错误膨胀类android.webkit.WebView偶尔会在生产中发生

d.a*_*mon 32 android webview

我的应用程序在Google Play上运行,并且在大多数设备上运行良好(数千名用户).但在极少数情况下(每日活跃用户百分比的一小部分),Error inflating class android.webkit.WebView当我在onCreateView方法中为我的片段扩充布局时,我会得到.完整堆栈跟踪如下:

我不明白什么是错的.因为这个错误来自在线报告工具(Crashlytics/Fabric),我无法分辨,每当特定用户尝试使用该片段时是否会发生这种情况,或者用户是否正常使片段膨胀并且错误仅在时间到达时发生时间.WebView小部件是系统的一部分,对吧？我的意思是 - 我不能错过我的制作APK - 就像支持库一样.或者我可以吗？

如果您从运行Android Lollipop的设备上看到这些报告,请忽略它们.当WebView软件包正在由Play商店更新(当前只能在Lollipop上发生)时,每当有人启动使用WebView的活动时,就会发生这种情况.在更新期间,程序包将被视为程序包管理器未安装.也就是说,您的应用没有任何问题.更新的软件包被认为不存在的时间窗口通常很小,因此当应用程序在崩溃后重新启动时,它将正常启动.

  • 仍然发生在Android 8上. (10认同)
  • 没关系,根本原因异常是"NameNotFoundException",这意味着WebView确实不存在于用户的设备中,这是一个设备错误,或者用户可能以root身份删除了WebView. (4认同)
  • 也在 Android 9 上（注 8）。这次崩溃是在最近 8 月份的 Note 8 更新之后发生的。更不用说我在 Play 商店中遇到了问题。我无法下载/更新任何应用程序。它只是说等待下载。除了重置手机之外，什么都试过了。没有解决问题 (2认同)

要解决出现在Android Lollipop上的此问题，您可以使用仅在Android Lollipop（API 21和22）上创建新配置的自定义WebView。使用此自定义WebView替换XML布局上的WebView。 

import android.annotation.TargetApi;
import android.content.Context;
import android.content.res.Configuration;
import android.os.Build;
import android.util.AttributeSet;
import android.webkit.WebView;

public class LollipopFixedWebView extends WebView {

    public LollipopFixedWebView(Context context) {
        super(getFixedContext(context));
    }

    public LollipopFixedWebView(Context context, AttributeSet attrs) {
        super(getFixedContext(context), attrs);
    }

    public LollipopFixedWebView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(getFixedContext(context), attrs, defStyleAttr);
    }

    // To fix Android Lollipop WebView problem create a new configuration on that Android version only
    private static Context getFixedContext(Context context) {
        if (Build.VERSION.SDK_INT == 21 || Build.VERSION.SDK_INT == 22) // Android Lollipop 5.0 & 5.1
            return context.createConfigurationContext(new Configuration());
        return context;
    }
}

如果您不依赖新的 Material DayNight 主题切换（或其他 UiMode 事件），您可以添加android:configChanges="uiMode"到 webview活动清单，以防止 AppCompatDelegate 更新资源配置，从而扰乱 webview 膨胀。
