我正在使用Firebase将google登录集成到我的android项目中。遵循this教程之后，我能够获得登录名。但是当我选择帐户时，应用程序崩溃了。
通过我使用Kotlin语言的方式。
代码段如下：
class SignupActivity:AppCompatActivity(){
lateinit var googleSignInClient: GoogleSignInClient
lateinit var gso: GoogleSignInOptions
val RC_SIGN_IN :Int =1
lateinit var signOut:Button
lateinit var mAuth: FirebaseAuth
private var callbackManager: CallbackManager?=null
@RequiresApi(Build.VERSION_CODES.JELLY_BEAN_MR1)
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.signup)
header_signup_button.setOnClickListener {
startActivity(Intent(this,SplashscreenActivity::class.java))
}
gso = GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build()
googleSignInClient = GoogleSignIn.getClient(this,gso)
mAuth = FirebaseAuth.getInstance()
signOut = findViewById<View>(R.id.signOutBtn) as Button
signOut.visibility= View.INVISIBLE
google_signup.setOnClickListener {
view:View?->signInGoogle()
}
signupemail_button.setOnClickListener {
startActivity(Intent(this,EmailSignupActivity::class.java))
}
val fblogin_button= findViewById<Button>(R.id.facebook_signup)
fblogin_button.setOnClickListener {
callbackManager = CallbackManager.Factory.create()
LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("email"))
if (!isloggedIn()) {
LoginManager.getInstance().registerCallback(callbackManager,
object : FacebookCallback<LoginResult> {
override fun onSuccess(loginResult: LoginResult) {
Log.d("LoginActivity", "Facebook token" + loginResult.accessToken.token)
startActivity(Intent(baseContext, MainActivity::class.java))
}
override fun onCancel() {
Log.d("LoginActivity", "Facebook oncancel")
}
override fun onError(error: FacebookException?) {
Log.d("LoginActivity", "Facebook onError")
}
})
} else {
LoginManager.getInstance().unregisterCallback(callbackManager, object : FacebookCallback<LoginResult> {
override fun onSuccess(result: LoginResult?) {
GraphRequest(AccessToken.getCurrentAccessToken(), "/{user-id}/permissions/", null, HttpMethod.DELETE, GraphRequest.Callback() {
AccessToken.setCurrentAccessToken(null)
LoginManager.getInstance().logOut()
}).executeAsync()
Log.d("LoginActivity", "Facebook token" + result?.accessToken?.token)
}
override fun onCancel() {
Log.d("LoginActivityunregister", "Facebook oncancel")
}
override fun onError(error: FacebookException?) {
Log.d("LoginActivityunregister", "Facebook onError")
}
})
}
}
}
private fun signInGoogle() {
val signIntent:Intent =googleSignInClient.signInIntent
startActivityForResult(signIntent,RC_SIGN_IN)
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == RC_SIGN_IN) {
if (resultCode!= Activity.RESULT_OK) {
val task: Task<GoogleSignInAccount> = GoogleSignIn.getSignedInAccountFromIntent(data)
try {
val account = task.getResult()
val credential = GoogleAuthProvider.getCredential(account.idToken,null)
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, OnCompleteListener<AuthResult>(){
if (task.isSuccessful) {
val user = mAuth.currentUser
if (user != null) {
updateUI(user)
}
}else{
updateUI(null)
}
})
}catch (e:ApiException){
Toast.makeText(this,e.toString(),Toast.LENGTH_SHORT).show()
}
}
}
else {
callbackManager?.onActivityResult(requestCode, resultCode, data)
}
}
private fun updateUI(user: FirebaseUser?) {
val disptext = findViewById<View>(R.id.disptxt) as TextView
if (user != null) {
disptext.text = user.displayName
}
signOut.visibility=View.VISIBLE
signOut.setOnClickListener { view:View->
googleSignInClient.signOut().addOnCompleteListener {
task -> disptext.text = " "
signOut.visibility= View.INVISIBLE
}
}
}
@SuppressLint("NewApi")
override fun onBackPressed() {
super.onBackPressed()
startActivity(Intent(this,SplashscreenActivity::class.java))
}
}
private fun Any.unregisterCallback(callbackManager: CallbackManager?, facebookCallback: FacebookCallback<LoginResult>) {
}
fun isloggedIn(): Boolean {
val accessToken = AccessToken.getCurrentAccessToken()
return accessToken != null
}
清单文件：在清单文件中，我添加了元数据。

出现的错误是Caused by: com.google.android.gms.tasks.RuntimeExecutionException: com.google.android.gms.common.api.ApiException: 10。我已经看过这个issue，但没有答案可以解决我的问题。
我还将发布错误日志，以更加清楚。

此外，您还会注意到我的项目也具有Facebook登录集成。但是现在添加Google登录后，它也无法正常工作。因此，我希望能有所帮助。任何帮助表示赞赏。
答案 0 :(得分：1)
您的AndroidManifest.XML在我看来是正确的。我遇到了相同的错误：
Caused by: com.google.android.gms.tasks.RuntimeExecutionException: com.google.android.gms.common.api.ApiException: 10
这基本上意味着您要提供未知的服务器客户端ID。
在Google Developer Console中，选择您生成的项目：OAuth client ID-> Web应用程序，然后在您的Android应用程序中使用此Web应用程序客户端ID。
编辑：
我绝对知道问题出在添加到Firebase控制台的SHA1键中。因此，您可以重新生成它，然后再次将其正确放置在同一项目中。还请确保：
1）您实际签名的Android apk具有与项目的Firebase控制台中指定的指纹相同的SHA1指纹。请参阅“ Android集成”部分，该页面可在其中下载google-services.json。
2）您的Firebase项目已与Google Play链接。为此，转到页面Project Overview，然后转到Project Settings（齿轮图标），然后转到Integration tab。在该标签上，将Google Play链接到您的项目。
最后一个应该可以解决您的问题。
