我有两个活动第一个用于输入数字的活动来检查来自firebase的发送otp代码的auth，但我需要将代码放入第二个活动中使用Textwatcher
这里我的第一个活动代码现在可以输入数字并转到第二个活动并接收Otp代码并传递给第二个活动
@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();
}
}
}
});
}
这是我的第二个活动，我正在尝试使用Textwatcher的简单代码并获得此错误

}
答案 0 :(得分：1)
我的问题是我的google_services.json中的api_key值为空。这是因为firebase为我生成的默认json文件根本没有api_key值，所以我只是手动添加一个以使其工作。在此处添加随机字符串值将使codelab工作，但请确保停止当前运行并重建项目，否则Android Studio自动运行功能将在不更新正在使用的json文件的情况下运行。
你可以从中获取你的api密钥。 /console.firebase.google.com/project - ＆gt;你的项目 - ＆gt;设置 - ＆gt;一般。
并将其添加到google_services.json current_key
