How to remove Black background between start new activity during slide_left animation?

Issue

When I call new activity by animation the background gets black.
How can I remove remove the black background?

For the animation I'm using:

getWindow().setBackgroundDrawableResource(R.drawable.mainbg_); 
overridePendingTransition (R.anim.push_up_in,0);

Solution

set the theme of that activity as transluscent in manifest file

android:theme="@android:style/Theme.Translucent"

so your code will be something like this

<activity android:name=".AdActivity"
        android:theme="@android:style/Theme.Translucent" />
