I am getting a weird issue when using AutoCompleteTextView component on a device running on Honeycomb (Android 3.0) (using Motorola Xoom to test). I get a Nullpointer exception with the following stacktrace :

Note that I do not get this exception on any other versions of Android including Gingerbread. Its really hard to debug since I do not have the original source code of Honeycomb code base. I would appreciate if anyone can help me out.
Thanks,
Torri.
I had the exact exception. Everything works in 2.*, but in 3.x there all thrown this exception, and simply try catch didn't work.
Finally I found that, if I remove the below line from the view, then it worked for me:
android:dropDownAnchor="#+id/searchField"
I am not sure if this can help but I had a similarly weird problem with a button. It worked fine on all versions except 3.0
So I did this:
try{
mButton.setOnClickListener(...
//code...
}catch(NullPointerException e){
}
After this no more errors and guess what? The button works fine now on 3.0 !

Guys I am getting the below error in RunTime, what is the root cause of this error?

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.
I got the following exception reported several times in my ACRA reports. It seems to be coming only from devices running Android 4.4.2 but I have no idea where could be the problem.
Did anyone already meet this problem?
Thank you

UPDATE
There is this thread running: https://code.google.com/p/android/issues/detail?id=161400
Developers on the thread have the exact same problem, on devices running Android 4.4.2 only. It seems to be fixed on the other versions.
What work for me is
_editText.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
you can do this in xml file like
android:inputType="textNoSuggestions"
I thing by default this flag is true thats why it give this exception if give below 23 android version ,abouve 23 work fine
This is not the answer but until someone give answer to this question we can use above shortcut
Turn off suggestions like this:
android:inputType="textNoSuggestions|textVisiblePassword"
works better than just:
android:inputType="textNoSuggestions"
I published an Android application that uses ACRA for crash reporting. Now I got a strange crash report:

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.
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.
