Question

我有一个弹出的带有多个链接库的本机应用程序，该应用程序无法在Android中运行（在iOS中可以运行）。依赖图加载到100％，有时会在模拟器上显示启动屏幕，但是当模拟器尝试加载js包时，它立即崩溃。

package.json中的相关软件包

Answer 1

我从未从事过React-native项目。但是我认为MainActivity.java中有问题。

在Android中，通常我们在super.onCreate()之后启动初始UI代码。也许您可以在调用super.onCreate

之后再调用SplashScreen.show

super.onCreate(savedInstanceState);
SplashScreen.show(this);  // here

尽管加载了“依赖图”，但带有链接库的React-Native 0.60+仍未运行
