[FR] replace app instead of deleting on android

[farfromrefug]

I am working with nativescript on Android with livesync (using tns 4.0.0-2018-01-23-10431)
Depending on the change i make, the app requires to be re installed.
To do that nativescript first delete the app then install it again.
This is an issue in dev because you loose all the app settings. So if you are working on a deep workflow of the app, you have to do all over again pretty often.

Couldn't the app be only replace with adb install -r ?

Thanks

@farfromrefug the app is installed exactly in the way you have described

@Plamen5kov sometimes the cli actually uninstall the app first. I even see a log saying it.
What about this?

@Plamen5kov @rosen-vladimirov i still see this.
Especially i see this when running the app in production. Whenever i run tns run android --release ... the app is alwasy uninstalled / installed.
This is bad for for 2 reasons:

• i lose the app current settings and data
• it prevent me from doing some correct time profiling. At the beginning of my app there are permissions requests which delay the app loading. Because of that issue permissions are requested every time, slowing down and making my profiling random (because it something that i need to do manually as quickly as possible).

Same issue here. I'm not able to keep a single file after app upgrade in both, development (debug) and production (build release). Any workaround ??

[hgc2002]

There is one workaround that is changing the NS code to avoid deleting all before any new install (I read about that some time ago but I could not find the reference to add it here).
Another one is to use external storage. That's the one I'm using right now and it goes fine.
