android调用系统相机

Intent intent = new Intent();
                intent.setPackage("com.android.camera");
                intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent, 1);

                Intent intent = new Intent();
                intent.setPackage("com.android.camera");
//                intent.setAction(MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent, 1);

Intent imageCaptureIntent = new Intent("android.media.action.STILL_IMAGE_CAMERA");
               startActivityForResult(imageCaptureIntent,1);

包名+主类名才是王道。
