This is my main activity..

                    && getIntent().getAction().equals(Intent.ACTION_MAIN)
            ) {
                finish();
                processIntent(getIntent());
                return;
            }
    
            SharedPreferences notificationStatus = getApplicationContext().getSharedPreferences(Constants.NotificationStatus, MODE_PRIVATE);
            SharedPreferences.Editor edit = notificationStatus.edit();
            edit.putString("status", "true");
            edit.apply();
            progressBar = findViewById(R.id.spin_kit);
            progressBarHolder = findViewById(R.id.progressBarHolder);
            mAuth = FirebaseAuth.getInstance();
            mDatabase = FirebaseDatabase.getInstance().getReference();
    
            final FirebaseUser user = mAuth.getCurrentUser();
            ActionBar actionBar = getSupportActionBar();
            actionBar.hide();
            navView = findViewById(R.id.nav_view);
            navView.setLabelVisibilityMode(LabelVisibilityMode.LABEL_VISIBILITY_LABELED);
    
            AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(
                    R.id.navigation_home, R.id.navigation_lessons, R.id.navigation_prematch, R.id.navigation_journals, R.id.navigation_move)
                    .build();

            NavigationUI.setupWithNavController(navView, navController);
    
        }
    


    @Override
    protected void onNewIntent(Intent intent) {
        super.onNewIntent(intent);
        processIntent(intent);
    }
    


private void processIntent(Intent intent) {

        if (intent != null && intent.getExtras() != null) {
            mAuth = FirebaseAuth.getInstance();
            mDatabase = FirebaseDatabase.getInstance().getReference();

            final FirebaseUser user = mAuth.getCurrentUser();
            //   checkStatus();
            Bundle bundle = new Bundle();
            id = intent.getExtras().get("id").toString();

            type = intent.getExtras().get("type").toString();
}
        }

From process intent i want to open my fragment using navcontroller but it open the mainactivity and load the home fragment instead the the playerfragment that i want to implement on click of the notification.

The player fragment is in the nav graph of the main activity.

Most of the stack overflow answers contain the navdeeplink that doesnt work here it openes the main activity and load the data of the main activity instead the destination.

Anyone how to open a fragment when user click on the notification when activity is running and when activity is in the background ?

CodePudding user response：

There is no direct way to open fragment from notifications. In the notification pending intent add putextras and get it in activity and navigate corresponding fragment

notificationIntent.putExtra("redirect", "homefragment");

In your activity

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

      String value= intent.getExtras().get("redirect").toString();
      if(value=="homefragment")
       {
              // redirect your fragment
       }

CodePudding user response：

You can do that using Explicit Deep Links in Navigation Architecture.

You can check this article to proceed with it: Navigating with Deep Links

You should also check Developer Docs. They provide in-depth description of what's going on internally
