android - java.lang.IllegalArgumentException : Given String is empty or null when executing Firebase updatePassword() Method 异常

Question

我目前正在使用 Firebase 实时数据库处理我的项目，但是在执行它给我的方法时遇到了问题:

 E/AndroidRuntime: FATAL EXCEPTION: main

这是我的 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();
                    }

                }
            });

这是我的 getCurrentUser() 对象初始化

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

对象在 onCreate() 方法之外，因此它必须使用 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。

我遇到了同样的问题。因为:字段 "current_key":"" in google-services.json

*通过获取新的 google-services.json 解决。并确保它具有有效性“current_key”。

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