Call requires API level 14 (current min is 8): android.view.ViewGroup#canScrollHorizontally

Question

I am getting this error:

Call requires API level 14 (current min is 8): android.view.ViewGroup#canScrollHorizontally.

How I can resolve this in API level before 14?

public class ViewPagerEx extends ViewGroup{
    @Override
    public boolean performAccessibilityAction(View host, int action, Bundle args) {
        if (super.performAccessibilityAction(host, action, args)) {
            return true;
        }
        switch (action) {
            case AccessibilityNodeInfoCompat.ACTION_SCROLL_FORWARD: {
                if (canScrollHorizontally(1)) {
                    setCurrentItem(mCurItem + 1);
                    return true;
                }
            } return false;
            case AccessibilityNodeInfoCompat.ACTION_SCROLL_BACKWARD: {
                if (canScrollHorizontally(-1)) {
                    setCurrentItem(mCurItem - 1);
                    return true;
                }
            } return false;
        }
        return false;
    }

    public boolean canScrollHorizontally(int direction) {
        if (mAdapter == null) {
            return false;
        }
        final int width = getClientWidth();
        final int scrollX = getScrollX();
        if (direction < 0) {
            return (scrollX > (int) (width * mFirstOffset));
        } else if (direction > 0) {
            return (scrollX < (int) (width * mLastOffset));
        } else {
            return false;
        }
    }
}

go to AndroidManifest.xml you will find such code:

`<uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="19" />`

android:minSdkVersion is what your looking for, i means that your app will work on devises having the same API level.

android:targetSdkVersion is the API level that your app is designed to work on.

android:maxSdkVersion is the maximum API level your app can work on.

implies your app can work on devices between android:minSdkVersion and android:maxSdkVersion

so what you have to do is is changing you API level from 8 to 14 to support android.view.ViewGroup#canScrollHorizontally. since it was added in level 14 .

take into consideration that lowering android:minSdkVersion will support more android devices but you wouldn't be able to use methods introduced in higher API levels .

for more info check this detailed description

extra info :

1. kitkat 24.5% (API level 19)
2. JELLYBEAN 53.8% (API level 16,17,18)
3. ICECREAMSANDWICH 9.6% (API level 15 )
4. GINGERBREAD 11.4% (API level 10 )
5. FROYO 0.7% (API level 8 )

0.7% ??? you might think twice before setting android:minSdkVersion="8"

From @KenWolf's suggestion: Using the support-v4 library, you can use ViewCompat to check this:

// From within the View itself, just invoke the ViewCompat
// implementation with 'this' as the View parameter.
if (ViewCompat.canScrollHorizontally(this, 1)) {
    // ...
}

Give this a try: Try changing your local method name to something else, and call it. For example change it to canScrollHorizontallyLocal() and so where you are calling it. ViewGroup has a method named like that, and it might be trying the super method instead of yours.
