Visual Studio aar libraries

Elements Silver
1

Hi all,

i try to reference google play services to VS project but i have two issues

  1. when i try to reference the aar library in Android sdk directory structure the build stops with error that cannot find library (in case i put aar in to the root project directory this error disappears)
  2. but for the next error i was not able to find any workaround
    error JE20: Could not load referenced Java archive “classes.jar”: Invalid reference

Any idea how to reference aar libraries in Visual Studil Swift project ?

Thank you
Jan

Sorry for the delayed response. Is this with 8.3 or the 8.4 beta?

we made significant changes and improvements to the reference tool chain for 8.4, so if you’re currently on 8.3, i recommend trying the latest, before we investigate further. In general, just adding the .aar as reference should “work”.

Could you sand me the link fo 8.4 beta.

Thank you

Marc,

now i have tested latest beta and I receive this exception during build
process

C:\Users\radl\OneDrive\Dokumenty\Visual Studio
2015\Projects\org.me.androidapplication1\org.me.androidapplication1\Android\aarrefs\play-services-maps-9.6.1\res\values\values.xml(3,1):
error Android: Attribute “mapType” already defined with incompatible format.

Original attribute defined here.

Any idea ?

Hmm, sounds like for some reason two versions of the values.xml file are being processed, one from Android\aarrefs (where does that come from?) and one from \obj\Debug\Android\aar\ (that’s where we un-archive the .aar’s to during build.

Could the first one bet a leftover from an earlier version? Did you put stuff in \Android\aarrefs\ yourself? what happens if you delete that folder?

Well I remove the wrong directory and now I receive

error JE20: Could not load referenced Java archive “classes.jar”: Invalid
reference

Hmm. Is this for an Android app or a plain Java app? do you have classes or android as reference in your project? can you send me the project?

Hi Marc,

I’m so sorry I disturb you, but did you find the reason of compilation
error ?

Thank you

Jan

sources ?

Thank you

that’s A LOT of reference to classes.jar, which does fit exist for Android. where did this come from?

If i remove those, i’m down to

public override func onCreate(savedInstanceState: Bundle!) { // E178 Cannot find a suitable method in the base class to override with signature "onCreate(# savedInstanceState: Bundle!)"
															 // N12 Possible match: onCreate(_ Bundle!)

which needs an underscore for Swift 3, e.g.:

public override func onCreate(_ savedInstanceState: Bundle!) {

and after that, all builds (and fails on me not having your keystore; expected).
