I'm assuming your getSMS()
is not returning anything. You can check this by adding some debugging code after this line:
List<String> msgList = getSMS();
Something like
Log.d("yourTag","number of items: ".msgList->size());
It seems that it doesn't return anything. You might start by debugging that particular function: are there any exceptions caught? add some logging to see that. Maybe you didn't add the correct line in your manifest
<uses-permission android:name="android.permission.READ_SMS"/>
Or something else goes wrong in that function. Did you write it yourself, or was it a copy?
remove c.close()
in your getSMS method.
the problem is line " ArrayAdapter adapter = new ArrayAdapter(this,R.layout.main, msgList); "
argument R.layout.main is false , it's layout item custom by you Or android built example like android.R.layout.simple_list_item_1
=> change R.layout.main - > android.R.layout.simple_list_item_1 . succsess 100 %
