Android - Alarm lost after app update

Question

I have an app running on Android that creates an alarm that is fired every 24 hours. This alarm is working as expected.

However, when I update my app through Google

Answer 1

Your solution is as simple as below:

Have a broadcast receiver registered within your app with 2 intent filters namely:

1. "android.intent.action.BOOT_COMPLETED" - called when you device restarts. Alarms are cancelled when device is shut down.
2. "android.intent.action.MY_PACKAGE_REPLACED" - called once your app is reinstalled or updated from play store or from any source.

You will also need the permission, "android.permission.RECEIVE_BOOT_COMPLETED". In this receiver you can start your alarms again.
