This is my code:

Frame.gameController.test();
setContentView(Frame.world.getScreen());
Frame.world.setRunning(true);

On the second line I am getting the following error:

ERROR/AndroidRuntime(15229): Caused by: java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

Can anyone help me solve it? Previously it was working just fine, the problem starts when I take it in another activity.

I'm using android 2.2.

Maybe you are trying to set content from objects that already have parent. It looks like you set some views in one activity, for example:

TextView tv = new TextView();
layout.adView(tv);
layout2.adView(tv);

and that error appears when you try to add that tv to different layout. In your situation it's because Layout from one activity is trying to be set as a child in the other activity.

You have to release child from other parent first.
