Fehler, wenn ich Bild aus der Galerie mit Gerät, aber nicht mit Emulator

Question

Warum, wenn ich Bild aus der Galerie mit meinem Gerät wählen Fehler, aber wenn Emulator nicht verwenden? Anmerkung * der Emulator api mit 17, und mein Gerät api mit 19

und nachdem ich Fehler bekommen habe ich versucht, diesen Teil Code aus WC_Activity.java entfernen und es funktioniert normalerweise

, wie ich das beheben kann?

if (Build.VERSION.SDK_INT < 11) 
       realPath = RealPathUtil.getRealPathFromURI_BelowAPI11(this, data.getData()); 

       // SDK >= 11 && SDK < 19 
      else if (Build.VERSION.SDK_INT < 19) 
       realPath = RealPathUtil.getRealPathFromURI_API11to18(this, data.getData()); 

       // SDK > 19 (Android 4.4) 
      else 
       realPath = RealPathUtil.getRealPathFromURI_API19(this, data.getData());

Answer 1

Versuchen Sie, Intent.ACTION_PICK anstelle von Intent.ACTION_GET_CONTENT zu verwenden, um ein Foto aus der Galerie auszuwählen.
