在manifest 文件中已经添加了user-permission 
<uses-permission android:name="android.permission.WRITE_CONTACTS"></uses-permission>    <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>

这时，应该考虑的是android机制的问题，可以看看（Requesting Permissions at Run Time）

错误提示的意思是：需要用户自己去添加对contacts 的授权，而不是让系统给授权，这都是android 6.0及以上的设备上才出现的问题，google 主要是处于安全的考虑，才添加的机制；

解决的方法是：弹出授权提示框，提醒用户授权；

代码如下：

 if (ActivityCompat.checkSelfPermission(this, mPermission[0])                != MockPackageManager.PERMISSION_GRANTED ||                ActivityCompat.checkSelfPermission(this, mPermission[1])                        != MockPackageManager.PERMISSION_GRANTED                )
//授权（如果没有授权，就弹出提示，让用户授权）            ActivityCompat.requestPermissions(this,                    mPermission, REQUEST_CONTACTS);
希望对你有帮助；
