如何使用软件包管理器获得Android设备特点 [英] how to get Android device Features using package manager

问题描述

我正在开发相关的获得Android设备的功能的应用程序。我是新来的机器人。我知道，通过包管理器，getSystemAvailableFeatures方法，我们可以做到这一点。还是我不能抽到的功能。任何一个可以帮我邮寄一些示例源代码或code相关的。

推荐答案

我用下面的函数来确定一个功能是否可用：

I use the following function to determine if a feature is available:

    public final static boolean isFeatureAvailable(Context context, String feature) {
        final PackageManager packageManager = context.getPackageManager();
        final FeatureInfo[] featuresList = packageManager.getSystemAvailableFeatures();
        for (FeatureInfo f : featuresList) {
            if (f.name != null && f.name.equals(feature)) {
                 return true;
            }
        }

       return false;
    }

的使用（即自Activity类）：

The usage (i.e from Activity class):

    if (isFeatureAvailable(this, PackageManager.FEATURE_CAMERA)) {
        ...
    }
