Please, provide the details below:

Did you verify this is a real problem by searching Stack Overflow and the other open issues in this repo?

Yes.

Tell us about the problem

Recently cleaned out my project directory and now I'm having these build issues:

:asbg:generateInterfaceNamesList
:asbg:traverseJsFiles
:asbg:runAstParser
Running full build
finished with reading lines with js files
:asbg:generateBindings
java.lang.IllegalArgumentException: clazz is null

which results in the app crashing on launch.

Did the error happen while the app was being constructed? (buildtime error)

Yes. I tried doing --log trace but it flooded my terminal memory and couldn't capture it 😦
The app builds and deploys to device no problem.

Did the error happen while the app was executing? (runtime error)

Yes,

Not sure what all that means 🤐

Please tell us how to recreate the issue in as much detail as possible.

Creating a new blank project does not produce this error; but I am extending the activity:

@JavaProxy('com.tns.NativeScriptActivity')
class Activity extends android.app.Activity {}

I'm in the midst of trial and error removing parts of the app trying to get it to build. lol

[petekanev]

@roblav96 I was unable to make a fresh app crash using the aforementioned versions when extending a native activity.
Please paste the content of your root-level package.json here, also, navigate to \platforms\android\build-tools\android-static-binding-generator\bindings.txt and attach the file, thank you.

[roblav96]

@Pip3r4o I too am unable to reproduce extending activity with a fresh app as well. Very strange :O

Also bindings.txt file does not exist in that directory nor any directory in platforms\android.

[petekanev]

@roblav96 it is generated on build, if :asbg:runAstParser has passed, there should be bindings.txt somewhere in platforms/androd

[roblav96]

@Pip3r4o I figured out the cause, bradmartin/nativescript-snackbar#16

[petekanev]

@roblav96 responded in the issue you linked above, I believe to be a missing dependency to a particular version (22.2.0) of the design library.

[petekanev]

If the static-binding-generator throws an exception, it will not generate any pending classes, hence why there isn't a NativeScriptActivity at runtime. I am unable to cause the binding generator to crash build-time, so I am asking for your help.

Edit: the crash was reproduced successfully and a fix is underway.
