i use public class but can't mock instance

See original GitHub issue
public class MyBean {
    public String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

@vipheyue I think mockito-android should be declared like dexmaker was, i.e. with androidTestCompile scope.

dependencies {
    testCompile 'junit:junit:4.12'
    testCompile 'org.mockito:mockito-core:2.+'
    androidTestCompile 'org.mockito:mockito-core:2.+'
    androidTestCompile "org.mockito:mockito-android:2.+"
}
