.html

    <script src="node_modules/chart.js/src/chart.js"></script>  <canvas basechart height="200"         [datasets]="linechartdata"         [labels]="linechartlabels"         [options]="linechartoptions"         [colors]="linechartcolors"         [legend]="linechartlegend"         [charttype]="linecharttype"   ></canvas>

.module

    import { browsermodule } '@angular/platform-browser'; import { ngmodule } '@angular/core'; import { chartsmodule } 'ng2-charts/ng2-charts';  import { appcomponent } './app.component';  @ngmodule({   declarations: [     appcomponent   ],   imports: [     browsermodule,     chartsmodule   ],   providers: [],   bootstrap: [appcomponent] }) export class appmodule { }

updated code, page blank, have no errors in console message :

angular running in development mode. call enableprodmode() enable production mode.

chart.js needs wrapped work typescript. using import {chart} 'chart.js'; won't work. try different npm library one:

https://www.npmjs.com/package/ng2-charts

i've had success it. should fix issue.

you won't need import chart @ all.

just include cart in html. this:

 <canvas basechart height="200"         [datasets]="linechartdata"         [labels]="linechartlabels"         [options]="linechartoptions"         [colors]="linechartcolors"         [legend]="linechartlegend"         [charttype]="linecharttype"   ></canvas>

then access in component. this:

linechartdata: array<any>; linechartlabels: string[] = [..data..       ];    linechartoptions: = {     responsive: true,     animation: false,    };   linechartcolors: array<any> = [     { // grey       backgroundcolor: 'rgba(33,150,243,0.2)',       bordercolor: 'rgba(33,150,243,1)',       pointbackgroundcolor: 'rgba(33,150,243,1)',       pointbordercolor: '#fff',       pointhoverbackgroundcolor: '#fff',       pointhoverbordercolor: 'rgba(33,150,243,0.8)'     },     { // dark grey       backgroundcolor: 'rgba(76,175,80,0.2)',       bordercolor: 'rgba(76,175,80,1)',       pointbackgroundcolor: 'rgba(76,175,80,1)',       pointbordercolor: '#fff',       pointhoverbackgroundcolor: '#fff',       pointhoverbordercolor: 'rgba(76,175,80,1)'     },     { // grey       backgroundcolor: 'rgba(244,67,54,0.2)',       bordercolor: 'rgba(244,67,54,1)',       pointbackgroundcolor: 'rgba(244,67,54,1)',       pointbordercolor: '#fff',       pointhoverbackgroundcolor: '#fff',       pointhoverbordercolor: 'rgba(244,67,54,0.8)'     },     { // grey       backgroundcolor: 'rgba(103,58,183,0.2)',       bordercolor: 'rgba(103,58,183,1)',       pointbackgroundcolor: 'rgba(103,58,183,1)',       pointbordercolor: '#fff',       pointhoverbackgroundcolor: '#fff',       pointhoverbordercolor: 'rgba(103,58,183,0.8)'     },     { // grey       backgroundcolor: 'rgba(255,152,0,0.2)',       bordercolor: 'rgba(255,152,0,1)',       pointbackgroundcolor: 'rgba(255,152,0,1)',       pointbordercolor: '#fff',       pointhoverbackgroundcolor: '#fff',       pointhoverbordercolor: 'rgba(255,152,0,0.8)'     },     { // grey       backgroundcolor: 'rgba(96,125,139,0.2)',       bordercolor: 'rgba(96,125,139,1)',       pointbackgroundcolor: 'rgba(96,125,139,1)',       pointbordercolor: '#fff',       pointhoverbackgroundcolor: '#fff',       pointhoverbordercolor: 'rgba(96,125,139,0.8)'     }       ];    linechartlegend: boolean = true;   linecharttype: string = 'line';

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
