 <p>The system NAND flash for the emulator has run out of space. Your host system D: is not the issue, but for some reason the system.img file that represents a NAND flash for the emulator is full. You can try creating a new emulator, or doing a factory default reset in the emulator to clean it up. To do this, either issue a Factory Data Reset inside Android under Settings -> Privacy, or start the emulator from the command-line:</p> <pre><code>android list avd emulator -avd My_Avd_Name -wipe-data </code></pre> <p>The first command list all Android Virtual Devices. You need the name for the second command. The emulator should not already be running. A third option would be to delete the disk images located under your Windows profile. Under your profiles, it's <code>.android/avd/My_Avd_Name.avd</code> You should only need to delete <code>userdata-qemu.img</code> and maybe <code>cache.img</code>. You can try deleting other image files if necessarily, but note, <code>sdcard.img</code> won't be re-created automatically. You need to run <code>mksdcard</code> from the command-line.</p>
