一、Android蒙版
Android启动画面：./framework/base/core/res/assets/images/，其中一个是mask，另一个是shine，需要设置相同分辨率。
二、Bootanimation
2.1 bootanimation.zip
part0
part1
# part* ...
desc.txt part*中存放连续命名，例如*000.png、*001.png的图片。desc.txt的基本语法如下，详细语法参考此处：
720 1280 30
p 0 0 part0
注意：
- 此处的回车换行，应该采用
LF而不是CRLF。 - 在编写的最后一行，应该留空。例如上面在
p 0 0 part0这行完成之后按下回车，整个文件共有3行。
bootanimation.zip压缩采用“仅储存”的方式，Linux命令如下：
zip -r -0 bootanimation.zip part0 desc.txt注意，这里直接打包part*和desc.txt，不需要将其作为一个文件夹打包。
2.2 存放位置
bootanimation.zip的存放位置可以在./framework/base/cmds/bootanimation/BootAnimation.cpp中查看其存放位置。本平台的存放位置如下：
static const char OEM_BOOTANIMATION_FILE[] = "/oem/media/bootanimation.zip";
static const char PRODUCT_BOOTANIMATION_DARK_FILE[] = "/product/media/bootanimation-dark.zip";
static const char PRODUCT_BOOTANIMATION_FILE[] = "/product/media/bootanimation.zip";
static const char SYSTEM_BOOTANIMATION_FILE[] = "/system/media/bootanimation.zip";
static const char APEX_BOOTANIMATION_FILE[] = "/apex/com.android.bootanimation/etc/bootanimation.zip";
static const char PRODUCT_ENCRYPTED_BOOTANIMATION_FILE[] = "/product/media/bootanimation-encrypted.zip";
static const char SYSTEM_ENCRYPTED_BOOTANIMATION_FILE[] = "/system/media/bootanimation-encrypted.zip";
static const char OEM_SHUTDOWNANIMATION_FILE[] = "/oem/media/shutdownanimation.zip";
static const char PRODUCT_SHUTDOWNANIMATION_FILE[] = "/product/media/shutdownanimation.zip";
static const char SYSTEM_SHUTDOWNANIMATION_FILE[] = "/system/media/shutdownanimation.zip";我们将制作好的bootanimation.zip存放到上述的位置。如果想在编译时自动添加，则按照如下操作：
- 找到
var.mk，本项目是./device/sprd/mpool/product/var.mk，在其中添加：
PRODUCT_COPY_FILES += bootanimation/bootanimation.zip:system/media/bootanimation.zip
# PRODUCT_COPY_FILES+= source_path/source_file:target_path/target_file- 设置权限（不一定需要），在
./system/core/libcutils/fs_config.cpp中依葫芦画瓢添加你需要的文件的路径即可。路径权限在android_dirs中添加。
static const struct fs_path_config android_files[] = {
