make Project、clean Project、Rebuild Project的区别

我去网上搬运几个关于它们的区别，先上stackOverFlow的：

Most of the time you should use Make Project. Sometimes, after adding libraries and making big changes to the project you should use Rebuild Project.

If you look at the menu, you’ll see that Make Project and Compile have keyboard shortcuts, that suggests that they are often used. Others are seldom used.

It is the same as IntelliJ Idea.

Compile All the source files in the specified scope are compiled. The scope in this case may be a file, a package, etc.

Make Project All the source files in the entire project that have been modified since the last compilation are compiled. Dependent source files, if appropriate, are also compiled. Additionally, the tasks tied to the compilation or make process on modified sources are performed. For example, EJB validation is performed if the corresponding option is enabled on the Validation page.

Make Module Compiled are all the source files that have been modified since the last compilation in the selected module as well as in all the modules it depends on recursively.

Rebuild Project All the source files in the project are recompiled. This may be necessary when the classpath entries have changed, for example, SDKs or libraries being used added, removed or altered

前面三段我还勉强能看懂，后边就看不下去了，接下来，我去搬运一点中文版的区别。

1. Make Project：编译整个Project中在上次编译之后有改动的所有文件。依赖资源文件，如果合适，也会被编译。此外，不生成apk。
2. Make Selected Modules：编译指定的Module，一般是自上次编译后Module下有更新的文件，不生成apk。
3. Clean Project：删除之前编译后的编译文件，并重新编译整个Project，比较花费时间，不生成apk。
4. Rebuild Project：先执行Clean操作，删除之前编译的编译文件和可执行文件，然后重新编译新的编译文件，不生成apk，这里效果其实跟Clean Project是一致的，这个不知道Google搞什么鬼～～
5. Build APK：前面4个选项都是编译，没有生成apk文件，如果想生成apk，需要点击Build APK。
6. Generate Signed APK：生成有签名的apk。
