Question

这是一个扩展basecolumns的类

public static final String AUTHORITY = "imammuda";
public static final String PROGRAMPATH = "Program";

public static final Uri PROGRAM_URI = Uri.parse("content://" + AUTHORITY + "/" + PROGRAMPATH);

这是扩展contentprovider

的contentProvider类

static{
    sUriMatcher.addURI(ImamShareData.AUTHORITY, ImamShareData.PROGRAMPATH, PROGRAM);
    sUriMatcher.addURI(ImamShareData.AUTHORITY, ImamShareData.PROGRAMPATH + "/#", PROGRAM_ID);
}
@Override
public Uri insert(Uri uri, ContentValues initialvalues) {
    TableNumber = sUriMatcher.match(uri);
    if( TableNumber != PROGRAM){
        throw new IllegalArgumentException("Unknown URI " + uri);
    }
}

这是一个扩展expandablelist活动的类

private void createdata(){
(...)
(...)
    for(int i = 0; i < title.length; i++){
        ContentValues values = new ContentValues();
        values.put(ImamShareData.DataContent.KEY_PROGRAM_TITLE, title[i]);
        Uri group = cr.insert(ImamShareData.DataContent.PROGRAM_URI, values); <== when call give error
    }

这是清单xml

<provider android:authorities="imammuda" android:name="contentProvider" android:multiprocess="true"></provider>

这是logcat

在AndroidManifest文件中，提到android：name元素下的完整包名称。尝试使用权限作为包名。
