Problems solved by technology

[0011] It can be seen that the implementation of calling JNI is more complicated, and a large amount of intermediate code will be generated, which will not only affect the operating efficiency of the machine, but also increase the probability of compilation failure or operation failure.

Abstract

The invention relates to an embodiment comprising an order processing method, device and terminal, and refers to the computer field; the method and device can realize interaction communication between upper layer applications and hardware bottom layer without invoking JNI; the method comprises the following steps: intercepting an order and a secret order sent by an application of the terminal and used for starting a bottom layer drive program execution, wherein the secret order is formed by pre-using a preset public key to encrypt the order; using a preset private key to decrypt the intercept secret order according to a preset decryption algorithm, comparing the intercepted order with the decrypted order, and carrying out ID validity authentication for the application according to the comparison result; converting the order into a format recognizable by the bottom layer drive program when the application passes the ID validity authentication, and transferring the converted order to the corresponding bottom layer drive program for execution, thus realizing said functions.

Description

technical field [0001] The present invention relates to the field of computers, in particular to an instruction processing method, device and terminal. Background technique [0002] The Java language is popular for its cross-platform characteristics. Android is a system developed based on the Java language. On the Android platform, the execution files are packaged in APK (Android Package, ie Android installation package) format. However, due to the cross-platform characteristics of the Java language, the Java language is separated from the connection with the bottom layer of the hardware, which restricts its application. In order to solve the above-mentioned defects, the prior art can be realized by JNI (Java Native Interface, Java local interface) and the bottom layer of the hardware (using machine language or other languages, such as writing in C / C ++) or other application programs (using other languages, such as C / C++, etc.) interaction. In practice, APK calls local me...
