REVISION SUMMARY
  When receiving a text share an attempt is made to show a toast but that results
  in an exception because the issuing threat is not running a looper.

TEST PLAN
  Without this patch applied Share a text with an android device using the plasmoid
  Result: No toast is displayed and in logcat you will get a:
  
    java.lang.RuntimeException: Can't toast on a thread that has not called Looper.prepare() exception
  
  With this patch applied again Share a text an android device using the plasmoid
  Result: The toast is actually displayed even when the activity is not in the foreground

REPOSITORY
  R225 KDE Connect - Android application

BRANCH
  make_toast_work
