"App has stopped working"

That message is what Androd OS throws at user so he knows something went wrong instead of application disapearing without any apparent reason. You should as developer know there is logcat that gives actual reason with details of what happend.

Here is the logcat which i got from my phone

 I/ActivityManager(  282): Displayed com.example.emeterfinalapp/.EmeterMainActivity:                +206ms
     I/ActivityManager(  282): Displayed com.example.emeterfinalapp/.EnterLocationActivity:      +224ms

i dnt know but i wl find out and come back to you wth further updates...thnx....

I do not know how Eclipse (surelly there is somewhere Android logging functionality), but IntelliJ when running project on USB connected device or even with emulator shows all events as happens on device. You can filter these events(info, warning, error etc) so you see when it crashes Dalvik error similar to JVM

Whoo...after scratching ma head for so long atlast i got the solution
first i did debugging with real device using DDMS following its documentation which is fabulous then i discovered the following error

12-12 15:08:29.458: E/AndroidRuntime(26382): java.lang.RuntimeException: Unable to start     activity ComponentInfo{com.example.emeterfinalapp/com.example.emeterfinalapp.SelectLocation}:     android.view.InflateException: Binary XML file line #17: Error inflating class fragment

and then after few more lines of code there was another error which was eye catching

  12-12 15:08:29.458: E/AndroidRuntime(26382): Caused by: java.lang.RuntimeException: API key not found.  Check that <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

and then i realised that my api key code is a child of manifest not application which the above error pointed out and then i rectified my manifest acordingly and everythng worked just perfectly...Debugging with real device helped a lot...Thanx peter...thanx a lot...

<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="my api key"/> 

This Code Should be Under The Application Tag
paste this code just befor aplicaion end Tag </application>
