What I'm trying to do is turn off a BroadcastReceiver when X time passes. This I already achieve, and it works. I tried it using a switch and it worked, when it was in on . It was activated and when it was in off no. Initially I have it disabled, my goal is that when it happens for a while X is activated. I also checked that I entered the run() method using the Log.d() and entered. The problem is when I call the method, also try to copy the method activarFuncion() for the class Timer, but it tells me that cannotresolve getPackageManager() , in order that it does not work. The class Call_Reciver is the one that inherits from BroadcastReceiver . Any ideas???
Here is the COMPLETE class (only the import ones are missing):
public class Activity_llamadas extends Activity {
Button boton;
EditText editText;
TextView textView;

TextView textView3;

int h=0,m=0;

@Override
public void onCreate(Bundle savedInstanceState) {
ComponentName reciver= new ComponentName(this,Call_Reciver.class);
PackageManager pm=getPackageManager();
pm.setComponentEnabledSetting(reciver,PackageManager.COMPONENT_ENABLED_STATE_DISABLED,PackageManager.DONT_KILL_APP);
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_llamadas);
aSwitch= (Switch)findViewById(R.id.switchAcvivar);
SimpleDateFormat date= new SimpleDateFormat("mm");
String mhora= date.format(System.currentTimeMillis());
textView3=(TextView)findViewById(R.id.textHoraAct);
textView3.setText(mhora);
vivatror = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);

}
});

Method in the class
MainActivity:
public void activarFuncion(){
ComponentName reciver= new ComponentName(this,Call_Reciver.class);
PackageManager pm=getPackageManager();
pm.setComponentEnabledSetting(reciver,PackageManager.COMPONENT_ENABLED_STATE_ENABLED,PackageManager.DONT_KILL_APP);
}
Timer Class:
public class Temporizador extends TimerTask {
Activity_llamadas activity_llamadas;
@Override
public void run(){
activity_llamadas.activarFuncion();//<----------ESTA ES LA LINEA 15
}
}
