics non-fatal exception
Hi!
I integrated ANR-WatchDog to a Unity game using custom implementation of UnityPlayerActivity.
At first I released a game with the default behaviour of the ANR-WatchDog.
My app crashed due to unhandled ANRError and Firebase Crashlytics recorded something around 40 threads at this moment including UnityMain thread and others. I used setReportMainThreadOnly() because Crashlytics collects all threads by itself on fatal errors.
Then I turned this crash to a non-fatal using this code:
@Override protected void onCreate(Bundle savedInstanceState)
{
ANRWatchDog watchDog = new ANRWatchDog();
watchDog.setANRListener(new ANRWatchDog.ANRListener() {
@Override
public void onAppNotResponding(ANRError error) {
FirebaseCrashlytics crashlytics = FirebaseCrashlytics.getInstance();
crashlytics.recordException(error);
}
});
watchDog.start();
super.onCreate(savedInstanceState);
}
This code records ANRError as a non-fatal exception and Crashlytics attaches stack traces contained in ANRError. That is why you do not see setReportMainThreadOnly() here any more. But now crash reports a very short, containing only 8-10 threads. What is strange there were no UnityMain thread while this non-fatal was triggered in the middle of a gameplay.
Please help, any ideas on how to get full list of stack traces attached?
How to be sure if main thread is blocked or not?
Hi, I've found your project with how to detect ANR in Android and I found it very useful, thanks a lot. But there is a port that I don't quite understand that how do you be sure if main thread is blocked?
Your code:
public void run() {
setName("|ANR-WatchDog|");
int lastTick;
while (!isInterrupted()) {
lastTick = _tick;
_uiHandler.post(_ticker);
try {
Thread.sleep(_timeoutInterval);
}
catch (InterruptedException e) {
_interruptionListener.onInterrupted(e);
return ;
}
// If the main thread has not handled _ticker, it is blocked. ANR.
if (_tick == lastTick) {
ANRError error;
if (_namePrefix != null)
error = ANRError.New(_namePrefix, _logThreadsWithoutStackTrace);
else
error = ANRError.NewMainOnly();
_anrListener.onAppNotResponding(error);
return ;
}
}
}
The value of current _tick is passed to lastTick before Runnable _ticker is passed to main thread. Let's assume _tick is 0 which means lastTick is 0 as well. Then the watchDog thread is gonna sleep for 5s without interruption. Then the code check if the new _tick equals lastTick:
if (_tick == lastTick)
By that I saw that if the new value of _tick equals the value of lastTick then we know the thread is blocked. This is the part I just don't understand, isn't it possible that the new value of _tick is 0 since its value will be set between 0~9 (_tick = (_tick + 1) % 10)??? Is there anything wrong about my analysis about this? I knew that it has to be something wrong with myself but I just can't find out, hope somebody can help me, thanks a lot!
Anr is not being detected sometimes
I have an app, I made the app to cause the ANR by following code on tap of a button:
int i = 0;
while(true){
i++; // this will cause anr
}
The above code causes the ANR, app also shows the anr dialog (basically, app not responding, wait or close the app), but the problem is ANRWatchDog isn't able to detect the anr sometimes, sometimes it does.
Please have a look at the above issue reported and let me know.
Thanks!
sometimes it will not cash when I use the watchdog
I use the watchdog in my app, why sometime it will crash when anr, but sometimes the android os anr dialog will appear(then it will not crash)?
I just code it by the default way: new ANRWatchDog().start();
ExceptionHandler is missing
ExceptionHandler.saveException(error, new CrashManager());
Im currently using Crashlytics. How do I save exceptions using your code?
Ggv
I too was having this issue earlier, it seems when you Log a non-runtime exception in crashlytics it creates nonfatal exceptions in fabric dashboard since ANRs don't necessarily crash an application. You need to toggle the switch in the fabric dashboard to show all exceptions including non-fatals as by default it only shows fatal exceptions.

Another issue might be proguard which when enabled strips some important classes required by anrWatchDog. To prevent that use the following rule in your proguard-rules.pro file.
-keep class com.github.anrwatchdog.** { *; }
You might also want to do the following to change the error into string
anrWatchDog.setANRListener(new ANRWatchDog.ANRListener() {
@Override
public void onAppNotResponding(ANRError error) {
StringWriter sw = new StringWriter();
error.printStackTrace(new PrintWriter(sw));
CrashUtil.logException(new RuntimeException(sw.toString()));
}
});
Hope it helps!

Race condition for _tick and _reported
- Let assume that we use all the default callbacks and values.
- When the _ticker is not called during 5sec and we recognise this as ANR and send the report, assign interval initial value and set the _reported to true.
- We start our while cycle from the beginning: _tick is not 0 so we don't schedule _ticker again - it is ok, next we put our thread to the sleep on 5sec one more time.
- But imagine that our _ticker is not called again during this 5s but is called at the time when we step on condition "if (_tick != 0 && !_reported)" and it is race condition because we write and read _tick and _reported at the same moment of time.
Best,

看了下你的源码，原理比较简单，但是还是有不准确的情况
看了下你的源码，原理比较简单，但是还是有不准确的情况，因为你靠的就是UiHandler来实现你的目标代码是否响应了，来判断当前UI是否卡顿，表面上看是可信，只是粗略上的数据。实际上，这样做不仅多起了一个线程去Dispatch 一个消息，性能消耗了，而且不能准确的判断到底是那个函数耗时了（通过消息队列来判断，实际上有时间差，不够精准）！
我觉得ANR监测的正确姿势还是要需要做AOP，这样才能准确的监控到每一个函数的调用时间，然后做精准的定位。
目前aspectJ已经做的很好，做这个完全是一个非常方便的事情，可以慎重考虑一下~~

ANR-WatchDog not works with Bugsnag
I'm not sure if the problem is with WatchDog or Bugsnag. We implemented WatchDog in our project but we have some problems with ANR errors - they aren't sent to Bugsnag, but with Fabric everything works correctly.
new ANRWatchDog().setANRListener(new ANRWatchDog.ANRListener() {
@Override
public void onAppNotResponding(final ANRError error) {
Bugsnag.notify(error);
throw error;
}
}).start();
Precompiled test app
It would be nice if you could provide the test app as pre-compiled apk, i need it to test some tasker stuff ^~^

please help me why this anr exception occur as it is very hard to debug anr exception
please help me how to solve this.
Main thread is in runnable state but still ANR is detected.
Hello,
We integrated your library and we are seeing some weird logs on our crashlytics, like below:
Caused by com.github.anrwatchdog.ANRError$$$_Thread
main (state = RUNNABLE)
The state is runnable but it still shows up as an ANR. Is this a false positive?
Exception thrown by ANR WatchDog not catchable by ACRA
Hi,
I was trying to use ANR WatchDog and ACRA to catch a bug, but when the ANR WatchDog triggers, ACRA doesn't actually catch the exception, but throws an error itself and therefore hands off the exception to the system, which then promptly kills the app. The error seems to be related to ACRA trying to serialize the exception generated by ANR WatchDog (see below).
I am using ACRA 4.8.2, and ANR WatchDog 1.1.*.
Any help would be greatly appreciated. Thanks!

where i can read anr report?
I hava import this libs to my project,and i create an anr,but i can't find where has the report?
Not really issues -- more like a couple questions
Android typically traps ANRs (at least for touch events) after 500ms. By having our ANR timeout higher than that is it possible we could ANR, present a wait/close message, answer close, before the watchdog's ANR event fires?
My thought is yes. Do you see any ramifications about running with a 500 ms timeout in production? I'm only talking about the main thread monitor. I do my own sleeps in other threads that would definitely trip it if I were monitoring them too.
The next comment is really more an annoyance with Google. I absolutely hate not being able to interrupt and join ANRWatchDog onTerminate() because for whatever reason Google refuses to give us a means of (easily / logically) determining when an application closes.
I have the following in my onTerminate() but I know it will never be called. I'm guessing this why you simply just create an anonymous instance in all your examples, correct?
anrWatchDog.interrupt();
try {
anrWatchDog.join();
} catch (InterruptedException e) {
Crashlytics.logException(e);
}
if (_namePrefix != null) should be if (!TextUtils.isEmpty(_namePrefix))
if (_namePrefix != null) should be if (!TextUtils.isEmpty(_namePrefix)) .
Because if I ignore setting the only main Thread, error = ANRError.New(_namePrefix, _logThreadsWithoutStackTrace) will be executed, but it is not efficient.
// If the main thread has not handled _ticker, it is blocked. ANR.
if (_tick == lastTick) {
ANRError error;
if (_namePrefix != null)
error = ANRError.New(_namePrefix, _logThreadsWithoutStackTrace);
else
error = ANRError.NewMainOnly();
_anrListener.onAppNotResponding(error);
return ;
}
Real ANR timeout
I tested your library and I found that reaction on ANR is much bigger than the value set in constructor by new ANRWatchDog(10000 /*timeout*/).start();
I found that it is caused by this code
try {
Thread.sleep(interval);
} catch (InterruptedException e) {
_interruptionListener.onInterrupted(e);
return ;
}
If there is no ANR, your thread basically sleeps for 10000 ms in this case.
During this 10s can happen that thread is blocked, for example in the middle.
So it is already 5s blocked at the end, but tick has arrived before it happens.
So it will sleep again 10s, and then it detects ANR after 15s.
So theoretically it can be almost double of configured time.
The only workaround is to use low timeout interval, for example, 500ms
And then use ANRInterceptor and detect real 10s here.
But this behavior is not clear from the documentation.
I am getting anr exception, don't know what is root cause

It seems not so good to start the anr-watchdog on application oncreate
If using new ANRWatchDog().start() on application oncreate function. then it will begin to post a delay message(defalut 5000ms), while on application oncreate function, there may be init some tasks in UI Thread may need more than 5000 ms with some low mobile devices, thus it will cause the not real anr with anr-watchDog.
Debug.waitForDebugger() conflict
When I place Debug.waitForDebugger(); into some method there's always ANR. setIgnoreDebugger() is not set.
Expected: watchdog does not throw on Debug waits.
Anr is not being detected for android 8.0
ActivityManager: ANR in XX
Reason: Context.startForegroundService() did not then call Service.startForeground(): ServiceRecord{XX}
onAppNotResponding not working properly
Hi ,
As mentioned in doc about onAppNotResponding call back.
It is said final user will not get app not responding dialog if we override this function.
But I used below code :-
new ANRWatchDog().setReportMainThreadOnly().start();
new ANRWatchDog().setANRListener(new ANRWatchDog.ANRListener() {
@OverRide
public void onAppNotResponding(ANRError error) {
if (!isDebuggerConnected()) {
throw error;
}
}
}).start();
And I am getting App Not responding dialog.
Kindly help me.

I've implemented WatchDog in my project. But it has some problem with Fabric.
I catched the error then sent ANR error to Fabric but it seem not work
