Data transfer between the Activities of Android

Data transfer between the Activities of Android - java

I have problem I create small application with first get sms code if length it is greater than six go to activity B. Activity B show scan QR Code. Scan QR Code use library google play services vision to scan QR Code. Get value with barcode and make mix with sms code if value is correct go to Activity C if not go to activity A. My question how get value sms code and barcode value and where make ctrytography.
this is class with get sms code

I think you need to get into Intents:
https://developer.android.com/guide/components/intents-filters.html
sending:
String text = "some text here";
Intent i = new Intent(this, ActivityB.class);
i.putExtra("interesting_text", text);
startActivity(i);
receiving:
Intent intent = getIntent();
String text = intent.getExtras().getString("interesting_text");

How to change the location manager into fused location provider api?

I'm very new to android studio, and I'm working with an app that demands more of accuracy of location, first i used location manager but it provides not so accurate location of the user now i want to change it to fused location api but im confused with it, i don't know how to put it in my activity,I already search the net but nothing seems to have sense to me.
here is my Main Activity
public class MainActivity extends AppCompatActivity {
ContactDbAdapter contactDbAdapter;

I already put in my manifest the permissions and I also added the 'com.google.android.gms:play-services-location:10.0.0' in my gradle file. The issue now is i want to change the location manager into fused location provider api.

Since location provider is deprecated with LocationProviderClient in latest play services version but if you want to continue with the location provider here is the sample working activity code for location provider in activity
public class LocationActivity extends AppCompatActivity implements
GoogleApiClient.OnConnectionFailedListener, GoogleApiClient.ConnectionCallbacks,
LocationListener, GetAddressFromLatLng.LocationAddressResponse {
private LocationRequest mLocationRequest;

private FusedLocationProviderApi locationProvider = LocationServices.FusedLocationApi;
private GoogleApiClient mGoogleApiClient;
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

mGoogleApiClient.connect();

I notice you have two layouts open - double check that SignInButton from your comments is in activity_login as that is the one being searched, everything else seems to be in order

Zxing Bar code scanner issue in Android

I am working on a barcode scanner App where on button click in the first Activity, I am moving to the BarcodeScanner Activity where I am importing Zxing library functionalities. Once the scanning is completed, I am moving to a 3rd Activity where I am showing the scanned Results. On clicking a button in the 3rd activity, i am coming back to the 1st activity. For devices having Marshmallow, the code is running fine. But the issue is happening with devices having versions below marshmallow where after going back to the 1st activity from the 3rd Activity, when i am pressing again the button, the scanner activity is appearing but the camera is not starting. It just showing a blank page. Please help. Below I am posting my codes for all 3 Activities.

// check if the request code is same as what is passed here it is 2

Libgdx - How to implement loading screen in Android Launcher using ads

So I've created a game using Libgdx and the load times were practically non-existent, recently I added a Facebook leaderboard using the GDXFacebook extension which added a small overhead when loading up the app as it will auto login when loading but nothing that really effected load times. Now using and implementation from Libgdx I have added ads through Google play services to the main page of the game but it has made it so the initial load times is now a good 5 seconds.
My question is is there away to add the loading image to the android launcher class while it is loading to the main screen?
Thanks in advance!
Here is my Android launcher class and main game class.
Android Launcher:
public class AndroidLauncher extends AndroidApplication implements IActivityRequestHandler {
private static final String AD_UNIT_ID = "ca-app-pub-3940256099942544/6300978111";
private final int SHOW_ADS = 1;
private final int HIDE_ADS = 0;
private AdView adView;
protected Handler handler = new Handler() {
#Override
public void handleMessage(Message msg) {
switch (msg.what) {
case SHOW_ADS: {
adView.setVisibility(View.VISIBLE);
break;
}
case HIDE_ADS: {
adView.setVisibility(View.GONE);
break;
}
}
}
};
