ConnectivityManager.requestNetwork in Android 6.0

Question

I\'m trying to get the new ConnectivityManager.bindProcessToNetwork(Network) using ConnectivityManager.requestNetwork(NetworkRequest, ConnectivityManager.Netw

Answer 1

I'm not sure if this was intended by Google, but the following is the behavior I'm seeing:

CHANGE_NETWORK_STATE seems to always be denied (as noted in the comments, its a signature permission) but it also doesn't seem to matter. My ConnectivityManager network requests all seem to be gated by WRITE_SETTINGS only - so if you have WRITE_SETTINGS you don't need CHANGE_NETWORK_STATE.

As noted in comments, you do this differently than other permissions, using:

 Intent goToSettings = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS);
 goToSettings.setData(Uri.parse("package:" + Context.getPackageName()));
 startActivity(goToSettings);

And after that, my ConnectivityManager network requests were peachy.

To check if the permission is already granted before calling the ACTION_MANAGE_WRITE_SETTINGS activity, this answer has the solution using Settings.System.canWrite(Context)

Can't get WRITE_SETTINGS permission

UPDATE: as of Android 6.0.1, CHANGE_NETWORK_STATE is auto granted when requested in your manifest file. The above WRITE_SETTINGS checks are only required for 6.0
