Android

Current Behavior

I need to test if the Twitter/X and Facebook apps are installed.

On iOS, the code provided below works as expected and returns true if both apps are installed.
(In order to make this work on iOS, I also needed to add the LSApplicationQueriesSchemes to Info.plist containing an array of strings including twitter and fb.)

On Android however, the code below returns false for both apps, despite them being installed.

I have tried adding the required entries to AndroidManifest.xml to allow querying the packages:

<queries>
    <package android:name="com.twitter.android" />
    <package android:name="com.facebook.katana" />
    <intent>
      <action android:name="android.intent.action.VIEW"/>
      <data android:scheme="twitter"/>
    </intent>
    <intent>
      <action android:name="android.intent.action.VIEW"/>
      <data android:scheme="fb"/>
    </intent>
  </queries>
  

I have also tried adding this permission :

<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES" tools:ignore="QueryAllPackagesPermission" />

Expected Behavior

I expect the result to be true when the apps are installed on the device.

What am I missing?

Code Reproduction

import { AppLauncher } from '@capacitor/app-launcher';

AppLauncher.canOpenUrl({ url: 'twitter://timeline' }).then(data => {
        console.log('AppLauncher : Is Twitter/X installed? ', data.value);
});

AppLauncher.canOpenUrl({ url: 'fb://feed' }).then(data => {
        console.log('AppLauncher : Is Facebook installed? ', data.value);
});

This issue needs more information before it can be addressed.
In particular, the reporter needs to provide a minimal sample app that demonstrates the issue.
If no sample app is provided within 15 days, the issue will be closed.

Please see the Contributing Guide for how to create a Sample App.

Thanks!

I have provided a simple code sample above.

Please also refer to the Example Code provided in the actual documentation for this official plugin.

Simply replace the URLs with the ones that I have clearly provided above.

Sorry, but I do not understand what else you need?

This plugin does not work as documented, as I have clearly explained above.

(The documentation fails to even mention the additions to Info.plist I had to add for this to work on iOS)

I can't believe how many hours I've wasted trying to make this work as documented.

[jcesarmobile]

we need a full sample app that we can build and run to reproduce the issue

the additions to the Info.plist are documented here

Please find a full sample app here

https://github.com/kosso/applauncher-issue

This is built for iOS and Android and will demonstrate that the iOS version works and the Android version doesn't.

Additional information and testing a new method :

I have had a go at creating an internal custom 'Utils' plugin for Android to try a different method than the way that the app-launcher plugin tries to perform canOpenUrl() ...

.. and it works!

Please see the custom-utils-test branch of my sample app for testing and reference here :

https://github.com/kosso/applauncher-issue/tree/custom-utils-test

Here is the source to my test 'Utils' Android plugin, containing a method canOpenURLTest()
