I am Trying to use facebook login in My app but I am getting an error that Manifest Merger faild

I am getting this Error.
Error:Execution failed for task ':app:processDebugManifest'.
Manifest merger failed : Attribute activity#com.facebook.FacebookActivity#theme value=(#android:style/Theme.Translucent.NoTitleBar) from AndroidManifest.xml:28:13-72
is also present at [com.facebook.android:facebook-common:4.35.0] AndroidManifest.xml:32:13-63 value=(#style/com_facebook_activity_theme).
Suggestion: add 'tools:replace="android:theme"' to element at AndroidManifest.xml:25:9-35:20 to override.
This is my MainActivity.java file

androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.facebook.android:facebook-android-sdk:[4,5)'
}

Solution is to revert to previous FB SDK in build.gradle:
dependencies {
// ...
compile 'com.facebook.android:facebook-android-sdk:4.15.0'
}

delete this line: android:theme="#android:style/Theme.Translucent.NoTitleBar"
AndroidManifest.xml
<meta-data android:name="com.facebook.sdk.ApplicationId"
android:value="#string/facebook_app_id"/>
<activity android:name="com.facebook.FacebookActivity"
android:configChanges=
"keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="#string/app_name" />
<activity
<!-- If you want the custom tabs when the facebook website is oppened -->
android:name="com.facebook.CustomTabActivity"
android:exported="true">
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="#string/fb_login_protocol_scheme" />
</intent-filter>
</activity>
You'll see that with custom tabs enabled the facebook website will open with a tab in the top and it will occupy the whole screen. Without this the website will open like a pop up and you can still see the app in the background if you look at the corners.
Or if you want to keep this line you need to add tools:replace="android:theme" in your manifest. But I see no reason to keep this line (correct me if I am wrong).
<activity android:name="com.facebook.FacebookActivity"
android:configChanges=
"keyboard|keyboardHidden|screenLayout|screenSize|orientation"
android:label="#string/app_name"
android:theme="#android:style/Theme.Translucent.NoTitleBar"
tools:replace="android:theme"/>
For facebook login guide.
ADITIONAL
An additional tip while working with facebook login, you will notice that when you added the facebook dependecie, com.android.support:appcompat-v7:... gives a warning saying that you have dependecies with different versions. You need to override this dependencie in order to get rid of this error

onMapReady method not applying to Google Maps Display

I am looking to display a Google Maps Display on a fragment layout within android studio. I have already downloaded Google play services in the SDK and have made the appropriate changes to my gradle files (I Think). I have made some changes to the android manifest file as well to grant user permissions etc. At run time a google maps display renders but the lng and lat are set to 0 so when the map displays, it shows me an area around Africa. I have made methods in the java file such as onMapReady, which is supposed to display the map at a different location and have it more zoomed in. The onMapReady function calls another method called goToLocationZoom, which holds the required functionality to allow the map to move to this location but for some reason everytime I run it, it always stays to the area around Africa, even though I have changed the lng and lat values. I am following a tutorial to achieve this, and in there Activty_home.XML file, they have their layout to linear, whilst mine is set to constraint but I don't think this would cause the issue. Does anyone know how to display the map to the lng and lat values that I have specified in the java file?
Below is my Java file code:
com.example.cmpkbest.lifestylefitnessapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;

public class ViewLifestyles extends AppCompatActivity implements
GoogleMap mGoogleMap;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_lifestyles);
initMap();
}
private void initMap () {
MapFragment mapFragment = (MapFragment) getFragmentManager ().findFragmentById(R.id.mapFragment);
mapFragment.getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mGoogleMap = googleMap;
goToLocationZoom (53.408743, -2.984154, 15);
}
private void goToLocation (double lat, double lng) {
LatLng ll = new LatLng(lat, lng);
CameraUpdate update = CameraUpdateFactory.newLatLng(ll);
mGoogleMap.moveCamera(update);
}
private void goToLocationZoom (double lat, double lng, float zoom) {
LatLng ll = new LatLng(lat, lng);
CameraUpdate update = CameraUpdateFactory.newLatLngZoom(ll, zoom);
mGoogleMap.moveCamera(update);
}
}

app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintVertical_bias="0.084" />
</android.support.constraint.ConstraintLayout>

I also had a project doing same output. I handle it this way.
So first you have to initialize the map
if (mMap == null) {
mMap = ((MapFragment) getFragmentManager().findFragmentById(
R.id.map)).getMap();
// check if map is created successfully or not
if (mMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
Then i call setUpMap right after initializing it, not relying on onMapReady
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(
lastLocation.getLatitude(), lastLocation.getLongitude()), 15));
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
mMap.setIndoorEnabled(true);
mMap.setMyLocationEnabled(true);
Hope this helps

Maps not loading and only showing a blanck screen with google written at bottom in android studio

hi im unable to load maps and its only showing google logo at the bottom of the screen when i try to load it. Iv got the api key as per the procedure and mentioned it at the places where thyr supposed to be. still its showing me error. one of them is api key not activated. iv read everywhere but not got how to activate the api key since all the tutorials specify a page where u can manually activate the key, but i think google has updated from there and now that page doesnt exist anymore. if there are any other alternatives please suggest. im pasting my code below.

iv already passed 2 days in just reading and doing stuff and nothin is hapenin. pl help

If you have an error about API keys it is because you have not correctly followed this tutorial : https://developers.google.com/maps/documentation/android-api/signup?hl=en
Be sure that you have a corrct SHA-1 fingerprint, to get this you should follow those instructions :
How to get the SHA-1 fingerprint certificate in Android Studio for debug mode?

As seen on the Android docs : https://developers.google.com/android/reference/com/google/android/gms/maps/GoogleMap.OnMyLocationChangeListener
GoogleMap.OnMyLocationChangeListener is now deprecated. The tutorial you are using is simply already too old.
From the link above, you will be able to be redirected to newer tutorials and how-to guides (which will also solve the setMyLocationEnabled error).
EDIT : What I recommended is now deprecated, such is life in software development. If you're looking for the newest way of doing it, check out the Android documentations.

Cannot resolve symbol 'mapView' on android studio

After tons of tries I couldn't found how to solve this.
Android won't resolve the symbol 'mapView' on:
mMapView = (MapView) v.findViewById(R.id.mapView);
What i'm trying to do is to get google maps to work on the emulator.
I know this code is working on another PC, so my guess here that there's something else.. (a system issue or google maps api problem)
here's the code.
Can anyone help? Thank you..

with
mMapView = (MapView) v.findViewById(R.id.map);
as the id of your fragment is map. See the xml
