I am using butterknife library in my project. It works fine in when I build in Lollipop AOSP but the same code initializes nothing and so after that NPE is thrown in Marshmallow AOSP.
Here is the code:
public class ErrorLayoutViewHolder extends ViewHolder {
@Bind(R.id.error_content_container)
View errorContentLayout;
@Bind(R.id.error_message)
TextView errorMessage;
@Bind(R.id.retry_button)
View retryButton;
public ErrorLayoutViewHolder(final View itemView, View.OnClickListener retryListener) {
super(itemView);
retryButton.setOnClickListener(retryListener);
}
}
This is the parent class ViewHolder.java:
public class ViewHolder {
final public View itemView;
public ViewHolder(View itemView) {
this.itemView = itemView;
itemView.setTag(this);
ButterKnife.bind(this, itemView);
}
}
This is the stacktrace:
AndroidRuntime: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.setOnClickListener(android.view.View$OnClickListener)' on a null object reference

Line 38:
retryButton.setOnClickListener(retryListener);
What can be the problem?
