I have an application that runs in the background. As soon as the user opens the application, a service is started to record the calls and send them to a certain folder.

Today, the service identifies the call and records, but the audio sometimes misses in the show. I've noticed that if I open the app and make a call, it will register properly, but if I close the application or if it stays open for more than 5 minutes, the l & # 39; registration will be without broadcast.

Follow my code:

package com.example.call;

public class BroadcastSistemas extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        try {
            String estado = intent.getStringExtra("state");
            String num = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
            String msg = null;

            if (estado.equals("RINGING")) {
                msg = "O número " + num + " está chamando.";
            } else if (estado.equals("OFFHOOK")) {
                msg = "Em ligação.";
            } else if (estado.equals("IDLE")) {
                msg = "O número " + num + " desligou.";
            }

            Toast.makeText(context, msg, Toast.LENGTH_LONG).show();
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
    }
}
