How to integrate Search Kit? - Huawei Developers

Article Introduction
In this article we will work in integrate search and will explore many features together in this service.
Search Kit
HUAWEI Search Kit fully opens Petal Search capabilities through the device-side SDK and cloud-side APIs, enabling ecosystem partners to quickly provide the optimal mobile app search experience.
Dependencies that needed
Code:
//design
implementation 'com.google.android.material:material:1.2.1'
implementation 'androidx.recyclerview:recyclerview:1.1.0'
implementation 'com.github.bumptech.glide:glide:4.10.0'
//rxJava
implementation 'io.reactivex.rxjava2:rxjava:2.2.19'
implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'
implementation 'com.squareup.retrofit2:retrofit:2.5.0'
implementation 'com.squareup.retrofit2:converter-gson:2.5.0'
implementation 'com.squareup.retrofit2:adapter-rxjava2:2.5.0'
//searchKit HMS
implementation 'com.huawei.hms:searchkit:5.0.4.303'
1. Create a class that extends from Application
Code:
import android.app.Application
import com.huawei.hms.searchkit.SearchKitInstance
class SearchKitApplication: Application() {
override fun onCreate() {
super.onCreate()
// Initialize Search Kit.
SearchKitInstance.init(this, "your_app_id");
}
}
In Manifest in Application tag apply this below line of code
Code:
android:name=".SearchKitApplication"
3. Now we can create an empty activity with this name
SearchActivity. please take a look on important part in references.
or as you like you can modify it, if you would like.
4. In Utils package that we created in point 2, let’s create AnimationUtils class
Code:
public class AnimationUtils {
public static void expand(final View v) {
int matchParentMeasureSpec =
View.MeasureSpec.makeMeasureSpec(((View) v.getParent()).getWidth(), View.MeasureSpec.EXACTLY);
int wrapContentMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
v.measure(matchParentMeasureSpec, wrapContentMeasureSpec);
final int targetHeight = v.getMeasuredHeight();
v.getLayoutParams().height = 1;
v.setVisibility(View.VISIBLE);
Animation a =
new Animation() {
@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
v.getLayoutParams().height =
interpolatedTime == 1
? ViewGroup.LayoutParams.WRAP_CONTENT
: (int) (targetHeight * interpolatedTime);
v.requestLayout();
}
@Override
public boolean willChangeBounds() {
return true;
}
};
a.setDuration((int) (targetHeight / v.getContext().getResources().getDisplayMetrics().density));
v.startAnimation(a);
}
public static void collapse(final View v) {
final int initialHeight = v.getMeasuredHeight();
Animation a =
new Animation() {
@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
if (interpolatedTime == 1) {
v.setVisibility(View.GONE);
} else {
v.getLayoutParams().height = initialHeight - (int) (initialHeight * interpolatedTime);
v.requestLayout();
}
}
@Override
public boolean willChangeBounds() {
return true;
}
};
a.setDuration((int) (initialHeight / v.getContext().getResources().getDisplayMetrics().density));
v.startAnimation(a);
}
}
5. Now in network package let’s work on it to can get access token that will let us able to use search kit features
Code:
public class UrlHelper {
/**
* The Content REQUEST_TOKEN.
*/
public static final String REQUEST_TOKEN = "oauth2/v3/token";
// public static final String REQUEST_TOKEN = "oauth2/v2/token/https://logintestlf.hwcloudtest.cn/";
}
Code:
public interface QueryService {
@FormUrlEncoded
@POST(UrlHelper.REQUEST_TOKEN)
Observable<TokenResponse> getRequestToken(
@Field("grant_type") String grantType,
@Field("client_id") String ClientId,
@Field("client_secret") String clientSecret);
}
Code:
public class NetworkManager {
private static final String TAG = NetworkManager.class.getSimpleName();
private static NetworkManager networkManager;
public static NetworkManager getInstance() {
if (networkManager == null) {
syncInit();
}
return networkManager;
}
private static synchronized void syncInit() {
if (networkManager == null) {
networkManager = new NetworkManager();
}
}
public QueryService createService(Context context, String baseUrl) {
QueryService queryService = null;
Retrofit retrofit = null;
Retrofit.Builder builder = new Retrofit.Builder().baseUrl(baseUrl);
OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();
try {
SSLSocketFactory ssf = SecureSSLSocketFactory.getInstance(context);
X509TrustManager xtm = new SecureX509TrustManager(context);
clientBuilder.sslSocketFactory(ssf, xtm);
clientBuilder.hostnameVerifier(new StrictHostnameVerifier());
} catch (IOException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (IllegalAccessException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (NoSuchAlgorithmException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (KeyManagementException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (KeyStoreException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (CertificateException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (Exception e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
}
OkHttpClient client =
clientBuilder
.retryOnConnectionFailure(true)
.readTimeout(5000, TimeUnit.MILLISECONDS)
.connectTimeout(5000, TimeUnit.MILLISECONDS)
.build();
try {
retrofit =
builder.client(client)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
queryService = retrofit.create(QueryService.class);
} catch (Exception e) {
Log.e(TAG, "createRestClient error: " + e.getMessage());
}
return queryService;
}
}
6. In bean package, let’s start with create ListBean class
Code:
public class ListBean {
String title;
String url;
String click_url;
public String getClick_url() {
return click_url;
}
public void setClick_url(String click_url) {
this.click_url = click_url;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
}
Now we will work on create TokenResponse class:
Code:
public class TokenResponse {
String access_token;
Integer expires_in;
String token_type;
public String getAccess_token() {
return access_token;
}
public void setAccess_token(String access_token) {
this.access_token = access_token;
}
public Integer getExpires_in() {
return expires_in;
}
public void setExpires_in(Integer expires_in) {
this.expires_in = expires_in;
}
public String getToken_type() {
return token_type;
}
public void setToken_type(String token_type) {
this.token_type = token_type;
}
}

Hi i was following your sample, How can I obtain app id?
SearchKitInstance.init(this, "your_app_id");
Please help me
