Here are some code snippets to help you implement the collage app:

Step 1: Create the collage interface

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns_android="http://schemas.android.com/apk/res/android"

    xmlns_app="http://schemas.android.com/apk/res-auto"

    android_layout_width="match_parent"

    android_layout_height="match_parent"

    android_orientation="vertical">



    <ImageView

        android_id="@+id/imageView"

        android_layout_width="match_parent"

        android_layout_height="match_parent" />



    <TextView

        android_id="@+id/textView"

        android_layout_width="match_parent"

        android_layout_height="wrap_content"

        android_textSize="24sp" />



</LinearLayout>

Step 2: Implement the collage functionality

public class CollageActivity extends AppCompatActivity {



    private ImageView imageView;

    private TextView textView;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_collage);



        imageView = findViewById(R.id.imageView);

        textView = findViewById(R.id.textView);



        // Load the collage images

        LoadCollageImages();



        // Edit the collage images

        EditCollageImages();

    }



    private void LoadCollageImages() {

        // Load the collage images from the gallery

        Intent intent = new Intent(this, GalleryActivity.class);

        startActivity(intent);

    }



    private void EditCollageImages() {

        // Edit the collage images using the collage editor

        EditCollageImagesUsingEditor();

    }



    private void EditCollageImagesUsingEditor() {

        // Create a new collage editor

        CollageEditor editor = new CollageEditor(this);



        // Add the collage images to the editor

        editor.addImage(imageView);



        // Save the edited collage image

        editor.saveImage();

    }

}

Step 3: Create the collage editor

public class CollageEditor extends AppCompatActivity {



    private ImageView imageView;

    private TextView textView;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_collage_editor);



        imageView = findViewById(R.id.imageView);

        textView = findViewById(R.id.textView);



        // Load the collage images

        LoadCollageImages();



        // Edit the collage images

        EditCollageImages();

    }



    private void LoadCollageImages() {

        // Load the collage images from the gallery

        Intent intent = new Intent(this, GalleryActivity.class);

        startActivity(intent);

    }



    private void EditCollageImages() {

        // Create a new collage editor

        CollageEditor editor = new CollageEditor(this);



        // Add the collage images to the editor

        editor.addImage(imageView);



        // Save the edited collage image

        editor.saveImage();

    }

}

Step 4: Implement the navigation

public class CollageActivity extends AppCompatActivity {



    private Button button1;

    private Button button2;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_collage);



        button1 = findViewById(R.id.button1);

        button2 = findViewById(R.id.button2);



        // Add the navigation buttons to the layout

        button1.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                // Navigate to the collage mode 1

                Intent intent = new Intent(CollageActivity.this, CollageMode1Activity.class);

                startActivity(intent);

            }

        });



        button2.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                // Navigate to the collage mode 2

                Intent intent = new Intent(CollageActivity.this, CollageMode2Activity.class);

                startActivity(intent);

            }

        });

    }

}

Step 5: Implement the sharing

public class CollageActivity extends AppCompatActivity {



    private Button button1;

    private Button button2;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_collage);



        button1 = findViewById(R.id.button1);

        button2 = findViewById(R.id.button2);



        // Add the sharing buttons to the layout

        button1.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                // Share the collage image

                Intent intent = new Intent(Intent.ACTION_SEND);

                intent.setType("image/*");

                intent.putExtra(Intent.EXTRA_STREAM, imageView);

                intent.putExtra(Intent.EXTRA_TITLE, "Collage Image");

                intent.putExtra(Intent.EXTRA_TEXT, "This is a collage image");

                startActivity(Intent.createChooser(intent, "Choose a sharing option"));

            }

        });



        button2.setOnClickListener(new View.OnClickListener() {

            @Override
