Android Studio: my sms app is not one of the options for default SMS app

Question

I'm new to android app development so bear with me.

I've made a SMS app and are now trying to give the user the option to make the app the default SMS-app. I've read that the app is supposed to be able to do everything the standard SMS app can before it can become the default SMS-app. The functions the app can is: send SMS and receive and read incoming SMS. I've also made the broadcastreceivers for receiving MMS and the service for quick response. These do not do anything but is there so my phone thinks that the app is capable of everything an SMS app is supposed to do.

I've made it so when the user opens the app, the app checks if the app is the default SMS-app. If not, it will ask the user if the user wants the set the app as default. The problem is that my app isn't showing up as one of the options for default SMS apps. I think it's because of the phone don't think the app is capable of everything an SMS app needs to do, and therefore isn't showing it as one of the options.

Heres my Manifest file:

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.imessages">

        <meta-data
            android:name="preloaded_fonts"
            android:resource="@array/preloaded_fonts" />
    </application>

</manifest>

Again I'm new to this so i've included absolutely everything into the Manifest that will make my app look like it's a SMS app. There might be some stuff in there that shouldn't be there. Thanks in advance.

Answer 1

So I managed to fix it. Thanks for your help. I think I know what fixed it (thanks Pawel) here's my explanation:

I removed the exported = "true" and enabled = "true" since i found out that they are irrelevant, at least for my project. This does not have anything to do with the problem. I did change the .MySMSReceiver from SMS_RECEIVED to SMS_DELIVER which Pawel told me to. I did and at first it didn't work but now it works. Must have been my mistake sorry. Thanks for the help! And sorry for messing up on your answer Pawel.
