Qualcuno può indicarmi il modo giusto per risolvere questo problema? Per favore aiutatemi!

Grazie,

Answer 1

Unsupported major.minor version 52.0 significa che si sta utilizzando la versione sbagliata di JDK. Dovrai aggiornare il tuo JDK alla versione 8, poiché stai impostando la tua versione della lingua JAVA su 1.8.

Scarica JDK 8 da Oracle:

Answer 2

Ho anche affrontato lo stesso problema, può essere risolto seguendo due fasi:

Passo 1: Scaricare Java 8. Fase 2: Aggiornamento Android Studio alla versione più recente 2.2.
