Room database Export and Import Solution

Im facing same problem in one of my project, i spend two days to resolve this issue.

Solution

Don't create multiple instance for Room library. Multiple instance creating all the problems.

MyApplication

class MyApplication: Application() 
{

companion object {
    lateinit var mInstanceDB: AppDatabase
}

override fun onCreate() {
    super.onCreate()
    mInstanceDB = AppDatabase.getInstance(this)
}
}

AppDatabase

fun getInstance(context: Context): AppDatabase 
{

if (sInstance == null) {

    sInstance = Room.databaseBuilder(context.applicationContext,AppDatabase::class.java, "database").allowMainThreadQueries().build() 

            return sInstance!!
}
}

Now use this instance in any number of activity or fragment just like that

{
    var allcustomer = MyApplication.mInstanceDB.customerDao.getAll()
}

Export and Import use this library
