<p>On devices before SDK version 23, the permissions are automatically granted if they appear in the manifest, so <code>check</code> should always result to <code>true</code> and <code>request</code> should always resolve to <code>PermissionsAndroid.RESULTS.GRANTED</code>.</p>
<p>If a user has previously turned off a permission that you prompt for, the OS will advise your app to show a rationale for needing the permission. The optional <code>rationale</code> argument will show a dialog prompt only if necessary - otherwise the normal permission prompt will appear.</p>

<p>On devices before SDK version 23, the permissions are automatically granted if they appear in the manifest, so <code>check</code> should always result to <code>true</code> and <code>request</code> should always resolve to <code>PermissionsAndroid.RESULTS.GRANTED</code>.</p>
<p>If a user has previously turned off a permission that you prompt for, the OS will advise your app to show a rationale for needing the permission. The optional <code>rationale</code> argument will show a dialog prompt only if necessary - otherwise the normal permission prompt will appear.</p>
