title: Upload to Google play with AdMob ads
body: <p>I have an App (I'll call "MyApp" on this post), finished and ready to upload. Also, I already have the code for show the ads.</p>
  
  <p>MyApp code, has the test device id:</p>
  
  <pre><code>AdRequest adreq = new AdRequest.Builder().addTestDevice("myid").build();
  </code></pre>
  
  <p>So, the first question is: If it's ready to upload, this will be change to:</p>
  
  <pre><code>AdRequest adreq = new AdRequest.Builder().build();
  </code></pre>
  
  <p>This is right?</p>
  
  <p>My other question is about the AdMob and the <strong>ad unit id</strong>.
  My ad unit id now, is reference to the app (I'll call AdMobApp) that I got in AdMob dashboard, this adMobApp was created with "Add your app manually" in AdMob. So, if I upload MyApp with the ad unit id of AdMobApp <strong>"manually added"</strong> it will working ok or not?  </p>
  
  <p>What the function "Search for your app" do? It put the ads automatically in your app or what?...  </p>
  
  <p>That process I don't understand, because, if I search the app(Assuming that MyApp is already on Google Play),  <strong>it will be created ANOTHER ad unit id</strong> So, what happens with the ad unit id that it's on the code?</p>
