我有一个在启动完成时触发的接收器
public class StartupReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction() != null && intent.getAction().equals(Intent.ACTION_BOOT_COMPLETED)) {
Log.i("In" , "getAction() - Boot");
ReactivationService.enqueueWork(context, intent);
}
else
Log.i("No" , "Boot");
}
}
这会调用JobIntentService：
public class ReactivationService extends JobIntentService {
public static final int JOB_ID = 0x01;
public static void enqueueWork(Context context, Intent work) {
enqueueWork(context, ReactivationService.class, JOB_ID, work);
}
@Override
protected void onHandleWork(@NonNull Intent intent) {
Log.i("In" , "onHandleWork()");
NotificationService.setNotificationServiceAlarm(this, new Prefs(this).getNotifs());
...
}
}
这是我的NotificationService类：
public class NotificationService extends IntentService {
private static final String TAG = "NotificationsService";
Prefs prefs;
Notification.Builder builder;
public NotificationService() {
super(TAG);
}
@Nullable
@Override
public IBinder onBind(Intent intent) {
return super.onBind(intent);
}
@Override
protected void onHandleIntent(Intent intent) {
CheckConnection checkNetwork = new CheckConnection(this);
if (!checkNetwork.isNetworkAvailable()) {
return;
}
Log.i("In" , "Notification onHandleIntent()");
prefs = new Prefs(this);
String city = prefs.getCity();
String units = prefs.getUnits();
try {
WeatherInfo weather;
Log.i("In" , "Request");
weather = new Request(this).getItems(city, units);
weatherNotification(weather);
} catch (IOException e) {
Log.e(TAG, "Error get weather", e);
}
}
public static Intent newIntent(Context context) {
Log.i("Trigger" , "newIntent");
return new Intent(context, NotificationService.class);
}
public static void setNotificationServiceAlarm(Context context,
boolean isNotificationEnable) {
if (context != null) {
Log.i("In", "Notification Service Alarm");
Intent intent = NotificationService.newIntent(context);
PendingIntent pendingIntent = PendingIntent.getService(context, 0, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
long intervalMillis = AlarmManager.INTERVAL_HOUR;
if (alarmManager != null && pendingIntent != null)
if (isNotificationEnable) {
Log.i("In", "Alarm Repeating");
alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime(),
intervalMillis,
pendingIntent);
} else {
Log.i("In", "Cancelled Pending Intent");
alarmManager.cancel(pendingIntent);
pendingIntent.cancel();
}
}
else
Log.i("Null" , "Context");
}
private void weatherNotification(WeatherInfo weather) {
Intent intent = new Intent(this, WeatherActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
Log.i("In" , "Weather Notification");
...
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
assert notificationManager != null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
String id = "w01", name = getString(R.string.weather_notification_title);
int importance = NotificationManager.IMPORTANCE_MIN;
String desc = getString(R.string.weather_notification_description);
NotificationChannel channel = new NotificationChannel(id, name, importance);
channel.setDescription(desc);
notificationManager.createNotificationChannel(channel);
builder = new Notification.Builder(this , id);
}
else
builder = new Notification.Builder(this);
...
Notification notification = builder.build();
notificationManager.notify(0 , notification);
}
}
在Boot Completion中我的logcat看起来像
10-09 11:00:59.469 5534-5534/? I/zygote64: Late-enabling -Xcheck:jni

在类似情况下，我还有一个升级接收器：
public class UpgradeReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction() != null && intent.getAction().equals(Intent.ACTION_MY_PACKAGE_REPLACED)) {
Log.i("In" , "getAction() - Upgrade");
ReactivationService.enqueueWork(context, intent);
}
else
Log.i("No" , "Upgrade");
}
}
这是触发时的logcat：
10-09 11:00:59.469 5534-5534/? I/zygote64: Late-enabling -Xcheck:jni
10-09 11:01:00.405 5534-5534/com.a5corp.weather I/InstantRun: starting instant run server: is main process

这意味着当我收到UpgradeReceiver时Job Intent服务正在工作，但StartupReceiver上没有。我不知道自己哪里出错了。帮助我。
