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.
