添加 AppIndexing API

Created: November-22, 2018

对于将此添加到项目中，你可以轻松找到官方文档，但在此示例中，我将重点介绍一些需要注意的关键区域。

第 1 步： - 添加谷歌服务

dependencies {
      ...
      compile 'com.google.android.gms:play-services-appindexing:9.4.0'
      ...
    }

第 2 步： - 导入类

import com.google.android.gms.appindexing.Action;
import com.google.android.gms.appindexing.AppIndex;
import com.google.android.gms.common.api.GoogleApiClient;

第 3 步： - 添加 App Indexing API 调用

private GoogleApiClient mClient;
private Uri mUrl;
private String mTitle;
private String mDescription;

//If you know the values that to be indexed then you can initialize these variables in onCreate() 
@Override
protected void onCreate(Bundle savedInstanceState) {
mClient = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();
mUrl = "http://examplepetstore.com/dogs/standard-poodle";
mTitle = "Standard Poodle";
mDescription = "The Standard Poodle stands at least 18 inches at the withers";
}

//If your data is coming from a network request, then initialize these value in onResponse() and make checks for NPE so that your code won’t fall apart.

//setting title and description for App Indexing
mUrl = Uri.parse(“android-app://com.famelive/https/m.fame.live/vod/” +model.getId());
mTitle =   model.getTitle();
mDescription = model.getDescription();

mClient.connect();
AppIndex.AppIndexApi.start(mClient, getAction());

@Override
protected void onStop() {
if (mTitle != null && mDescription != null && mUrl != null) //if your response fails then check whether these are initialized or not
   if (getAction() != null) {
       AppIndex.AppIndexApi.end(mClient, getAction());
       mClient.disconnect();
    }
 super.onStop();
}

 public Action getAction() {
   Thing object = new Thing.Builder()
       .setName(mTitle)
       .setDescription(mDescription)
       .setUrl(mUrl)
       .build();

 return new Action.Builder(Action.TYPE_WATCH)
       .setObject(object)
       .setActionStatus(Action.STATUS_TYPE_COMPLETED)
       .build();
}
