Saya mendapatkan kesalahan dari Crashlytics yang menunjukkan bahwa beberapa perangkat hilang com.google.android.webview. Bagaimana itu mungkin?

Dan itu hanya dari perangkat yang menjalankan Lollipop. Saya telah mengujinya di Nexus 5 saya, tetapi saya tidak dapat mereproduksi kesalahan tersebut. Saya menggunakan proguard
MyWebView saya terlihat seperti ini:
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) {
}
}
}
Penyebab utamanya adalah:
android.util.AndroidRuntimeException: android.content.pm.PackageManager$NameNotFoundException: com.google.android.webview
at android.webkit.WebViewFactory.getFactoryClass(WebViewFactory.java:161)
Jadi saya pikir itu mungkin ada hubungannya dengan proguard dan mungkin JavascriptInterface. Ada ide?
EDIT: dari grepcode saya telah menemukan metode 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);
}
}

Jawaban:
Sepertinya ini terjadi dalam jangka waktu yang sangat singkat segera setelah pembaruan aplikasi WebView Sistem Android Lollipop.
Saya telah melihat kesalahan ini di Konsol Pengembang Google Play, tetapi juga tidak pernah dapat mereproduksinya di Nexus 5 saya, terlepas dari seberapa keras saya mencoba menghentikan aplikasi saya agar tidak memiliki akses ke aplikasi Android System WebView:
Kemudian kami mendapat kabar bahwa aplikasi kami secara konsisten mogok dengan pesan di atas pada beberapa perangkat segera setelah pembaruan aplikasi System WebView, jadi saya mengujinya. Masih tidak ada hasil, vanilla Nexus 5 menolak untuk merusak aplikasi kami! Jadi saya mencoba ponsel lain dari pabrikan lain (sekitar 75% dari laporan kami berasal dari perangkat Samsung Galaxy) dan tiba-tiba kami macet secara konsisten. Metodologi pengujian saya:
Beberapa peringatan kecil dengan apa yang saya katakan sejauh ini:
Singkatnya, saya tidak langsung berpikir Anda melakukan sesuatu yang salah dengan ProGuard atau JavascriptInterface Anda. Saya bersandar sangat kuat untuk menyalahkan firmware sebagai akar penyebab sebagian besar laporan, menghasilkan apa yang seharusnya menjadi proses pembaruan yang lancar menjadi salah satu yang malah menyebabkan beberapa aplikasi langsung macet.
Sunting: Saya menjalankan beberapa tes lagi dan ternyata semua perangkat yang tidak crash adalah 5.0 atau 5.0.1, sementara semua perangkat yang mengalami crash adalah 5.0.2, jadi saya tidak dapat dengan nyaman mengarahkan jari saya ke OEM lagi.

Hal ini terjadi saat chrome memperbarui pada android: selama pembaruan, paket tidak dihitung sebagai terinstal sehingga upaya untuk mencarinya di pengelola paket akan gagal.
Untuk kasus saya, ini bertahan beberapa saat lebih lama (aplikasi terus macet) sampai saya benar-benar melakukan boot ulang / memulai ulang perangkat , maka semuanya baik-baik saja.
Tidak ada yang salah dengan kode Anda, hanya bagaimana pembaruan ditangani.

Saya menemukan cara untuk mereproduksi masalah ( htc one (m8) android 6.0 ).
Dalam aplikasi saya, saya menggunakan komponen Android System WebView di awal (dalam metode Activity.onCreate () ). Saya tahu ini adalah praktik yang buruk, tetapi ini hanya sebagai contoh.
Langkah:
