Question

Probieren Sie den folgenden Code, um eine Anwendung auszuführen, aber den folgenden Fehler erhalten. Manifest Merge mit mehreren fehlgeschlagen Fehler, siehe Protokolle ". Ich habe einige Änderungen in der App-Gradle-Datei vorgenommen, da die Anwendung die Verwendung von "CardView- und Recycler-Ansicht" beinhaltet (Änderungen wurden bei einigen Fragen im Stackoverflow empfohlen). Anhängen aller App-Dateien unten. Kann mir bitte jemand dabei helfen? Gradle Console:

If you are using NDK, verify the ndk.dir is set to a valid NDK directory. It is currently set to C:\Users\Sumeet\AppData\Local\Android\Sdk\ndk-bundle. 
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

Answer 1

Sie versuchen, mehrere Versionen des Android Support Library zu verwenden:

• compile 'com.android.support:appcompat-v7:25.3.1'
• compile 'com.android.support:design:22.2.0'
• compile 'com.android.support:recyclerview-v7:+'

Verwenden Sie die gleichen Version für allecom.android.support Artefakte. Und diese Version sollte nicht + sein. Angesichts dieser drei Zeilen würde ich mit 25.3.1 gehen.
