javascript - Ionic 3 - Native AppPrefences plugin_not_installed 错误
问题描述
这让我发疯了。所以我为此创建了一个专门的项目,这就是我所做的。
创建空白离子项目。这是控制台输出

将插件添加到我的 app.module
import { BrowserModule } from '@angular/platform-browser';
import { ErrorHandler, NgModule } from '@angular/core';
import { IonicApp, IonicErrorHandler, IonicModule } from 'ionic-angular';
import { SplashScreen } from '@ionic-native/splash-screen';
import { StatusBar } from '@ionic-native/status-bar';
import { MyApp } from './app.component';
import { HomePage } from '../pages/home/home';
import { AppPreferences } from '@ionic-native/app-preferences';
@NgModule({
declarations: [
MyApp,
HomePage
],
imports: [
BrowserModule,
IonicModule.forRoot(MyApp)
],
bootstrap: [IonicApp],
entryComponents: [
MyApp,
HomePage
],
providers: [
StatusBar,
SplashScreen,
AppPreferences,
{provide: ErrorHandler, useClass: IonicErrorHandler}
]
})
export class AppModule {}
然后这是我的 page.ts
import { Component } from '@angular/core';
import { NavController, Platform } from 'ionic-angular';
import { AppPreferences } from '@ionic-native/app-preferences';
@Component({
selector: 'page-home',
templateUrl: 'home.html'
})
export class HomePage {
constructor(public navCtrl: NavController, public appPreferences: AppPreferences, public platform: Platform) {}
checkPref(){
this.platform.ready().then((success) => {
this.appPreferences.show().then((success) => {
alert(success);
}, (fail) => {
alert(fail);
});
}, (fails) => {
console.log(fails);
});
}
}
page.html
<ion-content padding>
<button ion-button (click)="checkPref()">Check Plugin</button>
</ion-content>
当我点击它时,它显示“plugin_not_installed”
那么,我做错了什么?真的让我很沮丧。我已经弄清楚了我的应用程序上的所有内容,这是我需要的最后一点
**更新:我在 Ionic Dev App 的帮助下在我的手机(小米米 4i)上提供它
解决方案
cordova-plugin-app-preferences
不支持Ionic DevApp
。
因此,您需要将其构建为 apk 并作为真正的应用程序运行。
