android - 如何在Android设备上获取已安装apk的子进程信息

Question

我们可以在AndroidManifest.xml 中为 Activity 或服务定义android:process，命名为子进程。例如，我的包名称是 'com.test.main' 并且我定义了两个子流程:

android:process=":tool"
android:process=":bar"

我的问题是:

将apk文件安装到android设备后，我们如何获取所有这些子进程列表信息，例如com.test.main:tool，com.test.main:bar，通过 adb 或其他已安装的应用程序？

    String pkg = "com.google.android.gms";
    try {

        // Ref: https://developer.android.com/guide/components/processes-and-threads

        PackageInfo packageInfo = getPackageManager().getPackageInfo(pkg, PackageManager.GET_ACTIVITIES | PackageManager.GET_SERVICES | PackageManager.GET_RECEIVERS | PackageManager.GET_PROVIDERS);


        List<ComponentInfo> list = new ArrayList<>();

        if (packageInfo.activities != null) Collections.addAll(list, packageInfo.activities);
        if (packageInfo.services != null) Collections.addAll(list, packageInfo.services);
        if (packageInfo.receivers != null) Collections.addAll(list, packageInfo.receivers);
        if (packageInfo.providers != null) Collections.addAll(list, packageInfo.providers);

        for (ComponentInfo componentInfo : list) {

            Utils.log("componentInfo: " + componentInfo.processName);
        }

    } catch (PackageManager.NameNotFoundException e) {
        e.printStackTrace();
    }
