Question

我想为我的应用程序创建一个反馈字段。我只想将用户重定向到这样的市场

String APP_MARKET_URL = "market://details?id=com.my.application"; 

Intent intent = new Intent( Intent.ACTION_VIEW, Uri.parse(APP_MARKET_URL)); 
this.startActivity(intent);

但是当我执行它时，我有这个错误：

我使用的是Android 1.5。我没有在清单中放入特定条目。有没有想法或其他方法来调用我的市场页面？

Answer 1

扩展上一条评论，您可以检查是否可以在设备上解析Intent，然后使用以下代码启动新的Activity：

    PackageManager pm = context.getPackageManager();
    ComponentName cn = intent.resolveActivity(pm);
    if (cn != null) {
        this.startActivity(intent);
    }

Answer 2

尝试在您的意图中添加以下单位。

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

Answer 3

如果您在模拟器上运行此代码，您应该知道模拟器上没有Android Market应用程序，因此它会抛出此异常。大多数真实设备应该没有问题。希望这会有所帮助。
