無法啟動活動ComponentInfo

Question

我當時正在使用Lex制作帶有語音操作的應用程序。 我通過將aar文件添加到項目的libs forler中並將這些行添加到gradle文件中來手動導入lex庫。

compile(name:'aws-android-sdk-core-2.4.0',ext:'jar')
compile(name:'aws-android-sdk-lex-2.4.0',ext:'aar')

我通過添加從庫中創建麥克風組件

 <?xml version="1.0" encoding="utf-8"?>
 <RelativeLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/white"
    tools:context="com.sample.app.MainActivity">

<com.amazonaws.mobileconnectors.lex.interactionkit.ui.InteractiveVoiceView xmlns:android="http://schemas.android.com/apk/res/android"
    class = "com.sample.app"
    android:layout_width="108dp"
    android:layout_height="108dp"
    android:layout_alignParentBottom="true"
    android:layout_centerInParent="true"
    android:background="@color/transparent"
    android:id="@+id/voiceInterface" />

</RelativeLayout>

當我嘗試運行該應用程序時，出現以下錯誤
