[Bug] `open` from `Dialog` plugin has issues with filters on android

[ppmpreetham]

While using open from the Dialog plugin, only windows allows the usage of filters, but not Android.

The following code snippet works on windows but not on android.
The issue being the filters.

const filePath = await open({
      filters: [
        {
          name: "HTML Files",
          extensions: ["html", "htm"],
        },
      ],
      multiple: false,
      directory: false,
});

while the below code snippet works fine on android

const filePath = await open({
      multiple: false,
      directory: false,
});

what's the behavior you're seeing when you add the filters? Does the dialog not apply the filter? Does it not open? Does it filter out every file?

It doesn't open the file picker on android when I have filters in my code. Meanwhile, it works perfectly on Windows

[FabianLars]

alright, thanks. Do you see any errors in the console or in Logcat? (you can access logcat in android studio if you use npm run tauri dev -- --open)

[ppmpreetham]

sadly, my PC crashes when i use android studio. But here's the console errors:

I think it's this LINE 07-02 21:00:58.953 16853 16853 E Tauri : No Activity found to handle Intent { act=android.intent.action.PICK typ=text/* (has extras) }

but the fact that my AndroidManifest.xml has this says otherwise

            <intent-filter>
                <action android:name="android.intent.action.PICK" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.OPENABLE" />
                <data android:mimeType="text/*" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.OPEN_DOCUMENT" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.OPENABLE" />
                <data android:mimeType="text/html" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.OPEN_DOCUMENT" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.OPENABLE" />
                <data android:mimeType="text/*" />
            </intent-filter>
            <intent-filter android:autoVerify="true">
                <action android:name="android.intent.action.GET_CONTENT" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.OPENABLE" />
                <data android:mimeType="*/*" />
            </intent-filter>

Maybe adding something around handling txt files as mentioned typ=text/* should be done?

Does anyone had found the solution already? I'm also facing the same issue.

I found using it without passing in filters to work properly

const filePath = await open({
      multiple: false,
      directory: false,
});
