应用程序在将图像上载到服务器时退出

Question

我正在将图像上传到服务器，并在上传后我正在下载该图像以在屏幕上显示。一切正常，但我有一个问题，当我点击上传后选择它退出应用程序的图像并带我到设备主屏幕，然后上传后再下载到它指向该屏幕，时间取决于图像尺寸。谁能告诉我这是什么问题？ 看看我实施的代码：

protected void uploadImageToServer(Bitmap bitmap)
    {
        //Bitmap yourBitmap;
        Bitmap resized = Bitmap.createScaledBitmap(bitmap, 100, 100, true);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();  
        resized.compress(Bitmap.CompressFormat.JPEG, 100, baos);   
        byte[] b = baos.toByteArray(); 
        String encodedImage = Base64.encodeToString(b, Base64.DEFAULT);
        Log.w("encodedImage",encodedImage);

        if(isInternetOn(this)){
            Log.i("UserID",""+mSettings.get_ID());
            btn_Delete_Image.setVisibility(Button.INVISIBLE);
            //  Toast.makeText(this, "webservice not ready", Toast.LENGTH_LONG).show();
            HomeClubTask forgotPaswTask=new HomeClubTask();
            forgotPaswTask.execute(mSettings.get_ID(),encodedImage);
        }else{
            Toast.makeText(this, Constants.NO_NETWORK, Toast.LENGTH_LONG).show();
        }
    }

private class HomeClubTask extends AsyncTask<String, Void, Object> {

        @Override
        protected void onPreExecute() {
            super.onPreExecute();

            dialog.show();
            dialog.setContentView(R.layout.customdialog);
            dialog.setIndeterminate(false);
            dialog.setCancelable(false);
            dialog.setCanceledOnTouchOutside(false);
        }

        @Override

                    SoapObject response = (SoapObject)result;
                    Log.i("My Response",""+response);
                    if(!(response.getProperty("Status").toString().equalsIgnoreCase("anyType{}"))){
                        String value=response.getProperty("Status").toString();

                    }


                }
