小编Tre*_*ebe的帖子

我有一个使用firebase和firebase auth ui库的项目.问题是我无法使用Google登录登录,当我尝试加载一两秒钟然后只显示一个Toast消息"Developer Error".我可以用电子邮件和密码登录就好了.这只是签名apks的一个问题,当我调试Google时,登录工作正常.

在我的proguard-rules.pro中,我将minifyEnabled设置为false.

我已将SHA-1添加到我的firebase项目并已下载正确的json文件.

来自app level build.gradle的依赖块

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
})
    compile 'com.android.support:appcompat-v7:26.0.2'
    compile 'com.android.support:design:26.0.2'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:design:26.0.2'
    compile 'com.android.support:cardview-v7:26.0.2'
    compile 'com.google.firebase:firebase-database:11.4.2'
    compile 'com.google.firebase:firebase-auth:11.4.2'
    compile 'com.firebaseui:firebase-ui-auth:3.1.0'
    testCompile 'junit:junit:4.12'
}
apply plugin: 'com.google.gms.google-services'

这是我的AuthStateListener

mAuthStateListener = new FirebaseAuth.AuthStateListener() {
            @Override
            public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
                FirebaseUser user = firebaseAuth.getCurrentUser();
                if (user != null) {
                    signedInInitialized();
                } else {
                    signedOutCleanUp();
                    startActivityForResult(
                            AuthUI.getInstance()
                                    .createSignInIntentBuilder()
                                    .setTheme(R.style.FirebaseSignInTheme)
                                    .setIsSmartLockEnabled(false)
                                    .setAvailableProviders(
                                            Arrays.asList(new …
