How to get Transparent android activity over the lockscreen?

I want my activity to show up on lockscreen(which is working fine). but i want to get that activity transparent..

I tried 2 methods both are not allowing my activity to show on lockscreen.

Method 1

android:theme="@android:style/Theme.Translucent.NoTitleBar"

Method 2

<style name="Theme.Transparent" parent="android:Theme">
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:backgroundDimEnabled">false</item>
</style>

Both are not allowing to show the activity on lockscreen.



Is there any method you know?
