android - Viber 分享按钮在 Android 中抛出异常

Question

我正在开发 Android 应用程序。在我的应用程序中，我添加了 Viber 共享功能。所以我在网上搜索“How to share a content with viber in android”。然后我发现了 Viber 的业务。所以对于分享按钮，我点击了这个链接，https://www.viber.com/en/viber-share-button .如您所见，它非常简单。它只是要求使用 url 重定向到浏览器。所以我打开一个带有 url 的浏览器来在 viber 上分享，如下所示。

   private void shareOnViberClick()
        {
            Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("viber://forward?text=textIWantToShare"));
            startActivity(browserIntent);
        }

但是当我点击分享按钮并调用该方法时，它会抛出以下错误

为什么会抛出这个错误？我使用的 Viber 共享 API 是否正确？

Answer 1

不能保证 intent-filter 的 Activity 符合您的要求，因此 startActivity() 可能会失败，这应该在您的代码中处理。如果发生这种情况，它会抛出 ActivityNotFoundException，因此只需用 try/catch

包装您的 startActivity()
