durchgesickert ServiceConnection Android text-to-speech

Habe ich eine app, die mit text-to-speech einschalten. Alles scheint zu funktionieren perfekt und ich habe keine Probleme beim ausführen der app. Jedoch, jedesmal, wenn die app startet, bekomme ich ein LogCat Fehler, der sagt, ich habe eine durchgesickert ServiceConnection auf meinen text-to-speech. Obwohl dies nicht ein problem verursacht in der Funktion zurzeit bin ich Angst davor, was meine in der Zukunft passieren, wenn ich weiterhin um den Fehler zu ignorieren. Ich vermute, es ist einfach nur verlegt Codierung, aber ich habe nicht die Erfahrung zu erkennen, was ist fehl am Platz. Ich habe die LogCat und die problematische java.
