I am trying to initialize the applovin sdk for my react-native app per these instructions: https://developers.google.com/admob/android/mediation/applovin#step_3_import_the_applovin_sdk_and_adapter
On step 3, I am not sure how exactly to use the code AppLovinSdk.initializeSdk(context);. I put it in my MainActivity.java onCreate method, but I get a cannot find symbol error since AppLovinSdk is not defined. What exactly am I missing?
You need this at the top of your Java file
import com.applovin.sdk.AppLovinSdk;
By the way, there's example code here
But, you really should be using an Application class's onCreate rather than an Activity.

TruecallerSDK.getInstance().getUserProfile();
The above line is not working in Android Studio. Its the exact line copied from the Truecaller official docs. They that getUserProfile does not take any argument but when i write it like this, it doesn't work.
Please help! It requires a FragmentActivity or a Fragment method.
And i am writing this code in my onCreate in MainActivity
Im using react-native-facebook-login pacakge.
And following their instructions. But get undefined when I instantiate it.
Not sure what else I need to do here.
My init code is exactly as they have on the github.
var FBLogin = require('react-native-facebook-login');
var FBLoginManager = require('NativeModules').FBLoginManager;
But FBLoginManager always returns undefined.
Do I need to build a NativeModule named FBLoginManager for android?? Is there something Im missing? Or some java file, or Manifest.xml entry I need?
Also, when I look inside the react-native-facebook-login package. I see two java files in the android part
FacebookLoginModule.java
FacebookLoginPackage.java
Should I be referring to these packages instead in react-native like so..?
var FBLoginManager = require('NativeModules').FacebookLoginModule;
Or do they export the FBLoginManager as a function?
According to 2 people now, they were able to run the github example directly without any problems.
You must add some code to your Android project per instruction: https://github.com/magus/react-native-facebook-login/blob/master/android/README.md
I'm trying to create my first app with Android but I've encountered some problems.
Following a tutorial and making:
new android application -> blank activity
The default result should be:
With MainActivity.java and R.Java inside it.
But instead I've got this:
There are a lot of errors and the R.Java file is missing.
I can obtain a result similar to the tutorial one (with no errors), creating a new android application and unchecking create activity, but this time MainActivity.java under src is totally missing.
Maybe I could copy the MainActivity.java of the first project and put into the second one, but I prefer understand why it doesn't work.
Thanks for the help.
Best regards.
its import library problem
Right click on you application----->Android
under library view ,
check if you have this red error then remove the library and add it again
The method getWsUrl() is undefined for the type Configuration
for this line
AndroidHttpTransport _ht = new
AndroidHttpTransport(Configuration.getWsUrl());
how can ı solve it?
You probably imported the wrong Configuration. Right now, your import likely points to android.content.res.Configuration.
However, your code snippet suggests you're using (parts of) some Google Code project, androidzon. It has a webservice package that includes a Configuration class with the method you're looking for. It appears to mean something like 'get webservice url'. You will want to correct your import and/or add the missing classes/libraries to your Android project.
Do note that you appear to be using old code, as the latest revision of that Configuration class does not include the getWsUrl() anymore. In stead, there is a getServerAddress() method.
I'm attempting to create an Activity and unfortunately every time I want to grab one of my XML components it gives me a RunTimeException (NullPointer).
Anytime I use code such as:
TextView tv = (TextView) findViewById(R.id.myView); //I get the exception
The same happens for any components I attempt to find with that method. I can't quite figure out why. I know it isn't due to the Activity not being in the Manifest because it's the only Activity in the test app I made. (The one set up by default).
Oddly I can still use setContentView(R.id.myView). It just doesn't seem to want to find anything when using the findViewById method.
Info that might be of use:
I am currently using NetBeans as my IDE.
I have done multiple 'clean and builds' as was suggested in another question. Android -findViewById question
Has anyone run into this issue before? If so, what was the solution?
If need be, I can provide sample code of when this is happening.
Don't pass in a view ID to setContentView, pass in a layout resource ID:
setContentView(R.layout.layout_name);
If you still have problems, post your layout file.
It is very sure that you R.java is not properly generated.
Delete R.Java in netbeans IDE and Re-build the project.
Hope it resolves your query.
