问题描述
public class SignIn extends AppCompatActivity {
$ b $ private FirebaseAuth mAuth;
私有FirebaseAuth.AuthStateListener mAuthListener;
private static final String TAG =SignInActivity;
private static final int RC_SIGN_IN = 9001;
GoogleApiClient mGoogleApiClient;
私人静态按钮googleSignIn;
@Override
protected void onCreate（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）;
setContentView（R.layout.activity_sign_in）;
//配置Google Sign In

$ b $ p $这是我的gradle的样子： compile'com.google.firebase：firebase-database：9.2.1'
compile'com.google.firebase：firebase -core：9.2.1'
compile'com.google.firebase：firebase-auth：9.2.1'
compile'com.google.android.gms：play-services-auth：9.2.1 '
解决方案这是我的代码：
保护无效signInwithGoogle（）{
GoogleSignInOptions gso = new GoogleSignInOptions.Builder（GoogleSignInOptions.DEFAULT_SIGN_IN）
.requestIdToken（getString（ R.string.default_web_client_id））
.requestEmail（）
.build（）;
mGoogleApiClient = new GoogleApiClient.Builder（getActivity（））
.enableAutoManage（getActivity（），this）
.addApi（Auth.GOOGLE_SIGN_IN_API，gso）
.build（）;
意图signInIntent = Auth.GoogleSignInApi.getSignInIntent（mGoogleApiClient）;
startActivityForResult（signInIntent，RC_SIGN_IN）;
$ b @Override
public void onActivityResult（int requestCode，int resultCode，Intent data）{
super.onActivityResult（requestCode，resultCode，data）;
if（requestCode == RC_SIGN_IN）{
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent（data）;
if（result.isSuccess（））{
GoogleSignInAccount acct = result.getSignInAccount（）;
//使用
String personName = acct.getDisplayName（）;
String personEmail = acct.getEmail（）;
String personId = acct.getId（）;
Uri personPhoto = acct.getPhotoUrl（）;
String personPhoneURL = acct.getPhotoUrl（）。toString（）;
//用户用户=新用户（）;
// user.setUsername（personName）;
// user.setEmail（personEmail）;
// user.setPersonId（personId）;
// user.setPersonProfileUrl（personPhoneURL）;
// user.setSignedInWithGoogle（true）;
// updateFirebaseData（user，personEmail）;
$ b $ gson gson = new GsonBuilder（）
.registerTypeAdapter（Uri.class，new UriSerializer（））
.create（）;
// String userData = gson.toJson（user）;
// EPreferenceManager.getSingleton（）。setUserdata（getActivity（），userData）;
firebaseAuthWithGoogle（acct）;
} else {
Toast.makeText（getActivity（），登录时遇到问题请重试，Toast.LENGTH_SHORT）.show（）;;
private void firebaseAuthWithGoogle（GoogleSignInAccount acct）{
auth = FirebaseAuth.getInstance（）;
AuthCredential凭证= GoogleAuthProvider.getCredential（acct.getIdToken（），null）;
auth.signInWithCredential（凭证）
.addOnCompleteListener（getActivity（），new OnCompleteListener< AuthResult>（）{
@Override
public void onComplete（@NonNull Task< AuthResult> task ）{
//如果登录失败，向用户显示一条消息，如果登录成功
// auth状态侦听器将被通知，逻辑处理
if（！task.isSuccessful（））{
Toast.makeText（getActivity（），Authentication failed。，
Toast。 LONGTH_SHORT）.show（）;
} else {
Toast.makeText（getActivity（），Authentication pass。，
Toast.LENGTH_SHORT）.show（）;
意图intent = new Intent（getActivity（），HomePageActiv） ity.class）;
startActivity（intent）;
getActivity（）。finish（）;
}
}
}）;
}
I tried implementing Google sign in using firebase . I have gone through the documentation and watched a couple of videos but none of them worked. Whenever I click the Google Sign In button nothing happens. Also after successful login I want it to lead to the main activity. My app launches from Sign In activity.
public class SignIn extends AppCompatActivity {
private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;
private static final String TAG = "SignInActivity";
private static final int RC_SIGN_IN = 9001;
GoogleApiClient mGoogleApiClient;
private static Button googleSignIn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sign_in);
// Configure Google Sign In
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build();
mAuth = FirebaseAuth.getInstance();
mAuthListener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
if (user != null) {
// User is signed in
Log.d(TAG, "onAuthStateChanged:signed_in:" + user.getUid());
} else {
// User is signed out
Log.d(TAG, "onAuthStateChanged:signed_out");
}
// ...
}
};
// ...
}
@Override
public void onStart() {
super.onStart();
mAuth.addAuthStateListener(mAuthListener);
}
@Override
public void onStop() {
super.onStop();
if (mAuthListener != null) {
mAuth.removeAuthStateListener(mAuthListener);
}
}
private void signIn() {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
}
@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 {
// Google Sign In failed, update UI appropriately
// ...
}
}
}
private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
Log.d(TAG, "firebaseAuthWithGoogle:" + acct.getId());
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
Log.d(TAG, "signInWithCredential:onComplete:" + task.isSuccessful());
// 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()) {
Log.w(TAG, "signInWithCredential", task.getException());
Toast.makeText(SignIn.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
}
// ...
}
});
}
}
This is what my gradle looks like:
compile 'com.google.firebase:firebase-database:9.2.1'
compile 'com.google.firebase:firebase-core:9.2.1'
compile 'com.google.firebase:firebase-auth:9.2.1'
compile 'com.google.android.gms:play-services-auth:9.2.1'
解决方案 This is my code :
protected void signInwithGoogle(){
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build();
mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
.enableAutoManage(getActivity(), this)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
if (result.isSuccess()) {
GoogleSignInAccount acct = result.getSignInAccount();
//TO USE
String personName = acct.getDisplayName();
String personEmail = acct.getEmail();
String personId = acct.getId();
Uri personPhoto = acct.getPhotoUrl();
String personPhoneURL = acct.getPhotoUrl().toString();
// User user = new User();
// user.setUsername(personName);
// user.setEmail(personEmail);
// user.setPersonId(personId);
// user.setPersonProfileUrl(personPhoneURL);
// user.setSignedInWithGoogle(true);
// updateFirebaseData(user,personEmail);
Gson gson = new GsonBuilder()
.registerTypeAdapter(Uri.class, new UriSerializer())
.create();
// String userData = gson.toJson(user);
// EPreferenceManager.getSingleton().setUserdata(getActivity(),userData);
firebaseAuthWithGoogle(acct);
} else {
Toast.makeText(getActivity(),"There was a trouble signing in-Please try again",Toast.LENGTH_SHORT).show();;
}
}
}
private void firebaseAuthWithGoogle(GoogleSignInAccount acct) {
auth = FirebaseAuth.getInstance();
AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
auth.signInWithCredential(credential)
.addOnCompleteListener(getActivity(), 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(getActivity(), "Authentication failed.",
Toast.LENGTH_SHORT).show();
}else{
Toast.makeText(getActivity(), "Authentication pass.",
Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getActivity(), HomePageActivity.class);
startActivity(intent);
getActivity().finish();
}
}
});
}
