当我在安卓6或7和安卓Oreo(8.1)上运行应用程序时,我遇到了这个错误

复制步骤

相关代码

async revisa_sincro(){<。。。。。代码…>}

预期行为

所以,真正的问题是这个[async]关键字停止应用程序,并向我显示白色屏幕和如果我删除所有异步代码,应用程序运行正常。但我真的需要这个异步!!!

有两件事需要检查。。。

ECMAScript版本

您可以使用TypeScript编译器以不同的ECMAScript版本为目标,因此请确保以运行时使用的版本为目标。i、 e.在tsconfig.json文件中:

"target": "ES5"

如果您已经完成了上述操作,但仍然存在问题,那么这通常是由加载TypeScript文件引起的 .ts 这是运行时的意外,而不是JavaScript .js
