Ich bekomme ständig eine Sicherheitsausnahme, wenn ich versuche, eine andere Aktivität als meine MainActivity zu starten, Code funktioniert gut, wenn ich meine MainActivity starte, aber löst eine Ausnahme aus, wenn ich versuche, eine andere Aktivität als MainActivity zu starten, ich habe nach Antworten gesucht und eine Lösung gefunden, um --android: exported = "true" - in meinem Manifest zu platzieren, aber das hilft nicht dem Problem, vor dem ich stehe Hilfe wird bis jetzt sehr geschätzt.Java.lang.securityException: Berechtigungsverweigerung: Start Absicht

* bekam eine Lösung -Android zu setzen: exportiert = „true“ - in meinem Manifest * ... aber Sie setzen es in einem zufälligen Ort ... was war die vollständige Antwort das gefunden? sagt es, dieses Attribut in '' Element zu setzen? Hat '' Element '' android: exportiert 'überhaupt? –

Dank Selvin, es geht durch meine Tag, es funktioniert jetzt gut. Ich schätze, du bekommst keine Antworten, immer gut, um ein wenig zu graben, mein Dank. –
