Answer 1

Use this code to test connectivity:

 final ConnectivityManager conMgr = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); final NetworkInfo activeNetwork = conMgr.getActiveNetworkInfo(); if (activeNetwork != null && activeNetwork.isConnected()) { //being here means you are connected } else { //being here means you are not connected } 

And also include this in your manifest:

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission> 

Thus, you can set the boolean value to true or false depending on the connectivity and use it to determine whether to open the menu or not.

Try this code to check internet connection .

 public boolean isOnline() { ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo netInfo = cm.getActiveNetworkInfo(); if (netInfo != null && netInfo.isConnectedOrConnecting()) { return true; } // your code here(Toast) return false; } 

And include this permission in your manifest:

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission> 

and call this method before setContentView .

 /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); isOnline(); setContentView(R.layout.main);
