android - FirebaseApiNotAvailable 异常

问题描述

当我在 genymotion 模拟器上按我的应用程序中的登录或注册按钮时，我收到错误 FirebaseApiNotAvailable 异常。但是当我在真实设备或 android studio 模拟器上运行我的应用程序时，它不会抛出任何错误。

我收到以下错误

java.lang.ClassCastException: com.google.firebase.FirebaseApiNotAvailableException cannot be cast to com.google.firebase.auth.FirebaseAuthException
    at com.example.dharmajyoti.LoginActivity$8.onComplete(LoginActivity.java:284)
    at com.google.android.gms.tasks.zzj.run(Unknown Source:4)

    at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493)
    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)

我的毕业文件是

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'
android {
   compileSdkVersion 29
    buildToolsVersion "29.0.3"
    defaultConfig {
    applicationId "com.example.dharmajyoti"
    minSdkVersion 16
    targetSdkVersion 29
    versionCode 1
    versionName "1"
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}
lintOptions {
    checkReleaseBuilds false
    abortOnError false
     }
 }

      implementation fileTree(dir: 'libs', include: ['*.jar'])
      implementation 'androidx.appcompat:appcompat:1.1.0'
      implementation 'com.google.android.material:material:1.1.0-alpha03'
      implementation 'androidx.constraintlayout:constraintlayout:1.1.3'

testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
  }

在下面的代码中我得到了错误

1.按下登录按钮时。

auth.signInWithEmailAndPassword(email,password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {
            if(task.isSuccessful())
            {....}
            else {
                       try {
                    FirebaseAuthException e = (FirebaseAuthException )task.getException();
                }
                catch(Exception ex)
                {
                    Toast.makeText(LoginActivity.this, "Login Failed: "+ex.getMessage(), Toast.LENGTH_SHORT).show();
                    pd.dismiss();
                }
             }

解决方案

模拟器不支持 Firebase 身份验证。
