One: Environment preparation - install repo, git
1 : Repo is a tool developed based on git , which is convenient for git resource management, so we need to install git before installing repo
sudo apt-get install git
2 : Then create a new bin directory in the user's home directory
mkdir ~/ bin
3 : Add the bin directory to the system path , open ~/.bashrc , and add the following content
export PATH=~/bin:$PATH
Execute source .bashrc after saving
4 : Download repo
curl http://gerrit.googlesource.com/git-repo/repo > ~/bin/repo
Two: Environment preparation - configure git
git config --global user.name jiayou.gan
git config --global user.email [email protected]
Three: Environment preparation - configuration key
1: Generate ssh key file, execute ssh-keygen -t rsa -C "[email protected]";
2: Then you will be asked to enter the password twice, just press Enter, and the key fingerprint and key's randomart will appear at the end, indicating that the creation is successful.
3: At this time, execute la in the main directory, and you can see the generated .ssh directory
Four: Add the key to the SSH Public Kes corresponding to gerrit
•ssh$ cat id_rsa.pub
•ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDcC+GbffKN7ANMIL9f3FJpy+lCgovFhbfhh6Hy55nRkUu74pGatUYNVZZxa0gURbrpihAnu81DuOo+YSN/z0rwuQQLouXTmIcXcv538f2v04+Ww2BmR7DOS2xSQeTjwc0UGz31LAP/nHLJdQPds2FJgObcIqkf0gz9UHgQc4sV6J/pMdfVhIi1VZSSVw0T5+NtucBGYIUFG0nFwAnk5m5IvhK4FNaD9CTwCg8nE3PtwhAhDxXgtt2m1TbD9e8B6wkfXfyhRQ0WuPVd7SGhgjmBkXxNZn1b/+Eel+um5K9rMln2mvnhUd5p7mWtYxgfEo6SK0jSUOtCtJACYfTCixat [email protected]
Copy these contents and paste them into the corresponding SSH Public Keys on gerrit
Five: Code download
After the above configuration, you can download the code at this time
repo init -u http://username@XXX
If init reports an error as follows:
sign_and_send_pubkey: signing failed: agent refused operation
Permission denied (publickey).
Then execute the following command in the terminal and then re-init
eval "$(ssh-agent -s)"
ssh-add
repo sync -c -d --no-tags
Six: Code Compilation
source build/envsetup.sh
lunch and select the corresponding serial number according to the project
make -j32
Seven: Android common shortcut commands
• Check if the device is connected to the computer: adb devices
• Catch log : adb logcat (-b all) >log.txt
• Dynamic filter log : adb logcat (-b all)| grep " keyword " – i ( ignore case ) –-color ( highlight )
• Filter two or more keyword logs : adb logcat (-b all)| grep – iE " Keyword 1| Keyword 2"
• Find the name and location of the installation package based on keywords: adb shell pm list packages –f| grep “ keyword ”
• View the current app package name and activity name: adb shell dumpsys activity| grep Resumed
• Check phone resolution: adb shell wm size
Eight: It is recommended to look at the log tool
