最近因为项目需求，需要接入firebase dynamic links来增加推广渠道和升级用户体验，刚开始对这个深层动态链接是一脸懵逼的，完全不知道它的核心思想和用法，然后就去官方开发者文档里看了之后，终于大概理解了它的核心思想，官方文档面熟的比较详细：https://firebase.google.com/docs/dynamic-links/，我个人描述就是，跨平台，无论web、iOS或者Android都可以通过动态链接来进入到app的对应的页面（前提是已下载了app，如果没下载，一般是设置跳到应用商店）
接入步骤：
1.首先注册并登陆firebase console 控制台，然后创建动态链接

2.重点一步设置SHA-1 或者SHA-256 (控制台的设置》项目设置》指纹证书)
由于我的google console 里面设置了SHA-1，如果这里也设置SHA-1会报冲突，建议设置SHA-256

3.控制台的配置配置好后，剩下的就是代码了
注入依赖： compile 'com.google.firebase:firebase-invites:11.0.2'
manifest 里面的配置，记得这个配置在你处理回调的那个类里：
/**
* firebase dynamic links
* create and receive
*/
private void initDynamicLinks() {
// Create a deep link and display it in the UI
Uri deepLink = buildDeepLink(Uri.parse(Conf.DEEP_LINK_URL), 0, false);
// TODO: 2017/9/5 the deepLink should be share
// shareDeepLink(deepLink.toString()); // 一般是把这个深层链接分享出去
// [END_EXCLUDE]
// [START get_deep_link] // 当用户点击分享出去的深层链接会走这个回调
FirebaseDynamicLinks.getInstance()
.getDynamicLink(getIntent())
.addOnSuccessListener(this, new OnSuccessListener() {
@Override
public void onSuccess(PendingDynamicLinkData pendingDynamicLinkData) {
// Get deep link from result (may be null if no link is found)
Uri deepLink = null;
if (pendingDynamicLinkData != null) {
deepLink = pendingDynamicLinkData.getLink();
}
// Handle the deep link. For example, open the linked
// content, or apply promotional credit to the user's
// account.
// ...
// [START_EXCLUDE]
// Display deep link in the UI
if (deepLink != null) {
// TODO: 2017/9/5 获取回调后的深层链接并做对应处理（跳转或者其他）
showLog("deeplink=====" + deepLink.toString());
} else {
showLog("getDynamicLink: no link found");
}
// [END_EXCLUDE]
}
})
.addOnFailureListener(this, new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
showLog("getDynamicLink:onFailure" + e);
}
});
// [END get_deep_link]
