Show HN: How I bypassed Exchange security on Android

I was messing around with AOSPA, wanted to figure out a way to bypass the encryption requirement to get exchange mails. Initially I thought I would have to modify the Email app or the part where the OS the administrative provisioning. But as it turns out all I had to do was comment out 8 lines of code

    private int getEncryptionStatus() {
        /*String status = SystemProperties.get("ro.crypto.state", "unsupported");
        if ("encrypted".equalsIgnoreCase(status)) {
            return DevicePolicyManager.ENCRYPTION_STATUS_ACTIVE;
        } else if ("unencrypted".equalsIgnoreCase(status)) {
            return DevicePolicyManager.ENCRYPTION_STATUS_INACTIVE;
        } else {
            return DevicePolicyManager.ENCRYPTION_STATUS_UNSUPPORTED;
        }*/
        return DevicePolicyManager.ENCRYPTION_STATUS_ACTIVE;
    }

So now the OS always thinks that its encrypted, and it doesn't ask for the encryption password on boot as that is done by a separate module.
