I'm not using Evernote for programming purposes.
But, I can explain one solution.
Retrieve APK file and open it in Android Studio. Try to read Manifest.xml file.
So, the only place the app interacts with the other programs is this:
<activity
android:theme="@ref/0x7f0d022c"
android:name="com.evernote.note.composer.NewNoteAloneActivity"
android:configChanges="0x5a0"
android:alwaysRetainTaskState="true"
android:allowTaskReparenting="true"
android:windowSoftInputMode="0x2">
<intent-filter>
<action
android:name="com.evernote.action.VIEW_NOTE" />
<category
android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter>
<data
android:scheme="*" />
<action
android:name="com.evernote.action.CREATE_NEW_NOTE" />
<action
android:name="com.evernote.action.EDIT_NOTE" />
<action
android:name="com.evernote.action.NEW_SNAPSHOT" />
<action
android:name="com.evernote.action.NEW_PAGE_CAMERA_SNAPSHOT" />
<action
android:name="com.evernote.action.NEW_VIDEO_NOTE" />
<action
android:name="com.evernote.action.NEW_VOICE_NOTE" />
<action

<action

<action
android:name="com.evernote.action.SWAP_RESOURCE" />
<action
android:name="com.evernote.action.UPDATE_NOTE" />
<action
android:name="com.evernote.action.DELETE_NOTE" />
<category
android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter>
<action
android:name="com.evernote.action.CREATE_NEW_NOTE" />
<action

<action
android:name="com.evernote.action.DELETE_NOTE" />
<category
android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter>
<data
android:mimeType="*/*" />
<action
android:name="com.evernote.action.CREATE_NEW_NOTE" />
<action
android:name="com.evernote.action.EDIT_NOTE" />
<action
android:name="com.evernote.action.NEW_SNAPSHOT" />
<action
android:name="com.evernote.action.NEW_PAGE_CAMERA_SNAPSHOT" />
<action
android:name="com.evernote.action.NEW_VIDEO_NOTE" />
<action
android:name="com.evernote.action.NEW_VOICE_NOTE" />
<action
android:name="com.evernote.action.NEW_SKITCH_NOTE" />
<action
android:name="com.evernote.action.NEW_SPEECH_TO_TEXT_NOTE" />
<action
android:name="com.evernote.action.SWAP_RESOURCE" />
<action
android:name="com.evernote.action.UPDATE_NOTE" />
<action
android:name="com.evernote.action.DELETE_NOTE" />
<category
android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Which is the same as here described.

So, it seems your scenario is not possible.
