I have used your code to show local images with ZGrid, inside a onclick listener

Hello, same here. Do you already found the work around? If by any chance you are decided to switch to another lib, could I know what is it? Been wondering but still could not find much like with this zgallery. Thanks in advance.

Hi again, Finally, in my case, I add this in AndroidManifest and it doesn't crash:

    <activity
        android:name="com.mzelzoghbi.zgallery.activities.ZGridActivity"
        android:label="@string/title_activity"
        android:parentActivityName=".MainActivity"
        android:theme="@style/AppTheme.NoActionBar">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.myapp.MainActivity" />
    </activity>

    <activity
        android:name="com.mzelzoghbi.zgallery.activities.ZGalleryActivity"
        android:label="@string/title_activity"
        android:parentActivityName=".MainActivity"
        android:theme="@style/AppTheme.NoActionBar">
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.myapp.MainActivity" />
    </activity>

Well, hope it can help. ^^
