Android 5.0 emulator showing Storage space running out -

I'm just updating Android SDK to version 21 and am trying to start the emulator. I'm using Nexus 4 with CPU Intel Atom (x86) 768 RAM and 524 internal storage. The emulator starts right but it shows an error message, "storage space is running" and it is very slow I tried to increase the RAM but did not work. What can be the problem?

You have to go to your android folder eg. OSX ~ / .android / avd / {YOUR_AVD_NAME} and edit the file config.ini.

Just disk.dataPartition.size = YOUR_SIZE

For example disk.dataPartition.size = 1G

Then you may have to erase your emulator's disk.
