我尝试使用firebase实现Google登录。我已经阅读了文档并观看了几个视频，但没有一个能够工作。每当我点击Google登录按钮时都没有任何反应。成功登录后，我希望它能够导致主要活动。我的应用程序从登录活动启动。
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();
}
// ...
}
});
}
}
这就是我的gradle看起来像：
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'
这是我的代码：
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();
}
}
});
}
这个blog提供了一步一步的指导
添加这些依赖项：
