the onReceive method isn't called for some reason
I've not applied any filters or anything,
Here is the class :
import java.util.ArrayList;
import java.util.Calendar;
import android.content.BroadcastReceiver;
import android.content.Intent;
import android.content.Context;
import android.util.Log;
public class RegisterListener extends BroadcastReceiver {
private final int DELAY_TIME = 5;
private int m_seconds = 0;
private int m_minutes = 0;
private int m_hours = 0;
static ArrayList<BroadcastReceiverListener> listeners = new ArrayList<BroadcastReceiverListener>();
@Override
public void onReceive(Context context, Intent intent) {
Log.d("ScreenReceiver Action:",intent.getAction());
Calendar c = Calendar.getInstance();
m_seconds = c.get(Calendar.SECOND);
m_minutes = c.get(Calendar.MINUTE);
m_hours = c.get(Calendar.HOUR);
for (BroadcastReceiverListener listener:listeners){
listener.onReceive(m_hours, m_minutes, m_seconds);
}
}
public static void addBroadcastReceiveListener (BroadcastReceiverListener listener){
if(!listeners.contains(listener)){
listeners.add(listener);
}
}
public void removeBroadcastReceiveListener (BroadcastReceiverListener listener){
if(listeners.contains(listener)){
listeners.remove(listener);
}
}
Here is the declaration in the manifest (child of Application)
<receiver android:name=".RegisterListener"></receiver>
Edit : This is the filter i tried to add (inside the onReceive() )
IntentFilter filter = new IntentFilter(Intent.ACTION_USER_PRESENT);
BroadcastReceiver mReceiver = new RegisterListener();
registerReceiver(mReceiver, filter);
I get an error :
The method registerReceiver(BroadcastReceiver, IntentFilter) is undefined for the type RegisterListener
If you always want to listen for ACTION_USER_PRESENT
, try:
<receiver android:name=".RegisterListener">
<intent-filter>
<action android:name="android.intent.action.USER_PRESENT" />
</intent-filter>
</receiver>
Explanations
The method registerReceiver(BroadcastReceiver, IntentFilter) is undefined for the type RegisterListener
You must use registerReceiver()
with a Context, for example context.registerReceiver(...)
. But:
This is the filter i tried to add (inside the onReceive() )
It doesn't make sense to register a receiver inside onReceive()
because onReceive()
will not run until you have registered a receiver... So it will never happen. You can put this code in onCreate()
in your Activity, like this:
IntentFilter filter = new IntentFilter(Intent.ACTION_USER_PRESENT);
BroadcastReceiver mReceiver = new RegisterListener();
registerReceiver(mReceiver, filter);
This will only listen for ACTION_USER_PRESENT
while your app is already running.
