從 Android 分享到 Instagram Reels

本文件介紹如何將分享功能整合至 Android 應用程式，以便用戶將圖片、影片和貼圖分享到 Instagram 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.

執行「分享到 Instagram」

您需要使用 Explicit Intent（顯性意圖）來啟動 Instagram 應用程式，並向其傳送內容以作 Reels 之用。Instagram 應用程式會接收此等內容，並在 Reels 編輯器中加以載入，以便用戶將其編輯並發佈到自己的 Reels。

分享流程一般如下：

  1. 將 intent 實例化。
  2. 將對應的套件設為 "com.instagram.android"，以確保 Instagram 應用程式會處理此 intent。
  3. 將您的 Meta 應用程式編號和媒體內容附加到 intent。
  4. 將 activity 實例化。
  5. 授予 URI 權限，以確保 Instagram 能讀取此媒體內容。
  6. 確認此 activity 可以解析 intent，然後啟動此 activity。

移除您在用戶裝置上建立的任何臨時檔案。

資料

您應在將內容分享到 Reels 時傳送下列資料。

// 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
