这是code用于获取的ImagePath ..

this is the code for getting the Imagepath..

    Uri originalUri = data.getData();

            final int takeFlags = data.getFlags()
                                & (Intent.FLAG_GRANT_READ_URI_PERMISSION
                                | Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
            // Check for the freshest data.
            getContentResolver().takePersistableUriPermission(originalUri, takeFlags);

            String id = originalUri.getLastPathSegment().split(":")[1]; 
            final String[] imageColumns = {MediaStore.Images.Media.DATA };
            final String imageOrderBy = null;

            Uri uri = getUri();

            @SuppressWarnings("deprecation")
            Cursor imageCursor = managedQuery(uri, imageColumns,
                  MediaStore.Images.Media._ID + "="+id, null, imageOrderBy);

            if (imageCursor.moveToFirst())
            {
                picturepath = imageCursor.getString(imageCursor.getColumnIndex(MediaStore.Images.Media.DATA));
            }
            Bitmap b=decodeSampledBitmapFromFile(picturepath, 175, 175);
            imgToBeUploaded.setImageBitmap(b);
            Toast.makeText(StartingActivity.this, picturepath, Toast.LENGTH_SHORT).show();

感谢和问候。

推荐答案

最有可能你正在因为该行的java.lang.SecurityException异常

Most probably you are getting java.lang.SecurityException because of this line

getContentResolver().takePersistableUriPermission(originalUri, takeFlags);

试图捕获异常，并应工作。

try to catch exception and should work.
