我从 Crashlytics 收到错误消息,指出某些设备缺少 com.google.android.webview。这怎么可能?

而且它仅来自运行 Lollipop 的设备。我已经在我的 Nexus 5 上对其进行了测试,但我无法重现该错误。我正在使用 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) {
}
}
}

根本原因主要是:

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 以及可能与 JavascriptInterface 有关。有什么想法吗?

编辑:从 grepcode 我找到了 getFactoryClass 方法:

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);
}
}

最佳答案

这很可能发生在 Lollipop 的 Android System WebView 应用程序更新后的很短的时间内。

我在 Google Play 开发控制台中看到了这个错误,但也从来没有能够在我的 Nexus 5 上重现它,不管我多么努力地阻止我的应用程序访问 Android System WebView 应用程序:

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

然后我们得到消息,我们的应用程序在 System WebView 应用程序更新后立即在某些设备上持续崩溃并显示上述消息,所以我对此进行了测试。仍然没有结果, Vanilla Nexus 5 拒绝让我们的应用崩溃!所以我尝试了其他制造商的其他手机(我们的报告中大约 75% 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,确保正在显示 WebView。
  2. 打开 Play 商店,导航到“我的应用程序”,然后调出“Android 系统WebView。”卸载更新。这不应该让你崩溃,但你应该会看到您的应用强制重启。
  3. 打开您的应用备份,让它从重启中恢复。
  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,如果你在受影响的设备,它应该崩溃。如果没有,您的应用程序将只是被推到后台并安静地重新启动。

到目前为止我所说的一些小警告:

  • 我们的应用错误地非常早地启动了 WebView,因此我们的崩溃消息中出现“无法创建应用程序”的原因。用户甚至不必查看我们的应用程序就会崩溃。我怀疑这是否适用于您,但如果您的应用在这种情况下尝试重新启动包含 WebView 的 Activity,那就可以解释了。
  • 我们 100% 的报告来自 5.0 设备,我不知道这怎么会发生在 Lollipop 以下的任何设备上。
  • 我们确实看到 Nexus 4 和 Nexus 5 出现此错误的报告,所以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,但我需要进一步调查。

简而言之,我不会立即认为您在使用 ProGuard 或 JavascriptInterface 时做错了什么。我非常倾向于将固件归咎于大多数报告的根本原因,导致原本应该平稳的更新过程变成了导致某些应用彻底崩溃的过程。

编辑:我又进行了几次测试,结果发现所有没有崩溃的设备都是 5.0 或 5.0.1,而所有崩溃的设备都是 5.0.2,所以我不能再轻松地将矛头指向原始设备制造商了。
