i have internet permissions:
<uses-permission android:name="android.permission.internet" /> <uses-permission android:name="android.permission.write_external_storage" /> <uses-permission android:name="android.permission.access_wifi_state" /> <uses-permission android:name="android.permission.change_wifi_state" /> <uses-permission android:name="android.permission.change_network_state" /> <uses-permission android:name="android.permission.access_network_state" /> error looks this:

public boolean isstoragepermissiongranted() { if (build.version.sdk_int >= 23) { if (checkselfpermission(android.manifest.permission.write_external_storage) == packagemanager.permission_granted) { log.v(tag,"permission granted"); return true; } else { log.v(tag,"permission revoked"); activitycompat.requestpermissions(this, new string[]{manifest.permission.write_external_storage}, 1); return false; } } else { //permission automatically granted on sdk<23 upon installation log.v(tag,"permission granted"); return true; } } @override public void onrequestpermissionsresult(int requestcode, string[] permissions, int[] grantresults) { super.onrequestpermissionsresult(requestcode, permissions, grantresults); if(grantresults[0]== packagemanager.permission_granted){ log.v(tag,"permission: "+permissions[0]+ "was "+grantresults[0]); //resume tasks needing permission } }
obviously. targetsdkversion targeting 23 , need use runtime permission android.permission.write_external_storage android 6.0 include runtime permission feature. permissions considered dangerous permissions , need request @ run time. android.permission.write_external_storage 1 of them.
you can learn permissions dangerous , permissions normal here normal , dangerous permissions.
and can learn how use android runtime permission here: requesting permissions @ run time.
