Seems it's something wrong with your react code

[xiaozhicheng]

the white screen still has long time

[markzhai]

please check your adb log with TAG MrReactActivity to see if it's using cached view

[xiaozhicheng]

aslo,it give me the error: The specified child already has a parent. You must call removeView() on the child's parent first.

[markzhai]

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

    if (mReactRootView != null) {
        mReactRootView.unmountReactApplication();
        mReactRootView = null;
        ReactPreLoader.onDestroy(getReactInfo());
    }

// getReactNativeHost().clear(); }

the view should be removed when activity destroyed, please check if your activity get destroyed

[xiaozhicheng]

Are you Chinese? 我是退出去后马上又进去报这个错误

[markzhai]

请贴下你的ReactActivity代码，看看你的onDestroy是否正确执行了，看上去是没有执行基类的onDestroy

[xiaozhicheng]

onDestroy调用问题，就是你退出页面，ondestory不会立即执行，再次进入又开始执行onCreate了，觉得你那个removeView在按back按钮之前调用

@xiaozhicheng

dependencies { compile "com.github.markzhai:react-native-preloader:0.32.0" }

试试看这个
