【报Bug】安卓打开小程序，有几率页面白屏并报错: Uncaught TypeError: Cannot read property 'setStatusBarStyle' of undefined

示例代码：

点击按钮加载初始化 uni-app sdk, 之后打开小程序。以下是基于官方demo的打开小程序的代码片段，改动点为延迟初始化 uni-app sdk:

button1.setOnClickListener(new View.OnClickListener() {  
    @Override  
    public void onClick(View view) {  
        try {  
            // 延迟加载 Uni-App sdk, 这里是点击 button1 的时候，在打开 uni-app 前初始化 sdk  
            initUniAppSDK();  
            if (!DCUniMPSDK.getInstance().isInitialize()) {  
                Toast.makeText(mContext, "uni-app sdk 未初始化", Toast.LENGTH_SHORT).show();  
                return;  
            }  
            UniMPOpenConfiguration uniMPOpenConfiguration = new UniMPOpenConfiguration();  
            // 为了方便观察白屏现象，不设置 SplashView  
            // uniMPOpenConfiguration.splashClass = MySplashView.class;  
            uniMPOpenConfiguration.extraData.put("darkmode", "light");  
            IUniMP uniMP = DCUniMPSDK.getInstance().openUniMP(mContext,"__UNI__F743940", uniMPOpenConfiguration);  
            mUniMPCaches.put(uniMP.getAppid(), uniMP);  
        } catch (Exception e) {  
            e.printStackTrace();  
        }  
    }  
});

延迟加载小程序代码片段，以下是官方 demo 的初始化 uni-sdk 的代码，在此基础上的改动点 setEnableBackground 改为 false:

public void initUniAppSDK() {  
    if (DCUniMPSDK.getInstance().isInitialize()) {  
        Log.i("unimp","uni-app sdk 已初始化过，不再初始化");  
        return;  
    }  

    try {  
        WXSDKEngine.registerModule("TestModule", TestModule.class);  
        WXSDKEngine.registerComponent("myText", TestText.class);  
    } catch (Exception e) {  
        e.printStackTrace();  
    }  
    //初始化 uni小程序SDK ----start----------  
    MenuActionSheetItem item = new MenuActionSheetItem("关于", "gy");  

    MenuActionSheetItem item1 = new MenuActionSheetItem("获取当前页面url", "hqdqym");  
    MenuActionSheetItem item2 = new MenuActionSheetItem("跳转到宿主原生测试页面", "gotoTestPage");  
    List<MenuActionSheetItem> sheetItems = new ArrayList<>();  
    sheetItems.add(item);  
    sheetItems.add(item1);  
    sheetItems.add(item2);  
    Log.i("unimp","onCreate----");  
    DCSDKInitConfig config = new DCSDKInitConfig.Builder()  
            .setCapsule(false)  
            .setMenuDefFontSize("16px")  
            .setMenuDefFontColor("#ff00ff")  
            .setMenuDefFontWeight("normal")  
            .setMenuActionSheetItems(sheetItems)  
            // 改动点: 禁用在后台运行  
            .setEnableBackground(false)  
            .setUniMPFromRecents(false)  
            .build();  
    DCUniMPSDK.getInstance().initialize(this, config, new IDCUniMPPreInitCallback() {  
        @Override  
        public void onInitFinished(boolean b) {  
            Log.d("unimpaa","onInitFinished----"+b);  
        }  
    });  

    //初始化 uni小程序SDK ----end----------  
}

操作步骤：

运行附件中的代码到手机上

步骤1. 进入 App，进入步骤2
步骤2. 点击第一个按钮button1，进入小程序，看是否白屏，如果没有白屏，则进入步骤3，如果有白屏，则复现成功
步骤3. 退出app，进入步骤1

预期结果：

预期结果，在 uni-app sdk 初始化成功（DCUniMPSDK.getInstance().isInitialize() 为 true）之后，打开uni小程序不应该出现白屏，实际是有几率出现白屏

实际结果：

在在 uni-app sdk 初始化成功（DCUniMPSDK.getInstance().isInitialize() 为 true）之后，打开 uni小程序，有几率出现白屏，此时logcat的报错信息为：
