我是初学，代码也是抄百度的例子，但是执行到HttpResponse response = df.execute(request);的时候就直至跳到catch （Exception e），我加了权限，模拟器也换过了几个了，一直都是异常，求大神解答
public class PostActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button b = (Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
HttpGet request = new HttpGet("http://10.0.2.2/android.php?name=Neeke");
try {
DefaultHttpClient df=new DefaultHttpClient();
df.getParams().setParameter(CoreConnectionPNames.CONNECTION_TIMEOUT, 10000);
df.getParams().setParameter(CoreConnectionPNames.SO_TIMEOUT, 10000);
request.addHeader("Accept-Language", "en");
HttpResponse response = df.execute(request);
/*if(response.getStatusLine().getStatusCode() == 200){
String result = EntityUtils.toString(response.getEntity());
Toast.makeText(PostActivity.this, result, Toast.LENGTH_LONG).show();
}*/
} catch (Exception e) {
Toast.makeText(PostActivity.this, "error", Toast.LENGTH_LONG).show();
e.printStackTrace();
}
}
});
}
}

------解决方案--------------------
你不是说直接跳到catch （Exception e）吗 把这个异常信息贴出来啊
