Androidda xizmat bilan internet aloqasi tekshirilmoqda

Translyatsiya qabul qiluvchisidan foydalanishingiz kerak bo'lishi mumkin. Siz doimiy ravishda ulanish bo'yicha yangilanishlarni olasiz. (Ulangan/O'chirilgan)

Misol:

Manifest:

Ruxsatlar:

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

Translyatsiya qabul qiluvchini ro'yxatdan o'tkazing:

<receiver android:name=".ConnectivityChangeReceiver" >
    <intent-filter>
        <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />
    </intent-filter>
</receiver>

Qabul qiluvchilar sinfini yarating:

public class ConnectivityChangeReceiver extends BroadcastReceiver {


    @Override
    public void onReceive(Context context, Intent intent) {

        // Explicitly specify that which service class will handle the intent.
        ComponentName comp = new ComponentName(context.getPackageName(),
                YourService.class.getName());
        intent.putExtra("isNetworkConnected",isConnected(context));
        startService(context, (intent.setComponent(comp)));
    }

 public  boolean isConnected(Context context) {
           ConnectivityManager connectivityManager = ((ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE));
           NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
           return networkInfo != null && networkInfo.isAvailable() && networkInfo.isConnected();
   }

}

Xizmat sinfingiz:

class YourService extends IntentService{

    @Override
    protected void onHandleIntent(Intent intent) {
      Bundle extras = intent.getExtras();
      boolean isNetworkConnected = extras.getBoolean("isNetworkConnected");
      // your code

   }

}

Tizim tarmoq ulanishi oʻzgarganda Broadcast beradi, uni BroadcastReceiver< orqali oʻqishingiz mumkin. /a>. Bu sizning ilovangiz ochiq yoki yopiq bo'lishidan qat'i nazar, chaqiriladi.

Quyidagi koddan foydalanib, qurilma internetga ulangan yoki yo'qligini tekshirishingiz mumkin. Bu funksiyadan istalgan vaqtda istalgan veb-xizmat yoki internet bilan bog'liq har qanday vazifaga qo'ng'iroq qilishga urinayotganingizda foydalanishingiz mumkin. Bu funksiyadan fonda ishlaydigan android xizmatida foydalanishingiz mumkin.

public boolean isConnectingToInternet(Context _context){
        ConnectivityManager connectivity = (ConnectivityManager) _context.getSystemService(Context.CONNECTIVITY_SERVICE);
          if (connectivity != null)
          {
              NetworkInfo[] info = connectivity.getAllNetworkInfo();
              if (info != null)
                  for (int i = 0; i < info.length; i++)
                      if (info[i].getState() == NetworkInfo.State.CONNECTED)
                      {
                          return true;
                      }

          }
          return false;
    }
