當使用澤西在Android應用寧靜的API，我得到這個錯誤：

Question

1. 這裏是我使用的代碼：

   import android.os.Bundle; 
   import android.support.v4.app.Fragment; 
   import android.view.LayoutInflater; 
   import android.view.View; 
   import android.view.ViewGroup; 
   import java.io.File; 
   import java.io.IOException; 
   import java.util.logging.Logger; 
   import java.io.FileInputStream; 
   import java.io.FileNotFoundException; 
   import org.apache.commons.codec.binary.Base64; 
   
   
   public class Fragment_2 extends Fragment { 
   static Logger logger = Logger.getLogger(Fragment_2.class.getSimpleName()); 
   
   public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){ 
   
   new Thread(new Runnable() { 
   
       public void run() { 
   
        try { 
         String base64 = null; 
          String imageDataString2 = null; 
          File file = new File("/mnt/sdcard/DCIM/Camera/2013-03-27 00.22.48.jpg"); 
   
          try { 
            // Reading a Image file from file system 
            FileInputStream imageInFile = new FileInputStream(file); 
            byte imageData[] = new byte[(int) file.length()]; 
            imageInFile.read(imageData); 
   
            // Converting Image byte array into Base64 String 
            String imageDataString = new String(Base64.encodeBase64(imageData)); 
   
            imageDataString2 = imageDataString.replace("_", "/"); 
            imageDataString2 = imageDataString2.replace("-", "+"); 
   
            System.out.println(imageDataString2); 
            base64 = imageDataString2; 
            System.out.println("Image Successfully Manipulated!"); 
           } catch (FileNotFoundException e) { 
            System.out.println("Image not found" + e); 
           } catch (IOException ioe) { 
            System.out.println("Exception while reading the Image " + ioe); 
           }       
           ClientConfig config = new DefaultClientConfig(); 
           Client client = Client.create(config); 
           WebResource service = client.resource(UriBuilder.fromUri("http://xxxxxx:8080/api").build());//change it to the latest URL 
   
           Form f = new Form();     
           f.add("img",base64);  
   
           String s = service.post(String.class, f); 
   
        } catch (Exception e) { 
   
        }   
       } 
   
   }).start();       
   return inflater.inflate(R.layout.fragment_2, container, false); 
   } 
   
   } 
   

，這裏是錯誤：

我該怎麼辦？

Answer 1

林不知道這是正確的解決方案，根據你需要有jersey-json模塊在你的依賴/ classpath中Jersey deps

。

如果庫的名稱爲libitv.so，並且在建立.apk之前將其放入應用程序目錄中的libs \ armeabi目錄中，它將被識別。

有時，當庫沒有完全複製（部分複製）時，由於某些系統問題，部分庫也無法識別。

欲瞭解更多詳情，請參閱here

試試這個link有一些解決方案

更新：

java.lang.ExceptionInInitializerError 

產生的原因：java.lang.UnsatisfiedLinkError:圖書館jniavutil沒有找到

您需要安裝除libsndfil外還有libFLAC即 您可以使用您使用 得到libsndfile安裝

您已經錯過了從DDMS日誌importent位任何方法... libFLAC可能安裝。查找 行，其中包含「由......引起」和/或包含更多異常 日誌，以便我們可以查看它。

您已啓用CodePro覆蓋進行編譯。把它關掉。

其實這是我們面臨與ADT 17，你必須把你的jar文件到庫爲了克服這個異常

所以右鍵點擊你的項目文件夾中的問題 - >創建一個文件夾名庫

，並按照該步驟中

right click (on libs folder) -->import-->File System-->browse to select your jar file and hit finish and run you project. 

之後

right click on the project --> Built Path-->java built path-->add jars select your jar file from your libs folder 

如果這也沒有工作重建 一切（包括數據），它會起作用。
