Support deprecated and new API

Question

Is there any way I can support both deprecated and new API in the same method call for Android? I'm using the camera API which seems to be deprecated for the Lollipop version, so I tried to handle it like this:

    if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.LOLLIPOP)
    {
       //Before Lollipop, use the Camera API since it still supported.
    }
    else
    {
        //Use the CameraManager
        try
        {
            for (int i= 0; i < _camera.getCameraIdList().length; i++)
            {
                System.out.println("Camera= " + _camera.getCameraIdList()[i]);
            }
        }
        catch (CameraAccessException e)
        {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

But this does however just give me the error Call requires API level 21 (current min is 15): android.hardware.camera2.CameraManager#getCameraIdList I tried SupressLint and TargetApi but that only made the device running an earlier (before Lollipop) Android version crash when creating an class instance of this type.

Thanks for any help!

Answer 1

Simply having code in a class does not crash any Android 2.0+ device - code actually needs to run for it to crash. Check to make sure all of your Lollipop specific code is wrapped in version checks.

Answer 2

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
               //handler lollipop and higher 
            } else {
               //earlier api calls
            }
