Fix Android notifyDataSetChanged Not Working

If calling the notifyDataSetChanged() method in the Android adapter has no effect, it may be due to the following reasons:

1. The data source was not properly updated: Ensure that the data source has been properly updated before calling the notifyDataSetChanged() method.
2. Using the wrong adapter: Sometimes we might mistakenly use a different adapter, which can result in the notifyDataSetChanged() method not working.
3. The adapter is not properly bound to the ListView or RecyclerView: Make sure the adapter is correctly bound to the ListView or RecyclerView and the appropriate layout manager is set.
4. Confusion with rules causing issue: Enabling obfuscation rules in your project may result in the notifyDataSetChanged() method not working. To solve this problem, you can try disabling obfuscation rules or adjusting them.

If none of the above methods solve the issue, you can try using the notifyItemRangeChanged() method to refresh specific data items in the adapter, or try creating a new adapter to replace the original one. If the problem persists, it may be necessary to further examine the code logic and data updating process to resolve the issue.
