使用意圖在jar中啓動新活動時發生java.lang.NoClassDefFoundError

主項目依賴於名爲'sf'的庫。

在庫 '科幻'，使用意向，開始新的activeity使用意圖在jar中啓動新活動時發生java.lang.NoClassDefFoundError

import com.sf.proxy.MainActivity; 
public void login(Activity context) { 
    Intent intent = new Intent(context,MainActivity.class); 
    context.startActivity(intent); 
}

我得到了一個異常說：

的Manifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.sample"> 

    <supports-screens 
     android:anyDensity="true" 
     android:largeScreens="true" 
     android:normalScreens="true" /> 
    <application 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme"> 
     <activity 
      android:name="com.sf.proxy.MainActivity" 
      android:configChanges="orientation|screenSize|keyboardHidden" 
      android:screenOrientation="sensor" 
      android:theme="@android:style/Theme.Translucent.NoTitleBar"> 
     </activity> 
    ......

我知道這個例外意味着什麼，所以首先我看着罐子裏面e，和「失蹤」的課程確實存在。所有人都經歷過這種情況？提前致謝。
