I'm also awared of this problem in my app, which will run out of
memory after changing screen orientation for several times.
However, when I tried to create a whole new android application, the
problem persists.
Here is the code which is created by eclipse plugin. I just added the
getInstanceCount() in onDestroy:
package com.android.orienttest;
import android.app.Activity;
import android.os.Bundle;
public class orienttest extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public void onDestroy()
{
System.gc();
long ref = getInstanceCount();
super.onDestroy();
}
}
ref will increase each time i press Ctrl+F11 to change the orientation
of the screen.
# dumpsys meminfo -A 12 com.android.orienttest

We can see that the Activities has grown up to 14 after the test,
which should be 1 theoretically.
I'm currently using android sdk 1.5 r1.
Please someone give me the hint?
