How to use the Java library in Android to implement a custom tab (CUSTOM TABS) framework

Custom Tabs is a method that embeds the browser experience in Android applications.This article will introduce how to use the Java library to implement the custom tab framework, and provide the necessary programming code and related configuration description. 1. Introduce dependency library First, you need to add the following dependencies to the project's Build.gradle file: groovy dependencies { implementation 'androidx.browser:browser:1.3.0' } This will enable you to use the class and methods in the AndroidX browse library. 2. Create a custom tab service class Next, you need to create a class inherited from the CustomTabsserviceConnection to connect and communicate with the custom tab service.In this class, you need to implement the following methods: public class MyCustomTabsService extends CustomTabsServiceConnection { private CustomTabsClient mClient; @Override public void onCustomTabsServiceConnected(ComponentName componentName, CustomTabsClient customTabsClient) { mClient = customTabsClient; } @Override public void onServiceDisconnected(ComponentName componentName) { mClient = null; } public void launchCustomTab(Activity activity, String url) { if (mClient != null) { CustomTabsIntent.Builder builder = new CustomTabsIntent.Builder(); // Configure the appearance and behavior of the custom tab page // builder.setToolbarColor(Color.RED); // builder.setShowTitle(true); CustomTabsIntent customTabsIntent = builder.build(); customTabsIntent.launchUrl(activity, Uri.parse(url)); } } } Here we create a subclass MyCustomTabsService of CustomTabsServiceConnection, and implements OnCustomTabsserViceConnect and onServiceDisconnected methods.It also provides a LaunchCustomtab method to launch a custom tab. 3. Start the custom tab page In your application's Activity class, you can call the LaunchCustomtab method of MyCustomTabsservice to start a custom tab.For example: public class MainActivity extends AppCompatActivity { private MyCustomTabsService mCustomTabsService; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mCustomTabsService = new MyCustomTabsService(); // Connect the custom tab service CustomTabsClient.bindCustomTabsService(this, "com.android.chrome", mCustomTabsService); } @Override protected void onDestroy() { super.onDestroy(); // Connect to disconnect and custom tab service unbindService(mCustomTabsService); } public void openCustomTab(View view) { String url = "https://www.example.com"; // Start the custom tab page mCustomTabsService.launchCustomTab(MainActivity.this, url); } } In this example, we bind the custom tab service in the oncreate method of the Activity and unbundify it in the ONDESTROY method.By calling the OpenCUSTOSTAB method, you can start the custom tabs when the user clicks a button. Please note that you need to modify the "com.android.chrome" to the package name of the custom tab service you want to connect. 4. Configure AndroidManifest.xml Finally, add the next authority and service statement to the AndroidManifest.xml file of the project: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.myapp"> <uses-permission android:name="android.permission.INTERNET" /> <application ... <service android:name=".MyCustomTabsService" android:exported="true"> <intent-filter> <action android:name="android.support.customtabs.action.CustomTabsService" /> </intent-filter> </service> </application> </manifest> This will allow your application to communicate with the custom tab service. At this point, you have successfully achieved a custom tab framework and can be used in Android applications.You can configure the appearance and behavior of the custom tab page as needed to provide a better user experience.
