android studio make build区别,Android studio--几个生成文件的区别：Make Project、Make Module、Build apk、Signed apk...

According to IntelliJ :

Project:

In the IntelliJ Platform, a project encapsulates all your source code, libraries, and build instructions into a single organizational unit. Everything you do using the IntelliJ Platform SDK is done within the context of a project. A project defines collections referred to as modules and libraries. Depending on the logical and functional requirements to the project, you can create a single-module or a multi-module project.

Module:

A module is a discrete unit of functionality that can be run, tested, and debugged independently. Modules includes such things as source code, build scripts, unit tests, deployment descriptors, etc. In the project, each module can use a specific SDK or inherit SDK defined on the project level (see the SDK section later in this document). A module can depend on other modules of the project.

signed APK:

signed packages to deploy and run your applications on physical devices. Based on this signature, the Android system identifies the author of every deployed application. You do not need to apply for a personal signature to any authority, a signature generated by IntelliJ IDEA is quite sufficient.

Build APK:

In debug mode, you sign your app with a debug certificate generated by the Android SDK tools. This certificate has a private key with a known password, so you can run and debug your app without typing the password every time you make a change to your project.

Android Studio signs your app in debug mode automatically when you run or debug your project from the IDE.
