miui_patch 简易教程

准备工作

访问 MIUI官网 下载你使用机型的卡刷包

使用 SuperR's Kitchen 解包以及全局 deodex 处理

deodex后将以下目录拷贝出来（后面用到）

.
└── system
    ├── app
    ├── framework
    ├── priv-app
    └── vendor
        ├── app
        └── framework

应用 miui_patch

使用 apktool 反编译需要修改的 APK，执行相应方案的修改并回编（注意保留源签名），然后替换到原来的APK。

miui_patch 修改策略中的 return false、return true 针对布尔方法（函数名以字母 Z 结尾），return null 针对无返回值的方法（函数名以字母 V 结尾）。

return true 指将方法的函数体修改为以下代码：

.locals 1

const/4 v0, 0x1

return v0

return false 指将方法的函数体修改为以下代码：

.locals 1

const/4 v0, 0x0

return v0

return null 指将方法的函数体修改为以下代码：

.locals 0

return-void

注意：如果你在代码中若使用了 Lcom/winter/mysu;->TRUE:Z，必须将 patch 目录下的 smali 文件夹拷贝到相应位置（这很重要！！！）。

删除 MIUI 冗余的 APP

请参考每个分支下 patch/remove_list.md 文件的说明删除你不需要的MIUI组件。

制作miui_patch卡刷包

下载模板文件 sample.zip 解压，目录结构如下：

.
├── META-INF
│   └── com
│       └── google
│           └── android
│               ├── update-binary
│               └── updater-script  # 刷机脚本
└── system
    ├── app
    ├── framework
    ├── priv-app
    └── vendor
        ├── app
        └── framework

miui_patch 通过全局替换 deodex 后的 APK/JAR 到系统达到修改的目的。

将你修改好的 system 目录下的相应内容覆盖到 smaple/system 目录下。

生成刷机脚本 updater-script，参考示例：

ifelse(is_mounted("/cust"), unmount("/cust"));
ifelse(is_mounted("/system"), unmount("/system"));

mount("ext4", "EMMC", "/dev/block/bootdevice/by-name/cust", "/cust", "max_batch_time=0,commit=1,data=ordered,barrier=1,errors=panic,nodelalloc");
delete_recursive("/cust/app");
delete_recursive("/cust/cust");
unmount("/cust");

ui_print("Extracting system...");
mount("ext4", "EMMC", "/dev/block/bootdevice/by-name/system", "/system", "max_batch_time=0,commit=1,data=ordered,barrier=1,errors=panic,nodelalloc");

# 清理旧内容
delete_recursive("/system/app");
delete_recursive("/system/data-app");
delete_recursive("/system/framework");
delete_recursive("/system/priv-app");
delete_recursive("/system/vendor/app");
delete_recursive("/system/vendor/framework");

# 如果你精简的APP包含动态链接库，一并删除
# 可选，你不删也没事
delete("/system/lib64/libmtk_serialnum.so");
delete("/system/lib64/libxmpass_sdk_patcher.so");
delete("/system/lib64/xmpass_libweibosdkcore.so");

# 这是为了防止恢复官方recovery
delete("/system/bin/install-recovery.sh");
delete("/system/etc/recovery-resource.dat");
delete("/system/recovery-from-boot.p");

package_extract_dir("system", "/system");

# 链接动态链接库，很重要
# 如果你替换的组件使用了动态链接库，必须重新链接
# 可以参考 SuperR's Kitchen 生成的 symlinks

大功告成！现在你可以打包成 zip 卡刷包，并通过TWRP刷进你的手机~
