Error I received while running my first Android App on Eclipse Classic- Failed to install HelloAndroid.apk on device 'emulator-5554!
Run the AVD Manager > Edit >Change Built in to HVGA > Save Changes (click on Edit AVD and close)
Then Run the App, it worked like wonders :P
An error occurs while creating AVD for Android 4 & above - "Unable to find a userimg.data file for ABI armeabi to copy into the AVD folder"
For that all you need to do is the following
Step 1) Open Eclipse and click on Run Configurations (pull down the arrow next to the Run or Debug button).
You need Eclipse Classic http://www.eclipse.org/downloads/
Then you need SDK starter package http://developer.android.com/sdk/installing.html
Lastly you need ADT plugin for Eclipse - which you can install from eclipse itself Help>Install New Software>Add, then paste the following link in Location
