登录失败后发布到Facebook的Android
作者：互联网
在我的postToFacebook()方法中.我检查了用户是否已连接,如果我在墙上发布了一个链接.当用户未登录时,会弹出facebook sdk登录进度,并使用我的凭据成功登录.我的问题是登录后我需要直接postonWall但postOnWall没有发布到Facebook.如果我已登录并发布,则会发布.请帮忙.这是我的完整postToFacebook代码.
public void postToFacebook(){
mAsyncRunner = new AsyncFacebookRunner(facebook);
loginToFacebook();
}
/**
* Function to login into facebook
* */
public void loginToFacebook() {
mPrefs = getPreferences(MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if (access_token != null) {
facebook.setAccessToken(access_token);
/*btnFbLogin.setVisibility(View.INVISIBLE);
// Making get profile button visible
btnFbGetProfile.setVisibility(View.VISIBLE);
// Making post to wall visible
btnPostToWall.setVisibility(View.VISIBLE);
// Making show access tokens button visible
btnShowAccessTokens.setVisibility(View.VISIBLE);*/
new loadingTask().execute();
System.out.println("one");
Log.d("FB Sessions", "" + facebook.isSessionValid());
}
if (expires != 0) {
facebook.setAccessExpires(expires);
}
if (!facebook.isSessionValid()) {
facebook.authorize(this,
new String[] { "email", "publish_stream" },
new DialogListener() {
@Override
public void onCancel() {
// Function to handle cancel event
}
@Override

// Edit Preferences and update facebook acess_token
SharedPreferences.Editor editor = mPrefs.edit();
editor.putString("access_token",
facebook.getAccessToken());
editor.putLong("access_expires",
facebook.getAccessExpires());
editor.commit();

解决方法:
我已经测试了这个代码用于发布Facebook SDK 3.0,这是有效的.
在当前项目中引用Facebook SDK 3.0 Library项目.
在String.xml文件中设置AppId：
<string name="app_id">123456789012345</string>
之后在清单文件中添加MetaTag：
<meta-data
android:name="com.facebook.sdk.ApplicationId"
android:value="@string/app_id" />
对于日志记录和注销,您只需使用Facebook登录按钮小部件“com.facebook.widget.LoginButton”即可.
此小部件自动管理会话,因此您不必担心这一点.
只需将此按钮放在Layout.xml文件中的正确位置即可.
像任何其他按钮一样初始化此按钮：
LoginButton authButton = (LoginButton) findViewById(R.id.YOUR_ID);
初始化后,在LoginButton上设置权限
authButton.setPublishPermissions(Arrays.asList("publish_stream","read_stream"));
并实现Login按钮小部件的setSessionStatusCallback方法：
authButton.setSessionStatusCallback(new Session.StatusCallback()
{
public void call(Session session, SessionState state,Exception exception)
{
// TODO Auto-generated method stub
if (session.isOpened())
{
Log.i(TAG, "Access Token" + session.getAccessToken());
Request.executeMeRequestAsync(session,new Request.GraphUserCallback() {
public void onCompleted(GraphUser user,Response response)
{
// TODO Auto-generated method stub
if (user != null)
{
Log.i(TAG, "User ID " + user.getId());
Log.i(TAG,"Email "+ user.asMap().get("email"));
}
}});
}
else
{
//This else condition will be executed when logout will be clicked.
}
}
});
以下是在Facebook上发布的方法.
private void publishStory(String status)
{
Session session = Session.getActiveSession();
if (session != null)
{
Bundle postParams = new Bundle();
postParams.putString("message", status);
Request.Callback callback = new Request.Callback()
{
public void onMalformedURLException(MalformedURLException e)
{
}
public void onIOException(IOException e)
{
}
public void onFileNotFoundException(FileNotFoundExceptione)
{
}
public void onFacebookError(FacebookError e)
{
}
public void onCompleted(Response response)
{
JSONObject graphResponse = response.getGraphObject().getInnerJSONObject();
String postId = null;
try
{
postId = graphResponse.getString("id");
}
catch (JSONException e)
{
Log.i("JSON", "JSON error " + e.getMessage());
}
FacebookRequestError error = response.getError();
Log.e("post response", response.toString());
if (error != null)
{
}
else
{
}
}
};
Request request = new Request(session, "me/feed", postParams, HttpMethod.POST, callback);
RequestAsyncTask task = new RequestAsyncTask(request);
task.execute();
}
}
