2.0 NativeScriptActivity.java and NativeScriptApplication.java changes

[sitefinitysteve]

Plugin: https://github.com/sitefinitysteve/nativescript-auth0

Something changed in 2.0 where it seems a tns android replaces the NativeScriptActivity.java and NativeScriptApplication.java files every time...

I have no idea how to implement this plugin reliably, and what's this folder now?

Issue 2 outside of that is I have a BroadcastReciever which is where this auth0 activity shoots it's data.
https://github.com/sitefinitysteve/nativescript-auth0/blob/master/plugin/platforms/android/NativeScriptActivity.java#L100
But how to I get that data from there into here
https://github.com/sitefinitysteve/nativescript-auth0/blob/master/plugin/index.android.js#L13
To return the promise?

[sitefinitysteve]

So I think my looking at the NS source I can create the broadcast reciever though JS which means I don't even need the custom .java activity...

I dont seem to ever HIT my reciever though...

Hi @sitefinitysteve

• ...and what's this folder now? -> F0
• In short, it's a renamed flavor, so we mitigate the "path too long problem". Having said that, we try to hide anything that won't be necessary to the {N} users and that includes the platforms/android folder.

• I have no idea how to implement this plugin ..., But how to I get that data from there into here...
• Pretty soon we'll have an article about the most common scenarios, including how to do a custom Activity and Application. For now you can look at this example to get a better idea how to use the new functionality to create an activity, application or any other application component like broadcast receiver.

[sitefinitysteve]

Why do the activity and application files get overwritten on every tns run? Makes it literally impossible to develop an app because you have to constantly monitor the files to see if they've been replaced.

Seemed okay in 1.7

[Plamen5kov]

Hi @sitefinitysteve,
The logic for these files can be entirely in their javascript counterparts. This means that the user shouldn't have to change anything in the platforms/android folder. There will be a proposal soon that will allow for changed files not to be replaced, but that shouldn't be necessary.
Can you share what scenario, requires you to change the logic of the activity or application in the platforms/android folder?

[sitefinitysteve]

Auth0 plugin :/ works great on ios, but reeeeeally struggling with droid. I would love to not have to touch anything in the platform folder.

Like if i register the reciever in the .java i don't know how to send the result back to a js callback. But if i register the reciever in js, it doesn't seem to hit.

So like this seems okay in 1.7...aside from the inability to get the reciever result back into js

@sitefinitysteve as I see in the sample files provided here and [here](https://github.com/sitefinitysteve/nativescript-auth0/blob/master/plugin/platforms/android/Nat
ativeScriptActivity.java), you're adding logic in the lifecycle callbacks. You can achieve the same result if you move the logic surrounded by // AUTH0 START and // AUTH0 END to javascript.
The modules provide all application and activity callbacks you're using.

[sitefinitysteve]

@Plamen5kov In your opinion then, I don't even NEED the custom java stuff?

[sitefinitysteve]

Going on that, this is what I'm rockin right now...

But throws
The application crashed because of an uncaught exception. You can look at "stackTrace" or "nativeException" for more detailed information about the exception.

Which makes me think the interface is important because I'm not sure how to impliment in JS
https://github.com/sitefinitysteve/nativescript-auth0/blob/master/plugin/platforms/android/NativeScriptApplication.java#L18

[Plamen5kov]

Hi @sitefinitysteve,
Currently there is no way of implementing the interface on the application, you can only implement the interface but not a class that implements an interface. If you like, you can open a new issue.

Thank you for trying to implement everything in javascript, it was very helpful to me and the team to know concrete examples and scenarios in order to better NativeScript.

[sitefinitysteve]

@Plamen5kov So where do I go from here with these issues?

I suppose the main two are even if I can replace the platform/android/*/NativeScriptAppliction\Activity.java files directly, they just get constantly overwritten.

...and I dont seem to have any way to get the receiver to receive the data in JS so I can resolve my promise.

The entire process on the droid side has just been bumming me out for months, I feel like I'm just never gonna be able to get this Auth0 android-side plugin off the ground, where it works great on iOS.

[Plamen5kov]

Hi @sitefinitysteve,
We think on implementing a solution where we will be able to know what files are not to be overridden. This way you'll be able to override the NativeScriptApplication and Activity files, as you have done up till now, until a more general solution is found.
Unfortunately this fix will probably come with the next release.

[sitefinitysteve]

There's no unfortunately in having to wait a few months, as long as the platform gets it!

Sidenote this popped up today as well

...we need working reliable oauth in {N}. Can you use this plugin to try to solve this ticket issue?

[valentinstoychev]

@Plamen5kov is this related to #283

[Plamen5kov]

No @valentinstoychev, this is a separate issue.
