I am trying to connect Android Studio with Firebase and I have some red lines and I don't know why. I am following instruction from this tutorial : https://www.youtube.com/watch?v=tOn5HsQPhUY
Could someone please tell me if I am doing something wrong and what?
Here is a picture of this
the Problem is that these commands are from an older firebase Version.
I recommend to take a look at the docs here:https://firebase.google.com/docs/database/android/start/
Try this code :
private DatabaseReference mRef;
mRef = FirebaseDatabase.getInstance().getReference();
You forgot to add dependencies for Firebase and maybe you forgot to take the latest Google Repository.
Place your specific dependency:
compile 'com.google.firebase:firebase-messaging:9.6.0'
Add import com.firebase.client.Firebase; in class and add compile 'com.firebase:firebase-client-android:2.5.0' in app (build.gradle)
Import the following:
import com.google.firebase.database.DataSnapshot;
import com.google.firebase.database.DatabaseReference;
import com.google.firebase.database.FirebaseDatabase;
import com.google.firebase.database.ValueEventListener;
guys i also had the same problem were i could not use Firebase class when trying to define a variable
try this
go to your App level build.gradle in the dependencies add
compile 'com.firebase:firebase-client-android:2.5.0
for some having newer versions of android you can replace compile with implementation

In my gradle.properties I have this:
android.useAndroidX=true
When I Make Project, I get BUILD SUCCESSFUL. From Android Studio, I go to Refactor > Migrate to AndroidX... I am getting 15 references in 9 files to be changed:
Reading https://medium.com/androiddevelopers/migrating-to-androidx-tip-tricks-and-guidance-88d5de238876, I see that the step 1 of the recommended approach to migrate is to Update to Support Library version 28. In order to do that, I want to know what Support Library version the code of my app is at. Where can I see that? In some of my .java files I have found the following:
import android.support.annotation.NonNull;
import android.support.v4.app.NotificationCompat;
import android.support.v7.app.AppCompatActivity;
import android.support.v4.content.ContextCompat;
import android.support.v4.app.ActivityCompat;
import android.support.v4.app.FragmentActivity;
import android.support.multidex.MultiDex;
In my app\build.gradle I have this: implementation 'com.android.support:multidex:1.0.3'.
Do any of the lines above reveals or helps to reveal the Support Library version that the code of my app is at? Thank you.
What it means is that they suggest upgrading all of the possible support libraries to 28.0.
Those are basically anything that starts with com.android.support:
e.g.:
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:gridlayout-v7:28.0.0'
The recommendation there is so the migration in the AS will have to do minimal guessing on how to migrate it.
So to stricly answer your question, the version you use is the version you have in gradle.files.
I'm followed some tuts for including the FB SDK
but when I want to import
import com.facebook.FacebookSdk;
I need this for FB analytics, so I'm created the class fbanalytic :
image here
and we see it's hidden i dont know fix it
and also someone his tell that class it's not important specialy in the latest version in fb sdk ,is that correct?
currently im using latest verion :facebook-android-sdk-4.22.1
Using the Facebook SDK:
Import the sdk by adding compile dependency to build.gradle file
dependencies {
compile 'com.facebook.android:facebook-android-sdk:4.+'
}
Now when you are trying to use something from Facebook's SDK it should be AUTOMATICALLY imported to your files.
In your example you are making a new Class that does uses AppEventsLogger that is part of Facebook SDK. The import statement that you presumably wrote (import com.facebook.FacebookSDK) is grey and second import statement clearly shows that it is importing form com.facebook.* SDK.
tldr: Android Studio imports from Facebook SDK as expected.
Add in build.gladle within dependencies bracket:
compile 'com.facebook.android:facebook-android-sdk:4.+'
Might be duplicate.
I'm following a tutorial and I've pulled the google gms git repository.
I'm getting an error "cannot resolve symbol android" when I import
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.gcm.GoogleCloudMessaging;
I have updated google play services. Here's my gradle -
...
compile 'com.google.android.gms:play-services-gcm:8.4.0'
}
Where am I going wrong??
Try This code. It's very simple and easy steps.
Link: https://github.com/googlesamples/google-services/tree/master/android/gcm/app/src/main/java/gcm/play/android/samples/com/gcmquickstart
Hope it works for you.
Check the base package and make sure the gradle is updated
I am 'lucky' to have been charged with maintaining a program developed by someone else, and I come across the following problem with an import statement:
import com.fizzbuzz.android.dagger.InjectingDialogFragment;
which Android Studio cannot resolve. I am totally new to dagger...
I have the following in build.gradle dependencies:
compile 'com.fizz-buzz:fb-android-dagger:1.0.1'
compile 'com.fizz-buzz:fb-android-bluetooth:1.0.3'
InjectingDialogFragment is not available in the version you are currently using. Please use compile 'com.fizz-buzz:fb-android-dagger:1.0.3' instead.
For better understating on how Dagger works you can use this blog http://antonioleiva.com/dagger-android-part-2/
I am new to Android development. I am learning to use Parse.com backend service and get stuck early on.
I am following tutorial to create application that uses Google Maps Android API v2. What I've done :
download sample
project from parse
Import AnyWall-android\Anywall folder from downloaded project to Android Studio
Rebuild project
Then I get a bunch of errors here :
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesClient;
import com.google.android.gms.common.GooglePlayServicesUtil;
import com.google.android.gms.location.LocationClient;
import com.google.android.gms.location.LocationListener;
import com.google.android.gms.location.LocationRequest;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap.CancelableCallback;
import com.google.android.gms.maps.GoogleMap.OnCameraChangeListener;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.CameraPosition;
import com.google.android.gms.maps.model.Circle;
import com.google.android.gms.maps.model.CircleOptions;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.LatLngBounds;
import com.google.android.gms.maps.model.Marker;
import com.google.android.gms.maps.model.MarkerOptions;
common, location, and maps highlighted red. The question is how to resolve these errors?
I appreciate any kind of help or direction (What should I check? Is it about missing library? If it is, what library should I add and where to get it?)
Can't find the class com.google.android.gms.location.LocationClient (android)
There is some problem with the last GPS lib. You have to use an older version than the latest(6.+). Try with an older version. I didn't see anything inside the doc deprecated or missing about the LocationClient.class...
compile 'com.google.android.gms:play-services:5.+'
I think the best solution is, add compile API on your Gradle. services-location has this method.
compile 'com.google.android.gms:play-services-maps:9.8.0'
compile 'com.google.android.gms:play-services-location:9.8.0'
if you wish to include other services, please refer here:
https://developers.google.com/android/guides/setup (scroll down)
Google Play Services is now modular, you can select the packages you want from it.
To get analytics add:
compile 'com.google.android.gms:play-services-analytics:7.3.0'
to you build.gradle's dependencies section
P.S
replace 7.3.0 with new version as they arrive, or replace with "+" to always get the latest
Android Studio is complaining that it can't find the Play Services library.
Follow the steps here to ensure Google Play Services SDK is installed (specifically, make sure 'Google Repository' is installed along with 'Google Play Services'): http://developer.android.com/google/play-services/setup.html#Install
Then, make sure the following is added to the dependencies{} block in your build.gradle:
compile 'com.google.android.gms:play-services:+'
Clean and rebuild.
Add this line you build.gradle in Gradle Scripts folder
dependencies {
compile 'com.google.android.gms:play-services:11.2.0'
}
with this i solved this issue.
Previous answers were correct.
But in gradle:3.0 the compile configuration is now deprecated and should be replaced by implementation or api.
Check out more information in the documentation - API and implementation separation.
Its just a common mistake in my case, I just remove default ""flutter:"" keyword in pubspec file while managing package
