when you run the application you must send the lat / long by
Emulator control

you can get Emulator control from the

menu :
window - >Show view - > Emulator Control

and send manual lat log

    Bitmap bitmap = ((BitmapDrawable)dra).getBitmap();
        System.out.println(" SAve To Image :"+bitmap);              // you see the bitmap

WHY DEVELOP FOR ANDROID ?

If you have a background in mobile application development, you don’t need me to tell you that:
. A lot of what you can do with Android is already possible.
. But doing it is painful.
Android represents a clean break, a mobile framework based on the reality of modern mobile devices
designed by developers, for developers.
With a simple and powerful SDK, no licensing fees, excellent documentation, and a thriving developer
community, Android represents an excellent opportunity to create software that changes how and why
people use their mobile phones.
From a commercial perspective Android:
. Requires no certification for becoming an Android developer
. Provides the AndroidMarket for distribution and monetization of your applications
. Has no approval process for application distribution
. Gives you total control over your brand and access to the user’s home screen

how can you show image with a text in list view android
