Answer 1

Ihre IBM Mobile First Plattformabhängigkeit in der build.gradle ändern zu

compile(name: 'ibmmobilefirstplatformfoundation:8.0.2017040512', ext: 'aar') 

Gemäß der Dokumentation here dies die neueste zertifizierte Version für 8.0 ist. Dies sollte dein Problem lösen.

Als Best Practice empfiehlt es sich, bestimmte Versionsnummern anzugeben, um sicherzustellen, dass keine Überraschungen auftreten. Die Verwendung der dynamischen Version kann immer ein Problem sein. Mehr dazu hier http://blog.danlew.net/2015/09/09/dont-use-dynamic-versions-for-your-dependencies/.
