Complete Guide

Before moving on to the vital topic, let’s have a strong insight into the Android package. A package could be a directory that houses our ASCII text file in general. Typically, your application will be uniquely identified by a directory structure, such as, which is kept in /data/app/com/com/. is a package for Android. This indicates that it has the Android operating system preinstalled. The acronym CTS stands for the compatibility test suite. Every Android app has a package that contains the necessary files, such as com.sec.pdf and source code. Each package has a name that is specific to it. As a result, the system can easily track the package and learn whenever a new app is released. Apps for Android are known to include valuable files and source code. The software can be recognized thanks to its distinctive name. When the different apps are identified, conflicts are avoided.

You’ve come to the right spot if you are looking for information on what is and how it functions. However, occasionally it can result in the error “Com.Android.cts.priv.ctsshim Has Stopped“. I also had the unfortunate experience of going through this. If you experience the same problem, the solutions are covered in the sections below. We have covered everything you need to know about it in this article, along with a decision regarding whether it can be erased.

If you want to know and find out what is and how it works in Android, then undoubtedly you have come to the right place. Here, on Gossipfunda, we will tell you all about and we will also be answering every possible question related to the same. The is nothing but a package that comes without saying, with your Android operating system. The various functions and workings of the are co-related with different functions of your respective Android device. Today, we will find out what exactly is Let us start!

First, one should be well-versed with the definition and usage of an Android package. An Android package is basically a directory or a place where our source code is located or stored. This directory has the ability to identify your application such as and store it under /data/app/com/com/.

What exactly is Com Android Cts Priv Ctsshim?

It is crucial to note that the app is considered a free test suit intended for makers of Android devices. During the system’s development, the com.Android.cts.priv.ctsshim aids in identifying compatibility issues with the Android operating system.

Now that you know what is and why it bears that name. You should be aware that there will exist two packages: com.Android.cts.priv.cuss him and com.Android.cts.ctsshim; the latter is a privileged system app located in the system partition’s private-app directory. The claim that the term “priv” used here stands for “private” on some websites is untrue.

When we talk about, then we should keep in mind that it is basically a package that is related with the Android Operating system. There are namely two packages that can be found by a user in the list of applications in their system. ‘CTS’ is nothing but a short form for ‘Compatibility Test Suite’ and ‘priv’ is for ‘private’. The foremost package that you may find in your system applications is privately used and has limited access which is also highly encrypted. The second package is used publicly and is called 

The Compatibility Test Suite is a very helpful tool, especially for developers. There are a number of issues that are faced by users all over the world, when it comes to the applications of Android. Some of the issues that are quite common among the masses are incompatibility of the application with the device, the applications are designed in accordance with the latest technological advancements but there are times when the new technological updates are not supported well by the old versions, applications might not work as efficiently as promised etc. 

Where to find CTS?

You can easily locate the CTS on your system. It is used to verify various upgrade scenarios on your device. Vendors find running a test scan very helpful as it helps them to ensure that their hardware is compatible enough with the current Android OS. When we talk about CTS, we should be aware of its parts. CTS consists of two parts, the first one is designed to run on the development computer such as Mac or 64-bit Linux and the other part is present as a file on the system, by default. Thus, is pre-installed. We should know that the applications that come pre-installed with your device should not be hampered. Doing so, would disrupt the normal working of your device and hence mess with the working speed, compatibility, performance etc.

What is the Application of Com.Android.CTS.Priv.CtsShim?

CTS, or more specifically, has been identified (Compatibility Test Suite). As a result, it functions much like a developer tool to identify and fix compatibility issues with Android applications. There are two pieces to it, one operating on a PC and the other on an Android device.

Additionally, CTS functions as a program installed on a device or system partition to test particular upgrade scenarios. It indicates the specific APK used to upgrade it and contains code. It’s a crucial component of Google’s SafetyNet API. You can be confident that by doing this your phone is authentic and that no crucial system settings have been changed. If we created our Android application, the term “” would automatically be present. If you’re trying to run a program, delete the road and execute it in your Android studio; it will function properly.

What is used for?

Now that we are aware of what is about, we might as well look at its uses. Compatibility Test Suite is basically a tool that is helpful for the developers which assists them to find solutions regarding the compatibility issues between the device and applications, in different versions of Android. This helps the users to ensure that the hardware used by users is compatible with the current Android OS. It mainly consists of two parts:-

  1. The first part of the CTS is designed for the PC, specifically Mac or Linux
  2. The second part is the pre-installed part i.e. it automatically comes inbuilt in your device.

CTS is a complete package that is found in your device. It consists of a code which is designed to specify the singular APK which is used to further upgrade it. We should know that it is a crucial component of SafetyNet. SafetyNet is an API by Google. Its main job is to ensure that your phone or any other device is original and is disrupted with any unwanted system parameters or any updates that are not needed at the moment. If someone wants to build an Android application of their own, then ‘’ will be included in it by default. So, if you wish to run a program, then you need to first remove ‘’ and then proceed in your Android studio. Following these steps correctly, you will face no issues in the performance of your application.

An important thing to note is that if the user owns root rights, then that means that they can rightfully remove the application from its source. Now, a question arises that why would anyone want to remove the application from its source? Well, a lot of factors might lead to such a decision such as slow performance of the device, fast draining of the battery, etc. If any of these things are happening to your device, then it is natural for you to want the app to be removed. But if any of these problems are not being faced by you, then please do not remove this application. As already explained in the article, removing a pre-installed application can cause problems with the device’s performance.

The Latest CTS version

‘CTS is a free suite of compatibility tests’, is stated by the Mi community. The CTS runs on the PC and needs a connected device in order to start performing its tasks. CTS is a bunch of unit tests combined together which are designed to inculcate into the daily work of engineers and other business/organizations. Identifying incompatibility issues also benefits the users in other ways such as ensuring software compatibility which in turn ensures a smooth development process. 

You can visit the android source site in order to download, where you can get the CTS version for your current android and also the old one if needed. You can download the latest CTS version for your Android on the website of

Steps to set up a proper environment and Android device for CTS?

You should be well aware of being able to set up a suitable environment and a suitable device for the CTS to perform its tasks efficiently. The three main things that one should keep in mind while setting up the CTS are:-

  1. The Physical environment.
  2. The Android device used by you, on which you will carry out the test.
  3. Your desktop machine (64-bit Linux or Mac)

The Physical Environment

The physical environment further consists of a number of sub-parts. They are listed as follows:-

Bluetooth LE Beacons

Firstly, we should know that the device that is put under test is known as DUT (Device Under Test) as we will be using this abbreviation ahead. The DUT supports bluetooth and the user should keep at least three Bluetooth LE Beacons within a range of 5 metres from the Device Under Test. This is for when there is a need for Bluetooth Testing,

Please note that the beacons do not have any requirement of wanting to be reconfigured in any way. They are of various types such as Eddystone, iBeacon, etc. Also, devices stimulating BLE Beacons can also be used for this same purpose.


When you are running Camera CTS, you should make sure that you are using normal lighting conditions. Various test pattern checks such as a checkerbord pattern can be used as well. The minimum focus should be set well on the device that is under test. You have to place the pattern chart according to the focus set. Doing so, will ensure that the pattern is placed at an adequate distance from the lens.

You need to point the camera in such a way such that the lighting is sufficient. This in turn ensures that the sensors would meet their desired FPS. It is recommended to do this for all the sensors and not just for one sensor.

If your device under test supports external cameras, then you need to plug it in when you start to run the CTS. USB webcams or any other webcams can be considered as a source of external cameras. You should follow these steps with caution as failing to do so will lead to a failure in your test being performed.


GPS stands for Global Positioning System and GNSS stands for Global Navigation Satellite System. If your device under test supports the GPS or GNSS, then the device should be provided with an appropriate signal for the same. The GPS should have ICD GLS-200C, in order for the signal to reach successfully. You can place your device under test outdoors or somewhere where there is a better reception in order for signals to transfer without any issue. 

Wi-Fi and IPv6

The device under test needs to be treated as a solo client, which means a configuration wherein the device cannot display messages on any sub-networks. There is a requirement of a Wi-Fi connection supporting the iPv6 and an internet connection.

This can be easily done with the help of a Wi-Fi AP configuration. There is one more solution to this i.e. you can run your device under test on an isolated subnetwork where no other device is connected. 

When you do not have access to some IPv6 carrier network or VPN, you can use an IPv6 tunnel or Wi-Fi AP also!

Android Device Setup

Screen and Storage

You need to connect your device to a screen if it does not have an embedded screen already. This can be done with the help of LCD displays. In the memory card slot of your device, plug in an empty SD card. You must insert an empty SD card as during a CTS test, there are high chances that your existing data might get deleted. This can make you lose your sensitive and important data so in order to make sure this doesn’t happen, always use an empty SD card.

Desktop Setup

You should know that CTS does not support Windows OS. Only a 64-bit Linux, or a Mac device can be used.


The latest versions of AD and AAPT should be installed by you. Then, you need to add their locations to the path of your desktop. ADB stands for Android Debug Bridge and AAPT stands for Android Asset Packaging Tool. You may also download the Android SDK Tools, which would come into use when you need to install the Android Debug Bridge. You need to then open it, and follow the instructions as directed. 

JDK for Ubuntu

The latest and most suitable version of JDK i.e. Java Development Kit should be installed on your device. 

  1. Install the OpenJDK11 for Android 11.
  2. Install OpenJDK9 for Android 9(P) and Android 10(Q).
  3. Install OpenJDK8 for Android 7 and Oreo.

How to run the Android CTS?

You can follow the steps given below in order to successfully run the Android CTS on your device.

  1. Go to the home dashboard of your device under test and set it to the home screen, before the start of the test. 
  2. When the DUT is running, it should not be used for any other purpose. The reason 
  3. for this is that the test runs smoothly if it gets an adequate amount of memory and hence we should take care of that. 
  4. The cameras that have been already set towards lightning should be checked and adjusted if required. 
  5. You should avoid pressing any keys, while the CTS test is running. There are other running tests too and they should in any way not interfere with the CTS test.
  6. Now, you need to locate the folder where the CTS package was unzipped and then launch the CTS console by running the cts-tradefed script. 
  7. Now, start the default test plan which in-turn starts all the required CTS tests.
