Android NoClassDefFoundError nach Constraint Layout

Question

Zugabe begann ich habe java.lang.NoClassDefFoundError: für zufällige Klasse bekommen und dass Klassenänderungen auf jeder meiner Mitspieler Maschine und es geschieht nur für 5.x Geräte testeten wir auf 6.0 und 7.0 aber alles funktioniert es gut. Diese begann nach Zugabe geschieht 'com.android.support.constraint:constraint-layout:1.0.2' Wir entscheiden mit Constraint-Layout in App zu starten, und seitdem sind wir immer diese Fehlermeldung

Update: Ich habe die Einschränkung entfernt Layout von XML und entfernt diese Zeile: compile 'com.android.support.constraint: constraint-layout: 1.0.2' Und jetzt App funktioniert gut.

Vier Gründe sind NoClassDefFoundError in android erzeugen:

1) The class is not available in Java Classpath. 

2) You might be running your program using jar command and class was not defined in manifest file's ClassPath attribute. 

3) Any start-up script is overriding Classpath environment variable. 

4) Because NoClassDefFoundError is a subclass of java.lang.LinkageError it can also come if one of it dependency like native library may not available.
