  <p>I know the new restrictions coming with android 10</p>

  <p>Does i need to use inCallService ? I don't want to be the default app for incoming call , just wake up my app only for my purpose .</p>
  <p>I don't know the technologies that can wake up android app like other messaging app like whatapps or messenger . A phone number don't need to be required .</p>
  <p>If someone has some clues to help me</p>
  <p>Thanks for all</p>
