Question

when i execute the code shown below

int random = (int)Math.ceil(Math.random()*100);
       Toast.makeText(getApplicationContext(), random, Toast.LENGTH_SHORT).show();  

i get this log

E/AndroidRuntime(  994): java.lang.RuntimeException: Unable to start activity Co
    mponentInfo{com.p/com.p.main}: android.content.res.Resources$NotFoundException:
    String resource ID #0x4b

Could you please tell me what is the error?

Answer 1

Use this:

Toast.makeText(getApplicationContext(), Integer.toString(random), Toast.LENGTH_SHORT).show();  

The Toast (or even TextViews) does not accept integers as input resources, you have to provide string resources.
