Source scheint fehlerfrei zu sein -> Gradle kann ihn trotzdem nicht bauen. Eventuell hat eine eingebundene *.jar Schuld.

UPDATE

Lösung: Man sollte die jar natürlich in das passende - zum gradl Konfigurationfile passenden ordner schieben. also z.B. nicht im Projekt-Root sondern wenn es die gradle für /app ist dann natürlich in app/libs.

Hi ihr,
ich erstelle gerade mein erste Android App. Diese ist eigentlich nur ein "Playground" um mir bissl die Entwicklung von Apps anzusehen.

Ich habe eine fremde jar im Einsatz, aber auch diese wird von der IDE her gut erkannt. Auch sonst zeigt die Entwicklungsumgebung das Projekt als baubar an.

Könnt ihr mir helfen? Wäre supi!

LG, Tobi
