[英]Firebase Google Sigin Authentication failed
我正在將此代碼用於使用Firebase的信息。
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 {
Toast.makeText(SignIn.this, "Authentication Went wrong ", Toast.LENGTH_SHORT).show();
}
}
}
private void firebaseAuthWithGoogle(GoogleSignInAccount account) {
AuthCredential credential = GoogleAuthProvider.getCredential(account.getIdToken(), null);
mAuth.signInWithCredential(credential)
.addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
// Sign in success, update UI with the signed-in user's information
Log.d("TAG", "signInWithCredential:success");
FirebaseUser user = mAuth.getCurrentUser();
//updateUI(user);
} else {
// If sign in fails, display a message to the user.
Log.w("TAG", "signInWithCredential:failure", task.getException());
Toast.makeText(SignIn.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
//updateUI(null);
}
// ...
}
});
}
但是,當我嘗試登錄時,它給出錯誤消息。 我在哪里做錯了?
我已經在我的應用程序Gradle中包括了firebaseAuth的依賴項compile 'com.google.firebase:firebase-auth:11.0.2' compile 'com.google.android.gms:play-services-auth:11.0.2'
在Firebase控制台中啟用了Google作為登錄方法。
在我的logout.class
我正在使用此代碼`button =(Button)findViewById(R.id.logout); mAuth = FirebaseAuth.getInstance();
mAuthlistener = new FirebaseAuth.AuthStateListener() {
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
if (firebaseAuth.getCurrentUser() == null) {
startActivity(new Intent(logout.this, SignIn.class));
}
}
};
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mAuth.signOut();
}
});
}`
但是,當我單擊它時,這將打開Sigin.class
但是當我們再次嘗試使用Sigin時,它會崩潰。
在Firebase控制台中創建Firebase項目時,請確保已使用添加的SHA1證書到Firebase項目中,並嘗試使用下面的代碼

讓我知道它是否有效。
對於LOgOUt,您必須像我在項目中一樣完成BottomNavigation布局。以下是xml代碼。
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.food.sheenishere.stark.profilemain">
<android.support.design.widget.BottomNavigationView
android:id="@+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="?android:attr/windowBackground"
app:menu="@menu/navigation" />
</LinearLayout>
這是Java代碼。
