这条线正在破坏我的firebase注册应用程序**mFirebaseAuth=FirebaseAuth.getInsta

Question

删除此行时mFirebaseAuth=FirebaseAuth.getInstance((然后activity_signup.xml在我的android工作室中运行，但当我运行带有此行的程序停止工作并崩溃。

既然没有它我就无法开发应用程序，该怎么办？

程序其他部分的一些依赖项，如位置、短信、上传图片

这是我的SignUp.java

public class SignupActivity extends AppCompatActivity {
EditText emailId, password;
Button btnSignUp;
TextView tvSignIn;
FirebaseAuth mFirebaseAuth;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_signup);
mFirebaseAuth = FirebaseAuth.getInstance();
emailId=findViewById(R.id.editText);
password=findViewById(R.id.editText2);
btnSignUp=findViewById(R.id.button);
tvSignIn=findViewById(R.id.textView);
}
}

这是我的Build.gradle(应用程序(

apply plugin: 'com.google.gms.google-services'
android {
compileSdkVersion 30
buildToolsVersion "30.0.0"
defaultConfig {
applicationId "com.example.getlocation"
minSdkVersion 24

versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {

}
}
}

implementation 'com.google.android.gms:play-services-auth:10.0.1'
}
apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

这是我在运行部分中得到的错误，其中第29行正在初始化FirebaseAuth实例

Answer 1

您使用的是这些依赖项的一个非常旧的版本：

implementation 'com.google.firebase:firebase-core:11.8.0'
implementation 'com.google.firebase:firebase-auth:11.8.0'

您应该确保所有Firebase依赖项都是文档中发行说明所述的最新版本。它们通常应该同时进行升级。
