我正在通过WIFI向服务器发送信息,一切都很好.现在我也想将信息发送到带有移动数据的服务器,我不知道为什么只适用于WIFI,移动数据流程异常无法连接到服务器.

这是移动数据失败的部分; 与WIFI完美结合:

int length=values.length();
    HttpParams httpParams = new BasicHttpParams();
    HttpConnectionParams.setConnectionTimeout(httpParams,9000);
    HttpConnectionParams.setSoTimeout(httpParams, 9000);

    HttpClient client = new DefaultHttpClient(httpParams);

    String url = saveData+"?Length="+length+"&Table="+temp;        
    HttpPost request = new HttpPost(url);
    request.setEntity(new ByteArrayEntity(values.toString().getBytes("UTF8")));        
    request.setHeader("json", values.toString());
    HttpResponse response = client.execute(request);
    HttpEntity entity = response.getEntity();
    // If the response does not enclose an entity, there is no need
    Log.d("test 7","test 7 last");
    if (entity != null) {
        InputStream instream = entity.getContent();
        String result =  RestClient.convertStreamToString(instream);
        Log.d("here",""+result);
        if(result.equals("success")&& ReadyOff==false){
            Ready=true;
        }else{
            Ready=false;
            ReadyOff=true;
        }
        Log.d("sent","valor de ready"+Ready); …

我想用相机拍摄图像并将其保存到图片文件夹中...我唯一无法解决的问题是为什么我的图像以小尺寸保存...

Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(i, TAKE_PICTURE);

protected void onActivityResult(int requestCode, int resultCode, Intent imageReturned) {
    super.onActivityResult(requestCode, resultCode, imageReturned);

    switch(requestCode) {
        case TAKE_PICTURE:
            if(resultCode == RESULT_OK)
            { 
                ByteArrayOutputStream bytes = new ByteArrayOutputStream();
                photo.compress(Bitmap.CompressFormat.PNG, 100, bytes);                  

                File f = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+ File.separator + "test3.png");
                try {
                    f.createNewFile();
                    //write the bytes in file
                     FileOutputStream fo = new FileOutputStream(f);
                     fo.write(bytes.toByteArray());
                     fo.flush();
                     // remember close de FileOutput
                     fo.close();
                } catch (IOException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }    
            }
    }
}
