ro.sf.lcd_density must be defined as a build property

Question

While running the application on the emulator, I have got those errors. How can I solve it so that my program will be more reliable ?

error:

Answer 1

This has nothing to do with your application, it's just noise from the emulator. Check on a real device and you won't see this message anymore.

Answer 2

I was getting this log message when had an icon in /res/drawable. I moved it into /res/drawable-hdpi and deleted /res/drawable and the log message went away.
