esecuzione Android 2.1.2 Studio, Windows 7.Errore di gonfiaggio classe - NestedScrollView - classe non trovato
ho sostituito uno ScrollView con un NestedScrollView e adesso mi sto
android.view.InflateException : Binary file XML linea # 2: Errore classe di gonfiaggio NestedScrollView
java.lang.ClassNotFoundException: non trovare la classe "android.view.NestedScrollView" sul percorso: /data/app/com.assemblyguide.remote -48 .apk
... quando chiamo SetContentView() su quel file XML. Non l'ho capito quando avevo solo un ScrollView.
Ho provato a pulire e invalidare la cache e la ricostruzione. L'XML sembra così. . .

Che cosa significa questo errore e come lo risolvo?
Grazie, ma io ancora non capisco: perché non lo fa un errore in questo flag l'XML al ** tempo di costruzione **? Inoltre, qual è la libreria di supporto, cioè qual è la differenza tra la libreria di supporto e solo le normali classi di Android? – user316117
La libreria di supporto è un backport di alcune funzionalità di Android aggiunte in seguito. Ad esempio, il widget 'Toolbar' è stato aggiunto in v21. Ciò significa che se volessi utilizzare una barra degli strumenti nella tua app, il tuo minSdk avrebbe bisogno di essere 21. C'è un'implementazione di 'android.support.v7.widget.Toolbar' che ci permette di usare la barra degli strumenti con un minSdk di 7. In re: build time xml error, non sono sicuro, ma se utilizzi Android Studio, puoi fare clic sulla scheda "Design" e mostrerà un errore. – chessdork
