Enable Airplane Mode on all API levels programmatically Android

android

how to Enable/Disable Airplane Mode programmatically on onClick of a button? i have tried this

// read the airplane mode setting
  boolean isEnabled = Settings.System.getInt(
  getContentResolver(), 
  Settings.System.AIRPLANE_MODE_ON, 0) == 1;

// toggle airplane mode
Settings.System.putInt(
  getContentResolver(),
  Settings.System.AIRPLANE_MODE_ON, isEnabled ? 0 : 1);

// Post an intent to reload
Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
intent.putExtra("state", !isEnabled);
sendBroadcast(intent);

but i get error "System cannot be resolved or is not a field" because it requires API 16 or above

<uses-permission android:name="android.permission.WRITE_SETTINGS"/>

is there any working way of doing so which works on all api levels?
