How can I start the Accessibility Settings Page of my APP in Android?

You can manually open the accessibility settings with the following Intent (when android.content.Intent and android.app.Intent have both been imported):

Intent intent = new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS);startActivity(intent);

Check out the following resources for more information:

• https://android.googlesource.com/platform/development/+/master/samples/ApiDemos/src/com/example/android/apis/accessibility/ClockBackActivity.java
• http://developer.android.com/reference/android/app/Activity.html

Try this:

Intent intent = new Intent(Settings.ACTION_ACCESSIBILITY_SETTINGS);intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);startActivity(intent);

Maybe the code below can help you :

Intent intent = new Intent();        intent.setClassName("com.android.settings",                "com.android.settings.Settings");        intent.setAction(Intent.ACTION_MAIN);        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK                | Intent.FLAG_ACTIVITY_CLEAR_TASK                | Intent.FLAG_ACTIVITY_EXCLUDE_FROM_RECENTS);        intent.putExtra(PreferenceActivity.EXTRA_SHOW_FRAGMENT,                "the fragment which you want show");        intent.putExtra(PreferenceActivity.EXTRA_SHOW_FRAGMENT_ARGUMENTS,                extras);       startActivity(intent);
