Question

At first start, my app set preferences to “true” about checkboxpreference. Now I need to set this value (android:enabled=”true”) or false programmatically. Any idea?

protected void checkLicense(){
        PackageManager manager = getPackageManager();
        if (manager.checkSignatures("core.package.name", "key.package.name")
            == PackageManager.SIGNATURE_MATCH) {
            //full version
            isEnabled = true;
            Toast.makeText(this, "pro", Toast.LENGTH_LONG).show();
        }
        else {
            Toast.makeText(this, "free", Toast.LENGTH_LONG).show();
            isEnabled = false;




<CheckBoxPreference
                        android:enabled="true"
                        android:title="Now"
                        android:defaultValue="false"
                        android:key="keep" />
