i need set control_scene_mode_action app camera2api.

i tryed set capturestillpicture() method in lockfocus() method in statecallback doesn't work...

in documentation found explanation is, lines how mode have set up...

there 2 question:

  1. where exacly have set mode
  2. how can check working

or maybe can suggest me how reduse expose time...

thanks in advance

you can modify camera2basicfragment google camera2basic sample add line

mpreviewrequestbuilder.set(capturerequest.control_scene_mode, capturerequest.control_scene_mode_action);

just after line

mpreviewrequestbuilder.set(capturerequest.control_af_mode, capturerequest.control_af_mode_continuous_picture);

in onconfigured() method of example

@override public void onconfigured(@nonnull cameracapturesession cameracapturesession) {     // camera closed     if (null == mcameradevice) {         return;     }      // when session ready, start displaying preview.     mcapturesession = cameracapturesession;     try {         // auto focus should continuous camera preview.         mpreviewrequestbuilder.set(capturerequest.control_af_mode,                 capturerequest.control_af_mode_continuous_picture);         mpreviewrequestbuilder.set(capturerequest.control_scene_mode,                 capturerequest.control_scene_mode_action);         // flash automatically enabled when necessary.         setautoflash(mpreviewrequestbuilder);          // finally, start displaying camera preview.         mpreviewrequest = mpreviewrequestbuilder.build();         mcapturesession.setrepeatingrequest(mpreviewrequest,                 mcapturecallback, mbackgroundhandler);     } catch (cameraaccessexception e) {         e.printstacktrace();     } }
