[General Topics] Laelson:
This mod is an adaptation for ROMs that does not have RomControl. Link of the original topic at the end of the post.

First I made the modification on TouchwizHome this way:

Go to: Touhcwizhome_2016\smali\com\android\launcher2\PagedView.smali

Find this line:

.method public setDefaultTransitionEffect(Lcom/android/launcher2/PagedView$TransitionEffect;)V

It replaces the complete method with this here:

.method public setDefaultTransitionEffect(Lcom/android/launcher2/PagedView$TransitionEffect;)V
.locals 4
.param p1, "transitionEffect" # Lcom/android/launcher2/PagedView$TransitionEffect;

.prologue
.line 3487

.line 3488
return-void
.end method

Okay, I've recompiled.

Now I have to make the modification in SecSettings2 (In the original guide, it stays in the RomControl)

Go to: SecSettings\res\values\strings.xml add the text below at the end (before /resources)

<string-array name="tw_effect_entries">
<item>None</item>
<item>Cascade</item>
<item>Outer cube</item>
<item>Inner Cube</item>
<item>Carousal</item>
<item>Plain</item>
<item>Conveyor</item>
<item>Card</item>
</string-array>
<string-array name="tw_effect_values">
<item>1</item>
<item>2</item>
<item>3</item>
<item>4</item>
<item>5</item>
<item>6</item>
<item>7</item>
<item>8</item>
</string-array>

Go to: SecSettings\res\xml\display_settings.xml and add this text in the end, before </ PreferenceScreen>:

ListPreference android:entries="@array/tw_effect_entries" android:title="Touchwiz Transition Effect" android:key="tw_page_effect" android:defaultValue="1" android:entryValues="@array/tw_effect_values" />

After that, I recompiled. The option appears in Settings> Display. But even selecting one of the effects did not work. I need help to finish this mod. Please help me!
