我试图在我的Android应用中集成facebook和google plus登录，并且它们单独运行良好。
当我尝试将它们同时整合时，它们似乎工作正常。
这是我的结构流程：
1.LoginActivity ----＆gt;用户点击google +或facebook登录按钮。
这是我的LoginActivity：
public class GoogleLogin extends Activity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private static final int RC_SIGN_IN = 0;
private GoogleApiClient mGoogleApiClient;
private boolean mIntentInProgress;
private boolean mSignInClicked;
private ConnectionResult mConnectionResult;
public static GoogleLogin mContext;
private UiLifecycleHelper uiHelper;
Button fbutton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mContext = this;
uiHelper = new UiLifecycleHelper(this, statusCallback);
uiHelper.onCreate(savedInstanceState);
setContentView(R.layout.login);
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(Plus.API, PlusOptions.builder().build())
.addScope(Plus.SCOPE_PLUS_LOGIN)
.build();
findViewById(R.id.sign_in_button).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (v.getId() == R.id.sign_in_button
&& !mGoogleApiClient.isConnecting()) {
mSignInClicked = true;
resolveSignInError();
}
}
});
fbutton = (Button) findViewById(R.id.btnflogin);
findViewById(R.id.btnflogin).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// start Facebook Login
Session.openActiveSession(GoogleLogin.this, true, new Session.StatusCallback() {
// callback when session changes state
@Override
public void call(Session session, SessionState state, Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.newMeRequest(session, new Request.GraphUserCallback() {
// callback after Graph API response with user object
@Override
public void onCompleted(GraphUser user, Response response) {
if (user != null) {
Intent i = new Intent(GoogleLogin.this,MainActivity.class);
//Add your data from getFactualResults method to bundle
i.putExtra("Facebook", "Logged in using Facebook Account");
i.putExtra("LastName", user.getLastName());
i.putExtra("FirstName", user.getFirstName());
//Add the bundle to the intent
i.putExtras(i);
startActivityForResult(i, 1);
}
}
}).executeAsync();
}
}
});
}
});
}
private Session.StatusCallback statusCallback = new Session.StatusCallback() {
@Override
public void call(Session session, SessionState state,
Exception exception) {
if (state.isOpened()) {
Log.d("FacebookSampleActivity", "Facebook session opened");
} else if (state.isClosed()) {
Log.d("FacebookSampleActivity", "Facebook session closed");
}
}
};
@Override
public void onResume() {
super.onResume();
uiHelper.onResume();
}
@Override
public void onPause() {
super.onPause();
uiHelper.onPause();
}
@Override
public void onDestroy() {
super.onDestroy();
uiHelper.onDestroy();
}
@Override
public void onSaveInstanceState(Bundle savedState) {
super.onSaveInstanceState(savedState);
uiHelper.onSaveInstanceState(savedState);
}
private void resolveSignInError() {
if (mConnectionResult.hasResolution()) {
try {
mIntentInProgress = true;
startIntentSenderForResult(mConnectionResult.getResolution().getIntentSender(),
RC_SIGN_IN, null, 0, 0, 0);
} catch (SendIntentException e) {
// The intent was canceled before it was sent. Return to the default
// state and attempt to connect to get an updated ConnectionResult.
mIntentInProgress = false;
mGoogleApiClient.connect();
}
}
}
protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
uiHelper.onActivityResult(requestCode, responseCode, intent);
if (requestCode == RC_SIGN_IN) {
if (responseCode != RESULT_OK) {
mSignInClicked = false;
}
mIntentInProgress = false;
if (!mGoogleApiClient.isConnecting()) {
mGoogleApiClient.connect();
}
}
}
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
protected void onStop() {
super.onStop();
if (mGoogleApiClient.isConnected()) {
mGoogleApiClient.disconnect();
}
}
public void onConnectionFailed(ConnectionResult result) {
if (!mIntentInProgress) {
// Store the ConnectionResult so that we can use it later when the user clicks
// 'sign-in'.
mConnectionResult = result;
if (mSignInClicked) {
// The user has already clicked 'sign-in' so we attempt to resolve all
// errors until the user is signed in, or they cancel.
resolveSignInError();
}
}
}
public void onConnected(Bundle connectionHint) {
// We've resolved any connection errors. mGoogleApiClient can be used to
// access Google APIs on behalf of the user.
mSignInClicked = false;
Toast.makeText(this, "User is connected!", Toast.LENGTH_LONG).show();
if (Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) != null) {
Intent i = new Intent(getApplicationContext(),MainActivity.class);
Person currentPerson = Plus.PeopleApi.getCurrentPerson(mGoogleApiClient);
//Create the bundle
Bundle bundle = new Bundle();
//Add your data from getFactualResults method to bundle
bundle.putString("Google", "Logged in using Google Account");
bundle.putString("GoogleUsername", currentPerson.getDisplayName());
//Add the bundle to the intent
i.putExtras(bundle);
startActivity(i);
}
}
public void onConnectionSuspended(int cause) {
mGoogleApiClient.connect();
}
public void gplusSignout(View v){
//if (v.getId() == R.id.gPlusSignout) {
if (mGoogleApiClient.isConnected()) {
Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
mGoogleApiClient.disconnect();
//mGoogleApiClient.connect();
Log.d("Debug","Disconnected");
Toast.makeText(this, "User is disconnected!", Toast.LENGTH_LONG).show();
}
//}
}
}
这些让我感到困惑：
private void resolveSignInError() {
if (mConnectionResult.hasResolution()) {
try {
mIntentInProgress = true;
startIntentSenderForResult(mConnectionResult.getResolution().getIntentSender(),
RC_SIGN_IN, null, 0, 0, 0);
} catch (SendIntentException e) {
// The intent was canceled before it was sent. Return to the default
// state and attempt to connect to get an updated ConnectionResult.
mIntentInProgress = false;
mGoogleApiClient.connect();
}
}
}
protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
if (requestCode == RC_SIGN_IN) {
if (responseCode != RESULT_OK) {
mSignInClicked = false;
}
mIntentInProgress = false;
if (!mGoogleApiClient.isConnecting()) {
mGoogleApiClient.connect();
}
}
}
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
protected void onStop() {
super.onStop();
if (mGoogleApiClient.isConnected()) {
mGoogleApiClient.disconnect();
}
}
public void onConnectionFailed(ConnectionResult result) {
if (!mIntentInProgress) {
// Store the ConnectionResult so that we can use it later when the user clicks
// 'sign-in'.
mConnectionResult = result;
if (mSignInClicked) {
// The user has already clicked 'sign-in' so we attempt to resolve all
// errors until the user is signed in, or they cancel.
resolveSignInError();
}
}
}
我现在很震惊，我不确定我是否可以在ActivityResult中这样做：
要启动Facebook并转到下一个活动，这可以正常工作：
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}
但与此同时我有google + onActivity的结果。那么如何管理它们呢？
任何人都可以说我如何实现这一目标，以使两者都有效。
