Answer 1

我想是因为你的AndroidManifest。试着把这个放在你的应用程序标签上

android:name="org.doubango.ngn.NgnApplication"

或

如果您有自定义的应用程序对象，则扩展NgnApplication对象而不是应用程序对象。

Answer 2

如果要在应用程序中使用imsdroid，则需要在android文件中使用ChromeView而不是WebView。我在这里找到了更多的信息

<us.costan.chrome.ChromeView
android:id="@+id/customWebView"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
/>
