我的 android 应用程序需要在特定时间安排任务。它可以是每天、每周、每月等。因此，在插入输入数据时，如果用户选择“每天”。会有后台服务，每天都会插入相同的数据。
我试图创建服务和相应的接收器类，但是看起来服务没有自动运行。有人可以告诉我缺少什么吗？
接收器类
public class MyScheduleReceiver extends BroadcastReceiver {
// Restart service every 30 seconds
private static final long REPEAT_TIME = 1000 * 30;
@Override
public void onReceive(Context context, Intent intent) {
AlarmManager service = (AlarmManager) context
.getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(context, MyStartServiceReceiver.class);
PendingIntent pending = PendingIntent.getBroadcast(context, 0, i,
PendingIntent.FLAG_CANCEL_CURRENT);
Calendar cal = Calendar.getInstance();
// Start 30 seconds after boot completed
cal.add(Calendar.SECOND, 30);
//
// Fetch every 30 seconds
// InexactRepeating allows Android to optimize the energy consumption
service.setInexactRepeating(AlarmManager.RTC_WAKEUP,
cal.getTimeInMillis(), REPEAT_TIME, pending);
// service.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
// REPEAT_TIME, pending);
Toast.makeText(context, "Receving", Toast.LENGTH_SHORT).show();
}
public class MyStartServiceReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Intent service = new Intent(context, LocalWordService.class);
context.startService(service);
}
}
Android Menifest.xml
<service
android:name=".LocalWordService"
android:label="LocalWordService" >
</service>
<receiver android:name="MyScheduleReceiver" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<receiver android:name="MyStartServiceReceiver" >
</receiver>
现在，当我启动应用程序时，我调用一个活动类，它基本上使用下面的代码调用服务......但每 30 秒后什么都没有发生。
Intent mServiceIntent = new Intent(this, LocalWordService.class);
startService(mServiceIntent);
服务等级
public class LocalWordService extends Service {
private final IBinder mBinder = new MyBinder();
private ArrayList<String> list = new ArrayList<String>();
@Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this, "Starting", Toast.LENGTH_SHORT).show();
Random random = new Random();
if (random.nextBoolean()) {
list.add("Linux");
}
if (random.nextBoolean()) {
list.add("Android");
}
if (random.nextBoolean()) {
list.add("iPhone");
}
if (random.nextBoolean()) {
list.add("Windows7");
}
if (list.size() >= 20) {
list.remove(0);
}
return Service.START_NOT_STICKY;
}
@Override
public IBinder onBind(Intent arg0) {
return mBinder;
}
public class MyBinder extends Binder {
LocalWordService getService() {
return LocalWordService.this;
}
}
public List<String> getWordList() {
return list;
}
}
请指教，缺少什么？
