代码：

public class UploadAudioDemo extends Activity { 

    private static final int SELECT_IMAGE = 1, SELECT_AUDIO = 2; 
    String selectedPath = ""; 
    Button ImageBtn, AudioBtn; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     ImageBtn = (Button)findViewById(R.id.image_btn); 
     AudioBtn = (Button)findViewById(R.id.audio_btn); 
     ImageBtn.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       Intent intent = new Intent(); 
       intent.setType("image/*"); 
       intent.setAction(Intent.ACTION_GET_CONTENT); 
       startActivityForResult(Intent.createChooser(intent,"Select Image"), SELECT_IMAGE); 
      } 
     }); 
     AudioBtn.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       // TODO Auto-generated method stub 
       Intent intent = new Intent(); 
       intent.setType("audio/*"); 
       intent.setAction(Intent.ACTION_GET_CONTENT); 
       startActivityForResult(Intent.createChooser(intent,"Select Audio"), SELECT_AUDIO); 
      } 
     }); 
    }

     try {

我已经等了25-30分钟，但屏幕保持不变，也没有该文件被上传到服务器...

请帮助..

您应该包括以下用途的权限也：

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
