Question

我尝试裁剪图像，有时它的工作完美但是大多数时候我在onActivityResult上得到了null值并在日志中显示以下错误以及如何解决这个问题，请帮助我。

这是调用裁剪意图的代码

Intent intent = new Intent("com.android.camera.action.CROP");
Uri myUri = Uri.fromFile(mFileTemp);  // mFileTemp this is the image file name 
intent.setDataAndType(myUri, "image/*");
intent.putExtra("outputX", 100);
intent.putExtra("outputY", 100);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("scale", true);
intent.putExtra("crop", "true");
intent.putExtra("return-data", true);
startActivityForResult(intent, CROP_FROM_CAMERA)

onActivityResult代码：

case CROP_FROM_CAMERA:
           try {
               if (data != null) {
                   Bundle extras = data.getExtras();
                   if (extras != null) {
                      Bitmap photo = extras.getParcelable("data");
                      imageView.setImageBitmap(photo);
                   }
               }
           } catch (Exception e) {

           }
           break;
       }
