Android 开发之 HttpClient Class can not find 之解决办法
转载,原文出处: http://blog.zhourunsheng.com/2012/03/android-%E5%BC%80%E5%8F%91%E4%B9%8B-httpclient-class-can-not-find-%E4%B9%8B%E8%A7%A3%E5%86%B3%E5%8A%9E%E6%B3%95/
相信大家在开发 Android 的过程中遇到过这么一种情况,那就是 “Could not find class 'org.apache.commons.httpclient.HttpClient'”。
尤其是在 eclipse 的插件ADT升级之后,很容易出现该问题,昨天Google放出了ADT的升级包,然后我也就升级了一下开发环境,没想到前天还运行好好的程序,今天突然就不会工作了,检查log发现,HttpClient无法找到,但是在普通的Java运行环境下就可以正常运行。
因为Apache的HttpClient开发包,Google自己也定制了一份,已经内置到开发环境中了,所以我们如果使用纯粹的Apache原生态的HttpClient开发包就可能出现冲突的问题,每当Google升级ADT之后,说不定程序就Over了。
下面是自己写的基于Google的一个简单的代码
package mars.httpclienttest; import android.app.Activity; import android.content.Intent; import android.os.Bundle; // import org.apache.http.HttpResponse; import org.apache.http.client.HttpClient; import org.apache.http.client.methods.HttpGet; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.util.EntityUtils; import android.util.Log; import java.net.URL; // import android.widget.Button; import android.view.View; import android.view.View.OnClickListener; import android.widget.TextView; public class HttpActivity extends Activity{ // private String strURL = "xxxxxxxx"; // private Button loginButton = null; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.main); // TODO Auto-generated method stub HttpGet objGet = new HttpGet(strURL); HttpClient client = new DefaultHttpClient(); try { HttpResponse response = client.execute(objGet); System.out.println(EntityUtils.toString(response.getEntity())); } catch (Exception e) { Log.e("httpGet", e.getMessage()); } } }
