Question

将program1复制到paste2程序

的AndroidManifest.xml：

程序1：

<provider android:name="com.coperator.service.PreferenceProvider"
                    android:authorities="com.coperator.prefs" />

program2：

<provider android:name="com.coperator.service.PreferenceProvider"
                    android:authorities="com.program2.coperator.prefs" />

java代码：

  program1: public static final String AUTHORITY= "com.coperator.prefs";
  program2: public static final String AUTHORITY = "com.program2.coperator.prefs";

  public static final Uri RAZ_URI = Uri.parse(ContentResolver.SCHEME_CONTENT+ "://" +           AUTHORITY + "/" + RESET_TABLE_NAME);     
  Uri uri = SipConfigManager.RAZ_URI;
  resolver.update(uri, new ContentValues(), null, null);

首先运行program1 normal，运行program2时出错：

我不知道这是怎么回事

Answer 1

在我的应用开发期间，我遇到了同样的错误。对我来说，在调用Content Provider时使用正确的Uri解决了错误。

在我的内容提供商中，我添加了一些Uri，例如：

String AUTHORITY = "com.package.example";
static Uri CONTENT_URI = Uri.parse(AUTHORITY);

(...)

URIMatcher.addURI(AUTHORITY, "entry", 1);

之后，在调用ContentProvider时，我做了

getContentResolver().getType(Uri.withAppendedPath(MyContentProvider.CONTENT_URI, "entry/1"));

这个问题没有再发生。

无法找到com.talkingoa.coperator.prefs的提供商信息
