当我尝试使用:android.support.v4.widget.CircleImageView

        <android.support.v4.widget.CircleImageView
                android:id="@+id/picture"
                android:layout_width="100dp"
                android:layout_height="100dp"
                android:layout_gravity="center_vertical"
                android:src="@drawable/ic_bg" />

它让我的应用程序崩溃

将Android Studio升级到1.2.1.1或更高版本后,IDE无法打开库依赖关系对话框(Maven依赖关系)

它给出了这个错误:

Could not initialize class com.android.tools.idea.structure.gradle.MavenDependencyLookupDialog

这是一个错误,还是有些事情错了？
