Question

I am faced with this weird error. Whenever I start my application on my emulator, I get a message in the Emulator saying that Unfortunately,Search has stopped.

My LogCat also shows some error but after a few seconds, the application runs properly without any hassles.

But, every time I upload and install the application on the emulator I get this error.

I realise that it does not cause any trouble to the application as after the initial error, everything runs fine but still I would very much like to know the cause of such an error.

Here is what my LogCat displays.

Any idea what might be the cause ?

1. Make sure you correctly declared the android:name attribute of your application tag in the AndroidManifest.xml file.
