ImageCapture uri

Question

我正在尝试将捕获的图像的输出转换为uri，但是它会在另一个非空的组件上抛出空指针异常，之前和之后没有将图像存储在uri中它运行正常

Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
                    mImageCaptureUri1 = Uri.fromFile(new File(Environment.getExternalStorageDirectory(),
                            "Photo" + String.valueOf(System.currentTimeMillis()) + ".jpg"));                
                    cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mImageCaptureUri1);                     
                    cameraIntent.putExtra("return-data", true);
                    startActivityForResult(cameraIntent, CAMERA_REQUEST);

和活动结果

protected void onActivityResult(int requestCode, int resultCode, Intent data) {     
        if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {         

            Bitmap temp=null;
            Bundle extras = data.getExtras();
            /*Uri g=data.getData();
                try {
                    temp = MediaStore.Images.Media.getBitmap(getContentResolver(), g);
                } catch (FileNotFoundException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
                } catch (IOException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
                }
             */
            if (extras != null) {               
                Bitmap photo = extras.getParcelable("data");                
                int h=photo.getHeight();
                int w=photo.getWidth();             
                /*   try {

                    temp = MediaStore.Images.Media.getBitmap(this.getContentResolver(), mImageCaptureUri1);
                } catch (FileNotFoundException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
                } catch (IOException e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
                }*/

                try {
                    ByteArrayOutputStream stream = new ByteArrayOutputStream();
                    photo.compress(Bitmap.CompressFormat.PNG, 100, stream);
                    bitmapdata = stream.toByteArray();
                    Log.i("image", ""+bitmapdata);
                    image_boolean=true;
                    stream.flush();
                    stream.close();
                    /*File f = new         File(mImageCaptureUri1.getPath());            
                    if (f.exists()) f.delete();*/

                }catch(Exception e)
                {}
                imageView.setImageBitmap(photo);
            }}

    }
