java.lang.IllegalArgumentException: parameter must be a descendant of this view

3.3k views Asked by At

I'm getting multiple crashes with this message parameter must be a descendant of this view from various Redmi devices. I have read similar questions on stackoverflow but I couldn't understand their solutions. As these logs don't include the activity or function names, I'm confused about where to start.

My app has lot of activities and fragments. How can I find the component causing this crash?

I'm not able to reproduce this crash. Any thoughts?

The error is being thrown by the following code in ViewGroup.java. See here.

/**
 * Helper method that offsets a rect either from parent to descendant or
 * descendant to parent.
 */
void offsetRectBetweenParentAndChild(View descendant, Rect rect,
        boolean offsetFromChildToParent, boolean clipToBounds) {

...

    // now that we are up to this view, need to offset one more time
    // to get into our coordinate space
    if (theParent == this) {
        if (offsetFromChildToParent) {
            rect.offset(descendant.mLeft - descendant.mScrollX,
                    descendant.mTop - descendant.mScrollY);
        } else {
            rect.offset(descendant.mScrollX - descendant.mLeft,
                    descendant.mScrollY - descendant.mTop);
        }
    } else {
        throw new IllegalArgumentException("parameter must be a descendant of this view");
    }
}
...

From another question related to the same error message, it looks like there was an attempt to add a view to two ViewGroups. The "parameter" in the message is the "descendant" View and "this view" is the ViewGroup.

I will guess that you are doing something similar, although there is not enough information to immediately identify the source of the problem. A view can only have one parent.
