My Android app was first intended for Android 2.2 onwards so I used
player.getSettings().setPluginState(WebSettings.PluginState.ON);
for the WebView object.
Now that I've decided to open my app to Android 2.1 users, I changed my code to this:
try {
player.getSettings().setPluginState(WebSettings.PluginState.ON);
} catch (Exception e) {
player.getSettings().setPluginsEnabled(true);
}
With this, the app force closes and I get this error on my logcat:
Uncaught handler: thread main exiting due to uncaught exception

Any help with this error?
EDIT:
This error only appears on the 2.1 emulator.
A bit late - I'm sure you've figured it out by now - but the error is caused by the class PluginState not being available on Android versions < 2.2 (API 8). See the android docs on PluginState.
The reason why you can't catch this with try {} catch (Exception e) {} is because the NoClassDefFoundError is not an Exception - it's an Error. While Error and Exception are both children of Throwable they are not the same, hence you cannot catch an Error with an Exception and vice versa.
To solve this you can take either of the following approaches:
Check which Android version the device is running, and only call PluginState when the device is running API-version >= 8.
In your catch()-statement, catch NoClassDefFoundError instead of Exception.
Also, Eclipse will most likely show a Lint-warning mentioning the PluginState-class is only available on API 8+. You can hide/ignore this warning by adding #SuppressLint("NewApi") to the line above your method.

Any idea why I get this exceptions. Its supposed to be very straight forward and simple. It compiles without any errors or warnings. At run time it throws exception.
Instrumentation im = new Instrumentation();
UiAutomation myVar = im.getUiAutomation();
myVar.injectInputEvent(evntDown,false);
Here's the exception.

UIAutomation was included in API 18. NoSuchMethod Exception occurs when you try to access/use a class/method that is not supported on OS/API version you are currently running the app on.
Running this in my android device gives me these errors.

I think these errors are related to Android NDK. Can anyone guide me on this, keeping in mind that I have no prior knowledge of Android NDK and how it works.
This may happen if we install the app on a device where the previous version was already installed we always get this kind of error:
Just look at this similar problem : https://groups.google.com/d/topic/android-ndk/YmKly4zEMQ0/discussion
I found the reason why I was getting this error, because I did not build the native libraries. I used ndk-build and the errors got resolved.
I have this exception that I get in my crash reports from Android:

I am pretty new to the crash reporting system in Android. Why would this crash happen? I can not reproduce it on my device or the simulator.
What other info is needed from the crash report to determine the cause and how to fix this?
Thanks!
apply() was introduced in API level 9, and some devices that runs your app may be with lower version. consider changing this call to commit. As stated in the docs:
The SharedPreferences.Editor interface isn't expected to be
implemented directly. However, if you previously did implement it and
are now getting errors about missing apply(), you can simply call
commit() from apply().
Read the documentation:
http://developer.android.com/reference/android/content/SharedPreferences.Editor.html#apply()
Look at the api version that it was started with.
There is an exceptions, which I got in Android on drag.
Google doesnt know about this exception.
Question:
Any Idea, what to override to catch this exception? Something seems to hppen inside of the system, because all the listed classes are frameworks native classes.

There is an exceptions, which I got in Android on drag. Google doesnt know about this exception.
Since I can't find a reportDropResult() in the Android 2.3 source, I am guessing that this is from the new drag-and-drop framework introduced with Honeycomb.
Any Idea, what to override to catch this exception?
You can't override anything to catch that exception. To catch unhandled exceptions, use Thread and setDefaultUncaughtExceptionHandler().
One of my Android users is getting a force-close when launching Google Map (MapActivity class) inside my application. He gets a MissingResourceException. He's the only one complaining so far, and he is using Vanilla Tazz phone. The Google maps application itself works well on his device. It looks like it's something specific to Vanilla Tazz. I tried to find a fix online but have not been successful. Here's the Android error log:

I would appreciate if anyone can suggest anything to fix this.
Not sure you'll find a fix for this: it sounds like the ROM was built without that resource as part of the OS image. They'll probably need a new ROM to get around that.
