我正在尝试使用新的FirebaseUI 进行身份验证。我在 LogCat 中收到以下错误

我正在 onCreate 中启动身份验证请求：
FirebaseAuth auth = FirebaseAuth.getInstance();
if (auth.getCurrentUser() != null) {
// already signed in
Toast.makeText(this, "Signed in!", Toast.LENGTH_LONG).show();
} else {
startActivityForResult(
// Get an instance of AuthUI based on the default app
AuthUI.getInstance().createSignInIntentBuilder().build(),
RC_SIGN_IN);
Toast.makeText(this, "Not signed in", Toast.LENGTH_LONG).show();
}
并在 onActivityResult 中接受结果
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_SIGN_IN) {
if (resultCode == RESULT_OK) {
// user is signed in
Toast.makeText(this, "Signed in!", Toast.LENGTH_LONG).show();
} else {
// user is not signed in. Maybe just wait for the user to press
// "sign in" again, or show a message
Toast.makeText(this, "Not signed in!", Toast.LENGTH_LONG).show();
}
}
}
我认为我已经正确设置了它。我下载了我的 google-services.json 并放在我的 app/ 目录中。
这是我的项目build.gradle
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.2'
classpath 'com.google.gms:google-services:3.0.0'
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
和我的应用程序 gradle 文件
apply plugin: 'com.android.application'
android {
compileSdkVersion 23
buildToolsVersion "23.0.3"
defaultConfig {
applicationId "com.gmail.rixx.justin.cashcaddy"
minSdkVersion 16
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.google.firebase:firebase-core:9.2.0'
compile 'com.google.firebase:firebase-database:9.2.0'
compile 'com.google.firebase:firebase-auth:9.2.0'
compile 'com.google.firebase:firebase-crash:9.2.0'
compile 'com.firebaseui:firebase-ui:0.4.1'
}
apply plugin: 'com.google.gms.google-services'
当应用程序打开时，崩溃就发生了，我认为这只是我的一个配置的一些小问题。
谢谢
【问题讨论】：
-
您是否在控制台上的 Firebase 项目中启用了登录方法？
-
是的。我有一个成功使用电子邮件和密码的网络应用程序。
-
你能分享你的 app.gradle 吗？
-
我认为您在此处粘贴的崩溃日志不是您实际错误的原因，请仔细查看崩溃日志并尝试找到真正的原因。如果您在日志中发现其他内容。一定要在这里分享..!!

我从旧的 Firebase 升级时遇到了类似的问题。看看它也许可以解决你的问题：stackoverflow.com/questions/37360126/…
