これが私が使用しているコードです:
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); } }
ここにエラーがあります:

私は何をすべきか?
