title: What files do I need to push so that my changes are reflected in AOSP:?
body: <p>I am new to Android Open Source Project (AOSP) and trying to build my own version of Android OS. Currently, I am trying to learn to modify the codes of Android 10 and trying to find whether it works or not. To do that, I have firstly added a few codes in &quot;LocationManager&quot; class in the framework. I just added some Log code to output some message in the code like in the below:</p>
  <pre><code>Log.i(TAG,&quot;Lets see&quot;);
  </code></pre>
  <p>After that, I have built the code using the following code:</p>
  <pre><code>. build/envsetup.sh
  lunch sdk-eng aosp_x86-eng
  make sdk
  </code></pre>
  <p>What should be my next step if I want to see whether my changes works or not in an Genymotion emulator device? I have been trying to understand some online sources but not understanding them totally. I have also been trying to use &quot;adb sync&quot; command and finding out the emulator not working. I have also pushed some files as well but no result. I would be glad if someone can direct me in the right path. Thanks in advance for your kind assistance. Have a good day.</p>
