Android: Camera2 switching between back and front camera -


i working on taking photo camera, , seems good, i'm using camera2basic sample, code offre camera added button switch between 2 cameras :

boolean facingcamera = true; // initialization

onclick() {     facingcamera = !facingcamera;     closecamera();     opencamera(mtextureview.getwidth(), mtextureview.getheight());  }

and changed method setupcameraoutputs code :

if (facing != null && facing == cameracharacteristics.lens_facing_front ) {     continue; }

to

if (facing != null && facing == cameracharacteristics.lens_facing_front && !facingcamera  || facing != null && facing == cameracharacteristics.lens_facing_back && facingcamera ) {     continue; }

this work fine nexus 4 lg-d802 not working fine ( onconfigurefailed called each time try change camera )

how fix work fine on devices?

did check if cameramanager giving 2 available cameras? use cameramanager.getcameraidlist() check it. remember right preview sizes each camera using cameracharacteristics:

streamconfigurationmap rearmap = rearcameracharacteristics.get(       cameracharacteristics.scaler_stream_configuration_map); streamconfigurationmap frontmap = frontcameracharacteristics.get(       cameracharacteristics.scaler_stream_configuration_map);

after use 1 of values initialize preview, if using same value front , camera maybe having problems cause front camera don't support resolution size.
