java.lang.UnsupportedOperationException

刚才在使用事务添加联系人时，报了如下的错误信息：

java.lang.UnsupportedOperationException: Aggregate contacts are created automatically

另外testAddContactsByTransaction() 方法进行单元测试时，报了如下的错误消息：

java.lang.UnsupportedOperationException: URI: content://com.android.contacts/raw_contants, calling user: cn.jbit.Contact, calling package:cn.jbit.Contact

当时，单元测试的方法如下：

/***

* 利用事务添加 联系人 毕竟 添加的时候 是在多张表中进行添加的

* @throws Exception

* @throws RemoteException

*/

public void testAddContactsByTransaction() throws RemoteException, Exception{

ContentResolver rs =this.getContext().getContentResolver();

ArrayList<ContentProviderOperation> operations =new ArrayList<ContentProviderOperation>();

Uri uri =Uri.parse("content://com.android.contacts/raw_contants");

ContentProviderOperation op1 =ContentProviderOperation.newInsert(uri)

.withValue("account_name", null)

.build();

operations.add(op1);

Uri uri2 =Uri.parse("content://com.android.contacts/data");

ContentProviderOperation op2 =ContentProviderOperation.newInsert(uri2)

.withValueBackReference("raw_contact_id", 0) // 这里相当于 为其指定了 where 条件 当条件有多个时 就使用ContentValues

.withValue("mimetype", "vnd.android.cursor.item/name")

.withValue("data1", "张三")

.build();

operations.add(op2);

ContentProviderOperation op3 =ContentProviderOperation.newInsert(uri2)

.withValueBackReference("raw_contact_id", 0)

.withValue("mimetype", "vnd.android.cursor.item/phone_v2")

.withValue("data1", "12345678")

.build();

operations.add(op3);

ContentProviderOperation op4 =ContentProviderOperation.newInsert(uri2)

.withValueBackReference("raw_contact_id", 0)

.withValue("mimetype", "vnd.android.cursor.item/email_v2")

.withValue("data1", "zhjw009@163.com")

.build();

operations.add(op4);

rs.applyBatch("com.android.contacts", operations); // 该方法的内部结构 会 循环 提供的这些 内容提供者操作对象 并按事务的方式处理

}

当你仔细看有对应颜色匹配的代码和错误消息，不难发现：

当程序抛出 java.lang.UnsupportedOperationException异常时，基本上可以猜测是 Uri 写错了；
