尝试获取 Contracts Group 时

Uri contacts = ContactsContract.AUTHORITY_URI;
  //Log.v("23",contacts.toString());
  // Make the query.
  Cursor managedCursor = act.managedQuery(contacts, projection, // Which
    // columns
    // to
    // return
    null, // Which rows to return (all rows)
    null // Selection arguments (none)
    // Put the results in ascending order by name
    , ContactsContract.Groups.TITLE + " ASC"
    );

出现问题：

<uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>
<uses-permission android:name="android.permission.WRITE_CONTACTS"></uses-permission>

我明白错误/DatabaseUtils（198）：java.lang.IllegalArgumentException：未知的URL内容：//com.android.contacts

Problem when trying to get Contracts Group

Uri contacts = ContactsContract.AUTHORITY_URI;
  //Log.v("23",contacts.toString());
  // Make the query.
  Cursor managedCursor = act.managedQuery(contacts, projection, // Which
    // columns
    // to
    // return
    null, // Which rows to return (all rows)
    null // Selection arguments (none)
    // Put the results in ascending order by name
    , ContactsContract.Groups.TITLE + " ASC"
    );

Having:

<uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>
<uses-permission android:name="android.permission.WRITE_CONTACTS"></uses-permission>

I get
ERROR/DatabaseUtils(198): java.lang.IllegalArgumentException: Unknown URL content://com.android.contacts

您使用了错误的 Uri 尝试 ContactsContract.Groups.CONTENT_URI 从我的角度来看，使用联系人组非常棘手，因此请仔细阅读文档

是的，URI 错误。下面是一个按名称查找的示例（来自 http://www.androidref.com/#MapLocation ）：

//
//  Find contact based on name.
//
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
    "DISPLAY_NAME = '" + NAME + "'", null, null);
if (cursor.moveToFirst()) {
    String contactId =
        cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
...

Yes, wrong URI. Here's an example to find by name (from http://www.androidref.com/#MapLocation):

//
//  Find contact based on name.
//
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
    "DISPLAY_NAME = '" + NAME + "'", null, null);
if (cursor.moveToFirst()) {
    String contactId =
        cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
...
