I am getting the following error when i try to install my android app on tablet
ERROR:
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.spundhan.expensetracker' in a shell.
Launch canceled!
It clearly means that you did not installing the application properly so just either try to uninstall by going to
Setting=>manage application=>you application i.e expensetrackeror attached your device to computer and open command prompt and go to your android sdk like-D:\android\android-sdk-windows\platform-tools>adb uninstall com.spundhan.expensetracker
so it will uninstall your application properly and hope when you try to install it again you will not find any error.
