I have an ActionBar implemented as well as a SearchView widget in my app.

  • 0

I have an ActionBar implemented as well as a SearchView widget in my app. It works just fine on the Nexus 7, HTC Sensation, etc. – anywhere where the Android version is older than 3.0 I believe. But it doesn’t run on the phone with the Android 2.3.5.

Is there anyway to “not display” the action bar and other unsupported stuff when the program runs on the old device?

Here is the error log I get when run in on my old device, sorry for the length, don’t really understand which bit is useful:

P.S. I don’t want to use ActionBarSherlock!

    Oopsie,

    Remaining backward-compatible

    If you want to provide an action bar in your application and remain
    compatible with versions of Android older than 3.0, you need to create
    the action bar in your activity’s layout (because the ActionBar class
    is not available on older versions).

    To help you, the Action Bar Compatibility sample app provides an API
    layer and action bar layout that allows your app to use some of the
    ActionBar APIs and also support older versions of Android by replacing
    the traditional title bar with a custom action bar layout.

    Is it the answer to my question?

    Edit: that sample app is shit.
