如何知道应用程序打开通知或应用程序图标点击android？

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 检测应用程序是否是从图标启动
        if ((getIntent().getFlags() & Intent.FLAG_ACTIVITY_LAUNCHED_FROM_HISTORY) == 0) {
            // 应用程序是从图标启动的
            Log.d("AppLaunch", "Application icon clicked");
        }
    }
}

// 创建一个Intent，用于处理通知点击事件
Intent intent = new Intent(this, NotificationHandlerActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

// 构建通知
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, CHANNEL_ID)
        .setSmallIcon(R.drawable.notification_icon)
        .setContentTitle("My Notification")
        .setContentText("Click to open app")
        .setContentIntent(pendingIntent)
        .setAutoCancel(true);

// 获取NotificationManager并显示通知
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(NOTIFICATION_ID, builder.build());

public class NotificationHandlerActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_notification_handler);
    }

    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        // 处理通知点击事件
        Log.d("NotificationClick", "Notification was clicked");
    }
}
