ABS + IntelliJ IDEA：无法开始活动

Question

在this tutorial 之后，我在 IntelliJ IDEA 中的 Android 项目中添加了 Maven、ABS 和 AndroidAnnotations。起初我一直在为DEX/cannot access android.support.v4.app.FragmentActivity 异常而苦苦挣扎，并且似乎使用以下配置来修复它：

现在我收到java.lang.RuntimeException: Unable to start activity 错误。

清单：

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

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

主要活动声明：

public class TabsFragmentActivity extends SherlockFragmentActivity
        implements TabHost.OnTabChangeListener

Logcat 输出：

我用apktool反编译了APK，这里是$ 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

这里是 TabsFragmentActivity.java:108 的代码：

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();
    }
}

问题很基本：我试图在标签中输入FragmentActivity 而不是Fragment。 Here isABS组相关讨论。
