Can't install CA certificate on Android 11

Question

On preview version of Android 11 I got an error when trying to install CA certificate:

Intent intent = new Intent("android.credentials.INSTALL");
intent.putExtra("name", getCertName());
intent.putExtra("CERT", getCert());
startActivity(intent);

The error message is:

Can't install CA certificates

CA certificates can put your privacy at risk and must be installed in Settings.

I haven't found nothing on Android documentation about this change. Any ideas? Any workarounds (except to install it manually from settings)?

I have also face same issue.

Please follow below steps in android 11 or 11+.

In Android 11, to install a CA certificate, users need to manually:

1. Open Device settings
2. Go to 'Security'
3. Go to 'Encryption & Credentials'
4. Go to 'Install from storage' or 'Install a certificate' (depend on devices)
5. Select 'CA Certificate' from the list of types available
6. Accept a warning alert.
7. Browse to the certificate file on the device and open it
8. Confirm the certificate install
