This sample shows how to update Android app silently without user confirmation with a device owner app. It works on Android 6.0 and higher.
For more information see https://sisik.eu/blog/android/dev-admin/update-app
Usage
- Build app and install on device
adb install -r -t app.apk
- Set app as device owner
adb shell dpm set-device-owner eu.sisik.devowner/.DevAdminReceiver
For Android 7.0 and higher you also need to set the
testOnlyflag in AndroidManifest.xml
- Increment versionCode of the app and rebuild again.
On Android 7.0 and higher you might need to remove the
testOnlyflag from AndroidManifest.xml again for the updates
- Push the new APK with updated versionCode to the device
adb push app-update.apk /data/local/tmp
- Start the device owner app (first version) and click on the button in the app. This should install the new version of the app from the specified location. The app should then automatically restart and show the new version.
