No provider for Camera! injectionError

There's a problem with the auto generated import statement. You need: import { Camera, CameraOptions } from '@ionic-native/camera/ngx';

you need to install camera plugins first by using two commands

$ ionic cordova plugin add cordova-plugin-camera

$ npm install --save @ionic-native/camera

after that in your app.module.ts you need to import that plugins and change your provider

import { NgModule, ErrorHandler } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { IonicApp, IonicModule, IonicErrorHandler } from 'ionic-angular';
import { MyApp } from './app.component';
import { HttpModule } from '@angular/http';

import { AboutPage } from '../pages/about/about';
import { ContactPage } from '../pages/contact/contact';
import { HomePage } from '../pages/home/home';
import { TabsPage } from '../pages/tabs/tabs';

import { StatusBar } from '@ionic-native/status-bar';
import { SplashScreen } from '@ionic-native/splash-screen';
import { CamaraExampalePage } from "../pages/camara-exampale/camara-exampale";
import { Camera} from '@ionic-native/camera';
@NgModule({
  declarations: [
    MyApp,
    AboutPage,
    ContactPage,
    HomePage,
    TabsPage,
    CamaraExampalePage
  ],
  imports: [
    BrowserModule,
    HttpModule,
    IonicModule.forRoot(MyApp)
  ],
  bootstrap: [IonicApp],
  entryComponents: [
    MyApp,
    AboutPage,
    ContactPage,
    HomePage,
    TabsPage,
    CamaraExampalePage
  ],
  providers: [
    Camera,
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler}
  ]
})
export class AppModule {}

You need to set Camera as provider in app.module.ts

 import { Camera } from '@ionic-native/camera';//import in app.module.ts

 //...

 providers: [
    StatusBar,
    SplashScreen,
    {provide: ErrorHandler, useClass: IonicErrorHandler},
    Camera //here
  ]

While I Serve the project it shows Runtime Error

NOTE: Cordova plugins do not work in ionic serve.. You need to use emulator/device. Also, include your plugin code within this.platform.ready() and check if cordova is available using this.platform.is('cordova')

import { Platform } from 'ionic-angular'; //import Platform
//...
constructor(public platform:Platform){}
//...
takePhoto() {
    this.platform.ready().then(() => {
        if(this.platform.is('cordova')){
            this.camera.getPicture(this.options).then((imageData) => {
                // imageData is either a base64 encoded string or a file URI
                // If it's base64 (DATA_URL):
                let base64Image = 'data:image/jpeg;base64,' + imageData;
            }, (err) => {
                // Handle error
            });
        }
    })
}
