去掉XOSLauncher自带的widget组件图标

FrameNotWork2025-12-03 13:20

背景：系统集成了XOSLauncher，无源码。要求去掉其自带的一键清理、一键壁纸图标。通过系统源码尝试无果，发现这是launcher通过hard-coding写入的。

1.发现

在采用多种办法尝试无果之后，无意间操作图标进行移除时获取到以下日志。

复制代码 
LauncherPreAnalytics: postAthenaEvent tid = 9461 eventName = launcher_widget_show_list bundle = Bundle[{widget_list=["{\"widget_name\":\"com.android.launcher3.widget.VerticalClockWidget\"}"], widget_name=com.transsion.xlauncher.switchwallpaper.SwitchWidget, status=0}]

此为线索一。

2.反编译

通过一系列排查可以确认这些是内部组件，需要：

复制代码 
# 1. 导出 APK
adb pull /system/priv-app/XOSLauncher/XOSLauncher.apk

# 2. 反编译
apktool d XOSLauncher.apk -o XOSLauncher_src

# 3. 查找"一键清理"、"一键壁纸"相关的代码和资源
cd XOSLauncher_src
grep -r "一键清理\|一键壁纸" res/values*/strings.xml
grep -r "SwitchWidget\|CleanWidget" smali/

# 4. 找到对应的布局文件
find res/layout -name "*.xml" | xargs grep -l "清除\|壁纸\|switch\|clean"

# 5. 找到添加这些组件的代码（通常在 Workspace 或 Launcher 类中）
find smali -name "*Workspace*.smali" -o -name "*Launcher*.smali" | xargs grep -l "addWidget\|addShortcut"

# 6. 修改代码跳过添加这些组件，或直接删除相关资源文件

# 7. 重新打包
apktool b XOSLauncher_src -o XOSLauncher_mod.apk

# 8. 签名并安装

通过反编译确实查找了到了相关的源码信息，结果如下：

复制代码 
guan@DESKTOP-EA83T13:~/XOSLauncher_src$ grep -r "一键清理\|一键壁纸" res/values*/strings.xml
res/values-zh-rCN/strings.xml:    <string name="clean_widget_title">一键清理</string>
res/values-zh-rCN/strings.xml:    <string name="switch_wallpaper_title">一键壁纸</string>
guan@DESKTOP-EA83T13:~/XOSLauncher_src$ grep -r "SwitchWidget\|CleanWidget" smali/
smali/com/android/launcher3/LauncherModel.smali:    const-string v1, "com.android.systemui/com.android.systemui.widget.clean.CleanWidgetProvider"

smali/com/android/launcher3/model/w1.smali:    const-string v7, "com.android.systemui/com.android.systemui.widget.clean.CleanWidgetProvider"
smali/com/android/launcher3/model/w1.smali:    const-class v7, Lcom/transsion/xlauncher/clean/CleanWidget;
smali/com/android/launcher3/model/w1.smali:    const-class v7, Lcom/transsion/xlauncher/switchwallpaper/SwitchWidget;
smali/com/android/launcher3/model/WidgetsModel.smali:    const-class v3, Lcom/transsion/xlauncher/switchwallpaper/SwitchWidget;
smali/com/android/launcher3/widget/c.smali:    const-class v1, Lcom/transsion/xlauncher/clean/CleanWidget;
smali/com/android/launcher3/widget/c.smali:    const-class v1, Lcom/transsion/xlauncher/switchwallpaper/SwitchWidget;

这些 Widget 是在代码中硬编码添加的。现在我们需要修改这些 smali 文件，阻止这些 Widget 被创建和显示。

关键文件分析

从结果看，主要涉及：

  1. Launcher.smali - 主 Launcher 类
  2. s1.smali - 负责创建 Widget 实例
  3. w1.smali 和 WidgetsModel.smali - Widget 模型管理
  4. widget/c.smali - Widget 相关逻辑

先执行以下命令：

复制代码 
# 1. 查看 s1.smali 中创建 Widget 的完整代码
cat ~/XOSLauncher_src/smali/com/android/launcher3/model/s1.smali | grep -B 15 -A 15 "new-instance.*CleanWidget"

# 2. 查看 SwitchWidget 的创建代码
cat ~/XOSLauncher_src/smali/com/android/launcher3/model/s1.smali | grep -B 15 -A 15 "new-instance.*SwitchWidget"

# 3. 查看 WidgetsModel.smali 中如何添加 Widget 到列表
cat ~/XOSLauncher_src/smali/com/android/launcher3/model/WidgetsModel.smali | grep -B 20 -A 20 "SwitchWidget"

执行结果：

复制代码 
guan@DESKTOP-EA83T13:~/XOSLauncher_src$ cat ~/XOSLauncher_src/smali/com/android/launcher3/model/s1.smali | grep -B 15 -A 15 "new-instance.*CleanWidget"

3.修改方案

修改 s1.smali（最简单有效）
复制代码 
cd ~/XOSLauncher_src
vim smali/com/android/launcher3/model/s1.smali

找到这段代码（大约在 line 2-3）：

复制代码 
	.line 2
    new-instance v0, Lcom/transsion/xlauncher/clean/CleanWidget;
    invoke-direct {v0}, Lcom/transsion/xlauncher/clean/CleanWidget;-><init>()V
    const v1, 0x6e55c594
    invoke-virtual {p0, p1, v1, v0}, Lcom/android/launcher3/model/s1;->a(Landroid/content/Context;ILcom/android/launcher3/o5;)V
    .line 3
    new-instance v0, Lcom/transsion/xlauncher/switchwallpaper/SwitchWidget;
    invoke-direct {v0}, Lcom/transsion/xlauncher/switchwallpaper/SwitchWidget;-><init>()V
    const v1, -0x4be2bc14
    invoke-virtual {p0, p1, v1, v0}, Lcom/android/launcher3/model/s1;->a(Landroid/content/Context;ILcom/android/launcher3/o5;)V

完全删除或注释掉这两段（推荐注释，方便恢复）：

复制代码 
	.line 2
    # new-instance v0, Lcom/transsion/xlauncher/clean/CleanWidget;
    # invoke-direct {v0}, Lcom/transsion/xlauncher/clean/CleanWidget;-><init>()V
    # const v1, 0x6e55c594
    # invoke-virtual {p0, p1, v1, v0}, Lcom/android/launcher3/model/s1;->a(Landroid/content/Context;ILcom/android/launcher3/o5;)V
    .line 3
    # new-instance v0, Lcom/transsion/xlauncher/switchwallpaper/SwitchWidget;
    # invoke-direct {v0}, Lcom/transsion/xlauncher/switchwallpaper/SwitchWidget;-><init>()V
    # const v1, -0x4be2bc14
    # invoke-virtual {p0, p1, v1, v0}, Lcom/android/launcher3/model/s1;->a(Landroid/content/Context;ILcom/android/launcher3/o5;)V

保存并退出后，重新打包

复制代码 
cd ~
apktool b XOSLauncher_src -o XOSLauncher_nowidgets.apk

# 检查是否编译成功
ls -lh XOSLauncher_nowidgets.apk

如果编译成功，你会看到生成的 APK 文件。

签名 APK
复制代码 
# 1. 先对齐
zipalign -p -f 4 XOSLauncher_nowidgets.apk XOSLauncher_aligned.apk

# 2. 使用 apksigner 签名（会自动处理对齐）
apksigner sign --key platform.pk8 --cert platform.x509.pem XOSLauncher_aligned.apk

# 3. 验证
apksigner verify -v XOSLauncher_aligned.apk

# 4.检查对齐
zipalign -c -v 4 XOSLauncher_signed.apk
安装APK
复制代码 
# 1. 获取 root 权限
adb root

# 2. 重新挂载系统分区为可写
adb remount

# 3. 备份原 APK（如果还没备份）
adb shell cp /system/priv-app/XOSLauncher/XOSLauncher.apk /system/priv-app/XOSLauncher/XOSLauncher.apk.bak

# 4. 推送新 APK
adb push XOSLauncher_aligned.apk /system/priv-app/XOSLauncher/XOSLauncher.apk

# 5. 设置正确的权限和 SELinux 上下文
adb shell chmod 644 /system/priv-app/XOSLauncher/XOSLauncher.apk
adb shell chown root:root /system/priv-app/XOSLauncher/XOSLauncher.apk
adb shell chcon u:object_r:system_file:s0 /system/priv-app/XOSLauncher/XOSLauncher.apk

# 6. 清除应用数据并重启
adb shell pm clear com.transsion.XOSLauncher
adb reboot

查看是否生效。
