Android studio 2.2.2 jitpack依赖url未同步和获取依赖于一个或多个Android库但是是一个jar

Question

我使用eclipse将.aar库提取为一个库项目，并在Android studio 2.2.2中使用as子模块（只有一个包含此lib的类jar）。

File f = fileFromDatabase // from database the fileName is india.png
DataInputStream din = new DataInputStream(new FileInputStream(f));
din.readFully(data);
din.close();
String base64 = Base64Utils.toBase64(data);
String[] s = filename.split("\\.");   

base64 = "data:" + "india/png" + ";base64," + base64;
or
base64 = "data:image/png;base64," + base64;

return base64;

clientSide:

 imageService.getImageData(new AsyncCallback() {
    @Override  
     public void onSuccess(String imageData) {    
        Image image = new Image(imageData);    
         Canvas.addChild(image);
         //this Canvas class addItem into com.smartgwt.client.widgets.Window
      }
     @Override 
     public void onFailure(Throwable caught) {

     }
}
client side imageData stirng is <image class="gwt-Image src=sume big string starts with "data:image/png;base64,someSting......>"
