意外异常：尝试调用虚拟方法'；java.lang.String android.net.Uri.getScheme（）'；关于空对象引用

我正在从Gallery加载图像，并使用

My

onActivityResult

方法代码

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == Activity.RESULT_OK) {

            if (requestCode == CHOOSE_IMAGE) {

                CropImage.activity (data.getData ( ))
                        .setGuidelines (CropImageView.Guidelines.ON)
                        .start (this);

            } else if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
                Uri imageUri = getPickImageResultUri (data);

                // For API >= 23 we need to check specifically that we have permissions to read external storage,
                // but we don't know if we need to for the URI so the simplest is to try open the stream and see if we get error.
                boolean requirePermissions = false;
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M &&
                        checkSelfPermission (Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED &&
                        isUriRequiresPermissions (imageUri)) {

                    // request permissions and handle the result in onRequestPermissionsResult()
                    requirePermissions = true;
                    mCropImageUri = imageUri;
                    requestPermissions (new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 0);
                }


                if (!requirePermissions) {

                }

      mCropImageUri = imageUri;
                try {
                    Bitmap bitmap = MediaStore.Images.Media.getBitmap(getApplicationContext ().getContentResolver() ,  mCropImageUri);

               mCropImageView.setImageBitmap (bitmap);

                } catch (IOException e) {
                    e.printStackTrace ( );
                }
//                mImageLoader.displayImage (String.valueOf (mCropImageUri),mUiCircularImage,options);

            }
        }
    }

一切都很好

resultCode

正常

requestCode

可以

数据

不为空

ImageUri

file:///storage/emulated/0/Android/data/com.hey.heypickup/cache/pickImageResult.jpeg

但是当我想用下面的代码将上面的URI转换成位图时

Bitmap bitmap = MediaStore.Images.Media.getBitmap(getApplicationContext ().getContentResolver() ,  mCropImageUri)

破例

就是这样…

mcropimageri

是

null

特别是，如果此测试为

false

，则问题中没有为其赋值的代码：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M &&
                    checkSelfPermission (Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED &&
                    isUriRequiresPermissions (imageUri))

@juan Cruz的可能副本在我的情况下没有任何内容为空，我正在从Gallery获取图像您可以更新getPickImageResultUri（）和IsUriRequirePermissions（）方法的代码吗？
