使用 Firebase 在应用程序（Android Studio）中上传个人资料图片

Question

我正在尝试制作一个功能，用户必须在注册时上传他们的个人资料图片。 但我的应用程序不断停止，既不上传详细信息，也不上传个人资料图片。 但如果我删除上传图片的代码，它工作正常。 所以图片上传有问题。 请帮我解决它-

public class SelectRegistrationActivity extends AppCompatActivity {

private TextView back;
private TextView fullName,email,phone,password,regButton,gender,age;
String flag="False";
private CircleImageView dp;
//private Uri result;
private Uri filePath;

// request code
private final int PICK_IMAGE_REQUEST = 22;
FirebaseAuth mAuth;
DatabaseReference userDatabaseRef;
ProgressDialog loader;
FirebaseDatabase database= FirebaseDatabase.getInstance();
String currentUserId;
FirebaseStorage storage;
StorageReference storageReference;

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

    back = findViewById(R.id.back);//inside bracket is id given to sign in button in activity_select_registration.xml
    //the other back are just variable names

    fullName = findViewById(R.id.fullName);
    email = findViewById(R.id.email);
    phone = findViewById(R.id.phone);

在 storageReference.child 之前使用 New 关键字并运行代码。
