我在我的新应用程序中启动了一项服务.该服务是有前途的,带有通知.当在AVD 2.1 API Level 7中运行时,一切正常.但是当它在运行Gingerbread的三星Galaxy Tab上运行时,服务将启动(图标和应用程序名称显示在通知区域的顶部),但几秒钟后,服务就会消失.我可以看到的Log中的最后一个条目与我的App相关联,是我的Log.d(“Taglines”,“Return with with”START_STICKY)的结果,紧接在“return START_STICKY”之前.在我的服务的onStartCommand覆盖中,如下所示：
@Override
public int onStartCommand(Intent intent,int flags,int startId) {
int rc ;
Log.d("Taglines","onStartCommand()");
Toast.makeText(this,"Starting service TagsManager",Toast.LENGTH_SHORT).show();
Log.d("Taglines","Calling super.onStartCommand()");
rc = super.onStartCommand(intent,flags,startId);
Log.d("Taglines","super.onStartCommand return code was " + rc);
createNotification(INITIAL_NOTIFICATION_TEXT);
Log.d("Taglines","Returning with " + START_STICKY);
return START_STICKY ;
}
通知设置如下：
void createNotification(String text) {
Log.d("Taglines","createNotification called");
if (mNotificationManager == null) {
// Get a reference to the Notification Manager
String ns = Context.NOTIFICATION_SERVICE;
mNotificationManager = (NotificationManager) getSystemService(ns);
Log.d("Taglines","Obtained reference to Notification Manager");
}
// Instantiate the Notification
int icon = R.drawable.ic_notification;
CharSequence tickerText = "Taglines";
long when = System.currentTimeMillis();
notification = new Notification(icon,tickerText,when);
// Define Notification's expanded message and intent
Log.d("Taglines","createNotificacion() .. getApplicationContext");
context = getApplicationContext();
contentText = text;
// notificationIntent = new Intent(this,TagsOverview.class);
notificationIntent = new Intent(this,TagsServiceMenu.class);
contentIntent = PendingIntent.getActivity(this,notificationIntent,0);
notification.setLatestEventInfo(context,contentTitle,contentText,contentIntent);
// Pass the Notification to the NotificationManager:
Log.d("Taglines","createNotificacion() ... passing notification");
mNotificationManager.notify(NOTIFICATION_ID,notification);
Log.d("Taglines","Starting foreground");
startForeground(NOTIFICATION_ID,"Started");
}
这是服务启动时“adb logcat”的结果：
D/Taglines(21863): Starting service D/Taglines(21863): TagsManager(nullary) completed D/Taglines(21863): onStartCommand() D/Taglines(21863): Calling super.onStartCommand() D/Taglines(21863): super.onStartCommand eturn code was 2 D/Taglines(21863): createNotification called D/Taglines(21863): Obtained reference to Notification Manager D/Taglines(21863): createNotificacion() .. getApplicationContext D/Taglines(21863): createNotificacion() ... passing notification D/Taglines(21863): Starting foreground D/Taglines(21863): Started D/Taglines(21863): Returning with 1
在那之后,没有什么特别的(PID 21863什么都没有).只是一堆：
D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false W/InputManagerService( 302): Window already focused,ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@40bc06e8 D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false D/KeyguardViewMediator( 302): setHidden false
我不认为在这种情况下需要它,但这是AndroidManifest.xml的相关部分：
<service android:name=".TagsManager"
android:exported="false">
</service>
我哪里可能出错了？我可以提供哪些其他信息？
