The other has a try catch implemented in onInterceptTouchEvent. How is this error occuring then? Added code for the 2 viewpagers below
public class BottomBarViewPager extends ViewPager { public BottomBarViewPager(Context context) { super(context); } public BottomBarViewPager(Context context, AttributeSet attrs) { super(context, attrs); } @Override public boolean onTouchEvent(MotionEvent event) { return false; } @Override public boolean onInterceptTouchEvent(MotionEvent event) { return false; } } public class GalleryViewPager extends ViewPager { public static final String TAG = GalleryViewPager.class.getSimpleName(); private boolean swipeEnabled; public GalleryViewPager(Context context, AttributeSet attributes) { super(context, attributes); this.swipeEnabled = true; } @Override public boolean onTouchEvent(MotionEvent te) { if (this.swipeEnabled) { return super.onTouchEvent(te); } return false; } @Override public boolean onInterceptTouchEvent(MotionEvent me) { if (this.swipeEnabled) { /* This is caused by a bug in ViewPager and a solution is to catch the Exception and continue on. This only happens if you quickly tap with 2 fingers in different locations, rapidly. */ try { return super.onInterceptTouchEvent(me); } catch (IllegalArgumentException ex) { // SinclairLogger.e(TAG, "Caught exception in onInterceptTouchEvent", ex); } } return false; } public void setPagingEnabled(boolean enabled) { this.swipeEnabled = enabled; } } Added code for the viewpagers as requested

i have same problem (thanks to azi)
use ViewPagerFixed fixed your bug
public class ViewPagerFixed extends android.support.v4.view.ViewPager { public ViewPagerFixed(Context context) { super(context); } public ViewPagerFixed(Context context, AttributeSet attrs) { super(context, attrs); } @Override public boolean onTouchEvent(MotionEvent ev) { try { return super.onTouchEvent(ev); } catch (IllegalArgumentException ex) { ex.printStackTrace(); } return false; } @Override public boolean onInterceptTouchEvent(MotionEvent ev) { try { return super.onInterceptTouchEvent(ev); } catch (IllegalArgumentException ex) { ex.printStackTrace(); } return false; }} your xml file
<com.radesh.android.view.ViewPagerFixed xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/pager" android:layout_width="fill_parent" android:layout_height="fill_parent" /> BottomBarViewPager can extend to ViewPagerFixed

The above code I have used and it works for me. This error Exception java.lang.IllegalArgumentException: pointerIndex out of range android.view.MotionEvent.nativeGetAxisValue (MotionEvent.java) android.view.MotionEvent.getX (MotionEvent.java:2141)
might occur because of some sort of code like this which you might be using.
`int action = event.getAction(); int actionCode = action & MotionEvent.ACTION_MASK; if(actionCode == MotionEvent.ACTION_POINTER_UP || action == MotionEvent.ACTION_UP) { int which = action >> MotionEvent.ACTION_POINTER_ID_SHIFT; int id = event.getPointerId(which); float x = event.getX(id); float y = event.getY(id); Answers 3
Try using this:
@Override public boolean onTouchEvent(MotionEvent te) { return this.swipeEnabled && super.onTouchEvent(event); } @Override public boolean onInterceptTouchEvent(MotionEvent me) { return this.swipeEnabled && super.onInterceptTouchEvent(event); }
