Android Webview 在下拉單擊時崩潰

Question

Webview 加載但包含下拉列表。當我點擊該應用程序時崩潰

直到上個月，Webview 都運行良好，但現在在所有設備的 webview 中單擊下拉菜單時崩潰。
下面附上日志。

使用的依賴是

implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation('com.google.android.material:material:1.0.0')

Answer 1

由於我沒有您在最后使用的 URL，但嘗試了幾個在響應中有下拉列表的 URL，並且我的WebView在設備上運行良好。

我測試的設備是PIXEL 2, Samsung Galaxy S20+, S10+

這是我在項目中用於 AndroidX 的依賴項。

特別是，我建議先更新依賴項。

implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation 'androidx.core:core-ktx:1.5.0'
implementation 'androidx.appcompat:appcompat:1.3.0'
implementation 'com.google.android.material:material:1.3.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'

並且WebView的代碼非常正常。

binding.webView.settings.apply {
     // TODO Depending upon your requirement you can use these setting to be applied before loading the URL.
     // javaScriptEnabled = true
     // loadWithOverviewMode = true
     // javaScriptCanOpenWindowsAutomatically = true
}

binding.webView.apply {
    webViewClient = object : WebViewClient() {
        override fun shouldOverrideUrlLoading(
            view: WebView,
            url: String
        ): Boolean {
            Log.e("url coming from server", url)
            view.loadUrl(url)
                    return false;
        }
   }
   loadUrl("The URL you want to load here")
}

如果它仍然無法正常工作，那么您可能可以分享您的活動代碼。

Answer 2

您正在調用的對象已死亡，因為其托管進程不再存在。 參考這個線程

Answer 3

問題 - 我正在擴展 BaseActivity 類而不是 AppCompat Activity。

由於我最近在 Base Activity 中為我的應用添加了短語，因此 Web 視圖下拉菜單崩潰了。

我只是使用下面的代碼

WebViewActivity extends AppCompatActivity
