Hook函数之Runtime.getRuntime().exec

因为需要,需要隐藏包名,具体干嘛我就不说了.当然,这只是隐藏包名的一部分.还有其他方式能查看到包名.

 public static List<String> getAppList(Context context) {
        List<String> appList = new ArrayList<>();
        if (context == null) {
            return appList;
        }

        try {
            Process process = Runtime.getRuntime().exec("pm list package -3");
            BufferedReader bis = new BufferedReader(new InputStreamReader(process.getInputStream()));
            String line = null;
            while ((line = bis.readLine()) != null) {
                System.out.println("MainActivity.runCommand, line=" + line);
                appList.add(line.replace("package:", ""));
            }
        } catch (IOException e) {
            System.out.println("MainActivity.runCommand,e=" + e);
        }
        return appList;
    }

hook前
I/System.out( 2657): =========>>>com.alibaba.android.rimet
I/System.out( 2657): =========>>>com.oneweone.kangaroo
I/System.out( 2657): =========>>>de.robv.android.xposed.installer
I/System.out( 2657): =========>>>kaiqi.cn.xposed002
I/System.out( 2657): =========>>>com.qxq.shenqi

I/System.out( 2657): =========>>>com.netease.faket_android_launcher.faket

hook后
I/System.out( 3702): 当前包名是-------->com.oneweone.kangaroo
I/System.out( 3702): 当前包名是-------->kaiqi.cn.xposed002
I/System.out( 3702): 当前包名是-------->com.qxq.shenqi
I/System.out( 3702): 当前包名是-------->ksh.skk
I/System.out( 3702): 当前包名是-------->com.netease.faket_android_launcher.faket
I/System.out( 3702): 当前包名是-------->kaiqi.cn.tst

hook核心代码
