Hello @BzCoder, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

Summary of Changes

This pull request updates MainActivity.java to add a null check for the mUrl parameter in the loadUrl method. It appears the intention is to prevent the app from crashing when a null URL is passed to the X5WebViewActivity.loadUrl method. However, the code also sets mUrl to null within the else block, which seems counterproductive and likely introduces a bug.

Highlights

• Null Check: Adds a null check for the mUrl parameter in the loadUrl method.
• Potential Bug: Sets mUrl to null within the else block after the null check, which might cause issues.

Changelog

• app/src/main/java/me/bzcoder/webview/MainActivity.java
  • Added a null check for the mUrl parameter in the loadUrl method.
  • Introduced a potential bug by setting mUrl to null within the else block.

Did you know?

The term "null pointer" was coined by Tony Hoare in 1965. He later apologized for inventing it, calling it his "billion-dollar mistake" because of the countless errors and system crashes it has caused.

Code Review

The code attempts to add a null check for the URL before loading it in the WebView. However, there are issues with the implementation that need to be addressed.

Summary of Findings

• Incorrect null check and assignment: The code attempts to check if mUrl is null, but uses assignment = instead of equality ==. Additionally, setting mUrl to null within the else block before passing it to X5WebViewActivity.loadUrl will always result in a null URL being loaded, regardless of the initial value of mUrl.

Merge Readiness

The pull request should not be merged until the critical issue with the null check and assignment is resolved. The current implementation will always load a null URL, which is likely not the intended behavior. After addressing the issues, another review should be performed to ensure the code functions as expected. I am unable to approve this pull request.

The null check is using = (assignment) instead of == (equality). Also, setting mUrl = null in the else block will always result in a null URL being loaded. The intention was likely to prevent loading a null URL, but the current implementation defeats that purpose. Consider removing the else block entirely, or modifying it to handle the case where mUrl is not null appropriately. If the intention is to prevent loading a null URL, then the else block is unnecessary.

        if(mUrl == null){
            return;
        }
        X5WebViewActivity.loadUrl(this, mUrl, mTitle);
