ABS + IntelliJ IDEA：無法啓動活動

正在關注this tutorial我在IntelliJ IDEA中爲我的Android項目添加了Maven，ABS和AndroidAnnotations。眼下ABS + IntelliJ IDEA：無法啓動活動

app deps

abs deps

我得到java.lang.RuntimeException: Unable to start activity錯誤：首先，我掙扎着DEX/cannot access android.support.v4.app.FragmentActivity例外，而且似乎具有以下配置修復它。

清單：

<?xml version="1.0" encoding="utf-8"?>

     <!-- uses-library android:name="com.google.android.maps" /-->

</manifest>

主要活動聲明：

public class TabsFragmentActivity extends SherlockFragmentActivity 
     implements TabHost.OnTabChangeListener

logcat的輸出：

我反編譯APK與apktool這裏是$ find . | grep support：

./smali/android/support 
./smali/android/support/v4 
./smali/android/support/v4/app 
./smali/android/support/v4/app/Watson$OnCreateOptionsMenuListener.smali 
./smali/android/support/v4/app/Watson$OnOptionsItemSelectedListener.smali 
./smali/android/support/v4/app/Watson$OnPrepareOptionsMenuListener.smali 
./smali/android/support/v4/app/Watson.smali 
./smali/com/actionbarsherlock/internal/view/View_HasStateListenerSupport.smali

這裏是代碼周圍TabsFragmentActivity.java:108：

public void onTabChanged(String tag) { 
    TabInfo newTab = this.mapTabInfo.get(tag); 
    if (mLastTab != newTab) { 
     FragmentTransaction ft = this.getSupportFragmentManager().beginTransaction(); 
     if (mLastTab != null) { 
      if (mLastTab.fragment != null) { 
       ft.detach(mLastTab.fragment); 
      } 
     } 
     if (newTab != null) { 
      if (newTab.fragment == null) { 
       newTab.fragment = Fragment.instantiate(this, 
         newTab.clss.getName(), newTab.args); 
       ft.add(R.id.realtabcontent, newTab.fragment, newTab.tag); 
      } else { 
       ft.attach(newTab.fragment); 
      } 
     } 

     mLastTab = newTab; 
     ft.commit(); 
     this.getSupportFragmentManager().executePendingTransactions(); 
    } 
}

向我們展示您的'CalendarActivity'和第108行的'TabsFragmentActivity' – WarrenFaith 2013-04-09 13:27:17

感謝您的快速回復，我已經爲該問題添加了第108行程序，這裏是['CalendarActivity']（https://gist.github.com/cfr/5345763） – Cfr 2013-04-09 13:44:17

ehm，第108行實際上是'newTab.fragment = Fragment.instantiate（this，newTab.clss.getName（），newTab.args）;' – Cfr 2013-04-09 13:46:58

的問題是非常基本的：我試圖把FragmentActivity而不是Fragment的標籤。 Here is ABS組的相關討論。
