如何解决使用Firebase验证Android Studio中的OTP时，应用崩溃
我试图在Android Studio中构建OTP系统，但是我想到了下面给出的代码，但是，每次我尝试将OTP发送到我的电话号码时，应用程序都崩溃了。这是代码：
Signp3rdClass.java
public class Signup3rdClass extends AppCompatActivity {
TextInputLayout phoneNumber;
CountryCodePicker countryCodePicker;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_signup3rd_class);
//Hooks
countryCodePicker = findViewById(R.id.country_code_picker);
phoneNumber = findViewById(R.id.signup_phone_number);
}
public void callVerifyOTPScreen(View view) {
if(!validatePhoneNumber()){
return;
}
Intent intent = new Intent(getApplicationContext(),VerifyOTP.class);
String _fullName = getIntent().getStringExtra("fullname");
String _username = getIntent().getStringExtra("username");
String _email = getIntent().getStringExtra("email");
String _password = getIntent().getStringExtra("password");
String _gender = getIntent().getStringExtra("gender");
String _date = getIntent().getStringExtra("date");
String _getUserPhoneNumber = phoneNumber.getEditText().getText().toString().trim();
String _phoneNo = "+" + countryCodePicker.getFullNumber() + _getUserPhoneNumber;
intent.putExtra("fullName",_fullName);
intent.putExtra("username",_username);
intent.putExtra("email",_email);
intent.putExtra("password",_password);
intent.putExtra("date",_date);
intent.putExtra("gender",_gender);
intent.putExtra("phoneNo",_phoneNo);
startActivity(intent);
}
private boolean validatePhoneNumber() {
String val = phoneNumber.getEditText().getText().toString().trim();
String checkNo = "[7-9][0-9]{9}";
if (val.isEmpty()) {
phoneNumber.setError("Enter valid Phone Number!");
return false;
} else if (!val.matches(checkNo)) {
phoneNumber.setError("Enter valid Phone Number!");
return false;
} else {
phoneNumber.setError(null);
phoneNumber.setErrorEnabled(false);
return true;
}
}
}

这是我的OTP验证课程：
VerifyOTP.java
public class VerifyOTP extends AppCompatActivity {
PinView pinFromUser;
String codeBySystem;
FirebaseAuth mAuth;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_verify_o_t_p);
pinFromUser = findViewById(R.id.pin_view);
String _phoneNumber = getIntent().getStringExtra("phoneNo");
mAuth = FirebaseAuth.getInstance();
sendVerificationCodeToUser(_phoneNumber);
}
private void sendVerificationCodeToUser(String phoneNumber) {
PhoneAuthOptions options =
PhoneAuthOptions.newBuilder(mAuth)
.setPhoneNumber(phoneNumber) // Phone number to verify
.setTimeout(60L,TimeUnit.SECONDS) // Timeout and unit
.setActivity(this) // Activity (for callback binding)
.setCallbacks(mCallbacks) // OnVerificationStateChangedCallbacks
.build();
PhoneAuthProvider.verifyPhoneNumber(options);
}
private PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks =
new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
@Override
public void onCodeSent(@NonNull String s,@NonNull PhoneAuthProvider.ForceResendingToken forceResendingToken) {
super.onCodeSent(s,forceResendingToken);
codeBySystem = s;
}
@Override
public void onVerificationCompleted(@NonNull PhoneAuthCredential phoneAuthCredential) {
String code = phoneAuthCredential.getSmsCode();
if(code != null){
pinFromUser.setText(code);
verifyCode(code);
}
}
@Override
public void onVerificationFailed(@NonNull FirebaseException e) {
Toast.makeText(VerifyOTP.this,e.getMessage(),Toast.LENGTH_SHORT).show();
}
};
private void verifyCode(String code) {
PhoneAuthCredential credential = PhoneAuthProvider.getCredential(codeBySystem,code);
signInWithPhoneAuthCredential(credential);
}
private void signInWithPhoneAuthCredential(PhoneAuthCredential credential) {
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this,new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
Toast.makeText(VerifyOTP.this,"Verification Completed!",Toast.LENGTH_SHORT).show();
} else {
if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) {
Toast.makeText(VerifyOTP.this,"Verification failed! Please try again",Toast.LENGTH_LONG).show();
}
}
}
});
}

请让我知道我在做什么错了。
解决方法
在build.gradle（：app）中实现“ androidx.browser：browser：1.2.0”
