In my app users can login using different accounts and I want to show different data based on that but there is also a state that user hasn't logged in to any account. so I want to show two different layouts. first one containing the account data and the second showing a button to my login activity. I tried toggling the visibility of my button but when the user logs in the widget doesn't update.
xml of my widget:
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
android:initialKeyguardLayout="@layout/updating_chart_widget_iot"
android:initialLayout="@layout/updating_chart_widget_iot"
android:minHeight="250dp"
android:minWidth="250dp"
android:previewImage="@drawable/chart_widget_preview"
android:resizeMode="vertical"
android:updatePeriodMillis="60000"
android:widgetCategory="home_screen">
</appwidget-provider>
here is the code of my widget provider: please tell me which part am I doing worng...

You can force all the instances of your home screen widgets to refresh like this:
private void udpateWidgets() {
Intent intent = new Intent(this, IoTUpdatingChartWidget.class);
intent.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
int[] ids = AppWidgetManager.getInstance(getApplication())
.getAppWidgetIds(new ComponentName(getApplication(), IoTUpdatingChartWidget.class));
intent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_IDS, ids);
sendBroadcast(intent);
}
I cannot see the login and logout code, but it may just be a case of calling updateWidgets() when the session state changes.
