Ich versuche RecyclerView in meinem Projekt zu verwenden, aber weil wir einige schlechte Proxies haben, kann ich nicht leisten, kompilieren "com.android.support:recyclerview-v7:+" zu meinem build.gradle hinzufügen, weil der Download ist sehr langsam. Für die anderen Bibliotheken habe ich einfach die .jar-Dateien zum Ordner 'libs' des Projekts hinzugefügt und in build.gradle habe ich compile files('libs/android-support-v7-recyclerview.jar'). Ich habe die .jar aus dem Android SDK unter /extras/android/support/v7/recyclerview/libs. Ich habe die android-support-v4 Bibliothek von der gleichen Stelle und es funktioniert gut.Android Verwenden Sie RecyclerView mit lokalen Recyclerview-Bibliothek, anstatt es aus dem Maven Repo laden
Die App wird erstellt, aber zur Laufzeit bekomme ich eine NoClassDefFoundError.
compile "com.android.support:support-v4:21.+"
compile "com.android.support:gridlayout-v7:21.+"
compile "com.android.support:cardview-v7:21.+"
compile "com.android.support:recyclerview-v7:+"
Mit diesen diejenigen:
compile files('libs/android-support-v4.jar')
compile files('libs/android-support-v7-gridlayout.jar')
compile files('libs/android-support-v7-cardview.jar')
compile files('libs/android-support-v7-recyclerview.jar')
und das Hinzufügen der 4 JAR-Dateien aus dem gleichen SDK Application/libs (Das Verhalten kann durch das Ersetzen in Application/build.gradle diese Zeilen in /samples/android-21/ui/views/RecyclerView gefunden mit Googles RecyclerView Probe repliziert werden Sie müssen den Ordner erstellen, da er keinen hat).
Das vollständige Fehlerprotokoll von der Google-Probe erzeugt:

ich auch versucht, wie die Leute vorgeschlagen, die classes.jar in extras/android/m2repository/com/android/support/recyclerview-v7/23.3.0/recyclerview-v7-23.3.0.aar gefunden zu verwenden, aber das Ergebnis war genau das gleiche.
Irgendwelche Hinweise darauf, was ich vermisse/falsch mache?
Ich denke, die 'jar' Datei ist nicht genug. Sie müssen stattdessen die Datei 'aar' (recyclerview-v7-23.3.0.aar) verwenden. http://stackoverflow.com/questions/16682847/how-to-manual-include-external-aar-package-using-new-gradel-android-build-syst – Blehi
@Blehi: Ja, das war es. Dank dafür! Du kannst deinen Kommentar als Antwort posten, damit ich ihn annehmen kann! Stellt sich heraus, die JAR-Datei hatte den Code, aber es hatte nicht die Ressourcen, so dass die Verwendung der AAR stattdessen behoben. – Scorpio
