Analysefehler beim Installieren der .APK -Datei ⇐ Android

[Anonymous]

Ich lade eine .APK -Datei vom Server mit DownloadManager nach dem Herunterladen herunter, wenn ich versuche, die App manuell zu installieren. Es gibt Parse -Fehler mit einer Nachricht "Es gibt ein Problem, das das Paket analysiert". Kein Problem mit der minsdkversion und ich habe bereits auf unbekannte Quellen nachgefragt. public class UpdateCheckerService extends Service {
