我正尝试在Android中使用Google Plus登录。当我按下Google Plus按钮时，它会给我一个需要选择的配置文件。选择google plus帐户后，会调用onConnected（）方法。然后我正在尝试获取用户数据。但我得到例外说法
Error requesting visible circles: Status{statusCode=NETWORK_ERROR, resolution=null}
这是我写的完整代码：
public class LoginActivity extends AppCompatActivity implements View.OnClickListener, GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, ResultCallback<People.LoadPeopleResult>
{
private GoogleApiClient mGoogleApiClient;
private ConnectionResult mConnectionResult;
private boolean mIntentInProgress;
private boolean mSignInClicked;
private static final int REQUEST_RESOLVE_ERROR = 1001;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_login);
mBtnGPlus = (SignInButton)findViewById(R.id.btn_sign_in);
mBtnGPlus.setOnClickListener(this);
mBtnGPlus.setSize(SignInButton.SIZE_STANDARD);
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(Plus.API, Plus.PlusOptions.builder().build())
.addScope(Plus.SCOPE_PLUS_PROFILE)
.addScope(Plus.SCOPE_PLUS_LOGIN)
.build();
}
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
@Override
public void onClick(View v)
{
if(v == mBtnGPlus)
{
onGPlusLogin();
}
}
private void onGPlusLogin()
{
Logger.d("button clicked");
if (!mGoogleApiClient.isConnecting()) {
mSignInClicked = true;
Logger.d("connecting gplus");
resolveSignInError();
}
}
private void resolveSignInError() {
Logger.d("resolveSignInError");
if (mConnectionResult.hasResolution())
{
Logger.d("inside hasResolution");
try {
mIntentInProgress = true;
mConnectionResult.startResolutionForResult(this, RC_SIGN_IN);
} catch (IntentSender.SendIntentException e)
{
Logger.d("exception came "+e.getMessage());
mIntentInProgress = false;
mGoogleApiClient.connect();
}
}
}
@Override
public void onResult(People.LoadPeopleResult peopleData) {
Logger.d("status code onResult " +peopleData.getStatus().getStatusCode());
if (peopleData.getStatus().getStatusCode() == CommonStatusCodes.SUCCESS) {
PersonBuffer personBuffer = peopleData.getPersonBuffer();
try {
int count = personBuffer.getCount();
for (int i = 0; i < count; i++) {
Logger.d("Display name: " + personBuffer.get(i).getDisplayName());
}
} finally {
personBuffer.release();
}
} else {
Logger.d("Error requesting visible circles: " + peopleData.getStatus());
}
}
@Override
public void onConnectionFailed(ConnectionResult result) {
if (!mIntentInProgress) {
// Store the ConnectionResult for later usage
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();
}
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Logger.d("OnActivity result:::: " + resultCode);
if (requestCode == RC_SIGN_IN)
{
Logger.d("OnActivity result 5555:::: " + resultCode);
if (resultCode != RESULT_OK)
{
Logger.d("OnActivity result 666666 " + resultCode);
mSignInClicked = false;
}
mIntentInProgress = false;
if (!mGoogleApiClient.isConnecting()) {
Logger.d("OnActivity result::: 777777 " + resultCode);
mGoogleApiClient.connect();
}
}
}
@Override
public void onConnectionSuspended(int arg0) {
Logger.d("onConnectionSuspended:::: ");
mGoogleApiClient.connect();
}
@Override
public void onConnected(Bundle arg0) {
mSignInClicked = false;
Logger.d("OnConnected:::: ");
Plus.PeopleApi.loadVisible(mGoogleApiClient, null)
.setResultCallback(this);
Logger.d("OnConnected:::: "+(Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) == null));
if (Plus.PeopleApi.getCurrentPerson(mGoogleApiClient) != null) {
Person currentPerson = Plus.PeopleApi.getCurrentPerson(mGoogleApiClient);
String personName = currentPerson.getDisplayName();
String personGooglePlusProfile = currentPerson.getUrl();
}
}
