I have built an apk file using ionic cordova build android. And I have opened that app using Genymotion emulator. When I opened the app, it starts and displays the splash screen. After that a white screen appears forever (I can close the app. But when I start that again, same thing happens).
我在 android studio 控制台中捕获了错误.
I have captured the error in the android studio console.
他们来了，
然后我在那个 apk 中打开了 main.js 文件.在第 40 行，我找到了这段代码.
And then I have opened the main.js file in that apk. In line 40, I have found this code.
然后我浏览了 pages (./pages/scanner/scanner.ts) 文件夹中的scanner.ts.我没有发现任何问题.当我使用 cordova run browser 运行它时它可以工作.
Then I browsed the scanner.ts in pages (./pages/scanner/scanner.ts) folder.
I did not find anything wrong. It works when I run that using cordova run browser.

推荐答案
将tsconfig.json中的target值由es6改为es5 有效.
例如.target":es6" >>> target":es5"
Changing the target value in the tsconfig.json from es6 to es5 has worked.
Eg. "target": "es6" >>> "target": "es5"
注意:除非您明确声明，否则此问题不会自动发生在项目中.
Note: This problem will not automatically happen to the project unless you declare that explicitly.
