데이터 최적화 모드 제외

데이터 최적화 모드 제외 설정도 적용 하려고 했으나, 데이터 최적화 모드가 아니면 현재 설정여부를 알 수 없는것 같아서 제외함.

ConnectivityManager connMgr = (ConnectivityManager)
        getSystemService(Context.CONNECTIVITY_SERVICE);
// Checks if the device is on a metered network
if (connMgr.isActiveNetworkMetered()) {
  // Checks user’s Data Saver settings.
  switch (connMgr.getRestrictBackgroundStatus()) {
    case RESTRICT_BACKGROUND_STATUS_ENABLED:
    // Background data usage is blocked for this app. Wherever possible,
    // the app should also use less data in the foreground.

    case RESTRICT_BACKGROUND_STATUS_WHITELISTED:
    // The app is whitelisted. Wherever possible,
    // the app should use less data in the foreground and background.

    case RESTRICT_BACKGROUND_STATUS_DISABLED:
    // Data Saver is disabled. Since the device is connected to a
    // metered network, the app should use less data wherever possible.
  }
} else {
  // The device is not on a metered network.
  // Use data as required to perform syncs, downloads, and updates.
}

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
