问题描述
-
下面是code，我现在用：
Here is the code that i am using :
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);
}
}
和这里的错误：

我应该怎么办？
推荐答案
林不知道这是正确的解决方案。
im not sure this is right solution
C $ C>在你的依赖球衣，JSON 模块/类路径。
according to Jersey deps you need to have jersey-json module in your dependencies/classpath.
如果它的名字是libitv.so该库将被识别，并放置在库\\ armeabi目录中的应用程序目录，apk文件是建立之前。
The library will be recognised if its name is libitv.so and is placed in libs\armeabi directory in your application directory, before the .apk is built.
有时，当库不是完全复制（部分复制），由于一些系统发出的部分库也不会被认可。
Sometimes when the library is not copied completely(partial copy), due to some system issues the partial library too will not be recognized.

更新：
java.lang.ExceptionInInitializerError
产生的原因： java.lang.UnsatisfiedLinkError中：图书馆jniavutil没有找到
Caused by: java.lang.UnsatisfiedLinkError: Library jniavutil not found
您除了需要libsndfile安装libFLAC。
您可以使用libFLAC你使用任何方法可能安装
得到libsndfile安装...
You need to install libFLAC in addition to libsndfile. You can probably install libFLAC using whatever method you used to get libsndfile installed...
您已经错过了从DDMS日志importent位。寻找一个
行，其中包括所造成的和/或包括多个异常
日志，所以我们可以看看它。
You have missed out the importent bits from the ddms log. Look for a line that includes "caused by" and/or include more of the exception log so we can have a look at it.
您已经与$ C $启用覆盖CPRO编译。将其关闭。
You've compiled with CodePro coverage enabled. Turn it off.
其实这是为了克服这个例外，我们正面临着ADT 17，你必须把你的jar文件到库问题文件夹
Actually this is the problem we are facing with ADT 17 you have to put your jar file into libs folder in order to overcome this exception
在你的项目，所以右键 - >创建一个名称的文件夹的库
so right click on your project -->create a folder with name libs
，然后按照这个步骤
right click (on libs folder) -->import-->File System-->browse to select your jar file and hit finish and run you project.
之后
right click on the project --> Built Path-->java built path-->add jars select your jar file from your libs folder
如果这也没有重建工作
一切（包括数据），它会工作。
if this also didn't work rebuilding everything (included data), and it will works.
