问题描述
我正在尝试从Facebook和Google API登录，Google API正常运行，Facebook登录出现问题，所有内容都在Facebook开发人员控制台上进行了设置，并且我的应用程序也已启用.
I'm trying to login from Facebook and Google API, the Google API works fine, the problem arises with Facebook login, everything is setup on the Facebook developers console and my app is live as well.
问题是，每当用户单击登录按钮(这是一个自定义的ImageButton)时，ProgressBar就会显示出来，然后消失，并且该应用程序仍在同一活动中，而无需用户登录.
The problem is whenever user clicks on the login button (which is a customized ImageButton) the ProgressBar shows up and then it goes away and the app is still on the same activity without user being logged in.
该活动的完整代码为:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_opening);
progressDialog = new ProgressDialog(this);
mAuth = FirebaseAuth.getInstance();
Auth = FirebaseAuth.getInstance();
if (mAuth.getCurrentUser() != null) {
Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
finish();
}
GoogleSignInOptions gso = new GoogleSignInOptions
.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build();
mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
Google = (ImageView) findViewById(R.id.googleSignin);
Google.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
SIGN_IN_REQUEST = 1;
signIn();
progressDialog.setMessage("Loading...");
progressDialog.setCancelable(false);
progressDialog.show();
}
});
callbackManager = CallbackManager.Factory.create();
Facebook = (ImageView) findViewById(R.id.facebookSignin);
Facebook.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
SIGN_IN_REQUEST = 2;
progressDialog.show();

很长一段时间以来，我一直在寻找这个问题，但没有发现任何可以解决我问题的方法.
I've been looking around for this from quite some time and have not found anything which solves my problem.
推荐答案
我正在使用以下方法进行fb登录，根据我们的知识，我们已经测试了所有边界条件&现在对我们来说工作正常，而且从未面临任何挑战.
I am using the following method for fb login, As per our knolwedge, we have tested all the boundary conditions & its working fine for us now and never faced any challenge yet.
//on click of fb button
private void handleFBLogin() {
AccessToken accessToken = AccessToken.getCurrentAccessToken();
LoginManager.getInstance().logOut();
boolean isLoggedIn = accessToken != null && !accessToken.isExpired();
LoginManager.getInstance().logInWithReadPermissions(ActivityLogin.this, Arrays.asList("public_profile", "email"));
LoginManager.getInstance().registerCallback(callbackManager,
new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(final LoginResult loginResult) {
runOnUiThread(new Runnable() {
@Override
public void run() {
setFacebookData(loginResult, d);
}
});
}
@Override
public void onCancel() {
Toast.makeText(getApplicationContext(), "Canceled login ", Toast.LENGTH_SHORT); toast.show();
}
@Override
public void onError(FacebookException exception) {
d.dismiss();
if (exception instanceof FacebookAuthorizationException) {
if (AccessToken.getCurrentAccessToken() != null) {
LoginManager.getInstance().logOut();
handleFBLogin();
return;
}
}
Toast.makeText(getApplicationContext(), "ERROR " + exception.toString(), Toast.LENGTH_SHORT); toast.show();
PackageInfo info;
try {
info = getPackageManager().getPackageInfo([your package name], PackageManager.GET_SIGNATURES);
for (Signature signature : info.signatures) {
MessageDigest md;
md = MessageDigest.getInstance("SHA");
md.update(signature.toByteArray());
String something = new String(Base64.encode(md.digest(), 0));
//String something = new String(Base64.encodeBytes(md.digest()));
Log.e("hash key", something);
}
} catch (Exception e1) {
Log.e("name not found", e1.toString());
}
}
});
}
private void setFacebookData(final LoginResult loginResult) {
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
try {
final String firstName = response.getJSONObject().getString("first_name");
String lastName = response.getJSONObject().getString("last_name");
String id = response.getJSONObject().getString("id");
String email = null;
if (response.getJSONObject().has("email"))
email = response.getJSONObject().getString("email");
//put your code here
} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,email,first_name,last_name,gender");
request.setParameters(parameters);
request.executeAsync();
}
