java - Run application in the background -

-

i'm trying start groomdroid web server in android when starts, black window shown.

enter image description here

i'd start app in background without screen being shown.

i'm starting app in following way:

intent webserver = new intent(); webserver.setclassname("net.allory.groom","net.allory.groom.groomdroid"); startactivity(webserver);

i tried startservice(webserver); doesn't seem work.

can me ?

you should move background logic service, , when it's running create ongoing notification.

selecting notification should start activity (ui), , service can communicate data using handler.

also, if specify launchmode of activity singletask:

<activity android:name=".activity.youractivity"      android:launchmode="singletask"     android:alwaysretaintaskstate="true"     android:cleartaskonlaunch="false"      android:finishontasklaunch="false">     <intent-filter>         <action android:name="android.intent.action.main" />         <category android:name="android.intent.category.default" />     </intent-filter> </activity>

and on application start check if service running (say you've started application, , press icon again), you'll able start same task, instead of relaunching service and/or showing nothing.

this explanation might not clear, let me know if need more details :)
