Android Question AR Library Compilation ERRORS (requires --min-sdk-version >= 26)

[walterf25]

Hi All, i'm trying to play around wrapping some parts of Google's ARCore Library, however i keep getting the following error, i've seen this before but i'm not sure how I was able to get rid of this error, does anyone have ant suggestions, I have been going at this for almost an entire day without any success, i have copied both the Jar and .aar files to the additional libraries folder so i'm really not sure at this point what the issue could be.

The error is the following:

I will really appreciate if someone could shed some light on this problem, i really would like to wrap the ArSceneView View at and the ArSceneFragment part of this library.

Thanks in advance, hope i can get some answers soon.

In the manifest file:

<uses-sdk android:minSdkVersion="21" android:targetSdkVersion="26"/>

Try changing the first part (minSDKversion) to "26" (as described in the error message).

Then see what happens...

Also, this post seems to discuss the "invokedynamic requires" issue in that the AR library may have to be "desugared" using the tool on that page:

As written above it needs to be desugared: desugar - fix the "invokedynamic requires" error

The error is the following

the solution posted will probably not help at all as AR Apps needs to be a InstantApp. I mean if google does not changed this requirement in the meantime...
