I had this problem and i tried adding the asset manually and it worked.
for example, I used the obj called andy_dance.fbx
so what I did was add this in the Gradle build
sceneform.asset('sampledata/models/andy_dance.fbx',
'default',
'sampledata/models/andy_dance.sfa',
'src/main/assets/andy_dance',
['sampledata/models/andy_dance.fbx'])
run or build your app and hopefully, it'll work
