Gradle hatası çözüldü fakat layoutlarda bir değişme yok, aynı şekilde hatası devam ediyor.
The following classes could not be instantiated:
-*android.support.v7.widget.ActionBarContainer (Open Class, Show Exception, Clear Cache)
-*android.support.v7.widget.Toolbar (Open Class, Show Exception, Clear Cache)
-*android.support.v7.widget.ActionBarContextView (Open Class, Show Exception, Clear Cache)
-*android.support.v7.app.WindowDecorActionBar (Open Class, Show Exception, Clear Cache)
*Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE.* If this is an unexpected error you can also try to build the project, then manually refresh the layout.* Exception Details java.lang.NoSuchMethodError: android.support.v4.view.ViewCompat.setBackground(Landroid/view/View;Landroid/graphics/drawable/Drawable;)V **at android.support.v7.widget.ActionBarContainer.<init>(ActionBarContainer.java:64) **at java.lang.reflect.Constructor.newInstance(Constructor.java:423) **at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:727) **at android.view.LayoutInflater.rInflate_Original(LayoutInflater.java:858) **at android.view.LayoutInflater_Delegate.rInflate(LayoutInflater_Delegate.java:70) **at android.view.LayoutInflater.rInflate(LayoutInflater.java:834) **at android.view.LayoutInflater.rInflateChildren(LayoutInflater.java:821) **at android.view.LayoutInflater.inflate(LayoutInflater.java:518) **at android.view.LayoutInflater.inflate(LayoutInflater.java:426) **at com.android.layoutlib.bridge.bars.BridgeActionBar.<init>(BridgeActionBar.java:84) **at com.android.layoutlib.bridge.bars.AppCompatActionBar.<init>(AppCompatActionBar.java:59) **at com.android.layoutlib.bridge.impl.Layout.createActionBar(Layout.java:241) **at com.android.layoutlib.bridge.impl.Layout.<init>(Layout.java:153) Copy stack to clipboard
