我试图制作一个简单的Android应用程序，它在屏幕上显示一个简单的字符串，来自实际网址上的php脚本。不幸的是，我一直得到这个经典的信息＆＃34;不幸的是，你好已经停止＆＃34;在尝试了很多方法之后。
这是myActivity.java：
package com.example.scoelli.hello;
import ...
public class MyActivity extends Activity {
TextView txtHelloWorld;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
txtHelloWorld = (TextView) findViewById(R.id.txthelloworld);
new ConnectTask().execute();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.my, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
private class ConnectTask extends AsyncTask<Void, Void, HttpResponse> {
protected HttpResponse doInBackground(Void... params) {
String url = "http://www.scoelli.ewwoconsulting.com/hello/";
HttpClient httpclient = new DefaultHttpClient();
try {
HttpGet request = new HttpGet(new URI(url));
request.addHeader("User-Agent", "Android");
HttpResponse response = httpclient.execute(request);
return response;
}catch (URISyntaxException e1) {
e1.printStackTrace();
} catch (IOException ioe){
ioe.printStackTrace();
}
return null;
}
protected void onPostExecute(HttpResponse result) {
String resultado = "NOO";
StatusLine statusLine = result.getStatusLine();
try {
if (statusLine.getStatusCode() == HttpStatus.SC_OK) {
ByteArrayOutputStream out = new ByteArrayOutputStream();
result.getEntity().writeTo(out);
out.close();
resultado = out.toString();
}
} catch (IOException ioe){
ioe.printStackTrace();
}
txtHelloWorld.setText(resultado);
}
}
}
这是我的PHP脚本：
<?php
namespace Controller;
Class Hello
{
static function World()
{
echo "Hola Mundo!";
}
}
?>
我有一个调用静态函数World的控制器;我知道php有效。
除非我使用Android Studio，否则我不知道是否有任何更改。
这是Logcat：

当您在主线程中进行网络访问时，您的应用会因NetworkOnMainThreadExeption而崩溃。将您的http客户端代码放在AsyncTask或线程中，并在清单中请求Internet权限。例外将在您的logcat中。但你没有张贴......

您需要在PHP中创建一个API（REST），您可以从应用程序中调用它。
使用库来帮助处理异步回调对此非常有帮助。
这是我经常使用的那个：
LoopJ's Async HTTP Callback Library
这将处理GET和POST请求，具有许多很酷的功能，如自定义超时，JSON格式，onSuccess（）和onFailure（）方法等。这个库也有很多工作示例。我已经在我的所有应用程序中使用它并且还没有任何问题！
希望这有帮助。
