How to use Explicit intents in an Android app?

Explicit intents allow you to start a specific activity or service in your Android app. Unlike implicit intents, which are used to invoke components from other applications, explicit intents target a specific component using its class name. This is particularly useful for launching activities within the same application.

To create an explicit intent, you typically need to create an instance of the Intent class and specify the component you want to start.

Intent explicitIntent = new Intent(CurrentActivity.this, TargetActivity.class);
startActivity(explicitIntent);

Here’s a simple example of how to implement an explicit intent to start a new activity:

public class CurrentActivity extends AppCompatActivity {
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_current);
        
        Button button = findViewById(R.id.button_start);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Create an explicit intent to start TargetActivity
                Intent explicitIntent = new Intent(CurrentActivity.this, TargetActivity.class);
                startActivity(explicitIntent);
            }
        });
    }
}
