編譯android系統apk
1、設置環境
|
1
2
3
|
export android_home=/home/administrator/soft/androidexport path=$path:$android_home/out/host/linux-x86/binexport android_product_out=$android_home/out/target/product/generic |
2、創建項目

android create project -t 1 -k com.lhw.led -a mainactivity -p ./ledavd id: 1，it's get by command "android list"project name: ledpackage: com.lhw.led main activity:mainactivityproject path: ./ |
接下來就是自己編寫android程序了。
3、編寫android.mk
android.mk需要放在項目根路徑下，即led下,內容：

|
local_path := $(call my-dir)include $(clear_vars)local_src_files := $(call all-subdir-java-files)local_package_name := led local_java_libraries := local_static_java_libraries :=include $(build_package) |
4、編譯
在android源碼目錄下執行：
|
1
2
|
./build/envsetup.shmmm /home/administrator/workspace/android_test/led/ |
執行結果：
|
1
|
install: out/target/product/generic/system/app/led.apk |
編譯android系統可執行命令
android系統允許開發者，自己編寫"ls"這樣的命令放到android系統中。
1、編寫c文件:mycmd.c

|
#include <stdio.h> int main(int argc, char **argv) { printf("this is my command!\n"); return 0; } |
2、編寫android.mk文件

|
local_path := $(call my-dir) local_src_files := mycmd.c local_module := mycmd local_module_tags := mycmd local_shared_libraries := libc local_static_libraries := include $(build_executable) |
3、編譯
|
1
|
mmm /home/administrator/workspace/android_test/mycmd/ |
編譯完成后信息：
|
1
|
install: out/target/product/generic/system/bin/mycmd |
