Setup

Share

Sharing content using Instagram Share helper is easier than anything else, but before that there are a few things that needs to be done.

• Open your main AndroidManifest.xml file in Assets/Plugins/Android/ folder and add this code inside tag:

    <provider
        android:name="androidx.core.content.FileProvider"
        android:authorities="com.package.name.fileprovider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/file_paths"/>
    </provider>
  

Where com.package.name is the package name of your application.

• Add this permission if it’s not already included in your AndroidManifest.xml file:

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
  

• Last but not least add <queries> tag inside your manifest file:

    <queries>
        <package android:name="com.instagram.android" />
    </queries>
  

Here is a sample AndroidManifest.xml file:

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.unity3d.player" android:installLocation="preferExternal" android:theme="@android:style/Theme.NoTitleBar" android:versionCode="1" android:versionName="1.0">
        <supports-screens android:smallScreens="true" android:normalScreens="true" android:largeScreens="true" android:xlargeScreens="true" android:anyDensity="true" />
        <queries>
            <package android:name="com.instagram.android" />
        </queries>
        <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
        <application android:icon="@drawable/app_icon" android:label="@string/app_name" android:debuggable="false">
            <activity android:name="com.unity3d.player.UnityPlayerActivity" android:label="@string/app_name" android:configChanges="orientation|screenSize">
                <intent-filter>
                    <action android:name="android.intent.action.MAIN" />
                    <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
                <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
                <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="true" />
            </activity>
            <provider android:name="androidx.core.content.FileProvider" android:authorities="com.hardartcore.instagramshare.fileprovider" android:exported="false" android:grantUriPermissions="true">
                <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths"/>
            </provider>
        </application>
    </manifest>

And after the setup is complete you can use the helper class as:

    public class DemoSceneScript : MonoBehaviour
    {
        // Share Image to Instagram
        public void ShareImageToInstagram()
        {
            InstagramShareHelper.ShareImageToInstagram(filePath);
        }
        public void ShareVideoToInstagram()
        {
            InstagramShareHelper.ShareVideoToInstagram(filePath);
        }
        public void ShareImageAsInstagramStory()
        {
            InstagramShareHelper.ShareImageAsInstagramStory(filePath, null);
        }
        public void ShareVideoAsInstagramStory()
        {
            InstagramShareHelper.ShareVideoAsInstagramStory(filePath, null);
        }
        public void ShareImageWithGradientAsInstagramStory()
        {
            InstagramShareHelper.ShareImageWithGradientAsInstagramStory(filePath, "#02937B", "#1B64A9", null);
        }
        public void ShareBackgroundImageAndStickerAsInstagramStory()
        {
            InstagramShareHelper.ShareBackgroundImageAndStickerAsInstagramStory(backgroundImagePath, stickerPath, null);
        }
    }

Build Errors

If you encounter an issue: unexpected element <queries> found in <manifest> There is an easy fix for that: go to File -> Build Settings -> Player Settings -> Publishing Settings and select Custom Base Gradle Template. After that open the generated file baseProjectTemplate.gradle under Assets/Plugins/Android folder and change com.android.tools.build:gradle:*** to

Unity 2019.4+ -> com.android.tools.build:gradle:3.4.3
Unity 2021.3+ -> com.android.tools.build:gradle:4.0.1
