Android-JAVA - Service-Rückkehr OutOfMemoryError Ausnahme nach einiger Zeit

Ich entwickle meine erste android app. Ich habe erstellt eine Service-Klasse, die Rolle ist zu prüfen, ob neue Informationen auf einer externen Webseite. Der HTTP-request-und service-arbeiten als ich sollte, aber nach einer Weile bekomme ich diese OutOfMemoryError.

Jemand in der Lage, um zu sehen, wo die Service-sammeln Sie alle, dass der Speicher?
