When using tns run <platform> app is built and installed many times without change is made (android only)

[Natalia-Hristova]

After running sdk examples for android then for ios, in android only - the app is built and installed over and over again without making any change in the app or interacting with it.

NOTE: If first ios is run then android - everything's fine.

Here's the app - https://github.com/telerik/nativescript-ui-samples/tree/master

1. Run the app for android - tns run android
2. Then in another terminal tab run the app for ios - tns run ios

This issue comes with NativeScript CLI 2.5.0.

My steps:

git clone git@github.com:telerik/nativescript-ui-samples.git
cd nativescript-ui-samples/sdk
tns update 2.5.0
tns run android
tns run ios # in another terminal

I don't manage to reproduce the issue with the steps above.

Then, if I execute:

rm -frv platforms
tns run android
tns run ios # in another terminal

I manage to reproduce the issue.

My guess is that platform adding, which happens on the tns run ios (installing iOS runtime package to node_modules and removing it), triggers a loop of rebuilds for every file the package contains.

Workaround:

Execute tns run <platform> --no-watch|--justlaunch.

We need to figure out what behavior we want to support before we can do any work in a particular direction.

[Plamen5kov]

We should make the run command behave the same way, livesync did: tns run should try to livesync all platforms and a <platform> parameter should be optional.
