Then configure AndroidManifest;
In application AndroidManifest.xml Add configured <application> Add the following configurations under the node （ notes ： Failure to configure will result in failure to call API）;

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<application>

<application>

Then initialize SDK

3.5.7 The new version interface provides the user with the ability to set whether the user is authorized to obtain the device information , Calling interconnection SDK Before relevant functional interfaces , The application needs to confirm that the user has authorized the application to obtain the device information , Call the following code to notify SDK：

Tencent.setIsPermissionGranted(true);

If the interface is not called or the parameter is false when , Calling other function interfaces will directly return failure .
