Android Studio unterstützt zwei Fehler in AndroidManifest.xml:

auf platformBuildVersionCode = "23" und auf platformBuildVersionName = "6.0-2438415"

beide Angabe „Attribut fehlt das Android Namespacepräfix“

Ich weiß nicht, ob die Fehler in Zusammenhang stehen, aber wahrscheinlich nicht gut sowieso ..

Dieses Projekt nicht mit gradle gebaut wird, und ich Ich weiß nicht, wie ich es hinzufügen soll.

Answer 1

Der Fehler besagt, dass Ihre IDs platformBuildVersionCode und platformBuildVersionName ein Namespace fehlen. Alle XML-Identifiers einen Namensraum durch den Schlüssel gefolgt haben, wie android:name

Futhermore die Tasten sind nicht gültige Bezeichner für die Build-Version und den Namen, es ist

android:versionCode="integer" 
android:versionName="string" 

wie hier erwähnt: https://developer.android.com/guide/topics/manifest/manifest-element.html

Um Gradle zu Ihrem Projekt hinzuzufügen, können Sie das Projekt in Android Studio importieren.

Und Ihr Fehler wird durch eine fehlende Klasse verursacht. Sie sollten Ihr XML-Layout (nicht das Manifest) überprüfen und die Klassenkennung mit der Klasse in Ihrem Code vergleichen.

Answer 2

In Ihrem PC.

Goto Projektordner Projekt>build Ordner &

Projekt> src>build Ordner löschen. Dann wieder aufbauen project.Project
