これを試すと、最初のアクティビティで2番目のアクティビティでstartServiceを呼び出します。
startService(新しいインテント(this、NotificationService.class));
以下からなるNotificationService.java作成:
package com.sample;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Timer;
import java.util.TimerTask;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.IBinder;
import android.preference.PreferenceManager;
import android.util.Log;
import android.widget.Toast;
public class NotificationService extends Service
{
private final int UPDATE_INTERVAL = 10 * 1000;
private Timer timer = new Timer();
private static final int NOTIFICATION_EX = 1;
private static final String TAG = "NotificationService";
private NotificationManager notificationManager;
ArrayList<HashMap<String, String>> currentForecast = new ArrayList<HashMap<String, String>>();
CharSequence tickerText="notifi";
public NotificationService(){}
public IBinder onBind1(Intent intent) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
//code to execute when the service is first created
}
@Override
public void onDestroy() {
if (timer != null){
timer.cancel();
}
}
@Override
public int onStartCommand(final Intent intent, final int flags, final int startid) {
notificationManager = (NotificationManager)
getSystemService(Context.NOTIFICATION_SERVICE);
int icon = R.drawable.iconToDisplayOnNotification;
long when = System.currentTimeMillis();
final Notification notification = new Notification(icon, tickerText, when);
final Context context = getApplicationContext();
final CharSequence contentTitle = "titleForNotification";
final CharSequence contentText = "TextForNotification";
Intent notificationIntent = new Intent(this, ActivityTobeCalledOnNotificationSelect.class);
final PendingIntent contentIntent = PendingIntent.getActivity(this,0, notificationIntent, 0);
notification.setLatestEventInfo(context, contentTitle,contentText, contentIntent);
notificationManager.notify(NOTIFICATION_EX, notification);
Toast.makeText(this, "Started!", Toast.LENGTH_LONG);
timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
// Check if there are updates here and notify if true
Log.w(TAG,"run");
}
}
,10, UPDATE_INTERVAL);
return START_STICKY ;
}
@Override
public IBinder onBind(Intent intent) {
// TODO Auto-generated method stub
return null;
}
}
