When it comes to swift app development, making API calls from your Cordova mobile app can be a challenge, especially when dealing with security restrictions on Android Version 12. In this tutorial, we'll walk you through the process of resolving these issues and ensuring successful API calls from your Cordova app.

Prerequisites

Before diving into the solution, it's essential to have a solid understanding of the following:

  • Familiarity with Cordova and its plugins
  • Basic knowledge of JavaScript and jQuery
  • A Cordova project set up with a config.xml file
  • Android Version 12 or later installed on your device

Resolving API Call Issues on Android 12

To overcome the security restrictions on Android 12, you'll need to add the cordova-plugin-whitelist plugin back to your project and configure it correctly. Here's how:

Step-by-Step Guide

  1. Add the cordova-plugin-whitelist Plugin: Run the following command in your terminal: cordova plugin add cordova-plugin-whitelist
  2. Update the config.xml File:

`xml

`

  1. Configure the Whitelist Plugin: Create a new JavaScript file, e.g., whitelist.js, and add the following code:

`javascript

document.addEventListener('deviceready', function () {

var whitelist = new Whitelist();

whitelist.add('http:///');

whitelist.add('https:///');

whitelist.add('file:///');

}, false);

`

  1. Update Your JavaScript Code:

Ensure that you're making API calls from within a deviceready event listener. Update your AJAX code to use the whitelist plugin:

`javascript

try {

document.addEventListener('deviceready', function () {

$.ajax({

type: "POST",

url: localStorage.httptype + "://" + localStorage.serverip + "/FTServices/FTService.asmx/CheckServer",

data: "{chk: 'Hai'}",

contentType: "application/json; charset=utf-8",

dataType: "json",

jsonpCallback: "success",

success: function (result) {

// Handle success response

},

error: function (msg) {

// Handle error response

}

});

}, false);

} catch (error) {

console.error(error);

}

`

Best Practices

When developing your Cordova app, keep the following best practices in mind:

  • Always add the cordova-plugin-whitelist plugin to your project to ensure secure API calls.
  • Configure the whitelist plugin correctly by adding the necessary origins and intents.
  • Use the deviceready event listener to make API calls from within your JavaScript code.
  • Handle errors and exceptions properly to prevent app crashes.

Conclusion

By following this tutorial, you should be able to resolve the API call issue on Android Version 12 and make successful API calls from your Cordova app. Remember to add the cordova-plugin-whitelist plugin, configure it correctly, and use the deviceready event listener to make API calls.
