Use resolveActivity To Check if Intent Can Be Handled

Question

I am trying to disable the camera launch button in my app if the camera intent cannot be handled by the device. I am targeting Android R (11). The code that I have so far is this

  val packageManager: PackageManager = requireActivity().packageManager

  val captureImage = Intent(MediaStore.ACTION_IMAGE_CAPTURE)
  if (captureImage.resolveActivity(packageManager) == null) {
    isEnabled = false
  }

The issue that I am having is that when I implement this code the camera launch button is always disabled even on devices that support it. I am not sure why it is doing this other than that maybe I need to add package-visibility into the manifest file but I am unsure how that all works as the documentation isn't the best when it comes to examples. Any help or guidance would be greatly appreciated.

You can add queries like this in your manifiest

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="app.android">

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

    <queries>
        <package android:name="com.whatsapp" />

        <intent>
            <action android:name="android.media.action.IMAGE_CAPTURE" />
        </intent>
        <intent>
            <action android:name="android.intent.action.DIAL" />
        </intent>
    </queries>

     <application
      ...
     </application>
</manifest>

Would you mind editing your answer to explain the queries children? – Alex Lowe Jun 09 '21 at 05:13
Umm.. for any android dev they are very clear. No need to explain which is already self-explanatory and I think it is out of the scope of this question. – OhhhThatVarun Jun 09 '21 at 05:15
What would be the intent for access to contacts? – Alex Lowe Jun 09 '21 at 17:01
There are no queries for contacts it's permission. So you would need a read contacts permission. – OhhhThatVarun Jun 09 '21 at 18:14
