我一直对被设置为打开一个文件具有特定扩展名的应用程序。它的工作原理与Gmail一些时间(有些文件打开,而有些则没有),我可以打开文件浏览器中的文件。
I've been working on an application which is set to open a file with a specific extension. It works some times with Gmail (some files open, while some don't), and I can open a file from the file explorer.
我无法打开来自电子邮件应用程序的文件在手机上却和我说,一些文件没有从我的应用程序和一些呢!
I can't open the files from the Email application on the phone however and as I say, some files do not open from the Gmail application with my application and some do!
下面是我的code。
<intent-filter > <!-- Solution from @richardlegget on this question http://stackoverflow.com/questions/8148629/intent-filter-to-download-attachment-from-gmail-apps-on-android -->
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="application/octet-stream" android:pathPattern=".*\\.myextension" />
</intent-filter>
<intent-filter >
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="*/*" android:scheme="file" android:host="*" android:pathPattern=".*\\.myextension" />
</intent-filter>
我的提问
有一条毯子一套注册包含Android设备?
Is there a blanket set of intent-filters that register a specific activity with any file containing the desired file extension from anywhere on the Android device?
不知道你为什么要使用单独的意图过滤器时,你可以使用单个标签做到这一点。
Not sure why are you using separate intent-filters when you can do it using a single tag.
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="http" android:host="*"
android:pathPattern=".*\\.myextension" />
<data android:scheme="https" android:host="*"
android:pathPattern=".*\\.myextension" />
<data android:scheme="content" android:host="*"
android:pathPattern=".*\\.myextension" />
<data android:scheme="file" android:host="*"
android:pathPattern=".*\\.myextension" />
</intent-filter>
有可能是一个权限问题。即如果你的活动设置单独的任务来打开,那么将无法访问创建/文件被其他应用程序所拥有。 You'l必须设置意图的标志,使得它在同一个应用程序中打开。
There might be a permissions problem. I.E If your activity is set to open in separate task, then cannot access files created/owned by other applications. You'l have to set intent flags such that it opens in the same application.
