copied!<p>I have app with webview and I use <a href="https://github.com/ACRA/acra" rel="nofollow noreferrer">ACRA</a>. I receive crash reports from users with errors caused by interaction with <code>HTML5Video</code>. <em><p>Error 1:</em></p> <pre><code>"java.lang.NullPointerException at android.webkit.HTML5VideoViewProxy$VideoPlayer.exitFullScreenVideo(HTML5VideoViewProxy.java:180) at android.webkit.HTML5VideoViewProxy.exitFullScreenVideo(HTML5VideoViewProxy.java:770) at android.webkit.WebViewClassic$PrivateHandler.handleMessage(WebViewClassic.java:7422) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.app.ActivityThread.main(ActivityThread.java:5039) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:793) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:560) at dalvik.system.NativeStart.main(Native Method)" </code></pre> <p><em><p>Error 2:</em></p> <pre><code>"java.lang.NullPointerException at android.webkit.HTML5VideoFullscreen.switchProgressView(HTML5VideoFullscreen.java:455) at android.webkit.HTML5VideoView.enterFullscreenVideoState(HTML5VideoView.java:546) at android.webkit.HTML5VideoViewProxy$VideoPlayer.enterFullscreenVideo(HTML5VideoViewProxy.java:182) at android.webkit.HTML5VideoViewProxy.handleMessage(HTML5VideoViewProxy.java:479) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:155) at android.app.ActivityThread.main(ActivityThread.java:5485) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1028) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:795) at dalvik.system.NativeStart.main(Native Method)" </code></pre> <p>Here are my <a href="https://stackoverflow.com/a/4445105/1548085">DropBox</a> logs if needed: <p>for error 1: <a href="http://pastebin.com/w8G1UJvG" rel="nofollow noreferrer">http://pastebin.com/w8G1UJvG</a> <p> seems to be interesting:</p> <pre><code>11-14 22:19:29.912 E/libEGL (14744): call to OpenGL ES API with no current context (logged once per thread) 11-14 22:19:29.917 W/dalvikvm(14744): threadid=1: thread exiting with uncaught exception (group=0x40d4a2d0) </code></pre> <p>for error 2: <a href="http://pastebin.com/8BEK1vAm" rel="nofollow noreferrer">http://pastebin.com/8BEK1vAm</a> <p> seems to be interesting: </p> <pre><code>12-10 00:14:52.542 W/YourLogTag(24823): Couldn't find activity to view mimetype: video/x-m4v </code></pre> <p>In fact I even don't suggest interaction with HTML5 videos in my webview. I guess, users open them from pages, interaction with which is also not provided. Also I think it's a bad way to try to prohibit users interaction with other webpages (and it may be really hard in case of my app). But also, user definetely don't experience a warm feeling to my app, when crash dialog appears before him... <p> <strong>So I want to block users' interaction with HTML5 Video in my webview or just catch exceptions properly (seems to be not very good approach). What's the best way to do it?</strong></p> <p>Here are my webview settings, if they're required:</p> <pre><code>webView.getSettings().setJavaScriptEnabled(false); webView.getSettings().setUserAgentString("Some user agent"); </code></pre>

Querying!
