I need your help. I have to make an Android app in a company and have some problems to run and configure Android Studio. The network uses a proxy (from Zscaler) and I can't synchronize project from Gradle scripts.
The administrator have given to me the proxy address and on check connection settings, connection is successful with the 2 download domains from the build.gradle scripts. But it doesn't work on Gradle sync.
THE FOLLOWING ERRORS:
With normal case on build.gradle:
- Could not GET: "https://dl.google.com.dl/android/maven2/"
- Could not GET: "https://jcenter.bintray.com/
With http on maven blocks: Could not GET (From jcenter binary with
http)
Unable to find valid certification path.
I have also import manually certificates from the company, but it doesn't work.
You can look on images to show you my configuration I have tried, and it doesn't work.

Help me please, it's extremely important. I can't do the objectives otherwise.
You need to inject your companies proxy cert into the cacerts keystore of the java attempting to download files. This may be either the OpenJDK version that is supplied with your Android Studio or the one being used by the operating system.
Keytool is located in /jre/bin
The "cacerts" file is located in /jre/lib/security
Run the following
keytool -importcert -file <path to cert> -keystore <path to cacerts>
-alias <anything>
You'll be prompted for the password, default is "changeit"
You'll then be asked if you trust the cert, type yes.
The official solution, with keytool (3 lines to execute at least):
On command line (cmd, terminal), open the directory /jre/bin, commands to write:
keytool -import -alias <alias> -file <certificate_path .crt or .cer> -keystore ../jre/lib/security/cacerts
Each Java part (JRE) must to have certificates added with keytool (Java, Android Studio,...), the 2 lines must to be executed:
keytool -import -alias <alias> -keystore <path_to>\system\tasks\cacerts -file <certificate_path .crt or .cer>
keytool -importkeystore -srckeystore <path_to>\system\tasks\cacerts -destkeystore "<path_to>\Java\<jre_path_name>\lib\security\cacerts"
Reboot the system after.
