Debug an android app

The Android Studio emulator slows down the computer a lot so I can not use it, so to check anything, I have to build the whole app and then upload it to a phone, which in addition to the time it takes, then I can not have information of what happens as if I could have it in a computer browser.

I had found this:

<a href="https://www.joezimjs.com/javascript/how-to-debug-android-chrome-from-your-windows-pc/">https://www.joezimjs.com/javascript/how-to-debug-android-chrome-from-your-windows-pc/</a>[<a href="https://www.joezimjs.com/javascript/how-to-debug-android-chrome-from-your-windows-pc/" target="_blank" title="New Window">^</a>]

That allows you to connect the phone and debug with Chrome, but although my application works perfectly, when I see it from chrome it tells me that it can not find the resource and I can not use it either from the phone or from the browser. Specifically, he tells me that:

/ android_asset / www / # / bookappointments: 1 Failed to load resource: the server responded with a status of 404 (Not Found)

I thought it would be because I made a bundle when building with the webpack, but I tried to build before with ng build --prod --sourceMap = true to have the sourceMap but neither ... I do not know if there is a possibility to build the application with all the files so that instead of being compressed it keeps the whole structure and can debug like this ...
