Answer 1

You can use PackageManager.hasSystemFeature with PackageManager.FEATURE_TOUCHSCREEN_MULTITOUCH

There is an interesting series of articles on Android multi-touch that are worth a look

Answer 2

public final String SUPPORT = "Supported";
public final String NOT_SUPPORT = "None";

if (getPackageManager().hasSystemFeature(
                PackageManager.FEATURE_TOUCHSCREEN_MULTITOUCH)) {
            aDisplayInfo.multiTouch = SUPPORT;
        } else {
            aDisplayInfo.multiTouch = NOT_SUPPORT;
        }

Answer 3

If you need multitouch, include:

<uses-feature android:name="android.hardware.touchscreen.multitouch" />

in your manifest. Your application will not be listed in the Market for devices that lack multitouch.

If you wish to conditionally support multitouch, use PackageManager and hasSystemFeature() to see if android.hardware.touchscreen.multitouch is available.

Answer 4

A quick example:

boolean multi = 
getPackageManager().hasSystemFeature(PackageManager.FEATURE_TOUCHSCREEN_MULTITOUCH);
