Here is my StorageApplication Class
package com.example.testproject;
import android.app.Application;
public class StorageApplication extends Application {
private StorageService mStorageService;
public StorageApplication() {}
public StorageService getStorageService() {
if (mStorageService == null) {
mStorageService = new StorageService(this);
}
return mStorageService;
}
}
