App force closes with java.lang.NoClassDefFoundError: android/os/AsyncTask - android

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.

You are probably using or accessing something which is simply supported in higher android SDK, as the error shows here java.lang.Class.newInstanceImpl(Native Method).
I happened to have the same kind of VerifyError while I was using String.isEmplty();. It seems you have same kind of problem as the message showing error in java.lang.Class
Thrown when the "verifier" detects that a class file, though well formed, contains some sort of internal inconsistency or security problem.
Here is official docs
Possible causes:
You might have imported something which is using different support v4/v7 library version.
You are targeting something from a higher SDK version. In that case, update your support repository and SDK build version.
Thanks everyone for your support and answers, may be your answers are right but in my case I used extra variables in one method while I was testing, so this exception appeared. Now I get rid of redundant things in my code and it start working. It may help others.

java.lang.RuntimeException: Unable to create BackupAgent com.berlin.mobson.view.OsmandBackupAgent: java.lang.NullPointerException

Some users have reported this error via the android error reporting popup thing but I have no idea what causes it. I googled but I can't find any good leads.
Anyone know what causes this error?

My App is a Place finder that uses google Places api to get search results. (no the library, just the json urls)
osmand is
Mobile Map Viewing & Navigation for Offline and Online OSM Maps.
The source code is available here Osmand
May be you can remove osmand from the device and then debug the application using above code available.
Thanks
Looks like their BackupAgent implementation is having some problems. A temporary solution is unchecking "Back up my data" in settings->backup & reset. Long term the NPE has to be tracked down in the BackupAgent.

java.lang.NullPointerException at android.webkit.WebViewClassic.setBaseLayer(WebViewClassic.java:5377)

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.

IndexOutOfBoundsException at android.graphics.Paint.native_measureText(Native Method)

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.

Resources$NotFoundException report from wild

I just released an update and got an exception report from the wild after someone updated a previously working application.
The same code works on my phone, the resource is a raw file and not dependent on device, local dependent or anything.
I had a similar thing happen before while developing the update, I cleaned the project and it resolved it.
However this doesn't seem to be a good solution as I cannot verify the fix, don't want to just shove a version out in case it fixes the issue.
Any advice as to cause or resolution would be massively appreciated!

For anyone facing a similar problem my resolution as horrible as it is:
Prepare a new release deleting all intermediate generated files, doing a clean build and re-releasing.
I trapped all media player creation code in try catch blocks for resource not found exceptions and pop up a toast explaining to the user what has occurred and to contact for a resolution.
This is pretty nasty but given that this should never occur...
I haven't heard either way from the user that returned the crash report, I have had other good feedback since, I'll update if I hear further either way.
