Android ART: The runtime environment of Android

Since the update to Android 5 - also called Lollipop - the operating system runs under a new Java runtime environment. This was previously Dalvik and has been completely replaced by ART (Android Runtime) since Android 5.0.

While you as a user primarily benefit from better performance, Android ART brings many innovations, especially for app developers. The runtime environment is a fundamental element for programming from the system as well as the applications on it. With the introduction of ART came several innovations for the development of apps. Apps that were still developed on Dalvik, however, are and were usually also compatible with the new execution environment. However, some techniques have changed completely.In general, Android ART introduced many features that are supposed to simplify the development of apps. Problem determination is also supported in the runtime environment and made more comprehensible. For Google's Android operating system, there are of course also advantages for users.

Some advantages of Android ART over Dalvik

Since Android 5, the Java runtime environment ART is used, which improves the performance of Android devices.

• Some codes in programming language are converted directly into binary codes, which ensures the faster launching of applications.
• The faster opening puts less load on the processor. This not only saves the processor, but also your battery life.
• For the codes can be converted directly, more memory is required in part. Accordingly, the larger files also take longer to download.

On the official website of Android ART you will find not only a detailed overview, but also many tips and tricks if you want to develop an app.
