Dropbox Sync API - 不满意的链接错误

我正在尝试DropboxSync在现有的Android应用程序中实现API.
我已下载DropboxSyncAPI并复制了Application的lib文件夹中的所有库.
我还将Native Library位置指向libDropboxSync.so所在的libs文件夹.

Manifest.xml

....
        
    
    
        
            

            

            
            
        
    

    

Main_Activity.java

public class Activity_Main extends Activity implements OnClickListener,
OnItemClickListener, OnTouchListener {
....
....
....
private DbxAccountManager mDbxAcctMgr;

onCreate(....)
{
//Application giving FATAL EXCEPTION on the line below.
mDbxAcctMgr = DbxAccountManager.getInstance((Activity)Activity_Main.this, DROPBOX_APP_KEY, DROPBOX_APP_SECRET); 
....
}
....
}

You should explicitly specify a context class loader. For example: Thread.setContextClassLoader(getClass().getClassLoader());

我已经尝试过这个解决方案:dropboxSync出错:findlibrary返回null
但它对我不起作用.
所以请不要将此问题标记为重复.

非常感谢任何帮助,谢谢.
