How Free Android VPNs Improve HTTP Security in App Development (2025)

The integration of a free Android VPN is essential for mobile application developers to protect sensitive communications by creating an encrypted tunnel between a user's device and a secure server. VPNs enhance HTTP security by encrypting data, making it unreadable to unauthorized entities. They use various encryption protocols such as OpenVPN, WireGuard, and IKEv2/IPSec to secure HTTP connections. Free Android VPNs are cost-effective for developers, allowing secure testing across regions, maintaining security during remote work, and protecting data integrity in app testing. While some free VPNs may compromise user privacy, reputable providers offer secure options with no-log policies. Five recommended free Android VPNs for developers in 2025 include X-VPN, Proton VPN Free, Windscribe, TunnelBear, and Hideme, each with specific features suited for secure app development. Best practices for using free VPNs include verifying VPN protocols, enabling a kill switch, regularly auditing security settings, and using dedicated VPN profiles for app testing.

Java for mobile app development: How to create Android apps in 2025 – London Business News

Java is a key programming language in mobile application development, particularly for Android, and is expected to remain relevant in 2025. It is officially supported in Android development, with a significant portion of Android applications built using Java. Java continues to be integrated into Android Studio and is favored for its comprehensive documentation, backward compatibility, and strong community support. Java's ecosystem is characterized by its mature tools and best practices, making it suitable for both simple and enterprise-level applications. Core components of Android apps built with Java include Activities, Services, Broadcast Receivers, and Content Providers. The development process involves setting up the environment with Android Studio, designing user interfaces with XML, implementing app logic in Java, testing the application, and deploying it via the Google Play Store. Best practices in 2025 include modular architecture, dependency management with libraries like Dagger and Hilt, asynchronous programming techniques, and the use of version control systems like Git. Java remains a viable option alongside Kotlin, especially for legacy codebases and its perceived accessibility for new programmers. Modern tools supporting Java development include Room for data storage, Retrofit for API calls, Glide for image loading, Firebase for cloud services, and Crashlytics for crash monitoring. Outsourcing Java development is a common strategy for companies looking to scale their mobile projects efficiently. Java continues to evolve, accommodating advancements in machine learning, IoT, and edge computing.

Critical PHP Vulnerabilities Expose Systems to SQL Injection & DoS Attacks

A security vulnerability identified as CVE-2025-1735 in the PHP pgsql extension has been disclosed, classified with moderate severity. It arises from inadequate error checking during input data escaping, specifically the failure to pass error parameters to the PQescapeStringConn() function and not verifying NULL values from PQescapeIdentifier(). This flaw affects PHP versions prior to 8.1.33, 8.2.29, 8.3.23, and 8.4.10, allowing potential SQL injection attacks and application crashes due to null pointer dereferences. The vulnerability is linked to a recent PostgreSQL vulnerability (CVE-2025-1094) related to invalid multibyte character handling. Developers are urged to upgrade to patched releases to mitigate risks.
