T820 Dev 04 Boot Animation

发布于 2024-03-28  51 次阅读


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

  1. 此处的回车换行,应该采用LF而不是CRLF
  2. 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:

  1. 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
  1. 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[] = {
