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
index 491cf8eada..a378ead82e 100755

+allow mtkbootanimation xunye_file:file { read write open ioctl map};
 allow mediaserver mtkbootanimation:dir search;
 
 allowxperm mtkbootanimation proc_ged:file ioctl { proc_ged_ioctls };

2.修改系统APP对新分区的权限

diff --git a/alps/device/mediatek/sepolicy/bsp/non_plat/system_app.te b/alps/device/mediatek/sepolicy/bsp/non_plat/system_app.te

这里包括了systemapp对logo.bin的修改权限

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

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);

            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";

        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) {

        }finally {

                if (os != null) {

            } 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/bash

if [ "$1" = "" ]; then
	echo "Please input BOOT_LOGO name,"
	echo "xunye"
	exit
fi

BASELOGO=$1
BOOT_LOGO_RESOURCE=boot_logo.raw

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；
