Android 的 Instagram 分享到 Reels

本文件說明如何將分享功能整合至 Android 應用程式，方便用戶將圖像、影片和貼圖分享到 Instagram 的 Reels。

Overview

Reels Layers

The Reels composer has a background video layer and an optional sticker layer.

  • Background Video Layer – A video fills the screen
  • Sticker Layer – An optional sticker can appear in front of the video

Sharing Icon

For a consistent user experience across apps, download the standard sharing icon for Instagram Reels and use it in your app.

Before You Start

You will need:

  • A Meta app ID
  • You must Go Live with your Meta app before your app users can share content

Terms and Policies

By accessing and using this functionality, you acknowledge and agree to be bound by the Meta Platform Terms and Developer Policies. You also represent and warrant that any content made available through your application or website, or shared to Instagram Reels from your application or website, does not infringe upon the intellectual property rights of any third party and that you own, control or have otherwise secured all rights necessary to distribute, copy, publicly perform and display, or otherwise use the content via this functionality, including as uploaded and shared on Instagram Reels. You further represent and warrant that you have the authority to make the foregoing representations on behalf of your organization. If you do not have such authority or are otherwise unable to make the foregoing representations, you are not authorized to continue and should not do so.

實作分享到 Instagram

您可以使用 Explicit Intent（顯示意圖）啟動 Instagram 應用程式並向其傳送 Reels 內容。Instagram 應用程式將接收內容並載入到 Reels 撰寫工具，用戶即可編輯內容並發佈到自己的 Reels。

分享流程通常會執行以下操作：

  1. 實例化 Intent。
  2. 將套件設定為 "com.instagram.android"，確保 Instagram 應用程式處理 Intent。
  3. 將您的 Meta 應用程式編號和影音素材內容附加到 Intent。
  4. 實例化 Activity。
  5. 授予 URI 權限，確保 Instagram 可以讀取影音素材內容。
  6. 驗證 Activity 是否可以解析 Intent 並啟動 Activity。

請移除您在用戶裝置上建立的任何暫存檔案。

// Attach your App ID to the intent
val appId = "your-app-id"
intent.putExtra("com.instagram.platform.extra.APPLICATION_ID", appId)

// Attach your image or video to the intent from a URI
val mediaAssetUri = Uri.parse("your-image-or-video-asset-uri-goes-here")
intent.setDataAndType(mediaAssetUri, "image/* video/*")
intent.putExtra(Intent.EXTRA_STREAM, mediaAssetUri)

// Instantiate an activity
val activity: Activity = getActivity()

// Grant URI permissions
intent.flags = Intent.FLAG_GRANT_READ_URI_PERMISSION
val resInfoList = activity.packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY)
for (resolveInfo in resInfoList) {
    val packageName = resolveInfo.activityInfo.packageName
    activity.grantUriPermission(packageName, mediaAssetUri, Intent.FLAG_GRANT_READ_URI_PERMISSION)
}

// Verify that the activity resolves the intent and start it
if (activity.packageManager.resolveActivity(intent, 0) != null) {
    activity.startActivityForResult(intent, 0)
}
// Instantiate an intent
Intent intent = new Intent("com.instagram.share.ADD_TO_REEL");

// Set package
intent.setPackage("com.instagram.android");

// Attach your App ID to the intent
String appId = "your-app-id";
intent.putExtra("com.instagram.platform.extra.APPLICATION_ID", appId);

// Attach your image or video to the intent from a URI
Uri mediaAssetUri = Uri.parse("your-image-or-video-asset-uri-goes-here");
intent.setDataAndType(mediaAssetUri, "image/* video/*");
intent.putExtra(Intent.EXTRA_STREAM, mediaAssetUri);

// Instantiate an activity
Activity activity = getActivity();

// Grant URI permissions
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
List<ResolveInfo> resInfoList = activity.getPackageManager().queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
for (ResolveInfo resolveInfo : resInfoList) {
    String packageName = resolveInfo.activityInfo.packageName;
    activity.grantUriPermission(packageName, mediaAssetUri, Intent.FLAG_GRANT_READ_URI_PERMISSION);
