我正在尝试从Facebook和Google API登录，Google API运行正常，Facebook登录出现问题，所有内容都在Facebook开发人员控制台上设置，我的应用程序也正常运行。
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。
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();
progressDialog.setCancelable(false);
progressDialog.setMessage("Loading...");
LoginManager.getInstance().logInWithReadPermissions(opening.this, Arrays.asList("email", "public_profile"));
LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Log.d(TAG2, "facebook:onSuccess:" + loginResult);
handleFacebookAccessToken(loginResult.getAccessToken());
setFbData(loginResult);
progressDialog.dismiss();
}
@Override
public void onCancel() {
Log.d(TAG2, "facebook:onCancel");
Toast.makeText(getApplicationContext(),"facebook:oncancel",Toast.LENGTH_LONG).show();
progressDialog.dismiss();

我正在使用以下方法进行fb登录，根据我们的知识，我们已经为我们测试了所有边界条件及其工作正常，并且从未面临任何挑战。
//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();
}
答案 1 :(得分：0)
可以明显看出，在logcat中无法看到访问令牌。那就是为什么您看到token:ACCESS_TOKEN_REMOVED
答案 2 :(得分：0)
原因是，您在方法Auth中混合了mAuth和handleFacebookAccessToken(AccessToken token)。
问题已经自我介绍onCreate()：
mAuth = FirebaseAuth.getInstance();
Auth = FirebaseAuth.getInstance();
删除Auth，并在所有地方使用名为mAuth的实例。
答案 3 :(得分：0)
尝试使用onSuccess()方法调用意图
@Override
public void onSuccess(LoginResult loginResult) {
Log.d(TAG2, "facebook:onSuccess:" + loginResult);
handleFacebookAccessToken(loginResult.getAccessToken());
setFbData(loginResult);
progressDialog.dismiss();
//call activity here
startActivity(new Intent(MainActivity.class));
}
答案 4 :(得分：0)
在调试模式下，您必须启用访问令牌的日志记录。因此，添加此行
if (BuildConfig.DEBUG) {
FacebookSdk.setIsDebugEnabled(true);
FacebookSdk.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
}
LoginManager.getInstance().registerCallback(callbackManager, new
FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
final GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
try {
if (object.has("id")) {
handleSignInResultFacebook(object); // Parse the json object for user details
} else {
Logger.e("FBLOGIN_FAILD", String.valueOf(object));
}
} catch (Exception e) {
e.printStackTrace();
dismissDialogLogin();
}
}
});
final Bundle parameters = new Bundle();
parameters.putString("fields", "name,email,id,picture.type(large)");
request.setParameters(parameters);
request.executeAsync();
}
@Override
public void onCancel() {
Logger.e("FBLOGIN_FAILD", "Cancel");
}
@Override
public void onError(FacebookException error) {
Logger.e("FBLOGIN_FAILD", "ERROR", error);
}
});
