This revokes the permissions to all user installed apps on update. Likely an expected quirk of being on 20.0 without the permission. 19.1 upgrades and new 20.0 installs should be fine. TODO: update 19.1 with the SpecialRuntimePermAppUtils too Signed-off-by: Tad <tad@spotco.us>

Subject: [PATCH] improve compatibility of INTERNET special runtime permission
|
|
|
|
There are apps that refuse to work when they detect that INTERNET is revoked, usually because of
|
|
a library check that reminds the app developer to add INTERNET uses-permission element to app's
|
|
AndroidManifest.
|
|
Always report that INTERNET is granted unless the app has
|
|
<meta-data android:name="android.permission.INTERNET.mode" android:value="runtime" />
|
|
declaration inside <application> element in its AndroidManifest, or is a system app.
