Quick and dirty solution : put this into your launcher activity OR Application=>

try { getApplicationContext().getPackageManager().setComponentEnabledSetting(new ComponentName(“your.package.name”,“io.realm.internal.network.NetworkStateReceiver”), PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP); } catch (Exception e) {}

I’ll close this as a duplicate. We’ll keep track this in #3505.

We treat this as a critical issue. We’ll release 2.0.1 ASAP.
