When developing Android applications, it’s common to install and uninstall apps frequently as part of the testing process. However, developers sometimes encounter a perplexing issue: the adb uninstall command returns a “Failure” message without any clear reason, as reported by developers using devices like the Samsung S2.
This guide aims to provide solutions to this problem, ensuring that your development workflow remains uninterrupted.
Understanding the Issue
Typically, when an app doesn’t show an uninstall button in the device’s application management settings, or when the adb uninstall command fails, it indicates a problem with the app’s installation or its registration in the Android system.
Steps to Resolve ADB Uninstall Issues
Before proceeding, ensure that your device is in developer mode with USB debugging enabled and you have ADB installed on your development machine. Here’s what you can do to uninstall an application:
Using ADB Uninstall
The straightforward approach is to use the adb uninstall command followed by the package name of the application you wish to remove:
adb uninstall com.example.yourappReplace com.example.yourapp with the actual package name of the app you’re trying to uninstall.
Using Android’s Package Manager
If the above method doesn’t work, you can try using the package manager directly within the ADB shell:
adb shell
pm uninstall --user 0 com.example.yourappHere, --user 0 specifies the main user profile on the Android system. Again, replace com.example.yourapp with the actual package name.
Identifying the Package Name
If you’re not sure about the package name, you can list all installed packages and search for your app’s name:
adb shell pm list packages | grep "partial_app_name"Additional Considerations
- Ensure the app is not set as a device administrator. If it is, deactivate it before uninstalling.
- Check if “Instant Run” is enabled in your IDE settings and consider disabling it.
- If your app is an internal system app, you might need root access to uninstall it.
- Ensure no emulator or other devices are connected that might interfere with the ADB commands.
