title: The problem about Google Play's target API level requirement
body: <p>From the article <a href="https://developer.android.com/distribute/best-practices/develop/target-sdk" rel="nofollow noreferrer">https://developer.android.com/distribute/best-practices/develop/target-sdk</a>, </p>
  
  <p>Google Play will require that new apps target at least Android 8.0 (API level 26) from August 1, 2018, and that app updates target Android 8.0 from November 1, 2018.</p>
  
  <p>The following code is from my app.</p>
  
  <p>1:  Does it mean that targetSdkVersion must be greater than or equal to 26 ?</p>
  
  <p>2:  Does it mean that minSdkVersion can be  21 ?</p>
  
  <p><strong>Code</strong> </p>
  
  <pre><code>defaultConfig {
  
          applicationId "info.dodata.mirror"
          minSdkVersion 21
          targetSdkVersion 26
          versionCode 9
          versionName "1.09"
          archivesBaseName = "My-V" + versionName
      }
  </code></pre>
