title: Use Android-Studio on 32 bit Ubuntu
body: <p>I need to use Android-Studio on my 32 bit machine. I have Ubuntu installed, but I keep having issues even for execute "Hello world" on my phone. This is what I did:</p>
  
  <ul>
  <li>I changed default JDK location with my JDK location</li>
  <li>in the gradle file of the app I changed buildToolVersion from 25 to 23.0.1</li>
  <li>in the gradle file of my app i changed classpath 'com.android.tools.build:gradle:2.3.1' to classpath 'com.android.tools.build:gradle:2.2.1'</li>
  <li>I put compileSdk, targetSdkVersion and minSdkVersion to 23 in the gradle file</li>
  <li>I changed compile 'com.android.support:appcompat-v7:26.+' with compile 'com.android.support:appcompat-v7:23.+'</li>
  </ul>
  
  <p>now I am having this problem:</p>
  
  <pre><code>Error:(11) No resource identifier found for attribute 'roundIcon' in package 'android'
  </code></pre>
  
  <p>and if I try to remove the roundIcon attribute from the manifest, it appears again, so I think the manifest is generated by something else which put the attribute roundIcon, which is not supported on API 23. Someone, please help me coding Android on 32-bit machine
  This is my Manifest under the tag Application:</p>
  
  <pre><code>&lt;application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme" &gt;
      &lt;activity android:name="com.example.root.gbu.MainActivity" &gt;
          &lt;intent-filter&gt;
              &lt;action android:name="android.intent.action.MAIN" /&gt;
  
              &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
          &lt;/intent-filter&gt;
      &lt;/activity&gt;
  &lt;/application&gt;
  </code></pre>
