android - NoClassDefError while getting EntityManagerFactory instance -


I am creating Android apps with the API engine backend. But to insert the unit to the datastore, I'm unable to get unit mangerfayet (EMF) as an example, it throws noClassDefFound error. I have tried all the solutions suggested earlier in the questions.

Eclipse version: 4.2.0 Using Jre7 and using apengine-java-sdk-1.8.8

Emf class generated by Google plugin: 

  import javax.preistence.EntityManagerFactory; Import javax.preistence.Persistence; Public Final Category EMF {Private Stable Last EntityManagerFactory emfInstance = Perseverence.createEntityManagerFactory ("Transaction-Optional"); Private EMF () {} Public Fixed EntityManagerFactory get () {emfInstance return; }}

persistence.xml: 

  & lt ;? XML version = "1.0" encoding = "UTF-8"? & Gt; & Lt; Persistence xmlns = "http://java.sun.com/xml/ns/preistence" xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance" xsi: schema location = "http: / /java.sun.com/xml/ns/pressistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd "version =" 1.0 "& gt; & Lt; Firmness unit name = "transaction-optional" & gt; & Lt; Provider & gt; Org.datanucleus.api.jpa.PersistenceProviderImpl & lt; / Provider & gt; & Lt; Properties & gt; & Lt; Property Name = "Datanualysis. Nonpronational Read" value = "true" /> & Lt; Property Name = "Datannucleus. Nonprinctional Draits" Value = "True" /> & Lt; Property Name = "datanucleus.ConnectionURL" value = "Epigin" /> & Lt; / Properties & gt; & Lt; / Persistence unit & gt; & Lt; / Persistence>

Did you mark dependencies in the Java build path -> order and export? Apart from this, I had a problem with the 3G library which requires the dependencies of ourselves, which have been solved by eclipse, but did not work in the runtime because they were not included in the main project, Not the library itself

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ...
