Compiling method of Android system application program

Abstract

The invention discloses a compiling method of an Android system application program. The method comprises the following steps: aiming at each module for interaction between an application layer to berealized by the APP and a system operation layer, selecting a base class and / or method, which needs to be inherited when the module is compiled and is not disclosed in the Android SDK, from the Android system; compiling and packaging into a jar package, and providing the jar package for an installation program APK of the APP to be compiled; packaging a hidden interface between an HIDL interface ofthe module and a system operation layer into another jar package, and providing the jar package as an interface dependence library for the APK for compiling; and compiling the APK by using the one jar package and the other jar package for each module. By applying the method, single-bin compiling of the application program can be realized.

Description

technical field [0001] The present application relates to Android system technology, in particular to a compiling method of an Android system application program (APP). Background technique [0002] Android 8.0 google introduced a very important feature called Project treble, which provides a stable new supplier interface, so that device manufacturers only need to update the Android operating system framework, skipping chip manufacturers to directly provide new Android version, its purpose is to solve the problem of Android version fragmentation. [0003] Hardware Abstraction Layer (HAL) Interface Definition Language (HIDL) is an Interface Description Language (IDL) for specifying the interface between a HAL and its users. HIDL allows the specification of type and method calls, where the specified types and methods are assembled into interfaces and packages. In a broader sense, HIDL is a system for communicating between codebases that can be compiled independently. [000...

AI Technical Summary

Problems solved by technology

However, after the introduction of the HIDL framework, many dependent classes that need to be inherited are not exposed in the Android SDK. For apps that need to realize the interaction between the application layer and the system running layer and thus rely on the HIDL interface (such as apps that need to implement RIL), use the HIDL interface It is impossible to directly inherit and reference these hidden dependent classes. Therefore, single warehouse compilation cannot be realized, resulting in APP only being developed and compiled in the source code, losing flexibility
