Hello, it seems that dx does not support syntax sugar removal.

error.zip The version I use is JDK17, gradle version 8.2, targetSDK 34. In higher versions, Google removed dx and adopted d8. I found that these errors are all syntax sugar errors

我验证了一段代码能够百分百复现。

private static void setRootView(Activity activity) {
    ViewGroup parent = (ViewGroup) activity.findViewById(android.R.id.content);
    for (int i = 0, count = parent.getChildCount(); i < count; i++) {
        View childView = parent.getChildAt(i);
        if (childView instanceof ViewGroup) {
            childView.setFitsSystemWindows(true);
            ((ViewGroup) childView).setClipToPadding(true);
        }
    }
}

当这段代码被转换时，会百分百NullPointExecption。 rootview.zip
