Add YouTube Data API to Android Studio

问题:

So, I am currently messing around with android programming in my free time, and I am using android studio as my ide of choice. I am currently trying to make a very simple app using the youtube api. My issue is that I cant figure out how to actually get the api into my application. I have used file>project structure to add the stuff to my application, but that doesnt work by itself. It stops yelling at me about syntax errors but when it compiles it errors.

I researched this a bit and have found that I need to add stuff to build.gradle or settings.gradle(or both) but i havent found a definitive answer on exactly what to do. Everything I have tried thus far hasnt worked. SO if someone could either explain to me what i have to do, or link me to a place where it explains what to do that would be great

--edit--

I am so confused right now. I started a new project. I added the libs and it was still able to compile. I then added the imports and it threw errors about it. I then added these to the build.gradle and it was able to compile perfectly

compile fileTree(dir: 'libs/youtube', include: '*.jar')
compile fileTree(dir: 'libs/youtube/libs', include: '*.jar')

But when i added this code that requires the library

/** Global instance of the HTTP transport. */
private static final HttpTransport HTTP_TRANSPORT = new NetHttpTransport();

/** Global instance of the JSON factory. */
private static final JsonFactory JSON_FACTORY = new JacksonFactory();

/** Global instance of Youtube object to make all API requests. */
private static YouTube youtube;

the syntax was fine but it threw an error upon compiling it

 Gradle: Execution failed for task ':Apitest:dexDebug'.
> Failed to run command:

and that was followed by about 100 lines of of file locations

Any ideas as to what i am doing wrong?

回答1:

Just add this dependency in gradle file:

compile 'com.google.apis:google-api-services-youtube:v3-rev181-1.22.0'

and use YouTube object.

reference: https://developers.google.com/api-client-library/java/apis/youtube/v3

Step 1: Download YoutubeAndroidPlayerApi.jar from https://developers.google.com/youtube/android/player/downloads/

Step 2: Paste it in libs folder inside app folder of project

Step 3: Add following line to build.gradle in app folder of project:

compile files('libs/YouTubeAndroidPlayerApi.jar')

Step 4:Add following imports to activity which extends YouTubeBaseActivity and implements YouTubePlayer.OnInitializedListener

import com.google.android.youtube.player.YouTubeBaseActivity;
import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayerView;
import com.google.android.youtube.player.YouTubePlayer.Provider;

Step 5: Inside OnCreate method:

//Make sure you initialize youtube player

YouTubePlayerView youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);

youTubeView.initialize(YoutubeAPIKey, this);

Where YouTubeAPIKey you would get from google console after you register your project in web mode, dont select mobile domain like Android or any

Step 6: Override methods in interface implemented as:

@Override
public void onInitializationFailure(Provider arg0,
        YouTubeInitializationResult error) {
    // TODO Auto-generated method stub
    Toast.makeText(this, "Oh no!      
    "+error.toString(),Toast.LENGTH_LONG).show();

}

@Override
public void onInitializationSuccess(Provider arg0, YouTubePlayer player,
        boolean arg2) {
    // TODO Auto-generated method stub
    player.loadVideo(VIDEO_ID);
}

Where VIDEO_ID is fetched from RESTful call to Youtube API at: "https://www.googleapis.com/youtube/v3/search" with suitable parameters passed in GET like, "q,relevanceLanguage,type,key" etc.
