Log.d("FB Sessions", "" + facebook.isSessionValid());
}
if (expires != 0) {
facebook.setAccessExpires(expires);
}
if (!facebook.isSessionValid()) {
facebook.authorize(this,

@Override

});
}
public void logoutFromFacebook() {
mAsyncRunner.logout(this, new RequestListener() {
@Override
public void onComplete(String response, Object state) {
Log.d("Logout from Facebook", response);
if (Boolean.parseBoolean(response) == true) {
runOnUiThread(new Runnable() {

}
});
}
}
@Override
public void onIOException(IOException e, Object state) {
}
@Override
public void onFileNotFoundException(FileNotFoundException e,
Object state) {
}
@Override
public void onMalformedURLException(MalformedURLException e,
Object state) {
}
@Override
public void onFacebookError(FacebookError e, Object state) {
}
});
}
}`
当我点击注销按钮它说：
`
when i click the logout button it says: `
08-14 14:46:59.849: D/Image Button(284): button Clicked
08-14 14:46:59.869: D/Facebook-Util(284): GET URL: https://api.facebook.com/restserver.php? method=auth.expireSession&format=json
08-14 14:47:00.399: D/Logout from Facebook(284): {"error_code":101,"error_msg":"Invalid application ID.","request_args":[{"key":"method","value":"auth.expireSession"},{"key":"format","value":"json"}]}
`
推荐答案
使用此就为我工作
facebook.logout(this);
在Facebook的SDK Facebook.java
in Facebook SDK Facebook.java
public String logout(Context context) throws MalformedURLException, IOException {
Util.clearCookies(context);
Bundle b = new Bundle();
b.putString("method", "auth.expireSession");
String response = request(b);
setAccessToken(null);
setAccessExpires(0);
return response;
}
