5Here's an example of an openjdk11 installation.
6
7```sh
8sudo apt update
9sudo apt install openjdk-11-jdk
10```
11
12The completion of the installation can be checked by the following command.
13
14```sh
15javac --version
16```
17
18The output looks like this:
19
20```sh
21javac 11.0.21
22```

24## d8
25
26The d8 tool is included as a standalone tool in the Android Studio build tool version 28.0.1 and higher. Therefore, you can get the d8 tool by downloading and installing the Android Studio tools.
27
281. Download Android Studio:
29
30```sh
31wget https://redirector.gvt1.com/edgedl/android/studio/ide-zips/2023.2.1.24/android-studio-2023.2.1.24-linux.tar.gz
32```
33
342. Decompress
35
36```sh
37tar -xzvf android-studio-2023.1.1.28-linux.tar.gz
38```
39
403. Launch Android Studio
41
42```sh
43cd android-studio/bin
44./studio.sh
45```
46
474. Configure a domestic mirror source (If you are prompted to download the Android SDK at this point)
48
49+ Go to the main Android Studio page and click on the lower button: `More Actions` -> `SDK Manager`。
50+ Find the left side: `Appearance & Behavior` -> `System Settings` -> `HTTP Proxy`。
51+ Select `Auto-detect proxy settings`，And then check `Automatic proxy configuration URL`。Fill in the mirror source address in the input box at the end, the optional URLs of the mirror source are as follows:
52
53```sh
54https://mirrors.aliyun.com/android.googlesource.com/
55
56https://mirrors.cloud.tencent.com/AndroidSDK/
57```
58
59Then restart Android Studio to download the Android SDK without any problems.
60
61Android SDK Path: `~/root/Android/Sdk/build-tools/`. The d8 executable program is located in the version number directory of the directory.
