+# Upgrade gradle for Android projects
+
+To integrate react-native-camera into your own react native project and make it work for Android, you need to edit the following files in the `android` folder under your project folder:
+
+* In the `android/gradle.properties` file: 
+
+```
+android.useDeprecatedNdk=true
+android.enableAapt2=false
+```
+
+
+* In the `android/build.gradle` file:
+
+```
+uildscript {
+    repositories {
+        jcenter()
+        maven {
+            url 'https://maven.google.com'
+            name 'Google'
+        }
+    }
+    dependencies {
+        classpath 'com.android.tools.build:gradle:3.1.0'
+
+        // NOTE: Do not place your application dependencies here; they belong
+        // in the individual module build.gradle files
+    }
+}
+
+allprojects {
+    repositories {
+        mavenLocal()
+        jcenter()
+        maven {
+            url 'https://maven.google.com'
+            name 'Google'
+        }
+        maven { url "https://jitpack.io" }
+        maven {
+            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
+            url "$rootDir/../node_modules/react-native/android"
+        }
+        configurations.all {

+
+subprojects {

+        resolutionStrategy.eachDependency { details ->
+            if (details.requested.group == 'com.android.support'
+              && !details.requested.name.contains('multidex') ) {

+            }
+        }
+    }
+}
+```
+
+* In the `android/app/build.gradle` file:
+
+```
+android {
+    compileSdkVersion 26
+    buildToolsVersion "26.0.1"
+
+    defaultConfig {
+        applicationId "appName"
