Installing the fork</h4>
|
||
<p>First, you need to install <code>react-native</code> from your fork. For example, to install the master branch from the official repo, run the following:</p>
|
||
<pre><code class="hljs css languages- sh">npm install --save github:facebook/react-native<span class="hljs-comment">#master</span>
|
||
</code></pre>
|
||
<p>Alternatively, you can clone the repo to your <code>node_modules</code> directory and run <code>npm install</code> inside the cloned repo.</p>

|

<p>Modify your <code>android/app/build.gradle</code>, and add:</p>

|
||
<p>Building from source can take a long time, especially for the first build, as it needs to download ~200 MB of artifacts and compile the native code. Every time you update the <code>react-native</code> version from your repo, the build directory may get deleted, and all the files are re-downloaded. To avoid this, you might want to change your build directory path by editing the <code>~/.gradle/init.gradle</code> file:</p>
|
||
<pre><code class="hljs css languages- gradle">gradle.projectsLoaded {
|
||
rootProject.<span class="hljs-keyword">allprojects</span> {

buildDir = <span class="hljs-string">"/path/to/build/directory/${rootProject.name}/${project.name}"</span>

|
||
<p>If you find that you need to push up a locally compiled React Native .aar and related files to a remote Nexus repository, you can.</p>
|
||
<p>Start by following the <code>Point Gradle to your Android SDK</code> section of this page. Once you do this, assuming you have Gradle configured properly, you can then run the following command from the root of your React Native checkout to build and package all required files:</p>
|
||
<pre><code class="hljs">./gradlew <span class="hljs-string">ReactAndroid:</span>installArchives
|
||
</code></pre>
|
||
<p>This will package everything that would typically be included in the <code>android</code> directory of your <code>node_modules/react-native/</code> installation in the root directory of your React Native checkout.</p>
