膨胀 WebView XML 时出错

Question

我在三星 SM G920F (Galaxy S6) 版本 5.1.1 中发现了一份关于 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webview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" />

这就是我将它包含在活动布局中的方式：

<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，因此我提供了所有代码（简化）。 这是一份报告，因此仅在此设备上发生过一次，有人可以解释一下原因吗？

Answer 1

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（用户可能正在使用自定义 ROM 而没有安装它们。）

如果你有更多关于错误终端的信息，我会说你去吧，但你必须看到你拥有的用户/users_with_this_error 的比例。然后你可以看看它对你在这个问题上的工作是否有用。

来自断线的评论： 看看这个帖子，看起来有点像同一个问题：NameNotFoundException webview

Answer 2

我在 crashlytics 上遇到了同样的错误。

在 Google 上进行了一些搜索后，似乎当用户没有在手机上安装 webview 时会发生这种情况。

这听起来很奇怪，因为 webview 是一个系统包，但是有一个错误，当用户使用应用程序时更新 webview 包时，它实际上是可能的。 它不适用于所有手机，因此可以在某些特定设备上复制（我猜主要是三星设备...），但不能在其他设备上复制。

我不记得确切的步骤复制它，但类似：

• 启动应用程序
• 前往 Play 商店并卸载 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 web 视图，它会崩溃。

不知道如何处理它。 我想您可以查看软件包是否存在或注册以收到有关软件包更新的通知以重新加载应用程序。 就我而言，这确实是一个极端情况，发生了一两次，我认为不需要解决这个问题。如果它更频繁地发生，可能需要采取一些措施。

Answer 3

正如@simon-ninon 所说，这就是我在我的应用中实现的方式。

在 UI 中膨胀 Webview 的活动的 onCreate 中，您 可以有一个 try-catch 来避免在 崩溃分析。

  /**
     * 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，可以带用户到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)
    }
}

Answer 4

在 Android 5.0 和 5.1 Lollipop (API 21/22) 上使用某些 AndroidX Jetpack 库的 1.1.0 版时会出现此崩溃问题：

implementation "androidx.appcompat:appcompat:1.1.0"

或

implementation "androidx.preference:preference:1.1.0"

当您的设备没有从 Google Play 商店安装 Google Chrome 浏览器或“Android System WebView”时，就会发生这种情况。因此，一些未安装 Google Play 服务的股票模拟器会遇到此问题。

如何解决

更新到更高的 AndroidX 版本，如 1.2.0-alpha03 将修复它，如下所述：

Error inflating class android.webkit.WebView Crash on Lollipop when opening PDF

implementation "androidx.appcompat:appcompat:1.2.0-alpha03"

或者在AppCompatActivity.applyOverrideConfiguration() 中使用自定义修复。见：android.view.InflateException Error inflating class android.webkit.WebView

另见：

• WebView Crash on Android 5-5.1 (API 21-22) Resources$NotFoundException: String resource ID #0x2040002
• https://issuetracker.google.com/issues/141132133 -- "webview 使用 appcompat1.1.0 崩溃"

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 Google 软件包的问题

 if(getPackageManager().hasSystemFeature("android.software.webview") == true && isPackageExisted("com.google.android.webview")) {
                if (Constant.isNetworkConnected(LoginActivity.this)) {

                     //Your Intent 
                } else {
                    Toast.makeText(getApplicationContext(), resources.getString(R.string.internet_error), Toast.LENGTH_SHORT).show();
                }
            }else
                {
                    Constant.showDialog(LoginActivity.this,"Please install the webview");
                }
        }
