We have written an Android application which sends stack traces to our server, if any occur. Sometimes we get weird stack traces that seem not to be an exception from our application. For example:
java.lang.NullPointerException
at android.widget.FastScroller.scrollTo1(FastScroller.java:306)
at android.widget.FastScroller.onTouchEvent(FastScroller.java:507)
at android.widget.AbsListView.onTouchEvent(AbsListView.java:1894)

There is no mention of our own classes, only Android's standard classes. It's obvious that this exception takes place when scrolling of item list (ListView) occurs, but I can't even uderstand how I can fix this bug. I can't reproduce this bug. What do you usually do when you encounter the same problem? Any ideas?
Tehere is something wrong with fast scrolling of some ListView using a thumb. If you set fast scrolling enabled of your ListView make sure the adapter class implements SectionIndexer.

I am wondering if this is some bug in Android Studio or I am simply lack od knowladge but straight to the point.
I am writing simple client-server via bluetooth app on android. At some point I encoured following problem:

For what I understand Android Studio can't find method parujUrzadzenia(View) that is marked in button6's properties as onClick method...the funny thing is i deleted this button in my way of solving this problem.
I can't post picture of my project due to low reputation but like I said. I've deleted the reference to method from .xml and method from .java file and got an error saying that there is no required onClick method. So I deleted this whole button and still got this error.
Any advices will be greatly appreciated.
I am using GA to tracking my applications. I have noticed that there is a weird exception reported sometimes on every release. The reported calling stack shows that it seems to be the Android issue of the user's device(I can never reproduce this issue). I tried hard but still cannot find a clue, is there anyone have some experience with this problem?

I don't understand why it is happening. Can someone help?
Use the new Google Play Services library which now include the Admob classes.
The Admob package has changed so your imports will need to be adjusted to
import com.google.android.gms.ads.*;
I'm seeing a weird exception in Android Support Library - the stack trace is below. Any ideas what could be causing this? I'm unable to reproduce the exception on any of my devices, but there seem to be quite a few visible in the Google Play DevConsole.

Updated to the latest version of AdWhirl and AdMob SDK but getting a known error from the AdMob SDK in Android 2.1-update1. Found in this thread https://groups.google.com/forum/#!topic/google-admob-ads-sdk/cNxRgIUHJH0
but it refers to only and AdMob fix not AdWhirl any clue what changes can be made to the AdWhirl SDK to fix this?
Thanks In Advance!

How about this one:

The issue is not in the AdWhirl code, or even the AdMob code. This is a NullPointerException in the Android WebView, and there is no known workaround for the AdMob/AdWhirl code. This shouldn't be happening that often, but if it really is a deal breaker, you may want to turn down the number of requests you're sending to AdMob.
Yes, I also have this problem.
My workaround: extend AdWhirlLayout, override dispatchWindowFocusChanged and every other method that have this exception occurring and catch the exception.
