判断某个应用是否安装，可以通过PM查询应用中AndroidManifest.xml中配置的broadcast receiver是否存在，比如判断stk应用是否已安装：

    private boolean isStkAppInstalled() {
        Intent intent = new Intent(AppInterface.CAT_CMD_ACTION);
        PackageManager pm = mContext.getPackageManager();
        List<ResolveInfo> broadcastReceivers =
                            pm.queryBroadcastReceivers(intent, PackageManager.GET_META_DATA);
        int numReceiver = broadcastReceivers == null ? 0 : broadcastReceivers.size();

        return (numReceiver > 0);
    }
