title: Accessibility force enabling is not working in android jelly bean
body: <p>My project need accessibility feature, I need to enable programmatically. I am using below code snippet to make on.</p>
  
  <pre><code>Settings.Secure.putString(context.getContentResolver(), 
                  Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES, 
              appInfo);
  
          Settings.Secure.putString(context.getContentResolver(), 
                  Settings.Secure.ACCESSIBILITY_ENABLED, 
                  "1");
  
          Settings.Secure.putString(context.getContentResolver(),
                                    Settings.Secure.TOUCH_EXPLORATION_ENABLED,
                                    "1");
  
  Settings.Secure.putString(context.getContentResolver(),
                                          "touch_exploration_granted_accessibility_services",
                                    appInfo);
  </code></pre>
  
  <p>But it is not working does in a android device where 5.1 OS is available.
  In lower versions it works as expected.
  any changes in api after 4.0?</p>
