java.lang.RuntimeException: Unable to start activity ComponentInfo by library

Question

I used this library https://github.com/liuguangqiang/IPicker

This is my code:

public void onClick(View view) {
        switch (view.getId()) {
            case R.id.ll_profile_pic_container:
                IPicker.open(getApplicationContext(), selectPictures);
                return;
            ...
    }

This is the error I receive when in activity com.liuguangqiang.ipicker.IPickerActivity I select my image from the gallery:

java.lang.RuntimeException: Unable to start activity ComponentInfo{rp.com.bmicalculator/com.liuguangqiang.ipicker.crop.CropImageActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.app.ActionBar.setHomeAsUpIndicator(int)' on a null object reference

I've followed all the directions I've provided from the library author ... Can the bug be in the library? No, because I've tested the app created by the same author and everything works perfectly ...

The app theme might be conflicting where you are using an ActionBar — Kartik Shandilya, Oct 12 '17 at 18:09

So, I installed the library you mentioned. Everything seems to work well. Maybe you are using AppTheme with no ActionBar?

Yes I using no ActionBar – Gugu Oct 14 '17 at 10:03
Well, if your 'IPickerTheme' parent is something like 'Theme.AppCompat.Light.NoActionBar' here comes your error. That is because IPickerActivity in library references the action bar. – Boris Kozyrev Oct 15 '17 at 18:21
