Answer 1

Close your eclipse and AVD both and start again everything will be fine.

• Muhammad Sohail: i have made another AVD with less API level that is 14 but when i run the app there comes the emulator with the Android animated label.. nothing more although i waited a lot but when i see the eclipse window there was error messages in the console window that are [2012年02月19日 21:17:39 - Emulator] NAND: nand_dev_load_disk_state ftruncate failed: Invalid argument [2012年02月19日 21:17:42 - Emulator] savevm: unable to load section nand_dev [2012年02月19日 21:18:57 - LunchList] emulator-5554 disconnected! Cancelling 'apt.tutorial.LunchList activity launch'!
• Muhammad Sohail: THANKS ALLAH it worked now..... i made a new AVD with API level 10 and with Google API and when i run the project it showed the output...

Answer 2

try to run in your command prompt:

adb kill-server adb start-server

this is to restart the Android Debug Bridge. If you have any problem running the command above, try to check if adb in in your path environment variable.

Answer 3

Try to remove BackCamera and Snapshot from Emulator, it worked for me.
