Uninstalling .apk file from Emulator for refresh issue

In the SDK's main directory (i.e. "C:/Programming/Android/SDK") there is the folder called "tools" --> Get into that folder. You need to start a console terminal/shell ("Start -> Run... -> type 'cmd'" for Windows PCs). Type-in sth. like the following command:

CODE: SELECT ALL

adb shell rm data/app/{myFile.apk}

For example if you want to uninstall "HelloAndroid.apk" you should type this:

CODE: SELECT ALL

adb shell rm data/app/HelloAndroid.apk
