inklusive <uses-permission android:name=“android.die Genehmigung.INTERNET" /> in manifest-Fehler verursacht
Habe ich schon angefangen zu lernen, über die Vernetzung und arbeiten bereits an einer android-Anwendung zu testen, was ich gelernt habe. Nun, ich habe zusammen mit einem tutorial auf dem web, aber etwas seltsames zu passieren scheint. Das Programm hat eine schwerwiegende Ausnahme, wenn ich auch die Berechtigung für den Internetzugang, sondern gibt mir eine EACCES verweigert Fehler, wenn ich nicht zählen.
Hier ist mein code (halten Sie im Verstand dies ist eine Menge von mir nur Experimentieren und ausprobieren):

}Und hier sind die zwei unterschiedliche Manifest-Dateien:
