Updating applications on Android devices outside of official app stores can present challenges, particularly when it comes to preserving user data and settings. This guide explores effective methods to update non-market APKs using Android Debug Bridge (ADB), ensuring that your app’s data and preferences remain intact.
Method 1: Using ADB Install with the -r Option
The most straightforward approach to updating a non-market APK is through the adb install -r command. This method performs an update by replacing the existing APK while retaining the app’s database and stored preferences. This ensures that user data is preserved, avoiding the complete reset that occurs with an uninstall/reinstall process.
Usage:
adb install -r your_app.apkThis command is particularly useful when you need to update the app without losing any saved data or settings, making it ideal for developers and testers who require a seamless upgrade process.
Method 2: Alternative Workaround for Persistent Data
In cases where adb install -r does not suffice, an alternative method involves uninstalling the app while keeping its data, followed by a fresh installation. This requires root access but ensures that the app data remains intact.
- Uninstall the app but retain its data:
adb uninstall -k com.packagename - Reinstall the app:
adb install your_app.apk
Note that this method is more complex and requires root permissions, making it less accessible for general users.
Handling Downgrades
If you need to install a downgraded version of an app, the adb install -r -d command can be used. This allows for the installation of an older version without losing data.
Usage:
adb install -r -d your_app.apkEnhancing Your Testing Workflow with Repeato
