Add my app to AutoStart apps list in android programmatically

Some of the applications such as Whatsapp and Facebook might have been whiltlisted thats why they have automatic Autostart option enabled.

But i have tried the following code for Xiaomi Devices hope this might help!!

    String manufacturer = "xiaomi";
    if(manufacturer.equalsIgnoreCase(android.os.Build.MANUFACTURER)) {
        //this will open auto start screen where user can enable permission for your app
        Intent intent = new Intent();
        intent.setComponent(new ComponentName("com.miui.securitycenter", "com.miui.permcenter.autostart.AutoStartManagementActivity"));
        startActivity(intent);
    }

Few popular apps run in background without being killed during memory cleanup cycle (many of the popular OEMs customize the stack ROM for battery/memory optimization), because they are "White listed" by these manufactures. For your app you can whitelist it either manually (via corresponding "settings" for the devices) or pragmatically by redirecting users to the corresponding settings page to white list the app.

Please have a look for details here
