MTK APP实现动态修改logo和开机动画

---

前言

之前写过如何动态替换开机logo的MTK修改动态切换开机logo，恢复出厂设置不还原
以及OTA升级开机logo的MTK android10修改Logo OTA AB分区
但是又有需求，动态替换开机动画，开机logo，不随OTA升级变化，但是开机动画实际上是在system分区中的，OTA升级如果有修改，就会替换，而且，开机动画文件是只读文件，就相出了一个方法， 新建一个分区，把开机动画放入新分区中，这个分区不加入OTA升级，
先看新加分区的修改MTK Android10添加分区
不同平台或者android版本的话，大部分是一样的，修改思路相同

---

一、修改对新分区的权限

1.修改开机动画对新分区的权限

diff --git a/alps/device/mediatek/sepolicy/basic/non_plat/mtkbootanimation.te b/alps/device/mediatek/sepolicy/basic/non_plat/mtkbootanimation.te

2.修改系统APP对新分区的权限

3.修改SE权限,不然编译会报错

4.修改开机动画文件，让其加载新分区中的文件

复制文件到新分区中

index 22e9bdc759..8fd857fd9c 100755

修改bootanimation.cpp ，这个其实比较简单， 把默认加载system/media的目录改成xunye/media即可；

二、系统APP代码使用

1.系统app修改开机logo

public static void copyLogoBin() {File srcFile = new File("/sdcard/logo.bin");if(!srcFile.exists())return;String logoPath = "dev/block/platform/bootdevice/by-name/logo";
//        String logoPath = "/dev/block/mmcblk0p19";Log.e("logo","logoPath="+logoPath);File dstFile =  new File(logoPath);OutputStream os = null;try {FileInputStream is = new FileInputStream(srcFile);os = new BufferedOutputStream(new FileOutputStream(dstFile, false));int curSize = 0;byte[] data = new byte[1024];for (int len; (len = is.read(data)) != -1; ) {os.write(data, 0, len);curSize += len;}} catch (Exception e) {e.printStackTrace();}finally {try {if (os != null) {os.close();}} catch (IOException e) {e.printStackTrace();}
//            srcFile.delete();}}

2.系统app修改开机动画

public static void copyLogoBootanimation() {File srcFile = new File("/sdcard/bootanimation.zip");if(!srcFile.exists())return;String logoPath = "/xunye/media/bootanimation.zip";
//        String logoPath = "/dev/block/mmcblk0p19";Log.e("logo","BootanimationPath="+logoPath);File dstFile =  new File(logoPath);if(dstFile.exists())dstFile.delete();try {dstFile.createNewFile();} catch (IOException e) {throw new RuntimeException(e);}try {Os.chmod(dstFile.getAbsolutePath(), 0777);} catch (ErrnoException e) {e.printStackTrace();}OutputStream os = null;try {FileInputStream is = new FileInputStream(srcFile);os = new BufferedOutputStream(new FileOutputStream(dstFile, false));int curSize = 0;byte[] data = new byte[1024];for (int len; (len = is.read(data)) != -1; ) {os.write(data, 0, len);curSize += len;}} catch (Exception e) {e.printStackTrace();}finally {try {if (os != null) {os.close();}} catch (IOException e) {e.printStackTrace();}
//            srcFile.delete();}}

3.系统app修改开机音乐

public static void copyBootAudio() {File srcFile = new File("/sdcard/bootaudio.mp3");if(!srcFile.exists())return;String logoPath = "/xunye/media/bootaudio.mp3";
//        String logoPath = "/dev/block/mmcblk0p19";Log.e("logo","bootaudio.mp3 Path="+logoPath);File dstFile =  new File(logoPath);if(dstFile.exists())dstFile.delete();try {dstFile.createNewFile();} catch (IOException e) {throw new RuntimeException(e);}try {Os.chmod(dstFile.getAbsolutePath(), 0777);} catch (ErrnoException e) {e.printStackTrace();}OutputStream os = null;try {FileInputStream is = new FileInputStream(srcFile);os = new BufferedOutputStream(new FileOutputStream(dstFile, false));int curSize = 0;byte[] data = new byte[1024];for (int len; (len = is.read(data)) != -1; ) {os.write(data, 0, len);curSize += len;}} catch (Exception e) {e.printStackTrace();}finally {try {if (os != null) {os.close();}} catch (IOException e) {e.printStackTrace();}
//            srcFile.delete();}}

三、如何定制开机logo

需要几个文件，在linux下编译
vendor/mediatek/proprietary/bootable/bootloader/lk/dev/logo/tool/bmp_to_raw
vendor/mediatek/proprietary/bootable/bootloader/lk/dev/logo/tool/zpipe
vendor/mediatek/proprietary/bootable/bootloader/lk/dev/logo/img_hdr_logo.cfg
vendor/mediatek/proprietary/bootable/bootloader/lk/scripts/mkimage
然后复制一下logo.bin编译的脚本，修改成make_logo.sh文件
如下

#!/bin/bashif [ "$1" = "" ]; thenecho "Please input BOOT_LOGO name,"echo "xunye"exit
fiBASELOGO=$1
BOOT_LOGO_RESOURCE=boot_logo.raw

./mkimage ${BOOT_LOGO_RESOURCE} img_hdr_logo.cfg  > logo.bin

编译的时候，替换xunye文件夹中的xxxxxx_uboot.bmp，xxxxxx_kernel.bmp两个文件，即logo图片
./make_logo.sh xunye就行，生成的logo.bin放入sd卡中替换

总结

logo.bin没有修改，动态修改logo.bin，只是修改了系统app对logo分区的修改权限；
开机动画与开机音乐是加入到新分区中的，然后对新分区修改SE权限，和读写权限，让系统APP能够修改，同时该分区不随OTA升级，所以用户即使替换了，升级之后也没有变化；
