我正在尝试创建登录并使用Firebase在android studio上进行注册，但是每次我单击该按钮转到我的注册页面时，该应用都会崩溃。登录屏幕可以正常运行。以下是我的注册页面的代码。
public class signup extends AppCompatActivity {
private Button accountSignUp;
private EditText createEmail;
private EditText createPassword;
private static final String TAG = "";
private FirebaseAuth mAuth;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signup);
createEmail = (EditText) findViewById(R.id.txtCreateE);
createPassword = (EditText) findViewById(R.id.txtCreateP);
accountSignUp = (Button) findViewById(R.id.btnAccountSignUp);
mAuth = FirebaseAuth.getInstance();
accountSignUp.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String email = createEmail.getText().toString();
String password = createPassword.getText().toString();
if (TextUtils.isEmpty(email)) {
Toast.makeText(getApplicationContext(),
"Enter Email", Toast.LENGTH_SHORT).show();
return;
}
if (TextUtils.isEmpty(password)) {
Toast.makeText(getApplicationContext(),
"Enter Password", Toast.LENGTH_SHORT).show();
return;
}
mAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(signup.this,
new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()){
Log.d(TAG, "createUserWithEmail:success");
FirebaseUser user = mAuth.getCurrentUser();
Intent intent = new Intent(signup.this, HomeScreen.class);
startActivity(intent);
finish();
}else{
Log.w(TAG, "createUserWithEmail:failure", task.getException());
Toast.makeText(signup.this, "Failed", Toast.LENGTH_SHORT).show();
}
}
});
}
});
}//end of onCreate
}
