Code to enable accessibility services
The defined AccessibilityService is disabled by default and needs to be manually enabled or automatically enabled on the accessibility interface.
There are currently two ways to automatically start the service. It is necessary to modify the source code or configure the application as a system application.
1. Modify
frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java in the source code
and add the following code in the loadSecureSettings function:
loadSetting(stmt, Settings.Secure.ACCESSIBILITY_ENABLED, 1);
loadSetting(stmt , Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES,"your defined service");
The format of "your defined service": com.125la.main/com.125la.service.MyAccessibilityService
2. System application and compile in the system
Declare permission requirements in AndroidManiferst.xml
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />
Add at the APP startup entry:
Settings.Secure.putString(getContentResolver(),Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES,"你定义的服务");
Settings.Secure.putInt(getContentResolver(),Settings.Secure.ACCESSIBILITY_ENABLED, 1);
The format to fill in the "service you define": pkgname/classname
1 means on, 0 means off
Turn off accessibility code
Settings.Secure.putString(getContentResolver(),Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES,"");
Settings.Secure.putString(getContentResolver(),Settings.Secure.ACCESSIBILITY_ENABLED, 0);
3. Summary:
I have tried two methods, and the second method has some minor problems, such as the inability to monitor after burning the system for the first time and after restoring the factory settings, but it is possible in other cases.
