Android Question MultiPhotoPicker Error

[Multiverse app]

Donmanfred's MultiPhotoPicker Wrap works perfectly in the example but throws this error when imports to my project-

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.aapkagarage.garage/com.nileshp.multiphotopicker.photopicker.activity.PickImageActivity}: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.app.ActionBar.setDisplayHomeAsUpEnabled(boolean)' on a null object reference

The error is in the line-

mpp.startPickerActivity(50,3)

Any help would be appreciated.
Thank you!

Check the manifest from the example

Check the manifest from the example

I did copy the manifest from the example as is.

Manifest-

AddApplicationText(<activity android:name="com.nileshp.multiphotopicker.photopicker.activity.PickImageActivity"/>)

and you app is using app compat and the theme from the example?

Yes, the app uses Appcompat.

This is how the theme is defined in the Manifest:

CreateResource(values, theme.xml,
<resources>
    <style name="MyAppTheme" parent="@style/Theme.AppCompat">
        <item name="colorPrimary">#41BAFF</item>
        <item name="colorPrimaryDark">#3D82F7</item>
        <item name="colorAccent">#ff4081</item>
        <item name="android:statusBarColor">#3D82F7</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
    </style>
</resources>
)

Same error

try to use it with the exact theme as in the example. Just to make sure
Make sure that the activity which is calling the picker also needs to be using

#Extends: android.support.v7.app.AppCompatActivity

As you told; the example is working for me too.

Otherwise you need to create a testproject which shoes the issue. But i guess i can´t help if it is related to the Theme you are using.
