Trying to Logout using broadcastReceiver

Question

What am I doing Wrong?

Activity Flow: HomeActivity --> SettingActivity --> ProfileActivity

In ProfileActivity I have LogOut button. OnClick LogOut I doing...

 public void onLogout()
{
    //do this on logout button click
    Intent intent = new Intent();
    intent.setAction("com.package.ACTION_LOGOUT");
    this.sendBroadcast(intent);

}

And in SettingsActivity onCreate I am doing this...

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_settings);

    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction("com.package.ACTION_LOGOUT");
    LocalBroadcastManager.getInstance(this).registerReceiver(new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.d("onReceive","Logout in progress");
            //At this point we should start the login activity and finish this one.
            Intent gotoLogin = new Intent(SettingsActivity.this,Login_Activity.class);
            startActivity(gotoLogin);
            finish();
        }
    }, intentFilter);
}

I thought I will logout from the ProfileActivity but I not. What is wrong with this code.

Answer 1

Use intent flags to clear out your activity stack, refer this for more details https://developer.android.com/reference/android/content/Intent.html#FLAG_ACTIVITY_CLEAR_TASK

So you need to implement your onLogout() method like below and you are good to go

public void onLogout() {
    //do this on logout button click
    Intent logoutUser = new Intent(context, Login_Activity.class);
    logoutUser.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(logoutUser);
}

Note: Also clear your shared preference session or local databases related to user profile if you are using any of it
