我从上到下跟着firebase documentation,并为我的应用实施了一个简单的Google登录选项。但是,当我尝试登录时,该流程在选择Google帐户后停止,并导致onActivityResult方法中出现错误:
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
if (result.isSuccess()) {
// Google Sign In was successful, authenticate with Firebase
GoogleSignInAccount account = result.getSignInAccount();
firebaseAuthWithGoogle(account);
} else {
//THE CODE BREAKS HERE
// Google Sign In failed, update UI appropriately
}
}
代码在if (result.isSuccess())
条件下中断。进一步详细说明,这是我在完成文档后实现的完整代码:
的onCreate:
public class TestLogin extends AppCompatActivity {
private SignInButton mGoogleBtn;
private static int RC_SIGN_IN = 226;
private GoogleApiClient mGoogleApiClient;
private String TAG = "Checkmate";
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test_login);
mAuth = FirebaseAuth.getInstance();
mAuthListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
if(firebaseAuth.getCurrentUser() != null){
//success
}
}
};
mGoogleBtn = (SignInButton) findViewById(R.id.googleBtn);
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken("MY_CLIENT_ID-MY_CLIENT_ID.apps.googleusercontent.com")
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(getApplicationContext())
.enableAutoManage(this, new GoogleApiClient.OnConnectionFailedListener() {
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
//Failed
}
})
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
mGoogleBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
statusMessage.setText("Loading..");
signIn();
}
});
}
signIn方法:
点击 Google登录按钮后会调用SignIn方法:
private void signIn() {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
}
onActivityResult:
在单击按钮后收到结果时会调用onActivityResult。这是发生错误的地方:
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
if (result.isSuccess()) {
// Google Sign In was successful, authenticate with Firebase
GoogleSignInAccount account = result.getSignInAccount();
firebaseAuthWithGoogle(account);
} else {
//THE CODE BREAKS HERE
// Google Sign In failed, update UI appropriately
}
}
}
处理Google的Firebase登录代码:
此方法永远不会被调用,因为代码在onActivityResult条件下中断。
private void firebaseAuthWithGoogle(final GoogleSignInAccount acct) {
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful()) {
Toast.makeText(TestLogin.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
}
}
});
}
@Override
protected void onStart() {
super.onStart();
mAuth.addAuthStateListener(mAuthListener);
}
清单:
是的,我将google_services.json文件添加到/ app目录
是的,我在Google凭据页面中创建了一个新的OAuth客户端密钥
这是我的傻瓜:
dependencies {
compile 'com.google.android.gms:play-services:9.6.1'
compile 'com.google.firebase:firebase-core:9.6.1'
compile 'com.google.firebase:firebase-database:9.6.1'
compile 'com.google.firebase:firebase-auth:9.6.1'
compile 'com.google.firebase:firebase-storage:9.6.1'
}
apply plugin: 'com.google.gms.google-services'
并..
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.1.3'
classpath 'com.google.gms:google-services:3.0.0'
}
}

在我之前使用Firebase FriendlyChat的测试应用中,我在登录时遇到了类似的失败,但我已经通过google API控制台(https://console.developers.google.com/apis/credentials?project=)解决了这个问题,然后下载了“client_secret.json”(在我的情况下,我需要为您的Android客户端重命名下载的文件名“client_secret_xxxxx.json”,将此文件放在AndroidStudio项目的“/ src / main / resources”下(如果不存在则创建“resources”文件夹)然后尝试编译并运行再次使用您的Android应用。
摘要:您需要2个json文件:Firebase Console中的“google-services.json”和Google API控制台中的“client_secret.json”。
希望这可以解决您的问题。

转到firebase控制台并首先启用登录提供程序。 https://console.firebase.google.com/u/2/project/ipay-71f01/authentication/providers
我有同样的问题,但这是我的解决方案。 感谢

确保您已输入签名密钥库的SHA1。 这是指南https://developers.google.com/android/guides/client-auth
你必须找到两个目录, 1.已安装JDK的目录 2. .android
如果您使用的是Windows,'。android'文件夹可能放在'C:\ Users \ username \'中,而JDK目录可能放在'C:\ Users \ Program files \ java \'中。< / p>
在我的情况下,我的操作系统是Windows,所以首先我正在寻找我的jdk文件夹。
在'jdk_folder \ bin \'中你会找到'keytool.exe'并且我使用了这个命令
'。\ keytool -exportcert -list -v -alias androiddebugkey -keystore C:\ Users \ sgc109 \ .android \ debug.keystore”。
然后,复制SHA1密钥并粘贴到firebase控制台(设置 - 一般 - 我的应用程序 - SHA证书指纹(?)'(我住在韩国,因此菜单的名称可能与我不同)并且它有效:)
