HelloAndroid]emulator-5554 disconnected! Cancelling 'com.example.helloandroid.HelloAndroid activity launch'!

Question

I am new to Android. Follow the HelloAndroid Tutorials by use Eclipse. After run HelloAndroid, the AVD \'xian_avd2\' lunched, but stop there, no \" Hello, Android\" display

Answer 1

For me, I believe it happened due to an unexpected power failure while the emulator was running. Having it not shut down properly meant that my session was still cached. (I would occasionally get these errors too):

[2012-06-08 05:05:06 - Emulator] WARNING: Data partition already in use. Changes will not persist!
[2012-06-08 05:05:06 - Emulator] WARNING: SD Card image already in use: C:\Users\Ben\.android\avd\Ben-Android.avd/sdcard.img
[2012-06-08 05:05:06 - Emulator] WARNING: Cache partition already in use. Changes will not persist!

If this happened to you, pull up the command line, navigate to your android-sdk\tools and follow the corrected top post: emulator -avd emulator_name -wipe-data

Answer 2

I resolved it (Mac) by following these steps,

• Run Emulator
• Keep the Emulator, (no matter same error occurs)
• Make Sure the Home Screen of Emulator is appeared
• go to Window -> Show Perspective -> DDMS --> In Devices Panel -> on Corner Drop Down Menu -> Reset adb

I Hope it helps
