Question

我正在按照youtube中的教程将数据保存到数据库Firebase中，但是当我运行项目时，我的应用程序崩溃了。有人可以帮我吗？

运行我的应用程序时，此错误显示在我的logcat中：

07-31 13:33:16.488 3825-3825/com.personalcoding.firebaserealtimedatabase E/AndroidRuntime: FATAL EXCEPTION: main

这是我的主要活动代码：

public class MainActivity extends AppCompatActivity {

    EditText    editTextName;
    Button      buttonAdd;
    Spinner spinnerGenres;

    DatabaseReference databaseArtists;

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

        databaseArtists = FirebaseDatabase.getInstance().getReference("artists");

        editTextName = (EditText)findViewById(R.id.editTextName);
        buttonAdd = (Button)findViewById(R.id.buttonAddArtist);
        spinnerGenres = (Spinner)findViewById(R.id.spinnerGenres);

        buttonAdd.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                addArtist();
            }
        });
    }

    private void addArtist(){
        String name = editTextName.getText().toString().trim();
        String genre = spinnerGenres.getSelectedItem().toString();

        //cek nama tidak boleh kosong
        if(!TextUtils.isEmpty(name)){

            String id = databaseArtists.push().getKey();
            Artist artist = new Artist(id, name, genre);
            databaseArtists.child(id).setValue(artist);

            Toast.makeText(this, "Data success added", Toast.LENGTH_LONG).show();
        }else{
            Toast.makeText(this, "You should enter a name", Toast.LENGTH_LONG).show();
        }
    }
}

致命异常：主要PID：3825
