Android file uploading with Apache HTTPClient library -
i have problems import libraries in "libs" folder of android project. tried jersey client , apache http client libraries , both doesn't works.
i have configured manifest file this:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.androidclient" android:versioncode="1" android:versionname="1.0" > <uses-sdk android:minsdkversion="7" android:targetsdkversion="15" /> <uses-permission android:name="android.permission.write_external_storage"/> <uses-permission android:name="android.permission.internet"/> <application android:allowbackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/apptheme" > <activity android:name="com.example.androidclient.mainactivity" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.main" /> <category android:name="android.intent.category.launcher" /> </intent-filter> </activity> </application> </manifest> calling client in main activity:
package com.example.androidclient; import android.os.bundle; import android.os.networkonmainthreadexception; import android.app.activity; import android.view.menu; public class mainactivity extends activity { @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); restclient client = new restclient(); } and restclient class using apache frameworks:
package com.example.androidclient; import java.io.file; import java.io.ioexception; import org.apache.http.httpresponse; import org.apache.http.client.clientprotocolexception; import org.apache.http.client.httpclient; import org.apache.http.client.methods.httppost; import org.apache.http.entity.mime.httpmultipartmode; import org.apache.http.entity.mime.multipartentity; import org.apache.http.entity.mime.content.contentbody; import org.apache.http.entity.mime.content.filebody; import org.apache.http.impl.client.defaulthttpclient; public class restclient { public restclient() { httpclient httpclient = new defaulthttpclient(); httppost httppost = new httppost("http://localhost:8080/restfulimg/rest/file/upload"); file file= new file("http://www.mkyong.com/wp-content/uploads/2009/01/java-project.png"); contentbody fb = new filebody(file, "image/jpeg"); multipartentity entity = new multipartentity( httpmultipartmode.strict); entity.addpart("file", fb); httppost.setentity(entity); httpresponse response = null; try { response = httpclient.execute(httppost); } catch (clientprotocolexception e) { // todo auto-generated catch block e.printstacktrace(); } catch (ioexception e) { // todo auto-generated catch block e.printstacktrace(); } system.out.println("file "+response.tostring()+""+" e stato inviato al server"); } } and log after launching:
