I have opened the Android Emulator for my first set of code change. Then later i change some of my code. Should i want to close the emulator and relaunch (re-run) the code to reflect my new changes? or else simply pressing run key in eclipse will reflect the changes?

Please clarify.

PS : Till now, i wont close and relaunch the emulator for every code change. But today i faced the error in console like “Application already running, uninstall the application and try”. That’s why i have doubt on this.

    You do not need to relaunch the emulator, pressing the Run button in Eclipse will work.

    When you receive a message similar to this one:

    Re-installation failed due to different application signatures.
You must perform a full uninstall of the application. WARNING: ...This will remove the application data!
Please execute 'adb uninstall com.antew.code' in a shell.

    Open a command prompt and use:

    adb uninstall <package name>

    e.g.

    adb uninstall com.antew.code

    Then relaunch the application from Eclipse to install it again. The adb exe is in the /platform-tools/ folder of the SDK.
