–The anonymous answer is my answer that I solved this issue with.–

I have been writing an app for Android, all is working well in Honeycomb, but not playing nice on my FroYo & Gingerbread devices (opposite of what you’d expect right).

Here is the code that I believe is causing the issue:

@Override
protected void onStart() {
    int versionNumber = Integer.valueOf(android.os.Build.VERSION.SDK);
    if (versionNumber == 11) {
        super.onStart();
        ActionBar actionBar = this.getActionBar();
        actionBar.setDisplayHomeAsUpEnabled(true);
    }
}

Here I implement the ActionBar’s icon-up-to-home ability, I added the versionNumber variable as I believed the lack of an ActionBar in pre-Honyecomb devices was causing the issue when the activity was run, but it still crashes and I believe this is the issue, although I am terrible with debugging and don’t understand anything I am given by logcat.

Edit: logcat – I hope I got the right section?!

    This always seems to happen, I ask the question and the problem becomes clearer in my mind after having explained it so someone not in the context could understand…

    The fix I found was:

    //Sets the icon to 'go home' button
@Override
protected void onStart() {
    int versionNumber = Integer.valueOf(android.os.Build.VERSION.SDK);
    if (versionNumber >= 11) {
            super.onStart();
            ActionBar actionBar = this.getActionBar();
            actionBar.setDisplayHomeAsUpEnabled(true);
    }
    else {
            super.onStart();
    }
}

    This fixes the problem in both Gingerbread & FroYo, the difference is that super.onStart(); us triggered no matter what.

    For those of you who are inevitably going to comment on my hackish/sticky tape fix: This particular App does not need an ActionBar always, I was just using the ActionBar items in Honeycomb as it has become the UI practice to get more actions. This is why I did not implement an Ac
