扩展WebView XML时出错

标签： android xml webview

我发现三星SM G920F（Galaxy S6）版本5.1.1中的Crashlytics崩溃报告（在我没有检索到相同错误的所有其他设备上）。

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（样式是空样式）：

<?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" />

这是我在活动布局中包含它的方式：

<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，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（完整的堆栈跟踪）

当应用程序给WebView充气时，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。）

如果你有关于终端的更多信息并且错误我会说你去了，但你必须看到你拥有的users / users_with_this_error的比例。那么你可以看看它是否对你在这个问题上的工作有用。

来自breakline的评论： 看看这篇文章，看起来有点像：NameNotFoundException webview

答案 1 :(得分：3)

我的崩溃现象出现了同样的错误。

在Google上进行一些搜索后，似乎当用户手机上没有安装webview时就会发生这种情况。

这听起来很奇怪，因为webview是一个系统包，但是当用户使用应用程序时更新webview包时，实际上存在一个错误。 它不适用于所有手机，因此可以在某些特定设备上复制（我猜三星主要是......），但不能在其他设备上播放。

我不记得该步骤确实重现了它，但是类似于：

  • 启动应用
  • 转到商店并卸载网络视图更新
  • 开始安装更新并切换回应用
  • 在某些设备上，在更新结束时，应用程序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，则会崩溃。

不确定如何处理它。 我想您可以查看包是否存在或注册以通知包更新以重新加载应用程序。 在我的情况下，它确实是一个角落案件，发生了一两次，我不认为它需要解决问题。如果它经常发生，可能需要采取一些行动。

正如@ simon-ninon所说，这就是我在应用程序中使用的方式。

  

在使UI中的Webview膨胀的活动的onCreate中，您可以   可以尝试捕获以使自己免受错误产生的影响   速成游戏。

  /**
     * 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软件包。

    /**
 * 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?) {

    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)
}

/**

    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

            )
            // 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

            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)
    }
}

当使用某些AndroidX Jetpack库的1.1.0版本时，此崩溃问题发生在Android 5.0和5.1 Lollipop（API 21/22）上：

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，某些未安装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）将对其进行修复，如此处所述：

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

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

或在AppCompatActivity.applyOverrideConfiguration()中使用自定义修订。参见：android.view.InflateException Error inflating class android.webkit.WebView

当应用膨胀WebView时，似乎发生了一些奇怪的事情。 对于NameNotFoundException：Google软件包的com.google.android.webview问题

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