ImagePickerActivity throws NullPointerException about poly-picker HOT 6 CLOSED

The crash is in your setupActionBar() method. Probably your theme has no ActionBar but you are trying to get a handle to it. Possible?

from poly-picker.

I was having the same issue. Turned out my application base theme was AppCompat, which was causing issues. Changed the theme for particular activity and it worked. Hope it helps someone else.

This is step by step guide to change particular activity theme.
In styles.xml, add this lines

<style name="HoloTheme" parent="@android:style/Theme.Holo.Light">

</style>

In AndroidManifest.xml change these lines to these

<activity android:name="nl.changer.polypicker.ImagePickerActivity"
          android:theme="@style/HoloTheme"/>

No more crash after that.

@anuragdadheech, @azam3d are both correct. In my case:

<activity android:name="nl.changer.polypicker.ImagePickerActivity"
          android:theme="@style/AppTheme"/>
