What? To over the wall? Please themselves on this issue, I am not responsible for the marketing VPN, is not responsible for solving their own problems brush Brush router over the wall, and is not responsible for all the problems related to over the wall, all get their own.
3, how to download?
What, will not download? I can not help you. But I'll give a hint. After entering the website, you will find a lot of content that can be downloaded. For example, first figure out the Android version you use, from Android 1.6 to Android 6.0, this can clear it.
After entering the corresponding version of the location and found several to be downloaded,
A, CDD, this compatibility is defined in the document, if you are a project manager or leader, you need to look at the product before confirming the need to take the Google CTS certification, this is of the basic requirements of the mobile phone of the machine, of course, Android TV, Android watches, Android tablet .... product definition requirements, technical staff and see just fine, no technical content, are defined.
b, then a problem is the mobile phone chip is ARM or X86, we must find out, download the corresponding version of the corresponding documents on two mobile phone chips, such as downloading the Android 5.1 Arm chip test kit is Android 5.1 R1 Compatibility Test Suite (CTS) -ARM and Android 5.1 R1 CTS Verifier-x86 package two, we are generally referred to as CTS and CTSV.
c, we also need to pay attention to a problem that is behind the R numbers are very important, because Google constantly changes, so from time to time the numbers will change back R, initially generally only change R1-R4, and later all the increased R7. So how do we choose the version R? The need and Google certification body, what version of the package corresponds to what version of GMS and CTS CTSV testing tools. GMS package we will get to speak.
d, then we also need to download something, and that is the media file CTS (CTS Media Files), this is a test case required resources file, put it plainly, is a bunch of different formats of video and audio files. The original media file on a CTS, now Google have changed, the media file to the three, what's the difference I found no actual use, it may be later versions of some additional documents, we did not use, if the fear of a problem, anyway, with the latest version of it.
4. What is the GMS package?
5. What is Google Authorized?
Android is open source, Android is free, however, it is important, however, GMS package is to make money.
Some people say that my own online download and install Google Market APK, not free? Yes, it is free, but for the average person GMS packet confidentiality, the company does not free, confidential except there is also a technical problem, GMS whole package can not be installed in case the machine is not prefabricated, because some code changes, even if some single APK can be installed, but also prone to some problems.
6, CTS and GMS, your concept clear?
• CTS package - testing tools, running on the computer
7, in fact, all three tools (some of the content we do not talk about, anyway, Google now fourth tool is not used, but you can also take a fourth authentication)
