Trying to create native module for react-native. I have all the dependencies needed and I followed the instructions user com mobile sdk installation
in project/android/build.gradle
allprojects {
repositories {
…
maven {
url 'https://android-sdk.user.com'
}
}
}
in project/android/app/build.gradle
dependencies {
implementation 'com.user:android-sdk:1.0.0'
}
then i created file in project/app/src/main/java/com/my_app/UserComModule.java
package com.my_app;
import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.bridge.ReactContext;
import com.facebook.react.bridge.ReactContextBaseJavaModule;
import com.facebook.react.bridge.ReactMethod;
import java.util.Map;
import java.util.HashMap;
import com.user.UserCom;
public class UserComModule extends ReactContextBaseJavaModule {
private static ReactApplicationContext reactContext;
#Override
public void onCreate() {
super.onCreate();
new UserCom.Builder(
this,
"api_secret", //your api secret key generated in User.com webpanel details
"https://<your_app_subdomain>.user.com"
)
.trackAllActivities(true) // false by default
.openLinksInChromeCustomTabs(true) // true by default
.setCustomTabsBuilder(getCustomTabsBuilder())
.build();
}
}
When i run i get: cannot find symbol import com.user.UserCom;
You're importing UserCom, and that module is not availabe, as you've mentioned you had created the file UserComModule in that directory, either create UserCom class or delete this line from UserComModule
import com.user.UserCom;

I am trying to extend OpenTelemetry java agent and I don't see any indication it is trying to load my jar.
I am running the following cmd:
java -javaagent:../src/main/resources/opentelemetry-javaagent.jar -Dotel.javaagent.configuration-file=../src/main/resources/agent-prp.properties -jar simple-service-1.0-SNAPSHOT-jar-with-dependencies.jar
my config file is (the attributes are working):
otel.javaagent.extensions=/Users/foo/source/simple-service/src/main/resources/span-processor-1.0-SNAPSHOT.jar
otel.resource.attributes=service.name=foooBarr
my extension is:
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;
import io.opentelemetry.context.Context;
import io.opentelemetry.sdk.common.CompletableResultCode;
import io.opentelemetry.sdk.trace.ReadWriteSpan;
import io.opentelemetry.sdk.trace.ReadableSpan;
import io.opentelemetry.sdk.trace.SpanProcessor;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.HashMap;
import java.util.Map;
public class FooSpanProcessor implements SpanProcessor {
private static final ObjectMapper objMapper = new ObjectMapper();
private static final Logger log = LoggerFactory.getLogger(FooSpanProcessor.class);
#Override
public void onStart(Context parentContext, ReadWriteSpan span) {
log.error("fffffffffff");
span.setAttribute("fooToken", FooProperties.INSTANCE.fooToken);
span.setAttribute("service.name", FooProperties.INSTANCE.serviceName);
span.setAttribute("runtime", FooProperties.INSTANCE.javaVersion);
span.setAttribute("tracerVersion", "0.0.1");
span.setAttribute("framework", FooProperties.INSTANCE.frameWork);
span.setAttribute("envs", FooProperties.INSTANCE.environment);
span.setAttribute("metaData", FooProperties.INSTANCE.metadata);
}
#Override
public boolean isStartRequired() {
return true;
}
#Override
public void onEnd(ReadableSpan span) {
}
....
I don't see any indication that my extension is loaded, I don't see any of my parameters on the produced spans. can any body help me?
"otel.javaagent.extensions" is not supported in the config file. add it with -D.
add the span processor to a config call implementing sdkTracerProviderConfigurer
I'm trying to compile an app that utilizes Expo on Android Studio, however, every time I try I get the following error message:
\android\app\src\main\java\com\profileid\MainActivity.java:2: error: class, interface, or enum expected
package com.projectname;
I just upgraded to Expo SDK 43 and migrated from react-native-unimodules.
My MainActivity.java looks like this:
import expo.modules.ReactActivityDelegateWrapper;
package com.projectname;
import android.os.Bundle;
import com.facebook.react.ReactActivity;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;
import expo.modules.splashscreen.singletons.SplashScreen;
import expo.modules.splashscreen.SplashScreenImageResizeMode;
public class MainActivity extends ReactActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// SplashScreen.show(...) has to be called after super.onCreate(...)
// Below line is handled by '#expo/configure-splash-screen' command and it's discouraged to modify it manually
SplashScreen.show(this, SplashScreenImageResizeMode.CONTAIN, ReactRootView.class, false);
}
/**
* Returns the name of the main component registered from JavaScript.
* This is used to schedule rendering of the component.
*/
#Override
protected String getMainComponentName() {
return "main";
}
#Override
protected ReactActivityDelegate createReactActivityDelegate() {
return new ReactActivityDelegateWrapper(this, new ReactActivityDelegate(this, getMainComponentName()) {
#Override
protected ReactRootView createRootView() {
return new RNGestureHandlerEnabledRootView(MainActivity.this);
}
});
}
}
Your first import statement and the package statement are out of order. The package statement must be the very first line of your file:
package com.projectname;
import android.os.Bundle;
import com.facebook.react.ReactActivity;
import com.facebook.react.ReactActivityDelegate;
import com.facebook.react.ReactRootView;
import com.swmansion.gesturehandler.react.RNGestureHandlerEnabledRootView;
import expo.modules.ReactActivityDelegateWrapper;
import expo.modules.splashscreen.singletons.SplashScreen;
import expo.modules.splashscreen.SplashScreenImageResizeMode;
Please HELP!!
I'm working on an app in react-native that involves using a native Calendar module. I'm trying to register this module with react native and I keep getting this error.
This is how I've registered the module in MainApplication.java:
#Override
protected List<ReactPackage> getPackages() {
List<ReactPackage> packages = new PackageList(this).getPackages();
packages.add(new ModuleRegistryAdapter(mModuleRegistryProvider));
packages.add(new MyAppPackage());
return packages;
}
This is the MyAppPackage.java file I've created using the tutorial here, https://reactnative.dev/docs/native-modules-android#register-the-module-android-specific.:
package com.chowtime; // replace your-app-name with your app’s name
import com.facebook.react.ReactPackage;
import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.uimanager.ViewManager;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class MyAppPackage implements ReactPackage {
#Override
public List<ViewManager> createViewManagers(ReactApplicationContext reactContext) {
return Collections.emptyList();
}
#Override
public List<NativeModule> createNativeModules(
ReactApplicationContext reactContext) {
List<NativeModule> modules = new ArrayList<>();
modules.add(new CalendarModule(reactContext));
return modules;
}
}
Note: This app was previously created using the managed-workflow on expo and was ejected to the bare workflow. This is the directory for the relevant files:
I came across this same error. It seems like the docs on how to create/use native modules in react native are missing a step.
In the MainApplication.java file you need to import 'MyAppPackage'.
import com.your-app-name.MyAppPackage;
Without importing it the 'MainApplication' file it won't know what MyAppPackage is referring to hence the cannot find symbol error.
Is this as simple as an import problem?
I noticed your MyAppPackage class is defined here:
package com.chowtime; // replace your-app-name with your app’s name
But your MainApplication error message seems indicate a sub-package, specifically "chowtime.chowtime". Did you mean for both chowtimes?
com.chowtime.chowtime.MainApplication
I was getting a successful build with android in React Native until I added these:
"appcenter-analytics": "2.1.0",
"appcenter-crashes": "2.1.0",
I am on:
"react": "16.8.6",
"react-native": "0.60.4",

The MainApplication.java file is inside of android/main/java/com/nfibengage/MainApplication.java:

SoLoader.init(this, /* native exopackage */ false);
}
}
I tried importing it into PackageList.java like so:
import com.nfibengage.MainApplication;
but I continue to get the same error. If anyone can walk me through where did this PackageList.java file come from and how do I get this working again short of just completely removing appcenter-analytics and appcenter-crashes.
Please make sure your installation order is the same as the following.
Add the App Center SDK modules
npm install appcenter appcenter-analytics appcenter-crashes --save-exact
or
yarn add appcenter appcenter-analytics appcenter-crashes --exact
Integrate the SDK automatically
react-native link appcenter
react-native link appcenter-analytics
react-native link appcenter-crashes
App Center SDK does not set up mocks automatically for App Center modules during the linking process. If you are using Jest test framework in your application and experience errors caused by the App Center SDK while running tests with Jest, add the following to the jest section of package.json file (include only modules in use):
"setupFiles": [
"<rootDir>/node_modules/appcenter/test/AppCenterMock.js",
"<rootDir>/node_modules/appcenter-analytics/test/AppCenterAnalyticsMock.js",
"<rootDir>/node_modules/appcenter-crashes/test/AppCenterCrashesMock.js",
"<rootDir>/node_modules/appcenter-push/test/AppCenterPushMock.js"
]
Edit the project's android/app/src/main/assets/appcenter-config.json and replace the YOUR_APP_SECRET placeholder value with your App Center project's application secret.
do one think only
goto your folder structure.
2.Add a file yarn-error.log
there will not be any problem your project will start well.
I tried to run an android project in Cordova with self-build plugin,
Heres the code in JS and java for the plugin
var cordova = require('cordova');
var Carrier = function() {};
Carrier.prototype.getCarrierCode = function(success, error) {
cordova.exec(success, error, 'CarrierPlugin', 'getCarrierCode', []);
};
var carrier = new Carrier();
module.exports = carrier;
this is the java code:
import org.apache.cordova.CordovaPlugin;
import org.apache.cordova.CallbackContext;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import java.util.Date;
import android.app.Activity;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.CallLog;
import android.content.ContentResolver;
public class CarrierPlugin extends CordovaPlugin{
public static final String TAG = "CarrierPlugin";
public static final String ACTION_GET_CARRIER_CODE = "getCarrierCode";
//public TelephonyManager tm;
#Override
public void initialize(CordovaInterface cordova, CordovaWebView webView) {
// TODO Auto-generated method stub
super.initialize(cordova, webView);
}
#Override
public boolean execute(String action, CordovaArgs args,
CallbackContext callbackContext) throws JSONException{
callbackContext.success("run it");
return true;
}
}
the error I got is "cannot find symbol :"
the strange thing is that, even if I change the code in the CarrierPlugin.java(delete the JSONException in line 16), it reported the same error.
My Eclipse says, you should import CordovaInterface, CordovaWebView and CordovaArgs.
And you might be missing package declaration as well, depending wherever you want to put your plugin's java files, such as:
package com.yourdomain.etc in the very first line of your Java file.
