报警不会唤醒了我的服务 [英] Alarm Does Not Wake up my Service
本文介绍了报警不会唤醒了我的服务的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有以下的code，我希望不管是手机的这种状态报警调用我的服务。即使它在睡眠模式下，我需要它来访问互联网，并提出一些网络电话。
为什么它不工作时，手机处于睡眠模式？

解决方案
为什么它不工作时，手机处于睡眠模式？
由于 startService（）是异步的，而Android只能保证一个 _WAKEUP 报警器件保持清醒，直到的onReceive（）结束。您将需要一个 WakeLock ，直接或通过方式使用使用我的 WakefulIntentService 。
I have the following code, I expect that this alarm invokes my Service regardless of the state of the phone. Even if its in sleep mode, I need it to access the internet and make some network calls.
Why doesn't it work when the phone is in sleep mode ?
Alarm Manager
Calendar cal = Calendar.getInstance();
cal.add(Calendar.SECOND, 5);
AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent notifyintent = new Intent(this, OnAlarmReceiver.class);
notifyintent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
notifyintent.setAction("android.intent.action.NOTIFY");
PendingIntent notifysender = PendingIntent.getBroadcast(this, 0, notifyintent,
PendingIntent.FLAG_UPDATE_CURRENT);
am.setInexactRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 20 * 1000,
notifysender);
AlarmReceiver
public class OnAlarmReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
// PullPendingRequests.acquireStaticLock(context)
context.startService(new Intent(context, PullPendingRequests.class));
}
}
PullPendingRequests, PendingIntent
public class PullPendingRequests extends IntentService
public PullPendingRequests() {
super("PullPendingRequests");
me = this ;
}
@Override
final protected void onHandleIntent(Intent intent) {
Location myLocation;
Log.d("Taxeeta:PullPendingRequets", "Started Location");
if (God.locationManager == null)
God.locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
myLocation = God.locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (myLocation != null)
onLocationChanged(myLocation);
else {
God.notifications.setSpeedNotification();
}
Log.d("Taxeeta:PullPendingRequets", "Ended Location");
}
Manifest for permissions and other settings
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.READ_LOGS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
<!-- <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> -->
<service
android:name="com.taxeeta.PullPendingRequests"
android:enabled="true"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:theme="@android:style/Theme.Light.NoTitleBar" />
<receiver
android:name="com.taxeeta.support.OnAlarmReceiver"
android:exported="true" >
<intent-filter>
<action android:name="android.intent.action.NOTIFY" />
</intent-filter>
</receiver>
Edit : Should this work, it isn't for me ?
public class PullPendingRequests extends IntentService implements LocationListener {
private static final String NAME = "com.commonsware.cwac.wakeful.WakefulIntentService";
private static volatile PowerManager.WakeLock lockStatic = null;
private static PowerManager.WakeLock lock;
synchronized private static PowerManager.WakeLock getLock(Context context) {
if (lockStatic == null) {
PowerManager mgr = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
lockStatic = mgr.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, NAME);
lockStatic.setReferenceCounted(true);
}
return (lockStatic);
}
@Override
final protected void onHandleIntent(Intent intent) {
try {
lock = getLock(this.getApplicationContext());
lock.acquire();
Location myLocation;
Log.d("Taxeeta:PullPendingRequets", "Started Location");
if (God.locationManager == null)
God.locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
myLocation = God.locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
if (myLocation != null)
onLocationChanged(myLocation);
else {
God.notifications.setSpeedNotification();
}
Log.d("Taxeeta:PullPendingRequets", "Ended Location");
} finally {
if (lock.isHeld()) {
lock.release();
}
}
}
解决方案
Why doesn't it work when the phone is in sleep mode ?
Because startService() is asynchronous, and Android only guarantees that a _WAKEUP alarm will keep the device awake until onReceive() ends. You will need to use a WakeLock, either directly or by means of using my WakefulIntentService.
