android - webview崩溃 - webviewfactory error instantiating provider




NameNotFoundException webview (2)

我从Crashlytics收到错误,表明某些设备缺少com.google.android.webview。 这怎么可能呢?

它只来自运行Lollipop的设备。 我在Nexus 5上测试了它,但我无法重现错误。 我正在使用proguard

我的MyWebView看起来像这样:

public class MyWebView extends WebView {

    public static final String tag = MyWebView.class.getName();
    private HtmlJSInterfaceNew js;

    public MyWebView(Context context) {
        super(context);
        gd = new GestureDetector(context, sogl);
        init();
    }

    public MyWebView(Context context, AttributeSet attrs) {
        super(context, attrs);
        gd = new GestureDetector(context, sogl);
        init();
    }

    public MyWebView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        gd = new GestureDetector(context, sogl);
        init();
    }

    @SuppressLint("NewApi")
    private void init() {
        setPadding(0, 0, 0, 0);
        MyWebViewClient myWebViewClient = new MyWebViewClient();        
        this.setWebViewClient(myWebViewClient);
        setWebChromeClient(new MyWebChromeClient());
        if(!isInEditMode())
        {
            getSettings().setAllowFileAccess(true);
            getSettings().setJavaScriptCanOpenWindowsAutomatically(false);
            getSettings().setJavaScriptEnabled(true);
            WebSettings webSettings = getSettings();

            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
                webSettings.setAllowContentAccess(false);
            }

            webSettings.setUseWideViewPort(true);


        }


    }
    public void addMyJavascriptInterface(HtmlJSInterfaceNew htmlJSInterface, String string) {
        js = htmlJSInterface;
        addJavascriptInterface(htmlJSInterface, string);
    }

    public class MyWebChromeClient extends WebChromeClient
    {
        public void onProgressChanged(WebView view, int progress) {
        }
    }
}

根本原因是:

android.util.AndroidRuntimeException: android.content.pm.PackageManager$NameNotFoundException: com.google.android.webview
       at android.webkit.WebViewFactory.getFactoryClass(WebViewFactory.java:161)

所以我认为它可能与proguard和JavascriptInterface有关。 有任何想法吗?

编辑:从grepcode我发现方法getFactoryClass:

private static Class<WebViewFactoryProvider> getFactoryClass() throws ClassNotFoundException {
        Application initialApplication = AppGlobals.getInitialApplication();
        try {
            // First fetch the package info so we can log the webview package version.
            String packageName = getWebViewPackageName();
            sPackageInfo = initialApplication.getPackageManager().getPackageInfo(packageName, 0);
            Log.i(LOGTAG, "Loading " + packageName + " version " + sPackageInfo.versionName +
                          " (code " + sPackageInfo.versionCode + ")");

            // Construct a package context to load the Java code into the current app.
            Context webViewContext = initialApplication.createPackageContext(packageName,
                    Context.CONTEXT_INCLUDE_CODE | Context.CONTEXT_IGNORE_SECURITY);
            initialApplication.getAssets().addAssetPath(
                    webViewContext.getApplicationInfo().sourceDir);
            ClassLoader clazzLoader = webViewContext.getClassLoader();
            Trace.traceBegin(Trace.TRACE_TAG_WEBVIEW, "Class.forName()");
            try {
                return (Class<WebViewFactoryProvider>) Class.forName(CHROMIUM_WEBVIEW_FACTORY, true,
                                                                     clazzLoader);
            } finally {
                Trace.traceEnd(Trace.TRACE_TAG_WEBVIEW);
            }
        } catch (PackageManager.NameNotFoundException e) {
            // If the package doesn't exist, then try loading the null WebView instead.
            // If that succeeds, then this is a device without WebView support; if it fails then
            // swallow the failure, complain that the real WebView is missing and rethrow the
            // original exception.
            try {
                return (Class<WebViewFactoryProvider>) Class.forName(NULL_WEBVIEW_FACTORY);
            } catch (ClassNotFoundException e2) {
                // Ignore.
            }
            Log.e(LOGTAG, "Chromium WebView package does not exist", e);
            throw new AndroidRuntimeException(e);
        }
    }

在Lollipop的Android System WebView应用程序更新后,很可能会在很短的时间内发生这种情况。

我在Google Play开发者控制台中看到了这个错误,但也无法在我的Nexus 5上重现它,无论我多么努力阻止我的应用访问Android系统WebView应用:

java.lang.RuntimeException: Unable to create application com.uninteresting.app.name:
    android.util.AndroidRuntimeException: android.content.pm.PackageManager$NameNotFoundException: com.google.android.webview

然后我们得知在System WebView应用程序更新后,我们的应用程序在某些设备上一直崩溃,因此我测试了它。 仍然没有结果,香草Nexus 5拒绝让我们的应用程序崩溃! 所以我尝试了其他制造商的其他手机(大约75%的报告来自三星Galaxy设备)突然间我们一直在崩溃。 我的测试方法:

  1. 打开您的应用程序,确保显示WebView。
  2. 打开Play商店,导航到“我的应用程序”,然后打开“Android System WebView”。 卸载更新。 这不应该让你崩溃,但是你应该看到你的app强制重启。
  3. 备份打开您的应用程序,让它从重新启动恢复。
  4. 返回Play商店并更新Android System WebView。
  5. 在更新过程中重新关注您的应用。 现在,如果您在受影响的设备上,它应该崩溃。 如果没有,您的应用程序将被推到后台并安静地重新启动。

我到目前为止所说的几点注意事项:

  • 我们的应用程序错误地 提前 启动WebView,因此我们在崩溃消息中“无法创建应用程序”。 用户甚至不必看着我们的应用程序崩溃。 我怀疑这适用于您,但如果您的应用尝试在此方案期间重新启动其包含WebView的活动,则可以解释它。
  • 我们100%的报告来自5.0设备,我不知道如何在Lollipop以下的任何地方发生这种情况。
  • 我们确实看到有关此错误的Nexus 4和Nexus 5的报告,因此我不知道为什么我无法在这些设备上重现它。 可能是一个单独的根本原因,但我需要进一步研究。

简而言之,我不会立即认为您正在使用ProGuard或JavascriptInterface做任何不正确的事情。 我非常强烈地倾向于将固件归咎于大多数报告的根本原因,导致应该是一个平滑的更新过程,而不是导致某些应用程序彻底崩溃。

编辑: 我运行了一些测试,结果发现所有未崩溃的设备都是5.0或5.0.1,而所有崩溃的设备都是5.0.2,所以我无法轻易指出原始设备制造商了。


这在Android上的chrome更新时发生:在更新期间,程序包不计入已安装,因此尝试在程序包管理器中查找它将失败。

对于我的情况,它持续了一段时间(应用程序一直崩溃),直到我实际 重启/重启设备 ,然后一切都很好。

您的代码没有任何问题,它只是处理更新的方式。
