null pointer exception when trying to launch helpstack

[quezak]

When trying to open HelpStack following the installation instructions, I get a null pointer exception following a call to getSupportActionBar() in your activity. I don't see any calls to setSupportActionBar in your activity, maybe is that the reason?

Testing on Android 5.1, app's minimum is 4.0.

My setup:

        helpStack = HSHelpStack.getInstance(context);
        HSEmailGear hsGear = new HSEmailGear("support@****", R.xml.test_faq_articles);
        helpStack.setGear(hsGear);

My launch line:

        HSHelpStack.getInstance(getActivity()).showHelp(getActivity());

Stack trace:

[...]

For me, getActivity() isn't recognized.

I'm launching this from a Fragment subclass (same way as the example
does), and getActivity() is a Fragment's method.
I also tried using the instance of my application as context, but the
result didn't change.

I still have the same issue described here

The problem may be related to the theme you are using. If you choose a theme like Theme.AppCompat.Light.NoActionBar for the entire Application, then you may have to add each HelpStack activity to your AndroidManifest file specifying a different Theme, enabling the ActionBar.

Can you tell me how to add each activity in the manifest @julianonunes

[julianonunes]

In styles.xml I've declared AppThemeWithActionBar:

    <style name="AppThemeWithActionBar" parent="Theme.AppCompat.Light">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:textColorPrimary">#ffffffff</item>
        <item name="android:textColorSecondary">#ffffffff</item>

    </style> 

Then in the AndroidManifest I've added

<activity android:name="com.tenmiles.helpstack.activities.HomeActivity"
            android:theme="@style/AppThemeWithActionBar"></activity>
        <activity android:name="com.tenmiles.helpstack.activities.ArticleActivity"
            android:theme="@style/AppThemeWithActionBar"></activity>
        <activity android:name="com.tenmiles.helpstack.activities.EditAttachmentActivity"
            android:theme="@style/AppThemeWithActionBar"></activity>
        <activity android:name="com.tenmiles.helpstack.activities.ImageAttachmentDisplayActivity"
            android:theme="@style/AppThemeWithActionBar"></activity>
        <activity android:name="com.tenmiles.helpstack.activities.IssueDetailActivity"
            android:theme="@style/AppThemeWithActionBar"></activity>
        <activity android:name="com.tenmiles.helpstack.activities.NewIssueActivity"
            android:theme="@style/AppThemeWithActionBar"></activity>
        <activity android:name="com.tenmiles.helpstack.activities.NewUserActivity"
            android:theme="@style/AppThemeWithActionBar"></activity>
        <activity android:name="com.tenmiles.helpstack.activities.SectionActivity"
            android:theme="@style/AppThemeWithActionBar"></activity>

@quezak @julianonunes
Issue has been fixed,
You can use the code from the master branch.

No need to edit the theme and the Manifest.
We have made getSupportActionBar() check in HSActivityParent.
that will handle this issue.
