试图从Android Contacts URI中读取java.lang.SecurityException

我正在尝试从ContactsContract URI中读取联系人姓名,电话号码和电子邮件,当我尝试运行该程序时,我收到一个SecurityException.我已经在 AndroidManifest.xml文件中设置了权限：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="edu.smumn.cs394"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-sdk android:minSdkVersion="8" />
    **<uses-permission android:name="android.pemission.READ_CONTACTS"/>**
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".ReadPhoneNumbers"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>`

以下是应用代码：

@Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.contact_list);       
        ContentResolver resolver = getContentResolver();
        Cursor c = resolver.query(ContactsContract.Contacts.CONTENT_URI,null,null);
 //[...] Work through data here`

我在最后一行得到一个安全例外(resolver.query())：

`03-08 07:41:40.812: ERROR/AndroidRuntime(416): FATAL EXCEPTION: main
03-08 07:41:40.812: ERROR/AndroidRuntime(416): java.lang.RuntimeException: Unable to start activity ComponentInfo{edu.smumn.cs394/edu.smumn.cs394.ReadPhoneNumbers}: java.lang.SecurityException: Permission Denial: reading com.android.providers.contacts.ContactsProvider2 uri content://com.android.contacts/contacts from pid=416,uid=10037 requires android.permission.READ_CONTACTS

我一定是错过了一些东西,但是我无法弄明白什么.

解决方法

确保将其添加到应用程序标签之外.当在Ubuntu上使用Eclipse开发2.3.3的目标平台时,我在日志文件中出现了许可失败,表明我在类似的工作中需要这个精确的行.直到我将* uses-permission … READ_CONTACTS *行移动到应用程序标签之外才有效.
