How to check which sim is installed as a standard sim in android programmatically

Question

I'm trying to check if my mobile device is dual sim, if sim1 is ready, if sim2 is ready, I ended up using java reflection, now I want to find out if sim1 isRoaming and if sim2 isRoaming, and if its dual sim, for which sim is installed by default. Is this possible with java reflection.

You can do something like this:

public int getDefaultSimmm(Context context) { Object tm = context.getSystemService(Context.TELEPHONY_SERVICE); Method method_getDefaultSim; int defaultSimm = -1; try { method_getDefaultSim = tm.getClass().getDeclaredMethod("getDefaultSim"); method_getDefaultSim.setAccessible(true); defaultSimm = (Integer) method_getDefaultSim.invoke(tm); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } Method method_getSmsDefaultSim; int smsDefaultSim = -1; try { method_getSmsDefaultSim = tm.getClass().getDeclaredMethod("getSmsDefaultSim"); smsDefaultSim = (Integer) method_getSmsDefaultSim.invoke(tm); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return smsDefaultSim; }
