Android Question Registering custom file extensions

Hi

I would like my app to open when the user clicks on a text file (email attachment) with a custom file extension (.cgh)

I have tried many solutions, all with the same issue - When I click on the .cgh file, I get the option to open it with my app. But having done that, my app now opens when I click on any file with an unknown file extension (say .arp)

Is there any way I can stop this behavior?

I would like my app to only open if the user clicks on a .cgh file.

Alternatively, is there any way to have my app come up as an option when I click on a .cgh file, but for this choice to not be remembered?

The relevant bit in my manifest is:

B4X:
AddActivityText(moreInfo,
        <intent-filter >
           <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
         <data android:mimeType="*/*" />
            <data android:pathPattern="*.cgh" />
        </intent-filter>
)

Thank you
Andrew

try it with
B4X:
<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:scheme="file" />
    <data android:host="*" />
    <data android:pathPattern=".*\\.cgh" />
  </intent-filter>

Hi Don

Unfortunately that code does not work - the app does not come up as an option when I click on the .cgh file......

Tried as you suggested. Unfortunately that code does not work - the app does not come up as an option when I click on the .cgh file...…

B4X:
AddActivityText(moreInfo,
    <intent-filter >
       <action android:name="android.intent.action.VIEW" />
       <category android:name="android.intent.category.DEFAULT" />
       <data android:scheme="file" />
       <data android:host="*" />
       <data android:mimeType="*/*" />
       <data android:pathPattern="*.cgh" />
    </intent-filter>

Are there any other options?

Behavior with other ‘commercial’ applications (pdf files, etc) seems to work with no issues

Failing this, what is the best way of importing a text file of data (arriving in an email) into an app? Maybe save the file on the device, and I guess there is some way of opening a file from within an app using b4a?

Thank you for any thoughts...…..

Thank you. ContentChooser is working well.

But I hope Google 'fixes' Intents from the manifest file - I cants imagine the previously working Intent method of file association has been changed 'on purpose'.
