WebView issue on Android

Question

I use below code to read .html file with WebView, and open hyperlink with other browser app. ``` webView = (WebView)findViewById(R.id.terms_of_services_webview); String Path = "..."; //html file path WebSettings websettings = webView.getSettings(); websettings.setSupportZoom(true); websettings.setBuiltInZoomControls(true); websettings.setJavaScriptEnabled(true); webView.setWebViewClient(new WebViewClient() { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { if(url.equals(Path)) { view.loadUrl(url); } else { Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url)); TermsOfServicesActivity.this.startActivity(intent); } return true; } }); webView.loadUrl(Path); ``` The code all are in onCreate method. But I find blow code on Galaxy Tab 8.9(Android 4.0.4): ``` 11-20 16:24:49.613: W/webview(25896): java.lang.Throwable: Warning: A WebView method was called on thread 'WebViewCoreThread'.

Accepted Answer

As the warning says you are calling the webview methods in the `WebViewCoreThread`. Thus modify your code like this,

```
YourActivity.this.runOnUiThread(new Runnable() {
    public void run() {
       websettings.setSupportZoom(true);  
       websettings.setBuiltInZoomControls(true);   
       websettings.setJavaScriptEnabled(true);  
   webView.setWebViewClient(new WebViewClient() {
  @Override
  public boolean shouldOverrideUrlLoading(WebView view, String url) {
    if(url.equals(Path)) {
        view.loadUrl(url);
    }
    else {
        Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
        TermsOfServicesActivity.this.startActivity(intent);
    }
    return true;  
     }
 });

webView.loadUrl(Path);  
     }
});
```

OR

Try to write the below line in your `onCreate()` method before the `setContentView()`.

```
  StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
```
