I am a web developer and have a web app (PWA) bundled into an Android app with Bubblewrap and I would like to prevent screen lock while the app is open.
I believe there is no solution involving JavaScript in the web app itself so I'd need an Android solution.
How can I make this happen?
I have found various answers on here that say I should either add <android:KeepScreenOn="true"/> to the Android manifest or add getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); somewhere in the code and I have tried to add these snippets in various places in the code, but without success.
Where should I add the code for it to work?
Any help would be appreciated. Thanks!
The AndroidManifest.xml of the project created by Bubblewrap is:
<!-- The "package" attribute is rewritten by the Gradle build with the value of applicationId.
It is still required here, as it is used to derive paths, for instance when referring
to an Activity by ".MyActivity" instead of the full name. If more Activities are added to the
application, the package attribute will need to reflect the correct path in order to use
the abbreviated format. -->
