Quickly launch the scan application in Q2/Q3

Physical action: double click power button. This feature can quickly launch the scan application. When click, the system will search for all the applications installed in the system and will launch the application with the scan intent-filter. If there are many applications, the system will provide a list for users to choose, and the selected application will start. The code for the scan intent-filter is as follows:

   <action android:name="android.intent.action.SCAN" />
   <category android:name="android.intent.category.DEFAULT" />

When there is no application in the system to define the scan intent-filter, pressing will not work. For example: In order to use the scan button to quickly launch the scan application, the application must define the scan intent-filter in its Android manifest file. The category and the action are defined as follows:

   <activity
   android:name="com.XX.activity.MainActivity"
   android:label="@string/app_name" >
    <intent-filter>      
      <action android:name="android.intent.action.SCAN" />
      <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
   </activity>
