Android意图过滤器在安装后不起作用

Question

我的应用程序注册了一个意图过滤器来打开一种用于在用户之间共享数据的文件，它工作正常，但有一个例外，如下所述。

安装应用程序后，在浏览器应用程序（例如 DropBox Android 应用程序）中单击导入文件后，该应用程序不会第一次出现在“完成操作使用”对话框中。但是，如果再次尝试导入，它会起作用 - 并且每次都如此。此外，如果应用程序在安装后且在尝试导入文件之前至少打开一次，它也可以工作。

值得注意的是，应用程序在运行时会立即打开，无需通过“使用完整操作”对话框，也无需将应用程序设置为默认值。

这确实经常出现在用户中，因为他们经常安装应用程序，然后立即尝试导入一些示例文件，因此应用程序以一些内容开始。

如何确保应用程序在安装后立即收到 Intent？

这是我的清单文件：

Answer 1

如果我没记错的话，android:mimeType 和 android:pathPattern 在同一个 <data> 标记中。一个<intent-filter> 中也应该只有一个<data>。我的建议：分成六个独立的<intent-filter>。

请注意，即使你做了也有我的问题How did intent-filter change from Android 2 to Android 4?
