我有兩個活動的第一個活動的輸入數量以檢查AUTH從火力發OTP代碼，但我需要把代碼中的第二個活動與Textwatcher火力地堡電話認證介紹如何OTP密碼和訪問發送到另一個活動
在這裏我第一次活動代碼現在可以把數量和去次活動並獲得OTP代碼，並傳遞給第二活動
@Override
public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
Toast.makeText(OTP1.this,"verifucation done"+ phoneAuthCredential,Toast.LENGTH_LONG).show();
}
@Override
public void onVerificationFailed(FirebaseException e) {
Toast.makeText(OTP1.this,"verifucation fail",Toast.LENGTH_LONG).show();
if (e instanceof FirebaseAuthInvalidCredentialsException) {
// Invalid request
// [START_EXCLUDE]
Toast.makeText(OTP1.this,"invalid mob no",Toast.LENGTH_LONG).show();
// [END_EXCLUDE]
} else if (e instanceof FirebaseTooManyRequestsException) {
// The SMS quota for the project has been exceeded
// [START_EXCLUDE]
Toast.makeText(OTP1.this,"quta over" ,Toast.LENGTH_LONG).show();
// [END_EXCLUDE]
}
}
@Override
public void onCodeSent(String verificationId, PhoneAuthProvider.ForceResendingToken token) {
// The SMS verification code has been sent to the provided phone number, we
// now need to ask the user to enter the code and then construct a credential
// by combining the code with a verification ID.
//Log.d(TAG, "onCodeSent:" + verificationId);
Toast.makeText(OTP1.this,"Verification code sent to mobile",Toast.LENGTH_LONG).show();
// Save verification ID and resending token so we can use them later
mVerificationId = verificationId;
mResendToken = token;
startActivity(new Intent(OTP1.this,OTP2.class));
finish();
}
};
btn_next = (ImageButton)findViewById(R.id.nextButoon);
btn_next.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
PhoneAuthProvider.getInstance().verifyPhoneNumber(
"+66"+ put_num.getText().toString(), // Phone number to verify
60, // Timeout duration
TimeUnit.SECONDS, // Unit of timeout
OTP1.this, // Activity (for callback binding)
mCallbacks); // OnVerificationStateChangedCallbacks
}
});
}
private void signInWithPhoneAuthCredential(PhoneAuthCredential credential) {
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
// Sign in success, update UI with the signed-in user's information
//Log.d(TAG, "signInWithCredential:success");
Toast.makeText(OTP1.this,"Verification done",Toast.LENGTH_LONG).show();
FirebaseUser user = task.getResult().getUser();
// ...
} else {
// Sign in failed, display a message and update the UI
//Log.w(TAG, "signInWithCredential:failure", task.getException());
if (task.getException() instanceof FirebaseAuthInvalidCredentialsException) {
// The verification code entered was invalid
Toast.makeText(OTP1.this,"Verification failed code invalid",Toast.LENGTH_LONG).show();
}
}
}
});
}
而且我試圖使用Textwatcher一個簡單的代碼，並得到這個錯誤這是我的第二個活動
