however, sure have camera-permission granted, because same code run in installed version.

can solve this? thank you!

here code went crash:

// camerafragment.java private textureview.surfacetexturelistener msurfacetexturelistener         = new textureview.surfacetexturelistener() {      @override     public void onsurfacetextureavailable(surfacetexture surfacetexture,                                           int width, int height) {         opencamera(width, height);     }      @override     public void onsurfacetexturesizechanged(surfacetexture surfacetexture,                                             int width, int height) {         configuretransform(width, height);     }      @override     public boolean onsurfacetexturedestroyed(surfacetexture surfacetexture) {         return true;     }      @override     public void onsurfacetextureupdated(surfacetexture surfacetexture) {     }  };  private void opencamera(int width, int height) {     final activity activity = getactivity();     if (null == activity || activity.isfinishing()) {         return;     }     cameramanager manager = (cameramanager) activity.getsystemservice(context.camera_service);     try {         log.d(tag, "tryacquire");         if (!mcameraopencloselock.tryacquire(2500, timeunit.milliseconds)) {             throw new runtimeexception("time out waiting lock camera opening.");         }         string cameraid = manager.getcameraidlist()[0];          cameracharacteristics characteristics = manager.getcameracharacteristics(cameraid);         streamconfigurationmap map = characteristics                 .get(cameracharacteristics.scaler_stream_configuration_map);         msensororientation = characteristics.get(cameracharacteristics.sensor_orientation);         if (map == null) {             throw new runtimeexception("cannot available preview/video sizes");         }         mvideosize = choosevideosize(map.getoutputsizes(mediarecorder.class));         mpreviewsize = chooseoptimalsize(map.getoutputsizes(surfacetexture.class),                 width, height, mvideosize);          int orientation = getresources().getconfiguration().orientation;         if (orientation == configuration.orientation_landscape) {             mtextureview.setaspectratio(mpreviewsize.getwidth(), mpreviewsize.getheight());         } else {             mtextureview.setaspectratio(mpreviewsize.getheight(), mpreviewsize.getwidth());         }         configuretransform(width, height);         mmediarecorder = new mediarecorder();         manager.opencamera(cameraid, mstatecallback, null); // here crash!!!     } catch (cameraaccessexception e) {         toast.maketext(activity, "cannot access camera.", toast.length_short).show();         activity.finish();     } catch (nullpointerexception e) {         errordialog.newinstance(getstring(r.string.camera_error))                 .show(getchildfragmentmanager(), fragment_dialog);     } catch (interruptedexception e) {         throw new runtimeexception("interrupted while trying lock camera opening.");     } } 

and here how camera permission:

// mainactivity.java private void requestcamerapermission() {     if (activitycompat.shouldshowrequestpermissionrationale(this,             manifest.permission.camera)) {         snackbar.make(mrootview, r.string.permission_camera_rationale,                 snackbar.length_indefinite)                 .setaction(r.string.ok, new view.onclicklistener() {                     @override                     public void onclick(view view) {                         activitycompat.requestpermissions(mainactivity.this,                                 new string[]{manifest.permission.camera, manifest.permission.record_audio}, request_camera);                     }                 })                 .show();     } else {         activitycompat.requestpermissions(this, new string[]{manifest.permission.camera,                 manifest.permission.internet, manifest.permission.record_audio}, request_camera);     } }  @override public void onrequestpermissionsresult(int requestcode, @nonnull string[] permissions, @nonnull int[] grantresults) {     super.onrequestpermissionsresult(requestcode, permissions, grantresults);     if (requestcode == request_camera) {         if (grantresults.length >= 1 && grantresults[0] == packagemanager.permission_granted) {             getsupportfragmentmanager().begintransaction().replace(r.id.content_layout, camera2videofragment.newinstance()).commitallowingstateloss();             //getsupportfragmentmanager().begintransaction().replace(r.id.content_layout, new camerafragment()).commitallowingstateloss();         }     } }
