title: How ro run emulator with aosp 10(Q) source code
body: <p>I downloaded the aosp 10(Q)source code with
  <code> repo init -u https://android.googlesource.com/platform/manifest -b android-10.0.0_r40</code> ,<br />
  <code>repo sync</code>. To run emulator, i started building the code with <code>source build/envsetup.sh</code>. I was confused to select which lunch option to run emulator. Here are the lunch options present :</p>
