【中文标题】权限被拒绝:打开未从 uid 导出的提供程序 com.google.android.apps.photos.contentprovider.MediaContentProvider【英文标题】:Permission denied : opening provider com.google.android.apps.photos.contentprovider.MediaContentProvider that is not exported from uid 【发布时间】:2017-03-19 05:22:27 【问题描述】:当我尝试访问之前存储在 SharedPreferences 中的照片 URI 时,我的应用程序仅在 android >= 6.0 (marshmallow) 中崩溃。虽然第一次检索图像没有任何错误。我正在使用targetSdkVersion
22,因此我不需要在 API >=23 中处理运行时权限。
我的清单文件中的权限
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.CAPTURE_AUDIO_OUTPUT" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.MANAGE_DOCUMENTS" />
我得到的图像如下:
// Determine Uri of camera image to save.
final File root = new File(Environment.getExternalStorageDirectory() + File.separator + "pics" + File.separator);
root.mkdirs();
final String fname = Calendar.getInstance().getTimeInMillis() + ".jpg";
final File sdImageMainDirectory = new File(root, fname);
outputFileUri = Uri.fromFile(sdImageMainDirectory);
// Camera.
final List<Intent> cameraIntents = new ArrayList<Intent>();
final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
final PackageManager packageManager = getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for (ResolveInfo res : listCam)
final String packageName = res.activityInfo.packageName;
final Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
cameraIntents.add(intent);
// Filesystem.
Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
// Chooser of filesystem options.
final Intent chooserIntent = Intent.createChooser(galleryIntent, "Select Source");
// Add the camera options.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[cameraIntents.size()]));
startActivityForResult(chooserIntent, Constants.IMAGE_PICKER);
这是我的 OnActivityResult 方法:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
if (resultCode == RESULT_OK)
if (requestCode == Constants.IMAGE_PICKER)
if (data == null)
selectedImageUri = outputFileUri;
else
selectedImageUri = data.getData();
if (selectedImageUri != null)
try
String path = AppUtils.getPath(this, selectedImageUri);
if (path != null)
Bitmap bitmap = AppUtils.decodeFile(new File(path));
File f = new File(System.currentTimeMillis() + ".jpg");
OutputStream os = new BufferedOutputStream(new FileOutputStream(f));
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, os);
os.close();
uploadImageToServer(f, bitmap);
catch (Exception e)
e.printStackTrace();
其中 getPath() 是来自https://***.com/a/20559418/3758972 的函数。

我不知道我错过了什么。请帮忙。
【问题讨论】:
I try to access a photo URI stored previously in SharedPreferences.
。可以,但您没有发布您在其中放入的方式和内容。你如何提取它以及如何使用它。所以没什么好说的。
你有一个复杂的选择意图。从来没见过这样的。 Intent.EXTRA_INITIAL_INTENTS, cameraIntents.
这个有什么作用?
SharedPreference
部分无关紧要并且工作正常。这会为多个应用创建一个选择器。
在这里发布问题时不要这样做。只需尽可能使用最简单的 ACTION_PICK,然后展示如何将选择的 uri 保存到共享首选项,以及如何直接和之后使用它。您没有发布该代码。这是我第二次要求你这样做。
我使用 ***.com/a/29588566/3758972 解决了我的问题。谢谢。
【参考方案1】:
在您的意图中使用 ACTION_OPEN_DOCUMENT 而不是 ACTION_PICK。它允许对您请求的文件进行长期、持久的访问。
Intent galleryIntent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
这里的文档: https://developer.android.com/guide/topics/providers/document-provider.html
【讨论】:
【参考方案2】:创建一个类名 RealPathUtil,如下所示
import android.annotation.SuppressLint;
import android.content.Context;
import android.content.CursorLoader;
import android.database.Cursor;
import android.net.Uri;
import android.provider.DocumentsContract;
import android.provider.MediaStore;
public class RealPathUtil
@SuppressLint("NewApi")
public static String getRealPathFromURI_API19(Context context, Uri uri)
String filePath = "";
String wholeID = DocumentsContract.getDocumentId(uri);
// Split at colon, use second item in the array
String id = wholeID.split(":")[1];
String[] column = MediaStore.Images.Media.DATA ;
// where id is equal to
String sel = MediaStore.Images.Media._ID + "=?";
Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
column, sel, new String[] id , null);
int columnIndex = cursor.getColumnIndex(column[0]);
if (cursor.moveToFirst())
filePath = cursor.getString(columnIndex);
cursor.close();
return filePath;
@SuppressLint("NewApi")
public static String getRealPathFromURI_API11to18(Context context, Uri contentUri)
String[] proj = MediaStore.Images.Media.DATA ;
String result = null;
CursorLoader cursorLoader = new CursorLoader(
context,
contentUri, proj, null, null, null);
Cursor cursor = cursorLoader.loadInBackground();
if(cursor != null)
int column_index =
cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
result = cursor.getString(column_index);
return result;
public static String getRealPathFromURI_BelowAPI11(Context context, Uri contentUri)
String[] proj = MediaStore.Images.Media.DATA ;
Cursor cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
int column_index
= cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
那么就可以在onActivityResult
中获取Real路径了
String realPath;
// SDK < API11
if (Build.VERSION.SDK_INT < 11)
realPath = RealPathUtil.getRealPathFromURI_BelowAPI11(this, data.getData());
// SDK >= 11 && SDK < 19
else if (Build.VERSION.SDK_INT < 19)
realPath = RealPathUtil.getRealPathFromURI_API11to18(this, data.getData());
// SDK > 19 (Android 4.4)
else
realPath = RealPathUtil.getRealPathFromURI_API19(this, data.getData());
盐:
content://com.android.providers.media.documents/document/image:36
到
/storage/emulated/0/Pictures/JPEG_20190812_163204_299063245992150918.jpg
希望这有帮助!
【讨论】:
是否可以在所有 SDK 版本上简单地使用“SDK 【参考方案3】:改进@Ashton Coulson 的回答,你可以处理Kitkat 版本来使用这个参数:
String action;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT)
action = Intent.ACTION_OPEN_DOCUMENT;
else
action = Intent.ACTION_PICK;
Intent intent = new Intent(action, uri);
需要 if 是因为如 documentation 中所述,Android 4.4(API 级别 19)中引入了存储访问框架 (SAF)。
【讨论】:
【参考方案4】:你应该获得一个持久化的 uri 权限:
Uri uri = intent.getData();
context.getContentResolver().takePersistableUriPermission(uri
, intent.getFlags()
& ( Intent.FLAG_GRANT_READ_URI_PERMISSION
+ Intent.FLAG_GRANT_WRITE_URI_PERMISSION
)
);
【讨论】:
现在我收到了No persistable permission grants found for UID 10389 and Uri 0 @ content://com.google.android.apps.photos.contentprovider/0/1/content://media/external/images/media/41287/ORIGINAL/NONE/1381709033
【参考方案5】:
你可以添加这一行:
intent.addFlags(FLAG_GRANT_READ_URI_PERMISSION); intent.addFlags(FLAG_GRANT_PERSISTABLE_URI_PERMISSION);
【讨论】:
不起作用 - 同样的错误。以上是关于权限被拒绝:打开未从 uid 导出的提供程序 com.google.android.apps.photos.contentprovider.MediaContentProvider的主要内容,如果未能解决你的问题,请参考以下文章
权限拒绝:无法附加文件,文件需要导出提供程序,或 grantUriPermission(),API 29
