bluetooth - Send file to android device 4+ without selection picker -

-

good morning,

i'm newer in android i'm working on android project send file specific device, got bluetooth device don't need use intent need send selected file device. make research , try use bluetooth share dont work on device 4+ because exception need granturipermission question how set granturipermission? there method send items automatically device without user interaction?

here code try :

 contentvalues values = new contentvalues();              values.put(bluetoothshare.uri, uri.getpath());              values.put(bluetoothshare.destination, device.getaddress());              values.put(bluetoothshare.direction,  bluetoothshare.direction_outbound);              long ts = system.currenttimemillis();              values.put(bluetoothshare.timestamp, ts);

i try use intent this

     intent sharingintent = new intent(android.content.intent.action_send);       sharingintent.putextra(intent.extra_stream, uri);       sharingintent.putextra(bluetoothdevice.extra_device, device);      packagemanager pm = manager.this.getpackagemanager();     list<resolveinfo> appslist = pm.queryintentactivities( sharingintent, 0);     string packagename = "";     string mclassname = "";     if(appslist.size() > 0 ){           for(resolveinfo info: appslist){             packagename = info.activityinfo.packagename;             if( packagename.equals("com.android.bluetooth")){                 mclassname = info.activityinfo.name;                  break;             }         }      }        sharingintent.setclassname(packagename, classname);         sendbroadcast(sharingintent);
