Reinstallation failed due to various application signatures

Why change the application signature in Android after changing the class?

I started getting errors in my Eclipse workspace for several, but not all of my projects. I noticed that these are the oldest projects. I found error help and created my own debug.keystore and changed the Java build path to this folder.

Now, when I try to start any of the projects in the emulator, I get this error:

[2011-04-19 10:11:20 - enga] Re-installation failed due to different application signatures. [2011-04-19 10:11:20 - enga] You must perform a full uninstall of the application. WARNING: This will remove the application data! [2011-04-19 10:11:20 - enga] Please execute 'adb uninstall com.engatest' in a shell. [2011-04-19 10:11:20 - enga] Launch canceled! 

I tried to remove the application from the menu in the emulator, go through the movements and drag it to the trash, but it is not deleted.

I tried running in the terminal: adb uninstall com.dwclogic.engatest but the command was not found, adb is probably not configured globally on my mac. I am new to Mac and don't know how to get the execution path for this fixed, but this is another problem.

Where can I run this command? Are there any other ways to fix this problem.

Answer 1

• You can remove the application in your emulator using "Settings-> Applications-> Application Management". There you can see a list of all installed applications. If you then click on the application you want to uninstall, a screen with the uninstall option opens.
• The second uninstall option is to use "adb uninstall". adb is a command line tool located under the Android SDK folder. You can find it there in a folder called "platform tools." So you need to go to your SDK installation and use the terminal window to run adb there.

Dragging the icon to the trash does not delete the application. It removes the icon only from the main screen.

Answer 2

I get this error when my physical device is connected to the USB port of your PC. If you are connected to a network, try disconnecting it.

Answer 3

Go to Settings → Application → Application Management → “tab of your application” → delete

Launch the app from Eclipse again and it will definitely work for you.
