问题:

膨胀WebView XML时出错

侯沈义
2023-03-14

我在三星SM G920F(Galaxy S6)5.1.1版中发现了Crashlytics的崩溃报告(在所有其他设备上,我没有检索到相同的错误)。

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.mypackage/com.mypackage.myactivity}: 
android.view.InflateException: Binary XML file line #21: Error inflating class android.webkit.WebView

这是我的网络视图的布局(样式为空样式):

<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/my_webview_id"
    style="@style/MyEmptyStyle"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@android:color/transparent" />

以下是我如何将其包括在活动布局中:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include layout="@layout/my_webview_layout"
        android:visibility="gone"/>
</LinearLayout>

报告的错误是XML错误,所以我提供了所有代码(简化)。这是一个单一的报告,所以它只在这个设备上发生过一次,有人能解释一下为什么吗?

编辑(完成堆栈跟踪)

正如西蒙·尼农所说,这就是我在应用程序中实现的方式。

在UI中膨胀Webview的活动的创建过程中,您可以尝试捕获以避免Crashlytics中产生的错误。

  /**
     * This element touches the UI elements
     * of the application and set them up.
     */
   try {
        setContentView(R.layout.activity_main);
        // ... further setup
    } catch (Exception ex) {
        transferToNoPackageFoundActivity(ex.getMessage());
    }


    private void transferToNoPackageFoundActivity(String errorMessage) {
        Intent intent = new Intent(this, NoPackageFoundActivity.class);
        intent.putExtra(Intent.EXTRA_INTENT, errorMessage);
        startActivity(intent);
        finish();
    }

在NoPackageFoundActivity中,您可以将用户带到Playstore下载webview包。

    /**
 * This field is used for presenting the user
 * with an error image for no connectivity.
 */
private lateinit var mErrorImage: ImageView

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_no_network)
    // get the intent for the error message, if any.
    val intent: Intent = intent
    if (intent.hasExtra(Intent.EXTRA_INTENT)) {
        println(intent.getStringExtra(Intent.EXTRA_INTENT))
    }

    mErrorImage = findViewById(R.id.error_image)
    mErrorImage.contentDescription = resources.getString(R.string.no_network_image_desc)
    Glide.with(this)
            .load(R.drawable.ic_no_web_view_illustration)
            .into(mErrorImage)

    val enableButton = findViewById<Button>(R.id.error_handler_btn)
    enableButton.setOnClickListener { openGooglePlayStore() }
    enableButton.text = resources.getString(R.string.no_package_btn_text)

    val reloadText = findViewById<TextView>(R.id.no_network_reload)
    reloadText.setOnClickListener { reloadApplication() }

    val errorHeadingText = findViewById<TextView>(R.id.error_heading)
    val errorSubheadingText = findViewById<TextView>(R.id.error_subheading)
    errorHeadingText.text = resources.getString(R.string.no_package_heading_text)
    errorSubheadingText.text = resources.getString(R.string.no_package_subheading_text)
}

/**
 * This is a onClickListener Handler that
 * reloads the application when the user
 * clicks on it.
 * It starts the activity again from
 */
private fun reloadApplication() {
    val intent = Intent(this, SplashScreen::class.java)
    startActivity(intent)
    finish()
}

private fun openGooglePlayStore() {
    // you can also use BuildConfig.APPLICATION_ID
    val appId = "com.google.android.webview"
    val rateIntent = Intent(Intent.ACTION_VIEW,
            Uri.parse("market://details?id=$appId"))
    var marketFound = false
    // find all applications able to handle our rateIntent
    val otherApps = packageManager
            .queryIntentActivities(rateIntent, 0)
    for (otherApp in otherApps) { // look for Google Play application
        if (otherApp.activityInfo.applicationInfo.packageName
                == "com.android.vending") {
            val otherAppActivity = otherApp.activityInfo
            val componentName = ComponentName(
                    otherAppActivity.applicationInfo.packageName,
                    otherAppActivity.name
            )
            // make sure it does NOT open in the stack of your activity
            rateIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
            // task reparenting if needed
            rateIntent.addFlags(Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED)
            // if the Google Play was already open in a search result
            //  this make sure it still go to the app page you requested
            rateIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)
            // this make sure only the Google Play app is allowed to
            // intercept the intent
            rateIntent.component = componentName
            startActivity(rateIntent)
            marketFound = true
            break
        }
    }
    // if GP not present on device, open web browser
    if (!marketFound) {
        val webIntent = Intent(Intent.ACTION_VIEW,
                Uri.parse("https://play.google.com/store/apps/details?id=$appId"))
        startActivity(webIntent)
    }
}

我的crashlytics也有同样的错误。

在Google上进行一些搜索后,当用户在手机上没有安装webview时,似乎会发生这种情况。

这听起来很奇怪,因为webview是一个系统包,但有一个bug,当用户在使用应用程序时更新webview包实际上是可能的。它并不适用于所有手机,所以它可以在一些特定的设备上复制(我想大部分是三星的…),但不适用于其他人。

我记不清具体的步骤,但有点像:

  • 启动应用程序
  • 转到play store并卸载web视图更新
  • 开始安装更新并切换回应用程序
  • 在某些设备上,在更新结束时,应用程序会重新启动,并且运行良好。在某些情况下,会出现错误,如果您尝试加载webview,它会崩溃

不知道该怎么处理。我想你可以看看软件包是否存在,或者注册以在软件包更新时收到通知以重新加载应用程序。在我的情况下,这确实是一个角落的情况,发生了一次或两次,我认为不需要努力解决这个问题。如果这种情况发生得更频繁,可能需要采取一些行动。

当应用程序膨胀WebView时,似乎发生了一些奇怪的事情,可能是什么。

对于NameNotFoundException:com.google.android.webview我可以推断出这可能是Google软件包的问题(用户可能使用自定义ROM而没有安装它们。)

如果你有更多关于终端错误的信息,我会说你去做,但是你必须看到你拥有的用户/users_with_this_error的比例。然后你可以看看它是否对你在这个问题上的工作有用。

从breakline的评论来看:看看这篇文章,看起来有点像同一个问题:NameNotFoundException webview
