从 Android 分享到 Instagram Reels

本文档介绍如何将分享功能集成到您的 Android 应用中，以便用户可以将图片、视频和贴图分享到 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.

实现“分享到 Instagram”功能

您需要使用显式意图来启动 Instagram 应用，并向其发送适用于 Reels 的内容。Instagram 应用会接收此内容并在 Reels 编辑器中加载，用户便可编辑此内容并发布到他们的 Reels。

分享流程一般如下：

  1. 实例化一个意图。
  2. 将对应程序包设为 "com.instagram.android"，以确保 Instagram 应用会处理此意图。
  3. 将您的 Meta 应用编号和媒体内容附加到意图中。
  4. 实例化一个活动。
  5. 授予 URI 权限，以确保 Instagram 能读取此媒体内容。
  6. 确认此活动可以解析意图，然后启动此活动。

移除您在用户设备上创建的任何临时文件。

数据

分享到 Reels 时，您应该发送以下数据。

数据描述

单一媒体文件示例

以下代码示例将向 Instagram 发送一个文件，以供用户编辑并发布到他们的 Instagram Reels。

// Instantiate an intent
val intent = Intent("com.instagram.share.ADD_TO_REEL")

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

// 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);
}

// Verify that the activity resolves the intent and start it
if (activity.getPackageManager().resolveActivity(intent, 0) != null) {
    activity.startActivityForResult(intent, 0);
}

多个媒体文件示例

以下代码示例将向 Instagram 发送多个文件，以供用户编辑并发布到他们的 Instagram Reels。

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

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

// Attach your files to the intent
val uri1 = Uri.parse("your-first-uri-goes-here")
val uri2 = Uri.parse("your-second-uri-goes-here")
val mediaList = mutableListOf<Uri>()
mediaList.addAll(listOf(uri1, uri2))
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, ArrayList(mediaList))

// 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 (uri in mediaList) {
  for (resolveInfo in resInfoList) {
    val packageName = resolveInfo.activityInfo.packageName
    activity.grantUriPermission(packageName, uri, 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)
}
