Приложение не работает в более ранних версиях android

Question

У меня возникла проблема с приложением, которое я разработал. Дело в том, что APP работает для android 4.1, но не работает на android 2.3.7.

Значение min SDK установлено в 8 в файле manifest.xml.

Когда я отлаживался, я узнал, что это не удается при выполнении setContentView (R.layout.activity_uniflow_results); метод.

прилагается мой AndroidManifest.xml и JAVA, который не работает.

AndroidManifest.xml

странное дело в том, что метод setContentView используется в первой деятельности, но не проваливается там, не работает во втором действии при раздувании GUI

Space был добавлен в API 14 и поэтому недоступен на устройствах Gingerbread. Вы можете либо использовать View:

<View 
    android:layout_width="23dp" 
    android:layout_height="23dp" 
    android:layout_gravity="center" 
    android:id="@+id/space2"/> 

Или добавить поддержку библиотека-v7 (примечание: не v4) в свой проект, который содержит портированную версию Space:

<android.support.v7.widget.Space 
    android:layout_width="23dp" 
    android:layout_height="23dp" 
    android:layout_gravity="center" 
    android:id="@+id/space2"/>
