java.lang.IllegalArgumentException：在执行Firebase时给定字符串为空或为空updatePassword（）方法

我目前正在使用Firebase实时数据库处理我的项目，但在执行方法时遇到问题给我：java.lang.IllegalArgumentException：在执行Firebase时给定字符串为空或为空updatePassword（）方法

E/AndroidRuntime: FATAL EXCEPTION: main 
              Process: naufal.com.tugasakhir, PID: 7291

               at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1199)

这是我updatePassword（）方法

mUser.updatePassword(repass).addOnCompleteListener(ChangePass.this, new OnCompleteListener<Void>() { 
       @Override 
       public void onComplete(@NonNull Task<Void> task) { 
        if (!task.isSuccessful()) { 
         Toast.makeText(ChangePass.this, "Update Password Failed", 
           Toast.LENGTH_SHORT).show(); 
        } else { 
         startActivity(new Intent(ChangePass.this, MainActivity.class)); 
         finish(); 
        } 

       } 
      });

，这是我getCurrentUser（）对象初始化

 final FirebaseUser mUser = FirebaseAuth.getInstance().getCurrentUser();

该对象是onCreate（）方法outisde，所以它必须使用final。

package naufal.com.tugasakhir; 

import android.content.Intent; 
import android.nfc.Tag; 
import android.support.annotation.NonNull; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.View; 
import android.widget.Button; 
import android.widget.EditText; 
import android.widget.Toast; 

import com.firebase.client.Firebase; 
import com.google.android.gms.tasks.OnCompleteListener; 
import com.google.android.gms.tasks.Task; 
import com.google.firebase.auth.FirebaseAuth; 
import com.google.firebase.auth.FirebaseUser; 

public class ChangePass extends AppCompatActivity { 

    private EditText mChangepass,mReChangePass; 
    private Button mChangeBtn; 
    private static final String TAG = ChangePass.class.getSimpleName(); 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_change_pass); 

     mChangepass = (EditText) findViewById(R.id.changePass); 
     mReChangePass = (EditText) findViewById(R.id.reChangePass); 
     mChangeBtn = (Button) findViewById(R.id.changeBtn); 

     final FirebaseUser mUser = FirebaseAuth.getInstance().getCurrentUser(); 

     mChangeBtn.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 

       String pass = mChangepass.getText().toString().trim(); 
       String repass = mReChangePass.getText().toString().trim(); 

       if(pass.isEmpty()){ 
        Toast.makeText(getApplicationContext(), "Enter New Password", Toast.LENGTH_SHORT).show(); 
       } 
       if(repass.isEmpty()){ 
        Toast.makeText(getApplicationContext(), "Enter New Password", Toast.LENGTH_SHORT).show(); 
       } 

       if(pass.length()<6){ 
        Toast.makeText(getApplicationContext(), "Password is too Short (Minimum 6)", Toast.LENGTH_SHORT).show(); 
       } 
       if(!pass.equals(repass)){ 
        Toast.makeText(getApplicationContext(), "Password Does Not Match", Toast.LENGTH_SHORT).show(); 
       } 

       assert mUser != null; 
       mUser.updatePassword(repass).addOnCompleteListener(ChangePass.this, new OnCompleteListener<Void>() { 
        @Override 
        public void onComplete(@NonNull Task<Void> task) { 
         if (!task.isSuccessful()) { 
          Toast.makeText(ChangePass.this, "Update Password Failed", 
            Toast.LENGTH_SHORT).show(); 
         } else { 
          startActivity(new Intent(ChangePass.this, MainActivity.class)); 
          finish(); 
         } 

        } 
       }); 

     }); 


    } 
}

非常感谢您的回复。

我得到了同样的问题。因为：场"current_key":""在谷歌，services.json

*通过解决获得新的谷歌，services.json。并确保它具有“current_key”的有效性。

"api_key": [ 
     { 
      "current_key": "validity-key-xxxxxxxxxxxxxxx" 
     } 
    ]
