How fast can you adapt Android for grandma?

Question

Android

Good day to all.
An unnecessary smartphone on Android was lying around, there is a lot of news on the network how programmers, with the help of their knowledge, made it easier to use a computer or smartphone. I want to adapt a smartphone for my grandmother so that it would be enough for her to say "Ok, Google" and the call would take place via Telegram. I remembered that there is CyanogenMod, will it help me?
Thanks in advance!

Answer 2

the set of commands that can be written in the intent of your application is limited.
I added this to my app

<intent-filter>
                <action android:name="android.intent.action.SEND" />
                <category android:name="com.google.android.voicesearch.SELF_NOTE" />
                <data android:mimeType="*/*"/>
            </intent-filter>

Ok, Google, Note blah blah blah
If the action is not selected by default, a dialog appears, and to which application to transfer the
recognized text.
In my opinion, there will be problems with the command to make a call, most likely your application should be set as the default dialer.
