I'm accessing a Pojo class having static method for returning value. When I access this static method in my Splash Screen class(Launcher page), I get a NoClassDefFoundError for that Pojo class. How to avoid this exception without making the method non-static?

Pojo class

package shared_pref;

Splash Screen class

public class SplashActivity extends AppCompatActivity {


    private String user_id = "";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_splash);

        // Here I get NoClassDefFoundError
        user_id = SharedStorage.getValue(getApplicationContext(),"UserId");



        new Handler().postDelayed(new Runnable() {

                }
            }
        }, 3000);

This is caused when there is a class file that your code depends on and it is present at compile time but not found at runtime. Look for differences in your build time and runtime classpaths.

Same error happens if I use an object. I'm trying to keep the pojo under same package name as declared in Manifest. @Rushi – Somnath Pal Nov 28 '16 at 11:39
