I am creating a database for an application in ionic 2, and it fails where I create it:
this.sqlite.create({
name: 'details.db',
location: 'default'
}).then((db: SQLiteObject) => {
//... }
Error:
OPEN database: details.db
Error: exec proxy not found for :: SQLitePlugin :: close
Error: exec proxy not found for :: SQLitePlugin :: open
OPEN database: details.db FAILED, aborting any pending transactions
Error: Could not open database

I have added the Cordova functionalities via ionic cordova platform add browser.
I run the app liko so:
ionic cordova run browser
Does it mean that this cordova functionality(create database) is not available in a browser?
You cannot open database via Cordova Web Browser.
What you can do is use the Emulator for Android provided by Visual Studio.
This way the database will be accessible.
It seems that you'll have to use a mock to be able to use browser environment with SQlite. I will try this, too: https://medium.com/#tintin301/ionic-sqlite-storage-setting-up-for-browser-development-and-testing-67c0f17fc7af
Some people warned about this so I would recommend this other approach:

I'm trying to use Google Cloud Text-to-Speech API in Meteor app, but get an error on the Meteor console and crash when trying to use the import function described in the instructions:
("Uncaught TypeError: Cannot convert undefined or null to object at Function.getPrototypeOf (<anonymous>)")
Here's what I've done (in app directory) before starting meteor:
meteor npm install google-tts-api
export GOOGLE_APPLICATION_CREDENTIALS="/data/authenticationinfo.json"
The problems are related to the inclusion of this line at the top of my js file:
import textToSpeech from '#google-cloud/text-to-speech';
This line cause the following Meteor startup error on the console:
"Unable to resolve some modules: "http2" in /app/node_modules/#grpc/grpc-js/build/src/channel.js (web.browser)
If you notice problems related to these missing modules, consider running:
meteor npm install --save meteor-node-stubs
Actually, I ran the above command, but it has no effect. When I run start the app, it crashes quickly with the error :
Uncaught TypeError: Cannot convert undefined or null to object

I have tested it on a barebones node app, and my Google authentication json file works fine, so that's definitely not the problem.
I realize there are are some Meteor packages for Google TTS, but they're really old and use Google Translate (which won't work for long) instead of the new cloud services.
So, it turns out the import has to happen on the server side, NOT the client side.
I am trying to login Facebook with Firebase. I have installed all the libraries required and completed the required configuration. Still, whenever I try to start my app it is giving me this error:

Able to solve this with below changes :
Just go to the below file in Ionic
plugins/cordova-universal-links-plugin/hooks/lib/android/manifestWriter.js
I fixed issue by changing pathToManifest as below:
var pathToManifest = path.join(cordovaContext.opts.projectRoot, 'platforms', 'android', 'cordovaLib', 'AndroidManifest.xml');
to
var pathToManifest = path.join(
cordovaContext.opts.projectRoot,
'platforms',
'android',
'app',
'src',
'main',
'AndroidManifest.xml');
For anyone that's looking into this these days, the actual fix for this was published by someone which you can pull in as a cordova plugin https://github.com/nordnet/cordova-universal-links-plugin/issues/133#issuecomment-369260863
#okaufmann you can use the changed version of the plugin. since it's not merged in the nordnet repository, you must remove the plugin and install again using:
cordova plugin add https://github.com/walteram/cordova-universal-links-plugin
After doing...
cordova plugin rm cordova-universal-links-plugin
cordova plugin add https://github.com/walteram/cordova-universal-links-plugin
.. my project was able to build successfully.
You need to update the AndroidManifest path in the plugin, which seems to be outdated. Check out this:
https://github.com/nordnet/cordova-universal-links-plugin/issues/146
I don’t know what is going on.
I reinstalled my Computer and updated Meteor. I had some permission problems in a earlier problem I could fix that tho. Meteor is normally running if I don't want to deploy it. Deploying used to work just fine btw.
mup.cmd deploy --settings settings.json

What does that mean? I couldn’t find any solution for my problem online. Do you know what is wrong?
This error can happen if your IP address cannot SSH. Make sure your IP
hasn't changed, or change your rules/IP in the security groups of the
service you are using.
There was another case of this recently here mup setup : Error: Timed out while waiting for handshake
But I don't think he sorted it out. He has also reported it on the mup issues list
You can also enable debugging and set mup to be verbose like this:
DEBUG=mup* mup <command> --verbose

I'm trying to learn to use react-native-sqlite-storage as described on this page here:
https://github.com/andpor/react-native-sqlite-storage
I am working on a windows machine trying to build an android app. I have the following code:
import SQLite from 'react-native-sqlite-storage';
function errorCB(err) {
console.log("SQL Error: " + err);
}
function successCB() {
console.log("SQL executed fine");
}
function openCB() {
console.log("Database OPENED");
}
var db = SQLite.openDatabase("test.db", "1.0", "Test Database", 200000, openCB, errorCB);
db.transaction((tx) => {
tx.executeSql('SELECT * FROM Employees a, Departments b WHERE a.department = b.department_id', [], (tx, results) => {
console.log("Query completed");
});
});
export default 1;
When I run this, I get the error
undefined is not an object (evaluating
'NativeModules["SQLite"][method]')
The error is happening on the line var db = SQLite.openDatabase("test.db", "1.0", "Test Database", 200000, openCB, errorCB);
I suspect the reason the error is happening is because SQLite expects the existence of a database before you can actually open it. However, I do not see any instructions in the link above on how to create a database with react-native-sqlite-storage, so I'm not sure if my assumption is correct. Additionally, I assume I'd need to have a table for Employees, but again, the link above didn't explicitly state examples on how to create one. SO I don't know if my assumption is correct.
So how do I get SQLite.openDatabase() command to work?
More information
I deleted my project. Then I tried to re-install everything again, this time closely following the installation instructions for sqlite storage for android as mentioned on the andpor's github instructions (ie, modifying gradle files, updating MainApplication class etc...). Once I did that, running the command react-native run-android from the CLI causes this build error:
ERROR EPERM: operation not permitted, lstat 'C:\Users\John
Lai\Projects\ReactNative\myapp\android\app\build\intermediates\exploded-aar\myapp\realm\unspecified\jars\classes.jar'
{"errno":-4048,"code":"EPERM","syscall":"lstat","path":"C:\Users\John
Lai\Projects\ReactNative\myapp\android\app\build\intermediates\exploded-aar\myapp\realm\unspecified\jars\classes.jar"}
Error: EPERM: operation not permitted, lstat 'C:\Users\John
Lai\Projects\ReactNative\myapp\android\app\build\intermediates\exploded-aar\myapp\realm\unspecified\jars\classes.jar'
at Error (native)
I tried running this command as a regular user and as an administrator, and still the same issue.
More Information 2
I deleted my project. Then I did npm install for all my projects. Then I tried the commands rnpm link and react-native link react-native-sqlite-storage, both of which gave this error:
ERR! It seems something went wrong while linking. Error: spawn UNKNOWN
Please file an issue here: https://github.com/rnpm/rnpm/issues
So now the project won't even build. Any ideas?
the problem is the library is not linked
to link they suggest two ways
with pod (advanced)
with rnpm link (easy) but this command is deprecated
so to link the library you should use the
react-native link react-native-sqlite-storage
this command is equal to rnpm link but not deprecated
if automatic build failing try with manual linking for iOS manually linking ios and android manually linking android
lstat command error is generating on windows due to permission issues or npm version issues.
You can do 2 things to pass this.
1.Open terminal in admin mode .
2.upgrade/degrade npm version
For plugin installation, configure manually
You need change MainApplication.java with:
import org.pgsqlite.SQLitePluginPackage;
and
in getPackages:
new SQLitePluginPackage()
I have a problem using Meteor in an Ionic2 project.
The project itself should run, as it is a clone of the Meteor-tutorial:
git clone https://github.com/Urigo/Ionic2CLI-Meteor-WhatsApp
When I start the Meteor server I get this
=> Started proxy.
server/publications.ts (24, 10): Property 'publishComposite' does not exist on type 'typeof Meteor'.
server/main.ts (14, 28): Property '_options' does not exist on type 'typeof Accounts'.
server/main.ts (51, 14): Property 'createUserWithPhone' does not exist on type 'typeof Accounts'.
=> Started MongoDB.
=> Started your app.
=> App running at: http://localhost:3000/
Then I start the ionic app with ionic serve and get this in the terminal
Running live reload server: http://localhost:35729
Watching: www/**/*, !www/lib/**/*, !www/**/*.map
√ Running dev server: http://localhost:8100
When I open the App I get this error in the browser's console:
Failed to load resource: the server responded with a status of 404 (Not Found) http://localhost:8100/sockjs/info?cb=_07sz35uj7
As I understand it means that it tries to grab data from meteor but couldn't reach it. When I open the URL in the browser manually and change the port to 3000 I get back a message from meteor.
I found two hints on Google:
1) start the ionic app without livereload
ionic serve --nolivereload
2) to set __meteor_runtime_config__ to the correct URL:PORT
But hint 1 doesn't work and for hint 2 I have no idea where to place it.
While writing this I found out, that in the file node_modules/meteor-client-side/meteor-runtime-config.js the correct port is defined by
__meteor_runtime_config__ = {};
__meteor_runtime_config__.DDP_DEFAULT_CONNECTION_URL = 'http://localhost:3000';
So it looks like hint 2 is also already done.
Why is it still trying to reach the meteor server on wrong port, or is there maybe another problem?
Ok, solved it on my own again.
I had to add those lines of code to the index.html file of my ionic2 project:
<script>
__meteor_runtime_config__ = {
DDP_DEFAULT_CONNECTION_URL: 'http://localhost:3000'
};
</script>
No idea, why the config in the node_modules/meteor-client-side/meteor-runtime-config.js file is ignored.
Edit: Looks like there was a bug that is fixed in version 1.3.5
