As already mentioned in previous posts, in order to install Burps CA certificate, just go to the IP address Burp is listening on, followed by /cert, e.g. There you can download the cert and push it to your Android device. Usually you’ll get a binary certificate in DER format: cacert.crt.

Android won’t recognize this file as a cert. You’ll have to rename it to: cacert.der and push it to your device:

# mv cacert.crt cacert.der
# adb push cacert.der /mnt/sdcard

Afterwards you should be able to import your cert into your Android device.
