Title: Plugin crashes Android's WebView? Last modified: August 21, 2016 --- # Plugin crashes Android's WebView? * Resolved [jgadsby](https://wordpress.org/support/users/jgadsby/) * (@jgadsby) * [13 years, 1 month ago](https://wordpress.org/support/topic/plugin-crashes-androids-webview/) * Hi there, * First of all, love the plugin – makes the commenting experience much slicker. It also works fine on Android’s own web browser. * The problem is, it crashes WebView right as the green ‘comment posted’ message appears. It crashes my app with a ‘null pointer exception’. Any ideas at all? * Thanks! * [http://wordpress.org/extend/plugins/wp-ajaxify-comments/](http://wordpress.org/extend/plugins/wp-ajaxify-comments/) Viewing 6 replies - 1 through 6 (of 6 total) * [janjonas](https://wordpress.org/support/users/janjonas/) * (@janjonas) * [13 years, 1 month ago](https://wordpress.org/support/topic/plugin-crashes-androids-webview/#post-3673793) * Hi, * thanks for your comment. Do you have any further information about the error ? Is it a client side (JavaScript) error or an application (Java) error? Something like a StackTrace, line of code where the error occurred would be helpful to find the cause. Have you tried to disable the WP-Ajaxify-Comments plugin to make sure that the error is caused by the plugin? * Hope this helps… * Thread Starter [jgadsby](https://wordpress.org/support/users/jgadsby/) * (@jgadsby) * [13 years, 1 month ago](https://wordpress.org/support/topic/plugin-crashes-androids-webview/#post-3673794) * I’ve tried disabling the plugin and the site works normally – comments go through fine on the app. Here’s the (java?) error I see when the app crashes: * ``` 04-20 17:04:49.588: D/WebView(29814): onSizeChanged - w:480 h:762 04-20 17:04:51.743: I/GATE(29814): DEV_ACTION_COMPLETED 04-20 17:04:51.743: D/AndroidRuntime(29814): Shutting down VM 04-20 17:04:51.743: W/dalvikvm(29814): threadid=1: thread exiting with uncaught exception (group=0x40fdc2a0) 04-20 17:04:51.938: E/AndroidRuntime(29814): FATAL EXCEPTION: main 04-20 17:04:51.938: E/AndroidRuntime(29814): java.lang.NullPointerException 04-20 17:04:51.938: E/AndroidRuntime(29814): at com.shuffleelffuhs.shufflemylife.MainActivity$WebClientClass.onPageFinished(MainActivity.java:110) 04-20 17:04:51.938: E/AndroidRuntime(29814): at android.webkit.CallbackProxy.handleMessage(CallbackProxy.java) 04-20 17:04:51.938: E/AndroidRuntime(29814): at android.os.Handler.dispatchMessage(Handler.java) 04-20 17:04:51.938: E/AndroidRuntime(29814): at android.os.Looper.loop(Looper.java) 04-20 17:04:51.938: E/AndroidRuntime(29814): at android.app.ActivityThread.main(ActivityThread.java) 04-20 17:04:51.938: E/AndroidRuntime(29814): at java.lang.reflect.Method.invokeNative(Native Method) 04-20 17:04:51.938: E/AndroidRuntime(29814): at java.lang.reflect.Method.invoke(Method.java:511) 04-20 17:04:51.938: E/AndroidRuntime(29814): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java) 04-20 17:04:51.938: E/AndroidRuntime(29814): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java) 04-20 17:04:51.938: E/AndroidRuntime(29814): at dalvik.system.NativeStart.main(Native Method) ``` * Thread Starter [jgadsby](https://wordpress.org/support/users/jgadsby/) * (@jgadsby) * [13 years, 1 month ago](https://wordpress.org/support/topic/plugin-crashes-androids-webview/#post-3673795) * The specific code in the app that seems to be breaking: * ``` @Override public void onPageFinished(WebView view, String url) { super.onPageFinished(view, url); pd.dismiss(); pd = null; } } } ``` * This code basically just dismisses a ‘loading’ popup in the app once a page has finished loading. I suppose there’s some bug here because the comments code isn’t technically reloading the page? I’m not sure. * Also note that there are other AJAX elements being used on the site but these don’t seem to crash? * [janjonas](https://wordpress.org/support/users/janjonas/) * (@janjonas) * [13 years, 1 month ago](https://wordpress.org/support/topic/plugin-crashes-androids-webview/#post-3673800) * I don’t know the internals of your Android application, but you may have to check if `pd` is (already) `null` before calling `dismiss()` in the `onPageFinished` method. * [janjonas](https://wordpress.org/support/users/janjonas/) * (@janjonas) * [12 years, 11 months ago](https://wordpress.org/support/topic/plugin-crashes-androids-webview/#post-3673919) * Problem seems to be fixed.
