我一直在尝试使用Firebase Auth执行电话身份验证方法，我已确保遵循所有步骤，添加我的软件包名称，使用添加SHA密钥
密钥工具-列表-v-密钥库" %用户配置文件%. android\调试.密钥库"-别名android调试密钥-storepass android-keypass android
然后添加所有依赖项，并将json文件包含到我的项目中
现在我以**+ CountryCodeXXXXX格式发送我的电话号码，由于某种原因，它在PhoneAuthProvider.OnVerificationStateChangedCallbacks()方法中给我一个MISSING_CLIENT_IDENTIFIER**，任何输入都将是有用的
这是我的密码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    editText = (EditText) findViewById(R.id.edit);
    send = (Button) findViewById(R.id.btnSend);
    send.setOnClickListener(this);
    mCallbacks= new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
        @Override
        public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {
            Toast.makeText(getBaseContext(),"Verification Successfull",Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onVerificationFailed(FirebaseException e) {
            Toast.makeText(getBaseContext(),"Verification Failed "+e,Toast.LENGTH_LONG).show();
        }
    };
}



@Override
public void onClick(View view) {
    switch (view.getId()) {

        case R.id.btnSend:
            String temp = editText.getText().toString();
            Toast.makeText(getBaseContext(),temp,Toast.LENGTH_SHORT).show();
            PhoneAuthProvider.getInstance().verifyPhoneNumber(
                    temp,        // Phone number to verify
                    60,                 // Timeout duration
                    TimeUnit.SECONDS,   // Unit of timeout
                    this,               // Activity (for callback binding)
                    mCallbacks);
    break;



    }
