Apps using ReLinker

ReLinker is a powerful and robust Android library designed to solve one of the most common issues faced by developers working with native libraries: the unreliable loading of .so files on certain devices. This open-source SDK, developed by KeepSafe, addresses the limitations of Android's default native library loading process, providing a more reliable and efficient solution for app developers. ReLinker is particularly useful for applications that rely heavily on native code and need to ensure smooth operation across a wide range of Android devices and versions. The primary purpose of ReLinker is to mitigate the "UnsatisfiedLinkError" that often occurs when an app attempts to load native libraries on some Android devices. This error can lead to app crashes and poor user experience, especially on devices with custom ROMs or those running older versions of Android. ReLinker works by implementing a more robust library loading mechanism that can overcome these issues, ensuring that native libraries are loaded correctly and consistently across different devices and Android versions. One of the key features of ReLinker is its ability to handle library loading failures gracefully. When the standard Android library loader fails, ReLinker steps in and attempts to load the library using alternative methods. This includes extracting the library from the APK if necessary and loading it from a custom location. This approach significantly reduces the likelihood of library loading failures and improves the overall stability of apps that rely on native code. ReLinker also offers advanced features such as asynchronous library loading, which can help improve app startup times by moving the library loading process off the main thread. This is particularly beneficial for apps with multiple or large native libraries, as it prevents the UI from freezing during the loading process. Additionally, ReLinker provides detailed logging and debugging options, making it easier for developers to troubleshoot any issues that may arise during the library loading process. Implementing ReLinker in an Android project is straightforward, thanks to its well-documented API and integration with popular build tools like Gradle. Developers can easily add ReLinker to their projects using a simple dependency declaration, and then use its API to load native libraries in their code. The library is designed to be a drop-in replacement for System.loadLibrary(), requiring minimal changes to existing codebases. ReLinker is actively maintained and regularly updated to ensure compatibility with the latest Android versions and devices. Its open-source nature allows for community contributions and rapid bug fixes, making it a reliable choice for developers looking to enhance the stability of their native library loading process. The library has gained popularity among Android developers working on complex apps that require native code, such as games, multimedia applications, and performance-critical tools. In conclusion, ReLinker is an essential tool for Android developers working with native libraries, offering a robust solution to common library loading issues. By implementing ReLinker, developers can significantly improve the stability and reliability of their apps across a wide range of Android devices, ultimately leading to a better user experience and reduced crash rates. Its ease of use, advanced features, and active maintenance make ReLinker a valuable addition to any Android project that relies on native code.
