圖片上傳到php服務器android

Question

我正在嘗試將圖像上傳到服務器端目錄。這是我的代碼。當我單擊提交按鈕時，它不是上傳圖像。LogCat中沒有任何錯誤。

mBut.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View arg0) {
        String selectedPath = "file://storage/emulated/0/Pictures/Usage Tracker/IMG_20150916_161450.jpg";
        try{

            File file=new File(selectedPath);

            RequestParams params = new RequestParams();
            params.put("uploadedfile",file);
            AsyncHttpClient client = new AsyncHttpClient();
            client.post("http://example.com/utracker/webservices/upload_picture.php",  params, new AsyncHttpResponseHandler() {

                public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {

                    String s=new String(responseBody);
                    if(s.contentEquals("Success")){                
                        Toast.makeText(MainActivity.this, 
                                       "You Have Successfully Uploaded Your Image To Our Server", 
                                       Toast.LENGTH_LONG).show();
                    }
                }

                public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {

                }
            });

        }
        catch (Exception e)
        {             
        }
    }
}

PHP腳本

<?php
    $target_path = "../uploads/";
    $target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
    if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
        //echo "The file ".  basename( $_FILES['uploadedfile']['name'])." has been uploaded";
        echo "Success";
    } else{
        echo "There was an error uploading the file, please try again!";
    }
?>

您無法通過在echo中打印來獲取圖像上傳的成功或失敗，您必須將json編碼的響應返回給android，然后檢查它是成功還是失敗

        if(mysql_num_rows($res) > 0) {

            $response["success"] = 1;
            $response["message"] = "Success";
            echo json_encode($response);
         }
        else{
            $response["success"] = 0;
            $response["message"] = "Failure";
            echo json_encode($response);
            }
