How to set default Server Url at login setting?

Shrikant  Borkar, hi!
This can be done simply via configuration file, which is is located here {your_custom_app_path}/config.app.json

Please study all available configuration by reading Javascript API Documentation part in docs that are shipped with SDK

Following configuration will set sugar server url and make if non-editable

"jsConfig": {
    "loginSettings": {
        /**
        * @property {boolean} editable - Flag indicating if the login settings is editable. If disabled, users wont be able to change sugar instance url,SSO settings. But would be able to edit SSL settings.
        */
        "editable": false,

        /**
         * @property {string} defaultServerUrl - Specifies the default server instance URL.
         * Used by native app to populate the server instance URL on the login view.
         */
        "defaultServerUrl": "http://localhost:8888/7_11/ent"
    }
}
