在app里面需要做以下设置（一般是在manifest.xml文件的activity的 intent filter里面）
<span style="font-size:18px;"><intent-filter> <action android:name="android.intent.action.VIEW" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" /> <data android:scheme="**" //scheme name ‘TencentQQ‘ android:host="**.**" android:pathPrefix="/**"> </data> </intent-filter></span>
