为空:

firebaseAuth.signInWithCredential(credential)

您需要覆盖活动中的onActivityResult
方法。添加此代码:
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
if (result.isSuccess()) {
GoogleSignInAccount account = result.getSignInAccount();
firebaseAuthWithGoogle(account);
}
}
您的handleSignInResult
方法应该是这样的:
private void handleSignInResult(GoogleSignInResult result) {
if (result.isSuccess()) {
GoogleSignInAccount googleSignInAccount = result.getSignInAccount();
if (googleSignInAccount != null) {
String userId = googleSignInAccount.getId();
}
updateUI(true);
} else {
updateUI(false);
}
}
private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
System.out.println("firebaseAuthWithGoogle:" + acct.getId());
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
auth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
System.out.println("signInWithCredential:onComplete:" + task.isSuccessful());
if (!task.isSuccessful()) {
System.out.println("signInWithCredential" + task.getException());
Toast.makeText(MainActivity.this, "Authentication failed.",Toast.LENGTH_SHORT).show();
}
}
});
}
您还需要在您的Firebase
帐户中,在Authentication
->登录方法中启用提供商
->。您需要启用您正在使用的,电子邮件/密码
,谷歌
等等
您还需要将compile'com.google.firebase:firebase auth:10.2.0'
放入build.gradle
文件中
在AndroidManifest中,您必须设置这两个权限:”和“
您还需要设置SHA1。你可以看看怎么做。最后,别忘了再次将您的google-services.json放在正确的位置
这就是firebaseAuthWithGoogle
方法的外观:
private void handleSignInResult(GoogleSignInResult result) {
if (result.isSuccess()) {
GoogleSignInAccount googleSignInAccount = result.getSignInAccount();
if (googleSignInAccount != null) {
String userId = googleSignInAccount.getId();
}
updateUI(true);
} else {
updateUI(false);
}
}
private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
System.out.println("firebaseAuthWithGoogle:" + acct.getId());
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
auth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
System.out.println("signInWithCredential:onComplete:" + task.isSuccessful());
if (!task.isSuccessful()) {
System.out.println("signInWithCredential" + task.getException());
Toast.makeText(MainActivity.this, "Authentication failed.",Toast.LENGTH_SHORT).show();
}
}
});
}
希望有帮助 再次确认我的更新代码:
private void signInGoogle(){
Intent intent = Auth.GoogleSignInApi.getSignInIntent(googleSignInApi);
startActivityForResult(intent, REQ_CODE);
}
...
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
if (requestCode == REQ_CODE){
GoogleSignInAccount account = result.getSignInAccount();
handleResult(result);
}
}
...
private void handleResult(GoogleSignInResult result){
if (result.isSuccess()){
// Google Sign In was successful, authenticate with Firebase
GoogleSignInAccount account = result.getSignInAccount();
String name = account.getDisplayName();
String email = account.getEmail();
googleProfilName.setText(name);
googleProfilEmail.setText(email);
if (account.getPhotoUrl() != null) {
String img_url = account.getPhotoUrl().toString();
Glide.with(this).load(img_url).into(profilPic);
}
String idTest = account.getId();
firebaseAuthWithGoogle(account);
updateUI(true);
}
else{
updateUI(false);
}
}
...
private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
firebaseAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
System.out.println("signInWithCredential:onComplete:" + task.isSuccessful());
if (!task.isSuccessful()) {
System.out.println("signInWithCredential" + task.getException());
Toast.makeText(SignIn.this, "Authentication failed.",Toast.LENGTH_SHORT).show();
}
}
});
}

您的Google OAuth客户端凭据应该用于Web应用程序,而不是Android。您的Google登录选项应该与下面的代码类似(它是C#,但非常接近Java源代码):
那么它应该可以工作了。也许你忘了在GoogleSignInOptions对象上请求IDToken()
试试看:
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build();
现在,您需要配置您的项目,以便在您的项目中添加GoogleSignin工具。这里是链接
仅链接的答案往往不好。我们的目标是,即使其中的链接断开,答案仍然有用。谢谢,我花了两个小时试图解决这个问题。创建Web应用程序类型的OAuth客户机Id就做到了。
