复制原项目program1为program2
AndroidManifest.xml中：
program1：<provider android:name="com.coperator.service.PreferenceProvider"
android:authorities="com.coperator.prefs" />
program2: <provider android:name="com.coperator.service.PreferenceProvider"
android:authorities="com.talkingoa.coperator.prefs" />
Java Code如下：
program1: public static final String AUTHORITY= "com.coperator.prefs";
program2: public static final String AUTHORITY = "com.talkingoa.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);
先启动program1正常，启动program2后出现如下错误：
