如何以编程方式检测应用是否支持Android Wear？

Question

我试图检测一个应用程序是否支持Android Wear或是一个表盘。

PackageManager pm = getActivity().getPackageManager(); 

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

是我使用的代码。任何反馈或建议都会很糟糕！

要检查系统中已存在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; 
    } 
}
