i want to send current location to specific people in my firebase database when a button is clicked. These people change from device to device depending on which people the user has selected to get notification about the sender's location. I have a clue on what's required of me to do but i can't seem to figure it out.
This is the class i used to read the user's current location:
and in my menuActivity i want to call the latitude and the longitude when sendLoc button is clicked
public class MenuActivity extends AppCompatActivity

#Override
public void onClick(View view) {
Location l = gt.getLocation();

i want the location to be stored or opened on the history class now i am not sure how to get the location from the menuactivity class -> Emergency_Contacts then to -> history where it's going to be displayed.
Why if change mSwitch1 or mSwitch2 or mSwitch3, change All Switchs? If you leave one Switch in Activity, everything works.

Actually, I have converted WordPress site into an android app. In WordPress site there is some add available on the site which is created in javascript, and when data is fetched into the android app as a webview, there is some space is shown in place of that ads. I want to remove it or want to add AdMob ads there. How could it be possible? Please help me regarding this.
Thanks in advance.

I'm trying to port materialprime to primefaces 6. I already updated the widgets to use core.js and components.js but I have a problem rendering the materialprime. selectOne is not rendering also the jsf selectOneMenu is not rendering only the priemfaces SelectOneMenu works, the console says:
widget not available: selectOne
Any ideas?
