我成功创建了一个深层链接并将其发布到 facebook，并附有所有相关元数据：
TextView.OnClickListener inviteClickListener = new View.OnClickListener() {
@Override
public void onClick(View v) {
BranchUniversalObject branchUniversalObject = new BranchUniversalObject()
// The identifier is what Branch will use to de-dupe the content across many different Universal Objects
.setCanonicalIdentifier("item/12345")
// This is where you define the open graph structure and how the object will appear on Facebook or in a deepview
.setTitle("Suits")
.setContentDescription("Great suits here")
.setContentImageUrl("http://steezo.com/wp-content/uploads/2012/12/man-in-suit.jpg")
// You use this to specify whether this content can be discovered publicly - default is public
.setContentIndexingMode(BranchUniversalObject.CONTENT_INDEX_MODE.PUBLIC)
// Here is where you can add custom keys/values to the deep link data
.addContentMetadata("picurl", "http://steezo.com/wp-content/uploads/2012/12/man-in-suit.jpg");
LinkProperties linkProperties = new LinkProperties()
.setChannel("facebook")
.setFeature("sharing")
.addControlParameter("$desktop_url", "http://www.yahoo.com")
.addControlParameter("$ios_url", "http://www.microsoft.com");
ShareSheetStyle shareSheetStyle = new ShareSheetStyle(PlaceDetailsActivity.this, "Check this out!", "This stuff is awesome: ")
.setMoreOptionStyle(getResources().getDrawable(android.R.drawable.ic_menu_search), "Show more")
.addPreferredSharingOption(SharingHelper.SHARE_WITH.FACEBOOK)
.addPreferredSharingOption(SharingHelper.SHARE_WITH.EMAIL);
branchUniversalObject.showShareSheet(PlaceDetailsActivity.this,
linkProperties,
shareSheetStyle,
new Branch.BranchLinkShareListener() {
@Override
public void onShareLinkDialogLaunched() {
}
@Override
public void onShareLinkDialogDismissed() {
}
@Override
public void onLinkShareResponse(String sharedLink, String sharedChannel, BranchError error) {
Log.e("LinkShared", "success");
}
@Override
public void onChannelSelected(String channelName) {
}
});
branchUniversalObject.generateShortUrl(PlaceDetailsActivity.this, linkProperties, new Branch.BranchLinkCreateListener() {
@Override
public void onLinkCreate(String url, BranchError error) {
if (error == null) {
Log.i("MyApp", "got my Branch link to share: " + url);
}
}
});
}
};
我没有成功做的是确保单击链接时，它会转到我的应用程序中的正确活动。我密切关注指南，但有时我发现指南有点含糊 - https://dev.branch.io/references/android_sdk/#branch-universal-object-for-deep-links-content-analytics-and -索引。
在我想调用的活动中，我把它放在清单中：
<activity
android:name=".SuitActivity"
android:label=""
android:windowSoftInputMode="adjustResize">
<meta-data android:name="io.branch.sdk.auto_link_keys_6" android:value="picurl" />
</activity>
在 SuitActivity 类中，我输入了以下内容：
@Override
protected void onResume() {
super.onResume();
if (Branch.isAutoDeepLinkLaunch(this)) {
try {
action.setPicurl(Branch.getInstance().getLatestReferringParams().getString("picurl"));
} catch (JSONException e) {
e.printStackTrace();
}
} else {
Log.e("nondeeplink","Launched by normal application flow");
}
}
这似乎是点击 Facebook 中的链接并打开我的 SuitActivity 而不是我的 MainActivity 所需要做的所有事情，但它似乎不起作用。当我单击一个分支链接时，它会打开 MainActivity。
当我在 Branch 上创建链接时，这是日志中返回的内容：

编辑：
我什至现在添加了一个 GitHub 示例供您测试：https ://github.com/Winghin2517/BranchIOTestDeepLink
它包括两个活动：
带有 FAB 的 MainActivity - 它是通过 Android Studios 创建的新应用的标准模板。如果您单击 FAB，Branch.io 将启动并要求您添加到 facebook、复制链接等。
SecondActivity - 一旦你在 facebook 上分享它并点击链接上的 facebook，SecondActivity 应该开始。目前，当您在 facebook 或您分享的任何地方单击链接时，该链接仍会打开 MainActivity。
要使此示例正常工作，请同时将您的 branch.IO 密钥替换为清单中您的配置文件中的密钥，因为目前它们只是 XXX 的：
<meta-data android:name="io.branch.sdk.BranchKey" android:value="key_live_XXX" />
<meta-data android:name="io.branch.sdk.BranchKey.test" android:value="key_test_XXX" />
谢谢！
