Saya telah membuat implementasi sendiri untuk melakukan ini dengan cara sesederhana mungkin.
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import junit.framework.Assert;

public abstract class AbstractSystemServiceTask {
private final Context context;
private final AlarmManager alarmManager;
private final BroadcastReceiver broadcastReceiver;
private final PendingIntent pendingIntent;
public AbstractSystemServiceTask(final Context context, final String id, final long time, final AlarmType alarmType, final BackgroundTaskListener backgroundTaskListener) {
Assert.assertNotNull("ApplicationContext can't be null", context);
Assert.assertNotNull("ID can't be null", id);
this.context = context;
this.alarmManager = (AlarmManager) this.context.getSystemService(Context.ALARM_SERVICE);
this.context.registerReceiver(
this.broadcastReceiver = this.getBroadcastReceiver(backgroundTaskListener),
new IntentFilter(id));
this.configAlarmManager(
this.pendingIntent = PendingIntent.getBroadcast(this.context, 0, new Intent(id), 0),
time,
alarmType);
}
public void stop() {
this.alarmManager.cancel(this.pendingIntent);
this.context.unregisterReceiver(this.broadcastReceiver);
}
private BroadcastReceiver getBroadcastReceiver(final BackgroundTaskListener backgroundTaskListener) {
Assert.assertNotNull("BackgroundTaskListener can't be null.", backgroundTaskListener);
return new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
backgroundTaskListener.perform(context, intent);
}
};
}
private void configAlarmManager(final PendingIntent pendingIntent, final long time, final AlarmType alarmType) {
long ensurePositiveTime = Math.max(time, 0L);
switch (alarmType) {
case REPEAT:
this.alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), ensurePositiveTime, pendingIntent);
break;
case ONE_TIME:
default:
this.alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + ensurePositiveTime, pendingIntent);
}
}
public interface BackgroundTaskListener {
void perform(Context context, Intent intent);
}
public enum AlarmType {
REPEAT, ONE_TIME;
}
}
Satu-satunya langkah selanjutnya, terapkan.
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import ...AbstractSystemServiceTask;
import java.util.concurrent.TimeUnit;
/**

public class UpdateInfoSystemServiceTask extends AbstractSystemServiceTask {
private final static String ID = "UPDATE_INFO_SYSTEM_SERVICE";
private final static long REPEAT_TIME = TimeUnit.SECONDS.toMillis(10);
private final static AlarmType ALARM_TYPE = AlarmType.REPEAT;
public UpdateInfoSystemServiceTask(Context context) {
super(context, ID, REPEAT_TIME, ALARM_TYPE, new BackgroundTaskListener() {
@Override
public void perform(Context context, Intent intent) {
Log.i("MyAppLog", "-----> UpdateInfoSystemServiceTask");
//DO HERE WHATEVER YOU WANT...
}
});
Log.i("MyAppLog", "UpdateInfoSystemServiceTask started.");
}
}
Saya suka bekerja dengan implementasi ini, tetapi cara lain yang mungkin baik, itu tidak membuat AbstractSystemServiceTaskabstrak kelas, dan membangunnya melalui Builder.
Saya harap ini membantu Anda.
DIPERBARUI
Ditingkatkan untuk memungkinkan beberapa orang BackgroundTaskListenermelakukan hal yang sama BroadCastReceiver.
