I'm not sure about the best way to resolve this problem, but here is what I did that worked fine for me.

I checked a boolean variable in the preferences, and if it returns false, I display the choosePrivateKeyAlias window. If it returns true, I know that I have permission to retrieve the certificate directly, so there's no need to display the popup.

boolean isGranted = prefs.getBoolean("MY_CERT", false);
if(!isGranted) {
        //Get cert and private key from internal android store
        KeyChainAliasCallback keyChainAliasCallback = new KeyChainAliasCallback() {
            @Override
            public void alias(@Nullable String s) {
                Log.d(TAG, "selected alias = " + s);
                SharedPreferences.Editor editor = getPreferences(MODE_PRIVATE).edit();
                editor.putBoolean("MY_CERT", true);
                editor.commit();
                retriveCertsTask.execute();
            }
        };
        KeyChain.choosePrivateKeyAlias(mActivity, keyChainAliasCallback, null, null, null, -1, CERT_ALIAS);
    } else {
        // Retrieve certs an private key
        retriveCertsTask.execute();
    }
}

Hope it helps...
