这是我的Android代码。

@Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 

     if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) { 
      Uri filePath = data.getData(); 
      try { 
       //Getting the Bitmap from Gallery 
       bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath); 
       //Setting the Bitmap to ImageView 
       btnCamera.setImageBitmap(bitmap); 

      } catch (IOException e) { 
       e.printStackTrace(); 
      } 
     } 
    } 

    private void dispatchTakePictureIntent() { 
     Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
     if (takePictureIntent.resolveActivity(getPackageManager()) != null) { 
      startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE); 
     } 
    } 

    private void showFileChooser() { 
     Intent intent = new Intent(); 
     intent.setType("image/*"); 
     intent.setAction(Intent.ACTION_GET_CONTENT); 
     startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST); 
    } 

    public String getStringImage(Bitmap bmp){ 
     ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
     bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos); 
     byte[] imageBytes = baos.toByteArray(); 
     String encodedImage = Base64.encodeToString(imageBytes, Base64.DEFAULT); 
     return encodedImage; 
    } 

    private void uploadImage(){ 

     JSONObject js = new JSONObject(); 
     String name = txtDesc.getText().toString(); 
     try{ 
      js.put("image", getStringImage(bitmap)); 
      js.put("name", name); 

      Log.e("js", js.toString()); 
      JsonObjectRequest jsonObjReq = new JsonObjectRequest(
        Request.Method.POST,UPLOAD_URL, js, 
        new Response.Listener<JSONObject>() { 
         @Override 
         public void onResponse(JSONObject response) { 
          Log.d(TAG, response.toString()); 
          Toast.makeText(ctx, "Success", Toast.LENGTH_LONG).show(); 

          try{ 
           String strSuccess = response.getString("code"); 
           Log.d(TAG, strSuccess); 
          } catch (JSONException e) 
          { 
           Log.d(TAG, e.toString()); 
          } 



         } 
        }, new Response.ErrorListener() { 

       @Override 
       public void onErrorResponse(VolleyError error) { 
        VolleyLog.d(TAG, "Error: " + error.getMessage()); 

        Toast.makeText(ctx, "Failed", Toast.LENGTH_LONG).show(); 

       } 
      }); 

      VolleyRequestQueue.getInstance(ctx).addToRequestQueue(jsonObjReq); 
     } catch (JSONException e) 
     { 
      Log.e(TAG, e.toString()); 
     } 
    }

PHP代码。

<?php 
header('Content-type: application/json'); 

require_once 'db_config.php'; 
$json = file_get_contents('php://input'); 
$data = json_decode($json); 

$image= $data->image; 
$name = $data->name; 


$actualpath = "http://46.101.2.231/FootballGroundGuide/stadium_images/$name" ; 


file_put_contents($actualpath,base64_decode($image)); 
echo "Successfully Uploaded"; 




?>

尝试检查'file_put_contents'的[返回值]（http://php.net/manual/en/function.file-put-contents.php#refsect1-function.file-put-contents-returnvalues）。 *这个函数返回写入文件的字节数，或者失败时返回FALSE。* – zwcloud

开始说SUCCESS导致我相信这是我的PHP的问题。 – xiimoss

file_put_contents方法将false返回给应用程序@zwcloud – xiimoss

修复了这个问题。当我只需要使用“文件夹名称/文件名”时正在使用完整的URL。
