安卓4.0。通话记录 - securityexception

Question

String[] projection = new String[] {
   CallLog.Calls._ID, 
   CallLog.Calls.CACHED_NAME, 
   CallLog.Calls.DATE, 
   CallLog.Calls.DURATION, 
   CallLog.Calls.NUMBER, 
   CallLog.Calls.TYPE 
};

Cursor cursor = this.getContentResolver().query(
       android.provider.CallLog.Calls.CONTENT_URI, projection, null, null, null
);

我想从 android 调用日志中获取我的应用程序的调用日志。目前我一直在研究android 4.0版本。我试过上面的代码，它会产生以下异常。这是什么原因呢？我已经放置了<uses-permission android:name="android.permission.READ_CONTACTS" /> list 文件的权限标记。

Answer 1

如错误跟踪所示:

requires android.permission.READ_CALL_LOG or android.permission.WRITE_CALL_LOG

你还需要添加

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

或

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

到您在 AndroidManifest 中的权限使用列表。

当然，如果您只是阅读，您不应该同时设置 WRITE 权限 - READ 就足够了。
