Okay,i have gone through almost every miui theme available and most put their own system notifications in and.... i for the life of me can not find a custom sms icon to add to my theme! every theme has the bubble with the 3 black dots in it. Can someone explain why? or tell me what the name should be in the framework so i can change this to my own Ex.(stat_notify_???) sms i guessing...... IDK
Ok I have changed my SMS notification icon and here is what I did.
In a MIUI theme you need to have a folder named "com.android.mms" (if you dont just create one).
In that folder you need the folders "res" and "drawable-hdpi"
In the "drawable-hdpi" folder are the .png files that can alter the mms application, so just copy the .png file of your choice to the "drable-hdpi" folder TWICE and name one stat_notify_mms and the other stat_notify_sms. It is the same icon for both but with different names. That may not be necessary but it works for me the new icon shows up in my status bar for new text messages.
Just to recap you need to have your .png files in com.android.mms/res/drawable-hdpi
Then just zip the theme folders such as description, framework, preview, com.android.launcher and of course com.android.mms into one .zip file and add it to your theme folder on sd card then apply through the theme manager.
That does it for me, but if anyone knows how to change the Gmail notification icon...I know it is named stat_notify_gmail but can't quite figure out where it should go.
