I have integrated the Facebook in my application which works well while logging in, but when I try to logout I get many errors which I couldn't resolve. There were similar questions asked in stack overflow (Facebook Log Out error in Android, Can't create handler inside thread which has not called Looper.prepare()), but solution for that posts didn't workout for me. Here is my code:
public class Main extends Activity {
DrawerLayout drawerlayout;
ListView LVdrawer;
ImageView toplogo;
View rL;
Facebook fb;
Handler handler;
@SuppressWarnings("deprecation")
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.navigation_drawer);
rL = findViewById(R.id.toplogoaction);
handler=new Handler();
drawerlayout = (DrawerLayout) findViewById(R.id.drawer_layout);
LVdrawer = (ListView) findViewById(R.id.left_drawer);
LVdrawer.setAdapter(new CustomAdapter(this, 0));
fb=new Facebook(getString(R.string.APP_ID));
get();
LVdrawer.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
TextView ttt = (TextView) view.findViewById(R.id.detail);
String s = (String) ttt.getText();
drawerlayout.closeDrawers();
switch (s) {
case "Now":
if(fb.isSessionValid()){
Runnable runnable=new Runnable() {
@Override
public void run() {
handler.post(new Runnable() {
@Override
public void run() {
// TODO Auto-generated method stub
try {
Toast.makeText(getApplicationContext(), "Loggedout", Toast.LENGTH_SHORT).show();
fb.logout(getApplicationContext());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
// TODO Auto-generated method stub
}
};
new Thread(runnable).start();
}
break;
}
}
});
}
@SuppressWarnings("deprecation")
private void get() {
SharedPreferences Logininfo = getSharedPreferences("accesstoken", MODE_PRIVATE);
if (Logininfo.getString("access_token", null) != null) {
fb.setAccessToken(Logininfo.getString("access_token", null));
if (Logininfo.getLong("access_expires", 0) != 0)
fb.setAccessExpires(Logininfo.getLong("access_expires", 0));
}
}
}
