The Simulator is responding very slow on my MAC book while running apps. The issue here I found is somehow slow animations are enabled in the simulator. The solution for this is press "Command+T" on the simulator. It may be simple and funny, but it worked for me. Try yourself :).

Working with Oracle MCS Database Management API
In Oracle Mobile Cloud Service (MCS) "Database Management API" is another API in addition to "Database Access API" which lets you view table metadata, and create, drop, and re-create tables. This post is not to explain about the API but to see how to access it from outside. Please click here to know more about the API.
The good part of this API is, you can access this API from outside of MCS using any rest client tool.
In this example, I am using Postman.
To access the “Database Management API” from outside, you need to pass MCS login credentials instead of mobile backend authentication details along with mobile backend id to every API.
Below is a screenshot for your reference where it is fetching meta data of my table “MY_CUSTOMER”. Note that the table name here is case sensitive.
Below is the full output of the above GET operation to fetch meta data of a table "MY_CUSTOMER".
{
"name": "MY_CUSTOMER",
"primaryKeys": [
"id"
],
"requiredColumns": [
"id"
],
"columns": [
{
"name": "id",
"type": "decimal"
},
{
"name": "vehiclenum",
"size": 6,
"type": "string"
},
{
"name": "customermobile",
"size": 14,
"type": "string"
},
{
"name": "customernum",
"size": 7,
"type": "integer"
},
{
"name": "customername",
"size": 8,
"type": "string"
},
{
"name": "vehicleserial",
"size": 9,
"type": "string"
},
{
"name": "createdBy",
"size": 80,
"type": "string"
},
{
"name": "createdOn",
"type": "dateTime"
},
{
"name": "modifiedBy",
"size": 80,
"type": "string"
},
{
"name": "modifiedOn",
"type": "dateTime"
}
]
}

Passwordless Login
Many apps are required to register. As per a survey, many users are leaving apps just because they don’t remember passwords. Many users don’t enter the app as they don’t like the long registration process. Even If the app provides social login (like Facebook login), few users do not want to share their social account details with the apps.
Another survey tells that users are interested to register using their phone numbers as smart phone users are growing. So, the best way to get more users to any app is to provide sign up using either
- Phone number
- Or Email
- Or Social logins like Facebook
Social login is a common implementation, many developers may already know how to implement. But if you want to authenticate using either of the first two methods, then Facebook is providing an SDK called Account Kit to register using just phone number or email.
