Is the request for internet persmission required at runtime (Android)?

阅读更多关于 Is the request for internet persmission required at runtime (Android)?

问题 For Android, it is required that we ask permissions at runtime to make sure users understand better why en when permissions are needed. I know this is true for permissions like WRITE_CALENDAR and ACCESS_FINE_LOCATION but it seems it's not required for INTERNET. Not strange because almost all apps use internet. Is it safe to say that I only need to declare it in the manifest? <uses-permission android:name="android.permission.INTERNET" /> Or should I always check it at runtime? 回答1: No, you

I have the app that uses <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> It's automatically granted on Android 6.0, but I can revoke it in the settings. Wanted to check if it's granted in case user revokes it, so I do this: int permissionCheck = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE); if (permissionCheck == PackageManager.PERMISSION_GRANTED) { //OK permission granted, let's do stuff } else { //I'll better ask for permission } Funny thing is that the condition is ALWAYS fulfilled, even the permission was revoked manually.
