Android development implements methods to determine whether the notification bar is open and go to the settings page

This article describes the method of Android development to determine whether the notification bar is open and go to the settings page. Share it for your reference, as follows:

The schedule reminder function is used in the project. If the application's notification bar is not opened, the user needs to be prompted to open the notification bar and determine whether the notification bar is open as follows:

private boolean isNotificationEnabled(Context context) {
    String CHECK_OP_NO_THROW = "checkOpNoThrow";
    String OP_POST_NOTIFICATION = "OP_POST_NOTIFICATION";
    AppOpsManager mAppOps = (AppOpsManager) (Context.APP_OPS_SERVICE);
    ApplicationInfo appInfo = ();
    String pkg = ().getPackageName();
    int uid = ;
    Class appOpsClass = null;
   /* Context.APP_OPS_MANAGER */
    try {
      appOpsClass = (());
      Method checkOpNoThrowMethod = (CHECK_OP_NO_THROW, , ,
          );
      Field opPostNotificationValue = (OP_POST_NOTIFICATION);
      int value = (Integer) ();
      return ((Integer) (mAppOps, value, uid, pkg) == AppOpsManager.MODE_ALLOWED);
    } catch (ClassNotFoundException e) {
      ();
    } catch (NoSuchMethodException e) {
      ();
    } catch (NoSuchFieldException e) {
      ();
    } catch (InvocationTargetException e) {
      ();
    } catch (IllegalAccessException e) {
      ();
    }
    return false;
}

When the return value is true, the notification bar is open and false is not open.

The following code is to go to the settings page:

private void goToSet(){
    if (.SDK_INT &gt;= Build.VERSION_CODES.BASE) {
      // Enter the system application permission interface      Intent intent = new Intent(Settings.ACTION_SETTINGS);
      startActivity(intent);
      return;
    } else if (.SDK_INT &gt;= Build.VERSION_CODES.LOLLIPOP) {// Use the running system in the environment      // Enter the system application permission interface      Intent intent = new Intent(Settings.ACTION_SETTINGS);
      startActivity(intent);
      return;
    }
}

Note: When testing the function, it was found that if the app's notification bar is turned off in the application settings/display notifications are not checked, Toast cannot display it.
