App stürzt aufgrund von java.lang.SecurityException @
Ich arbeite an dem Projekt, Fotos oder Bilder aus der Galerie aufzunehmen und in der Recycler-Ansicht anzuzeigen. Die App funktioniert in Android-Lollipop einwandfrei, stürzt jedoch in Marshmallow One ab, sobald auf die Kamerataste geklickt wird.
Caused by: java.lang.SecurityException: Permission Denial: writing com.android.providers.media.MediaProvider uri content://media/external/images/media from pid=1983, uid=10060 requires android.permission.WRITE_EXTERNAL_STORAGE, or grantUriPermission()

Ich habe viele Antworten überprüft, kann sie aber nicht reparieren. Bitte helfen Sie! Auch während die Auswahl von Bildern aus der Galerie zeigt leere Karte in Marshmallow (kein Bildinhalt), heißt esStellen Sie sicher, dass der Cursor korrekt initialisiert ist, bevor Sie darauf zugreifen. während es funktioniert gut in Lollipop ein. Alle Vorschläge werden sehr geschätzt.
