android mediastore指定前置摄像头,Intent方式打开前置摄像头

已经失效的方法

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

if (front) {

intent.putExtra("android.intent.extras.CAMERA_FACING", 1);

}

intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(targetFile));

startActivityForResult(this, intent, requestCode);

正确打开前置摄像头的姿势

Intent intent;

if (front) {

intent = new Intent(MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA);

intent.putExtra("android.intent.extras.CAMERA_FACING", android.hardware.Camera.CameraInfo.CAMERA_FACING_FRONT);

intent.putExtra("android.intent.extras.LENS_FACING_FRONT", 1);

intent.putExtra("android.intent.extra.USE_FRONT_CAMERA", true);

} else{

intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

}

intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(targetFile));

startActivityForResult(this, intent, requestCode);

关键在于需要使用MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA
