Android 9.0 native system is becoming more and more perfect： these apps have been eliminated.

Google has released a developer preview of Android P, the prototype of the latest generation of Android 9.0. If you are a user of Pixel devices, you can already experience the new system first. Compared with the previous Android system, Android P has obviously changed in function and mechanism.

Due to these changes, many good days of Android apps have come to an end, and they have to be laid off in the face of the new system of Android P. So what App will Android P eliminate? Let’s take stock.

Screenshot editing App

Whether it is Android or iOS, it has a screenshot function natively, and it does not need a third-party screenshot App like the early Saipan. However, if you use a native Android system, you often need to install a third-party screenshot App.

Why not, just because the system’s native screenshot function can’t edit the screenshot content after the screenshot, if you want to code some information of the screenshot, the native screenshot is powerless. Therefore, there is quite a market for third-party screenshot apps, but in Android P, they may be laid off.

In Android P, the system can edit screenshots natively.

In the first developer preview version of Android P, that is, the version of DP1, the system has added the native screenshot editing function. After the screenshot, you can do some simple daubing and cutting on the picture.

In fact, this function is not new. Screenshot editing has become a standard in many third-party Roms, but in Android P, it is finally going to be popularized in all Android systems, leaving the living space for third-party screenshot apps smaller and smaller.

Incoming call firewall App

In the era of the popularity of smart phones, apps have stolen more and more privacy, so how to prevent harassment is also a technical activity. Many people will isolate harassing calls by installing an App such as an incoming call firewall, and the effect is really good. However, in Android P, these incoming firewall apps may encounter challenges, because Google intends to do this function in person.

In the open source code of Android P, the developers found the related content about the incoming call firewall, and this part of the code was submitted by Sony to the Android open source project. According to the relevant code, Android P can intercept numbers that are not in the contact list, undisclosed numbers, numbers that lack information, etc. Although the function is relatively elementary, it is still a practical improvement.

Android P will have a stronger incoming call firewall.

So will the incoming call firewall App be replaced? Or will not be completely laid off. It seems that this call interception function of Android P can be turned on by the operator, and its functions are not comprehensive. For example, it seems that it is impossible to intercept calls through the cloud database.

In fact, many third-party Roms have added the function of call firewall to Android, and Android P natively adds some basic call interception settings. If you want to achieve a better effect of Approaching third-party Roms, I’m afraid the call firewall app is still necessary.

Bluetooth mouse and keyboard simulation App

Android is very playable. For example, Android can simulate the mouse and keyboard of a PC through a third-party App. Generally speaking, to realize this kind of function, you need to take the remote desktop protocol and connect through the Internet or WiFi. However, in Android P, the system’s own function of simulating mouse and keyboard goes further. The Android P system itself can connect to the computer through Bluetooth, making the mobile phone become the Bluetooth mouse and keyboard of the computer, which is very convenient.

At present, some apps on Android can make mobile phones act as Bluetooth mouse keyboards.

In Android P, the system should have related functions natively.

There is no doubt that this is a very practical function. People can’t find a Bluetooth mouse and keyboard anytime and anywhere. When you suddenly want to remotely control the HTPC in the living room, or you can’t find a remote controller to demonstrate PPT for a while, Android P can make your mobile phone come in handy.

System tools such as refrigerator /Xposed.

The reason why the App mentioned above will be laid off is mainly because Android P provides similar functions. However, in addition to new functions, the system mechanism of Android P has also changed, which leads to some previously available apps not running in the new system, thus facing elimination.

In Android P, Google has greatly restricted the use of unofficial APIs. Google will lock the APIs that the App can access, and some APIs of the system will no longer be provided for the App to access, and it is difficult for the App to use unauthenticated APIs.

What will be the result? On the one hand, it will directly lead to the failure of the push and sharing functions of many apps. Some apps can achieve the push function because they use some third-party push platforms and need to access relevant API；; On the other hand, the black technology App that many players like to see and hear can’t be used.

Unofficial API may not be available in Android 9.0.

Many Android apps with high playability will use some APIs that are not included in the official SDK. For example, Xposed and refrigerator, etc., through some hooks, you can achieve functions that ordinary apps can’t do.

However, in Android P, Google will restrict the use of non-SDK methods and fields, and developers will not be able to access them — — Whether through direct call, reflection or JNI. If you try, you will receive error prompts such as NoSuchFieldException or NoSuchMethodException. Therefore, many apps that players like to see and hear are basically abolished and have to step down in the new system.

Old applications/using old SDK applications

Some friends may not agree that these system tools have been eliminated by Android P. After all, these tools are generally unpopular and only players will care. However, apps that are forced to be laid off are actually not limited to these niche tools. In Android P, apps that are frequently contacted by the public may also be on the verge of elimination.

A large number of domestic apps still use the old SDK and may face elimination.

In the new system, Android P has made strict restrictions on the application of the old Target API. Google added a new regulation MIN_SUPPORTED_TARGET_SDK_INT to the SDK. If the SDK version of the App is lower than v17, then the App will not be compatible with Android P. This means that Android 4.1, including the previous version of the App, will be eliminated in Android P.

Now that the first developer preview version of Android P has been released, developers have also tested it. The test results are as expected, and the old version of the App really can’t run. In Android P, although the old version of the App can still be installed, when it is opened, the system will warn that the App is incompatible and needs to be upgraded. At present, many domestic apps still use the old SDK. I am afraid that in the era of Android P, these old applications will become history.

summary

In fact, each generation of Android will add more functions close to practical applications, and it will also set up some unprecedented restrictions. These measures will inevitably squeeze the living space of some apps.

However, although each generation of Android system will bring challenges to old apps, it will often bring many new opportunities, such as the Internet of Things and ARCore, which are the mainstay of Android in the past two years, which can make people see many possibilities. Android 9.0 is undoubtedly a dramatic version. I hope that both Google and App developers can bring users a better experience in this generation of Android.
