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. ^^

@agungsus

@style/AppTheme.NoActionBar

Answer 5 · 2019-05-08T08:40:37.000Z

Hello,
Here is my style:

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>

    <item name="android:textColor">@android:color/black</item>
</style>

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

Hope it can help, cheers.

no improve.. same happening. with same error. @agungsus

Answer 7 · 2019-05-10T04:00:17.000Z

Hmm, not sure about that error, but do you already use 0.3.1 tag?
com.github.mzelzoghbi:ZGallery:0.3.1
If yes, I don't have any other idea.

Answer 8 · 2019-05-10T07:56:51.000Z

@agungsus yes it is 0.3.1.. problem still exist😟😔
