Abstract

La présente invention concerne un procédé et un appareil associé pour optimiser et exécuter une application Android. Dans la solution technique décrite dans la présente invention, un serveur optimise un fichier à optimiser dans un APK source de l'application Android, et envoie un APK cible à un dispositif terminal, l'APK cible comprenant un fichier d'optimisation cible obtenu par optimisation du fichier à optimiser ; après que le dispositif terminal a reçu l'APK cible, l'application Android est exécutée selon le fichier d'optimisation cible dans l'APK cible. Selon la solution technique de la présente invention, le serveur optimise l'APK, le dispositif terminal peut non seulement exécuter l'application Android optimisée de façon à améliorer l'efficacité d'exécution de l'application Android, mais peut également réduire une charge d'exécution du dispositif terminal, de façon à améliorer l'expérience de l'utilisateur.
