This problem is not because of JDK 1.8 or 1.7, Its due to dependencies. Please check your Gradle Dependencies.

I have faced similar issue, in my case the problem was occurred due to Facebook dependency

dependencies { ... ... ... ... ... //Commented the following one compile 'com.facebook.android:facebook-android-sdk:4.0.0' } after commenting the above line everything was normal
