ONSTART打开异步箱的错误

在我的应用程序中，在应用程序的每个开始，我都想执行PHP脚本并相应地加载应用程序。因此，我创建了一个静态布尔值

boolean firstRun = false;

在我的Onstart中，我添加了以下代码：

// If images need to be downloaded, call SProgressAsyncTask class
    public void onStart() {
    super.onStart();
    if (firstRun) {
        sat = new SProgressAsyncTask(this);
        sat.execute("");
        firstRun = false;
    }
}

在索尼的朋友的设备上，它可以完美地工作，即以上代码仅执行一次，即启动应用程序。在我的Sony Xperia P上，每次应用程序都进入此主屏幕时，上述代码都会执行。当将firstrun变成错误时，为什么上述代码每次返回此活动时都会运行。我尝试在设备上调试，并收到以下错误：

我更改了sprogressasynctask类，而不是传递活动通过上下文-getApplicationContext（），但这使情况更糟。

任何人都可以帮我知道，为什么（firstrun）每次执行而不是仅执行一次。

btw，mine＆amp;我的Firend设备都只有冰淇淋OS。

上午在这个阶段被束缚在5-6天之内，任何帮助都是非常感谢的。请帮助我摆脱此错误。
