Android for activity background run

Sometimes it is necessary to have the activity run in the background in the following ways:

In Androidmanifest.xml, the activity attribute is increased:

Android:theme= "@style/backgroundonly"
Android:configchanges= "Orientation|keyboardhidden"

Add the following as follows:

<activity android:name= "Activityname"
Android:label= "@string/app_name"
Android:theme= "@style/backgroundonly"
android:configchanges= "Orientation|keyboardhidden" >

Style.xml content is as follows:

<resources>
<style name= "Backgroundonly" >
<item name= "Android:windowbackground" > @null </item>
<item name= "Android:windowcontentoverlay" > @null </item>
<item name= "Android:windowanimationstyle" > @null </item>
<item name= "Android:windownotitle" >true</item>
<!--<item name= "Android:windownodisplay" >true</item>
--><item name= "Android:windowisfloating" >true</item>
</style>
</resources>

In this way, the activity runs in the background and ends with finish () when you're done with your task.
