Register Activity To Open Any File With Certain Extension
android, android-intent
Solution
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>
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.
Problem
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. 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! Here is my 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> ``` My Question 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?
