所以我加入com.google.android.gallery3d.permission.GALLERY_PROVIDER了我的清单,但我仍然遇到了这个错误,所以我还需要做什么？这是我第一次看到这个,并且没有在网上找到有关此问题的信息.

如果这将是一个问题,我可以让画廊显示设备和exclude Picasa图像上的图像吗？

就像我说我之前没有4.2遇到过这个问题,也许它与a有关recent google+ update?

编辑:

在我离开应用程序并尝试再次启动它之后,它只会给我错误.因此,如果我在应用程序中并选择图像以显示它第一次正常工作,直到我退出.我存储Uri在我的数据库中以在启动时加载

这是我的清单权限

我最终解决这个问题的方法是将图像保存在本地，并在需要图像时使用该图像的 uri

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent){
        super.onActivityResult(requestCode, resultCode, imageReturnedIntent); 

            if(resultCode == Activity.RESULT_OK && requestCode == 1){  
                Uri selectedImage = imageReturnedIntent.getData();
                new SaveImage().execute(selectedImage.toString());

        }
    }

public class SaveImage extends AsyncTask<String,Void,Void>{

        @Override
        protected Void doInBackground(String... params) {
            String uri = params[0];

            if(uri != null && !uri.equals("")){
                ContextWrapper cw = new ContextWrapper(getActivity());
                File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
                File mypath=new File(directory,String.valueOf(bowlerID)+"profile.jpg");
                FileOutputStream fos = null;
                InputStream input = null;
                try { 
                    fos = new FileOutputStream(mypath);
                    input = getActivity().getContentResolver().openInputStream(Uri.parse(uri));
                    Bitmap bitmap = BitmapFactory.decodeStream(input);
                    if(bitmap != null){
                        if(bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos)){
                            ContentValues values = new ContentValues();
                            values.put(BowlersDB.PHOTO_URI, mypath.getAbsolutePath());
                            getActivity().getContentResolver().update(BowlersDB.CONTENT_URI, values,BowlersDB.ID+"="+bowlerID,null);
                        }
                    }
                    fos.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
            return null;
        }

    }
