我正在运行Ionic 2 RC4,当我运行ionic run android时,该应用程序可以运行,但是设备准备就绪会在15-18秒后触发。我试图在设备ionic运行android --prod上运行,但是它在chrome inspector中显示未安装sqlite插件,这是不正确的。如果我转到另一个页面并返回,它将显示来自SQLite的数据。
constructor is called

main.js:4 Native: deviceready did not fire within 2000ms. This can happen when plugins are in an inconsistent state. Try removing plugins from plugins/ and reinstalling them.

我试图将设备放置在几个不同的位置,并且我也登录了许多位置。最后一个控制台日志称为构造函数
constructor(public timeSince: TimeSinceService,
public platform: Platform) {
console.log("constructor is called"); //called
if(!this.isOpen){
this.db = new SQLite();
this.db.openDatabase({name: "aces.db", location: "default"}).then(() => {
console.log("open Database"); // not called
this.db.executeSql('PRAGMA user_version = 0', []).then(()=>console.log("yesss")) // not called
this.db.executeSql('PRAGMA user_version', []).then(data => {
if(data.rows.item(0).user_version !== current_version){
console.log("versions do not match");
}
})
this.db.executeSql('PRAGMA foreign_keys = ON', []).then(()=>{
let query_matches = 'CREATE TABLE IF NOT EXISTS matches '+
'(id INTEGER PRIMARY KEY AUTOINCREMENT,'+
...';
let query_comments = 'CREATE TABLE IF NOT EXISTS comments '+
'(id INTEGER PRIMARY KEY AUTOINCREMENT, '+
...';
let query_points = 'CREATE TABLE IF NOT EXISTS undo'+
'(point_id INTEGER PRIMARY KEY AUTOINCREMENT,'+
...';
let query_organizations = 'CREATE TABLE IF NOT EXISTS organizations '...
let query_users = 'CREATE TABLE IF NOT EXISTS users '+
'(id INTEGER PRIMARY KEY AUTOINCREMENT,'+
...';
Promise.all([
this.db.executeSql(query_matches, {}).then(() => {
console.log("table created");
}, (err) => console.error('Unable to execute sql for matches: ', err)),
this.db.executeSql(query_comments, {}).then(() => {
console.log("comment table created");
}, (err) => console.error('Unable to execute sql for create comment table: ', err)),
this.db.executeSql(query_organizations, {}).then(() => {
console.log("table organizations created");
}, (err) => console.error('Unable to execute sql: ', err)),
this.db.executeSql(query_points, {}).then(() => {
console.log("undo table created");
}, (err) => console.error('Unable to execute sql for undo table: ', err)),
this.db.executeSql(query_users, {}).then(() => {
console.log("table users created");
}, (err) => console.error('Unable to execute sql: ', err))
]).then(()=> {
console.log("called promise all");
this.isOpen = true
})
})
}, (error) => console.log("ERROR couldn't open database from sqlite service: ", error));
}
}
最佳答案
如果有人遇到相同的问题,请回答我自己的问题。
我必须在app.component.ts中的DeviceReady中调用rootPage。我希望它对某人有帮助。
