I published an Android application that uses ACRA for crash reporting. Now I got a strange crash report:
java.lang.NullPointerException
at android.webkit.WebViewClassic.setBaseLayer(WebViewClassic.java:5377)
at android.webkit.WebViewClassic.setNewPicture(WebViewClassic.java:10781)
at android.webkit.WebViewClassic$PrivateHandler.handleMessage(WebViewClassic.java:10012)

at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:773)
at dalvik.system.NativeStart.main(Native Method)
The report was sent from a Samsung Galaxy S3 (GT-I9300) running Android 4.1.1. The report is strange (from my point of view) because my app doesn't use a WebView (no display of web pages in the whole app, no HTML handling at all). Furthermore the stack trace doesn't include any of my packages. Certainly I cannot reproduce the crash.
Has anybody else encountered this (or a very similar) stack trace? Why is this exception thrown? And what can I do to avoid the exception? Any help is really appreciated.
This can be caused due to use of external ad networks that may use WebViews. This is a problem that needs to be addressed by the ad network maintainers. Apart from bringing it their attention, there is really nothing you can do about this short of removing the offending providers' ads from your application.

Background
My app has a small PlusOne button in it (using Google-Play-Services rev. 21.0.2) , and recently I got the next crash report from one of the users
java.lang.NoClassDefFoundError: android.os.AsyncTask

The problem
I've followed all of the instructions of the Play Services for a very long time (including the Proguard part), and never had this issue before.
The weird thing is that I've succeeded running the app on multiple devices without any issue, and there are quite a lot of users out there that use my app . Many also uninstall, but this is the first time I get this crash.
The question
I'm not a Proguard expert, but is it maybe possible that this is the reason for it?
What could be the reason for this issue?
How can I fix this issue?
I've tried to search for this problem and there isn't even a single website that I've found regarding it.
Recently my app on Google Play Store get a lot of NPE of DeviceMotionService. Following is the stack:
java.lang.NullPointerException
at android.webkit.DeviceMotionService$2.run(DeviceMotionService.java:103)

at java.lang.Thread.run(Thread.java:856)
I have no clue about this issue. I did use WebView in my app. But I checked source code. It seems a deep function in android framework/webkit.
I recently got this crash report from what looks like a flurry library crash on my app:
java.lang.StackOverflowError

at android.os.HandlerThread.run(HandlerThread.java:60)
Has anyone seen this or is familiar with it? I don't even know what caused it as it does not say what file caused the problem.
Any thoughts on how to prevent this?
I would recommend you to update to SDK v3.0.5 which includes a fix to prevent crashing of bad phone ids in AndroidSDK 2.2.
(Full disclosure: I work in the Support team at Flurry)
We recently introduced OAuth login in our app. This means using a WebView to authenticate the user, and an AsyncTask to do necessary REST calls afterwards.
Unfortunately, after introducing this login method, we're getting reports of the app force closing. This seems to be related to other AsyncTasks that are executed after the login, but the stack traces does unfortunately not tell us much:

We managed to fix the error above by using RoboAsyncTask (from RoboGuice), instead of AsyncTask from the Android SDK, but we have other activities that use WebViews. WebView apparently uses AsyncTask somewhere in its call stack, and errors similar the one shown above (Caused by: java.lang.NoClassDefFoundError: android/os/AsyncTask) have started to show in our error logs.
The error happens on different devices, and different Android versions, with no apparent pattern. We have tried to reproduce the error ourselves, without any luck.
Any ideas?
It might be an issue with the build setup. (Build order of src/gen has been known to cause some issues, the libs folder for the compat library being called lib has caused some issues for me on new sdk versions).
To see if it is create a new project (in eclipse, since that's 100% android official). Add a webview and an asynctask and then do a diff on the project with your project. Ignoring src/gen/res. Hopefully you'll find that the src/gen are built in the wrong order or something like that.

I have an android app on Google Play and occasionally get the following error reported through the developer console / ACRA. The app runs fine on my test devices and on the various AVDs that I test it on.
The stack trace doesn't state where in the app the problem is. Is there anything I can do to narrow down where to look? What generally causes the error?

From the look of this, you have a race in your application initialization block. Probably one of your text resources is not fully inflated before a draw is issued. (i know, the model of the android runtime should prevent this, but if this happens when the layout is calculated, it would be plausible).
Hope this is of some help in narrowing it down.
