It is difficult to root Android 4.4.3/4.5
|
In January this year, Chainfire, a well-known developer, said that the next version of Android may bring significant changes, one of which will involve root permissions. Google will eventually block the installation of root applications. Root applications are prohibited from decompressing files to the "/data" partition directory, and most root applications will write files to this directory. In fact, Google's big move is not aimed at root applications, but to improve the security of the Android system. Of course, there is no way. Based on the improvement of Android security, developers may modify it by themselves to ensure that root applications can run normally, such as extracting code and running from RAM or the root file system. The arrival of the above situation is only a matter of time, that is, when Android 4.4.3 or Android 4.5 arrives. Anfeng.com reported on May 20 that today, Chainfire said on its Google + that there are actually more changes in the new system, and believes that all these changes will make it more difficult to root the Android system. Because in addition to the previous situation, Google will also configure the new SELinux security policy. Basically, the old way of executing root will not work at all, but Chainfire has published its own root guide to show other developers how to avoid it. In addition, Chainfire said that Android Runtime is still the default setting in AOSP, but it is still impossible to apply it to firmware production. ART is undoubtedly a good thing, which can provide a faster experience for Android, with faster execution efficiency, higher efficiency and more power saving. However, when the application tries to call Java-based code such as "am" and "pm" in different contexts of the ART environment, due to the restrictions of SELinux and the immaturity of ART, it may cause the entire system to crash. Of course, even if ART is turned on by default, if you need to use Root applications in the future, you can switch back to Dalvik to solve the problem. In short, all the changes combined will make Root more difficult, and a large number of existing Roots will need to be updated, but it is still far from ending Root. Google's changes seem to frustrate many people who like Root, but remember that Google's current focus is to change Android's reputation as less secure than other operating systems, not to end Root. Developers' Root work continues, and the Android community has stated that as long as there is perseverance to overcome obstacles, it is not a problem. In this regard, Chainfire also revealed that the latest version of SuperSU (supporting the latest AOSP version) is ready and is waiting for the right time to be officially released. Finally, one more thing to note is that the AOSP culture continues, and it is not yet certain when the final version will be, and more Root work is also continuing.
