我从Crashlytics收到错误，表明某些设备缺少com.谷歌.安卓网络视图.这怎么可能呢？

而且它只来自运行棒棒糖的设备.我已经在我的Nexus 5上测试过了，但我无法重现错误.我用的是proguard
我的MyWebView如下所示:
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) {
}
}
}
最根本的原因是:
android.util.AndroidRuntimeException: android.content.pm.PackageManager$NameNotFoundException: com.google.android.webview
at android.webkit.WebViewFactory.getFactoryClass(WebViewFactory.java:161)
所以我认为这可能与proguard和JavascriptInterface有关.有什么 idea 吗？
编辑:
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);
}
}
