11这篇文章介绍了一种在FPC中编译一个工程并将其下载到Android设备的方法. 它认为该工程是一个加载在Java代码中的NDK库。当然，这个方法并没有绑定到任何的IDE扩展部分中(例如:Android4Laz),可单独地应用于任何工程.
22
33## 必备条件
44
55- FPC (附带有预制好的Android的rtl库).
66- JRE (Java运行时) - 需要JDK,以及来运行"java"的机器(用于执行包含在Android SDK中的实用程序)
77- JDK (需要安装javac ),JDK需要安装JRE.
88- Android NDK
99- Android SDK
1010
1111不需要附加的构建工具(例如，ant)
1212
1313### JRE / JDK 版本
1414
1515目前(2017年冬季),可下载仅受官方支持版本8(1.8).以前,你可以下载版本7.Android SDK的很多组件都绑定到JDK的具体版本.
1616
1717## 编译
1818
19190\. 它假设整个工程都在一个文件夹中,例如"mydemo".并且在android下用于构建的所有的脚本和实用程序都位于"mydemo \\ android".这只在接下来的具体指定-FE开关的步骤中起作用.
2020
21211\. 你需要编译工程(库).命令行(windows)可能看起来像这样.

3941- -FD - specifies the path where build utilities are stored
4042- -XParm-linux-androideabi- - specifies the prefix for the build utilities
4143- -Fu - pointing to NDK libraries - required for linking
4244- -FE - specifies the path where the created library should be written. The destination directory in this case is listed as "lib \\ armeabi". This path will be saved in the apk itself. It should be just that, because it is tied to the target architecture (arm). For arm64 or arm7, the path must be different. All third-party dynamic link libraries for ARM architecture should also be located in the lib \\ armeabi folder.

6066该实用程序创建一个 initial .apk file (-F bin\\%APP_NAME% .ap_ - the extension is specified as "ap_" intentionally, since this is not a final file), as well as a R.java file in the "gen" folder (-J gen). When creating an apk (essentially a .zip) file, the "files" folder will be included. (at step \# 1, the library "-FE.\android\files\lib\armeabi\\" was copied into it, so "lib\armeabi\mydemo.so" will get into the apk file) "-S" indicates the folder with standard android resources (icons and layout xml-s), the folder will be copied to .apk The structure of the generated .apk file will look like this:

8599It is important to specify "-cp" (class-path) for the used Android-SDK. The java compiler, like jdk itself, does not know anything about the android system. And the compiled program will use the SDK classes. Therefore, if the class-path is not specified, then errors will appear that the class is not declared, etc. -d - specifies the path where to put the compiled .class files, they are needed in the next step.

119143At the time of writing the script, there was no separate utility for adding classes.dex to the .apk file ... But here ApkBuilderMain is called (via a call to the java machine). The only thing it does is add classes.dex (created in step \# 5) to the root folder of the existing .apk file (created in step \# 3 .ap_) and write it to the -unsigned.apk file. A regular zip utility (like 7z) would probably do just as well.
