Uploading image with text using firebase database

Question

I am trying to upload an image and the image name to firebase database in android studio,but whenever i run it my app crashes.

  public class image_upload extends AppCompatActivity {

// Folder path for Firebase Storage.
    String Storage_Path = "All_Image_Uploads/";

    // Root Database Name for Firebase Database.
    String Database_Path = "All_Image_Uploads_Database";

    // Creating button.
    Button ChooseButton, UploadButton;

    // Creating EditText.
    EditText ImageName ;

    // Creating ImageView.
    ImageView SelectImage;

    // Creating URI.
    Uri FilePathUri;

    // Creating StorageReference and DatabaseReference object.
    StorageReference storageReference;
    DatabaseReference databaseReference;

    // Image request code for onActivityResult() .
    int Image_Request_Code = 7;

    ProgressDialog progressDialog ;

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

        // Assign FirebaseStorage instance to storageReference.
        storageReference = FirebaseStorage.getInstance().getReference();

        // Assign FirebaseDatabase instance with root database name.
        databaseReference = FirebaseDatabase.getInstance().getReference(Database_Path);

        //Assign ID'S to button.
        ChooseButton = (Button)findViewById(R.id.ButtonChooseImage);
        UploadButton = (Button)findViewById(R.id.ButtonUploadImage);

        // Assign ID's to EditText.
        ImageName = (EditText)findViewById(R.id.ImageNameEditText);

        // Assign ID'S to image view.
        SelectImage = (ImageView)findViewById(R.id.ShowImageView);

        // Assigning Id to ProgressDialog.
        progressDialog = new ProgressDialog(image_upload.this);

        // Adding click listener to Choose image button.
        ChooseButton.setOnClickListener(new View.OnClickListener() {

}



This is the java class




public class ImageUploadInfo {

    public String imageName;

    public String imageURL;

    public ImageUploadInfo() {

    }

    public ImageUploadInfo(String name, String url) {

        this.imageName = name;
        this.imageURL= url;
    }

    public String getImageName() {
        return imageName;
    }

    public String getImageURL() {
        return imageURL;
    }

}

It looks like some dependency problem, could you post your your app-level build.gradle file? — Panicum, Nov 21 '19 at 13:31
When i commented on the FirebaseStorage instance in the onCreate method the activity launched, So am thinking that where the problem is from — Liam, Nov 21 '19 at 13:49
you have a problem in your MainActivity class, check your menifest file, or simply make new project and copy paste your code. — ismail, Nov 21 '19 at 14:03

Welcome to StackOverflow. While this code may solve the question, [including an explanation](https://meta.stackexchange.com/q/114762) of how and why this solves the problem would really help to improve the quality of your post, and probably result in more up-votes. Remember that you are answering the question for readers in the future, not just the person asking now. Please [edit] your answer to add explanations and give an indication of what limitations and assumptions apply. — fcdt, Oct 03 '20 at 09:56
