Android_Cert_Installer.sh

Author: Osezua Purpose: Automatically installs Certificates in DER formats in android studio emulators running android open source

🚀 Usage

1. Clone Repo

git clone https://github.com/0s3zu4/android-lab-scripts.git

2. Make the script executable

chmod +x Android_Cert_Installer.sh

2. Run the script

./Android_Cert_Installer.sh

You will be prompted to:

• Select your emulator (if none is running)
• Install a certificate file into the emulator

---

📝 Requirements

• AVD with writable system image (-writable-system)
• adb, openssl, and emulator CLI tools installed
• Android emulator image with API level 24+ (tested with API 28)
• a proxy certificate in .der format in the same directory (eg. burpcert.der)

📌 Notes

• Magisk patching is a manual step — wait for full boot and complete all prompts.
• Certificate must be in DER format.
• You’ll be prompted to select the .der file if multiple are present.
• This modifies /system/etc/security/cacerts inside the emulator.
