android - 如何以编程方式检测应用程序是否支持 Android Wear？

Question

我正在尝试检测应用程序是否支持 Android Wear 或是否是表盘。

PackageManager pm = getActivity().getPackageManager();

        List<PackageInfo> packs = pm.getInstalledPackages(0);
        for (int i = 0; i < packs.size(); i++)
        {}

我正在使用的代码。任何反馈或建议都会很棒!

检查系统中是否存在 Android Wear 包:

public void foobar() {
    boolean doesExist = isPackageInstalled("com.google.android.wearable.app");
}

private boolean isPackageInstalled(String packagename) {
    PackageManager pm = getApplicationContext().getPackageManager();
    try {
        pm.getPackageInfo(packagename, PackageManager.GET_ACTIVITIES);
        return true;
    } catch (NameNotFoundException e) {
        //swallow exception
        return false;
    }
}
