Estou recebendo erros do Crashlytics que indicam que alguns dispositivos estão sem com.google.android.webview. Como isso é possível?

E é apenas a partir de dispositivos que executam o Lollipop. Eu testei no meu Nexus 5, mas não consigo reproduzir o erro. Estou usando proguard
Meu MyWebView se parece com isto:
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) {
}
}
}
A causa raiz pode ser:
android.util.AndroidRuntimeException: android.content.pm.PackageManager$NameNotFoundException: com.google.android.webview
at android.webkit.WebViewFactory.getFactoryClass(WebViewFactory.java:161)
Portanto, estou pensando que pode ter algo a ver com o proguard e talvez o JavascriptInterface. Alguma ideia?
EDIT: a partir do grepcode, encontrei o método 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);
}
}

Respostas:
É provável que isso esteja acontecendo no curto espaço de tempo imediatamente após as atualizações do aplicativo Android System WebView do Lollipop.
Eu tinha visto esse erro no Google Play Dev Console, mas também nunca fui capaz de reproduzi-lo no meu Nexus 5, independentemente de quanto eu realmente tentei impedir meu aplicativo de acessar o aplicativo Android System WebView:
Então, soubemos que nosso aplicativo estava travando consistentemente com a mensagem acima em alguns dispositivos imediatamente após as atualizações do aplicativo System WebView, então testei isso. Ainda sem resultados, o vanilla Nexus 5 se recusou a travar nosso aplicativo! Tentei outros telefones de outros fabricantes (cerca de 75% dos relatórios são de dispositivos Samsung Galaxy) e de repente travamos de forma consistente. Minha metodologia de teste:
Algumas pequenas advertências com o que eu disse até agora:
Resumindo, não acho que você esteja fazendo algo incorreto com o ProGuard ou sua interface Javascript. Estou fortemente inclinado a culpar o firmware como a causa raiz da maioria dos relatórios, resultando no que deveria ser um processo de atualização tranquilo que, em vez disso, faz com que alguns aplicativos travem completamente.
Edit: Eu executei mais alguns testes e descobri que todos os dispositivos que não travaram são 5.0 ou 5.0.1, enquanto todos os dispositivos que travaram eram 5.0.2, então não consigo apontar meu dedo confortavelmente Mais OEMs.

Isso acontece quando o Chrome é atualizado no Android: durante a atualização, o pacote não conta como instalado e, portanto, as tentativas de procurá-lo no gerenciador de pacotes falharão.
No meu caso, ele persistiu por mais algum tempo (o aplicativo continuou travando) até que eu realmente reinicie / reinicie o dispositivo , então está tudo bem.
Não há nada de errado com seu código, é apenas como as atualizações são tratadas.

Encontrei uma maneira de reproduzir o problema ( htc one (m8) android 6.0 ).
No meu aplicativo, eu uso o componente Android System WebView no início (no método Activity.onCreate () ). Eu sei que isso é uma prática ruim, mas isso é apenas por exemplo.
Passos:
