爲什麼我不能用語音識別開始我的活動？

Question

出於某種原因，我的搜索活動正在運行，但thumbsup活動無法啓動。它承認我說「三」，然後我的應用程序崩潰。我需要在這裏添加什麼來實現這個功能？

該應用程序能正常工作之前，我補充這部分：

if (textMatchList.get(0).contains("three")) { 
        // create an intent indicating we want 
         // to start the ThumbsUp activity. 
         // Important! Make sure your activity is 
         // in the AndroidManifest.xml file! 
         Intent i = new Intent(this, ThumbsUp.class); 

         // start the activity based on the Intent 
         startActivity(i); 

logcat的：

具有u在烏爾清單文件中加入這樣的：從logcat的

<Activity 
     android:name = "Packagename.class" 
     android:label = "@string/label" 
    > 

    </Activity>
