I want to start 'MultiActivity' from 'OtherActivity' that in another
application,
and when I back to homescreen (don't close 'MultiActivity' ), start
'MultiActivity' again,
need to save the state of 'MultiActivity'.
but when running in
backLayout.updateViewLayout(backgroundView, blp);
setContentView(backLayout);
Something has gone wrong.
java.lang.IllegalStateException: The specified child already has a
parent. You must call removeView() on the child's parent first.
at android.view.ViewGroup.addViewInner(ViewGroup.java:1785 )
at android.view.ViewGroup.addView(ViewGroup.java:1680)
......
at com.android.internal.policy.impl.PhoneWindow.setContentView
(PhoneWindow.java:261)
at android.app.Activity.setContentView(Activity.java:1581)
Does anyone know what's wrong with this app,
Thanks in advance!
