Nothing looks incorrect in your directory. Can you please download the following test icons and drop those into your project for testing? I just took the Corona logo and tinted them blue:
first of all i want thank you, and appriciate your help.
ok so i have tested these icons in my project, first it didn’t work on my samsung S3, then i tested on Sony xperia it worked on that device.
My phone is rooted and cyanogenmod is running on my device. so i was wondering why launcher icon doesn’t appear on my device. is that because of custom ROM ?
Corona SDK does not support Jailbroken or Rooted devices. Testing stock Android is tough enough. There is no way we can possibly work with rooted devices. Too many variables.
