【中文标题】通道被不可恢复地破坏并将被处理【英文标题】:Channel is unrecoverably broken and will be disposed 【发布时间】:2019-06-20 00:59:26 【问题描述】:我正在创建一个客户注册页面,它将客户添加到我的 firebase 数据库中。注册后,应用程序应进入下一个活动,即谷歌地图。客户被添加到数据库中,但在移动到下一个活动时崩溃。这是我的代码:
SignupActivityCustomer.java:
import android.content.Intent;
import android.support.annotation.NonNull;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.util.Patterns;
import android.view.View;
import android.widget.EditText;
import android.widget.ProgressBar;
import android.widget.Toast;
import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.firebase.auth.AuthResult;
import com.google.firebase.auth.FirebaseAuth;
import com.google.firebase.database.FirebaseDatabase;
public class SignupActivityCustomer extends AppCompatActivity implements View.OnClickListener
private EditText editTextName, editTextEmail, editTextPassword, editTextPhone;
private ProgressBar progressBar;
private FirebaseAuth mAuth;
private static final String TAG = "SignupActivityCustomer";
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signup_customer);
editTextName = findViewById(R.id.edit_text_name);
editTextEmail = findViewById(R.id.edit_text_email);
editTextPassword = findViewById(R.id.edit_text_password);
editTextPhone = findViewById(R.id.edit_text_phone);
progressBar = findViewById(R.id.progressbar);
progressBar.setVisibility(View.GONE);
mAuth = FirebaseAuth.getInstance();
findViewById(R.id.button_register).setOnClickListener(this);
@Override
protected void onStart()
super.onStart();
if (mAuth.getCurrentUser() != null)
//handle the already login user
private void registerUser()
final String name = editTextName.getText().toString().trim();
final String email = editTextEmail.getText().toString().trim();
String password = editTextPassword.getText().toString().trim();
final String phone = editTextPhone.getText().toString().trim();
if (name.isEmpty())
editTextName.setError(getString(R.string.input_error_name));
editTextName.requestFocus();
return;
if (email.isEmpty())
editTextEmail.setError(getString(R.string.input_error_email));
editTextEmail.requestFocus();
return;
if (!Patterns.EMAIL_ADDRESS.matcher(email).matches())
editTextEmail.setError(getString(R.string.input_error_email_invalid));
editTextEmail.requestFocus();
return;
if (password.isEmpty())
editTextPassword.setError(getString(R.string.input_error_password));
editTextPassword.requestFocus();
return;
if (password.length() < 6)
editTextPassword.setError(getString(R.string.input_error_password_length));
editTextPassword.requestFocus();
return;
if (phone.isEmpty())
editTextPhone.setError(getString(R.string.input_error_phone));
editTextPhone.requestFocus();
return;
if (phone.length() != 10)
editTextPhone.setError(getString(R.string.input_error_phone_invalid));
editTextPhone.requestFocus();
return;
progressBar.setVisibility(View.VISIBLE);
mAuth.createUserWithEmailAndPassword(email, password)
.addOnCompleteListener(new OnCompleteListener<AuthResult>()
@Override
public void onComplete(@NonNull Task<AuthResult> task)
Log.d(TAG, "adding customer");
if (task.isSuccessful())
Customer user = new Customer(
name,
email,
phone
);
FirebaseDatabase.getInstance().getReference("Customers")
.child(FirebaseAuth.getInstance().getCurrentUser().getUid())
.setValue(user).addOnCompleteListener(new OnCompleteListener<Void>()
@Override
public void onComplete(@NonNull Task<Void> task)
progressBar.setVisibility(View.GONE);
Log.d(TAG, "customer added");
if (task.isSuccessful())
startActivity(new Intent(SignupActivityCustomer.this, CustomerHome.class));
else
//display a failure message
);
else
Toast.makeText(SignupActivityCustomer.this, task.getException().getMessage(), Toast.LENGTH_LONG).show();
);
@Override
public void onClick(View v)
switch (v.getId())
case R.id.button_register:
registerUser();
break;
Logcat error:

【问题讨论】:
【参考方案1】:据我所知,Firebase 现在是异步工作的,因此它正在另一个线程上工作。
您可以尝试将startActivity
放入runOnUiThread(Runnable)
代码中
if (task.isSuccessful())
runOnUiThread(new Runnable()
public void run()
startActivity(new Intent(SignupActivityCustomer.this, CustomerHome.class));
);
else
//display a failure message
希望它有效
