This makes it easier to share APKs that run on almost all Android devices. However, this has the downside that there will be some unused native code on any device, leading to unnecessarily bigger APKs.</p> 47<p>You can create an APK for each CPU by adding the following line in your <code>android/app/build.gradle</code> file:</p> 48<div class="language-diff codeBlockContainer_mQmQ theme-code-block" style=--prism-color:#FFFFFF;--prism-background-color:#282C34><div class=codeBlockTitle_kY6l>diff</div><div class=codeBlockContent_t_Hd><pre tabindex=0 class="prism-code language-diff codeBlock_RMoD thin-scrollbar" style=color:#FFFFFF;background-color:#282C34><code class=codeBlockLines_AclH><span class=token-line style=color:#FFFFFF><span class="token plain">android {</span><br></span><span class=token-line style=color:#FFFFFF><span class="token plain" style=display:inline-block></span><br></span><span class=token-line style=color:#FFFFFF><span class="token plain"></span><span class="token unchanged prefix unchanged"> </span><span class="token unchanged line"> splits {</span><br></span><span class=token-line style=color:#FFFFFF><span class="token unchanged line"></span><span class="token unchanged prefix unchanged"> </span><span class="token unchanged line"> abi {</span><br></span><span class=token-line style=color:#FFFFFF><span class="token unchanged line"></span><span class="token unchanged prefix unchanged"> </span><span class="token unchanged line"> reset()</span><br></span><span class=token-line style=color:#FFFFFF><span class="token unchanged line"></span><span class="token unchanged prefix unchanged"> </span><span class="token unchanged line"> enable true</span><br></span><span class=token-line style=color:#FFFFFF><span class="token unchanged line"></span><span class="token unchanged prefix unchanged"> </span><span class="token unchanged line"> universalApk false</span><br></span><span class=token-line style=color:#FFFFFF><span class="token unchanged line"></span><span class="token unchanged prefix unchanged"> </span><span class="token unchanged line"> include "armeabi-v7a", "arm64-v8a", "x86", "x86_64"</span><br></span><span class=token-line style=color:#FFFFFF><span class="token unchanged line"></span><span class="token unchanged prefix unchanged"> </span><span class="token unchanged line"> }</span><br></span><span class=token-line style=color:#FFFFFF><span class="token unchanged line"></span><span class="token unchanged prefix unchanged"> </span><span class="token unchanged line"> }</span><br></span><span class=token-line style=color:#FFFFFF><span class="token unchanged line"></span><span class="token plain"></span><br></span><span class=token-line style=color:#FFFFFF><span class="token plain">}</span><br></span></code></pre></div></div> 49<p>Upload these files to markets which support device targeting, such as <a href=https://developer.amazon.com/docs/app-submission/device-filtering-and-compatibility.html target=_blank rel="noopener noreferrer">Amazon AppStore</a> or <a href=https://f-droid.org/en/ target=_blank rel="noopener noreferrer">F-Droid</a>, and the users will automatically get the appropriate APK.

We recommend you enable that in order to take advantage from things like automatic app splitting. In order to migrate from the old way of signing you need to start by <a href=#generating-an-upload-key>generating new upload key</a> and then replacing release signing config in <code>android/app/build.gradle</code> to use the upload key instead of the release one (see section about <a href=#adding-signing-config-to-your-apps-gradle-config>adding signing config to gradle</a>). Once that's done you should follow the <a href=https://support.google.com/googleplay/android-developer/answer/7384423 target=_blank rel="noopener noreferrer">instructions from Google Play Help
