Unable to open PDF file on Android 11 - targetSdkVersion 30

[Noitham]

Hello,

I've been using this library (the former repo) for quite some time in order to open PDF files.
Recently, I've updated Android's targetSdkVersion to 30, and I've noticed the actionViewIntent function is not functioning on Android 11.
Using it as: android.actionViewIntent(filePath, `application/pdf`);

No error or whatsoever is thrown, so not really possible to apport more specific information.

Currently, asking for these permissions on AndroidManifest.xml:

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

And have bothpreserveLegacyExternalStorage & requestLegacyExternalStorage set as true.

Using latest "react-native-blob-util": "0.13.15" version

Has somebody else faced this issue after updating?
Am I missing some specific settings?

Thanks in advance.

EDIT:

Paths were I've tested to open the .pdf from (emulator):

/data/user/0/com.{app_bundle}/cache/{....}.pdf
/storage/emulated/0/Documents/{....}.pdf

actionViewIntent is in general still working, also with pdf. Using it in production myself.

You're using the old library? This one did not trigger a promise rejection if no app to open the pdf is installed. React-native-blob-util will reject the promise and thus give you some information.

The reason I'm writing this is, that I had the same behavior you're describing on devices which didn't have a proper app to open the file type I wanted to open. So please check if you have any app installed that can open a pdf. (Not just open but react on actionviewintent, so basically opens if you click on a pdf in e.g. a file manager)

Thanks for the quick response @RonRadtke.
I've made sure of it, and yes, I'm making use of the latest version (0.13.5) of the react-native-blob-util library.

Yesterday I tested on an emulator, so the option of not having an app could be there, but today I've been able to test it on an Android 11 device which has PDF apps and where we're able to open the PDF if we access it from a file manager.

The result is no feedback other than null is provided when logging the
await ReactNativeBlobUtil.android.actionViewIntent(filePath, `application/pdf`) function.

Issue solved!

Adding:

    <queries>
        <intent>
            <action android:name="android.intent.action.VIEW" />
            <data android:mimeType="*/*" />
        </intent>
    </queries>

on the AndroidManifest.xml file fixed it for me 👍

Glad to hear. Then I close the issue here
