Android 相机意图不返回/锁定

Question

I'm trying to take a picture from the Camera using intent with onActivityResult but every time I take a picture the camera locks up and never returns. Any reason why this might happen? This is the code I'm using:

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST); 

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    Log.v(TAG,"Camera callback: "+Integer.toString(resultCode));
    if (requestCode == CAMERA_PIC_REQUEST) {
        try{
            Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
            Log.v("Picture view",data.getData().toString());
            ImageView image = new ImageView(this);
            image.setImageBitmap(thumbnail);  
            setContentView(image);
        }
        catch(Exception e){
            Log.e(TAG, "something happened");
            e.printStackTrace();
        }

    }
}

This is the LogCat output after taking a picture:

06-12 19:46:03.881: VERBOSE/camera(443): Start autofocus.
06-12 19:46:04.521: VERBOSE/camera(443): doSnap: mFocusState=1
06-12 19:46:04.721: VERBOSE/camera(443): mAutoFocusTime = 790ms

Then it just locks up and onActivityResult never fires.

Thanks for your inputs.

I read a bunch of tutorials and everyone does it different. The official Android Docs use the Camera -class (step by step tutorial on the linked page).

I found this other tutorial (which uses the MediaStore -class, like you), but put an extra for the Output-File on the Intent.

You might want to check both of this tutorials and see if one works for you.
