The method comprises steps as follows: APKs containing credit-granted application list files are signed, the signed APKs are obtained, and each credit-granted application list file comprises package names of each credit-granted APK and a corresponding public key certificate; a terminal acquires the signed APKs; the legality of the signed APKs is verified, and the credit-granted application list files are stored after verification is passed; one APK is acquired, and the legality of the APK is verified; if the verification isn't passed, whether a package head of the APK and the corresponding public key certificate are stored in the credit-granted application list files is judged; if yes, the legality of the APK is verified by continuously using an Android signature mechanism. The credit-granted application list files are added, the credit-granted APK downloading and installing process is simplified, and the updating and upgrading process of the credit-granted APKs is further simplified; influence of application update and upgrade to normal work of the terminal is reduced.
