我已经在这里查看了许多解决方案,但我似乎仍然无法每30秒启动一次服务。 30秒仅用于测试。报警设置代码如下,
Intent myIntent = new Intent(this, HeartRateService.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, myIntent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 7); // first time
long frequency= 60 * 500; // in ms
alarmManager.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
(SystemClock.elapsedRealtime() + frequency),
frequency, pendingIntent);
的manifest.xml
<service android:name=".heart_rate.HeartRateService"/>
我有一个心脏传感器服务,它在可穿戴设备上读取心率15秒,然后我使用stopSelf()停止它。我认为这可能是原因,但即使我把它拿出来,它仍然无效。
private void sendMessage(int heartRate, long dateTime) {
Log.d(TAG, "sendMessage: ");
PutDataMapRequest dataMap = PutDataMapRequest.create(WEARABLE_DATA_PATH);
dataMap.getDataMap().putInt("reading", heartRate);
dataMap.getDataMap().putLong("date_time", dateTime);
dataMap.getDataMap().putInt("sensor_type", mHeartSensor.getType());
PutDataRequest dataRequest = dataMap.asPutDataRequest();
PendingResult<DataApi.DataItemResult> pendingResult =
Wearable.DataApi.putDataItem(mGoogleApiClient, dataRequest);
new HeartRateService.SendMessageToDataLayer(WEARABLE_DATA_PATH, dataRequest).start();
stopSelf();
}
答案 0 :(得分:0)
原来我一直都没有开始服务,所以醒来时什么也没做。我创建了这个简单的广播接收器,以便在每个间隔启动服务。浪费了无数个小时,但吸取了教训。
