Hi Mauricio,

Are you using Maven/Gradle dependency or a JAR file built from sources?

mauricio-liell · February 3, 2016, 3:28pm

JAR file 3.0.5

sergey-chupov · February 3, 2016, 3:31pm

How do you link it to the project?

mauricio-liell · February 3, 2016, 3:35pm

Sorry, it’s a gradle dependency of the jar file .

build.gradle:

dependencies {
    ...
    compile project(':backendless')
}

sergey-chupov · February 3, 2016, 3:38pm

Why do you link the whole project with Gradle? You can just add a dependency like the following:

dependencies {
  ...
  compile 'com.backendless:android:3.0.6'
}

mauricio-liell · February 3, 2016, 3:51pm

Your wish is an order

Now an error on initialize:

sergey-chupov · February 3, 2016, 3:55pm

Is it possible for you to send your project to my email sergey.chupov@themidnightcoders.com?
Or else maybe it would help if you show your MainActivity’s onCreate() method and build.gradle file.

mauricio-liell · February 3, 2016, 4:01pm

Yes, I am sending you.

sergey-chupov · February 3, 2016, 4:46pm

Seems we have some problems in the latest version of SDK on Maven Central. We’ll need some time to test it.

For now, you may build backendless.jar from sources on GitHub and just put it into your “libs” project folder. Note that in this case you won’t need the following line:

compile 'com.backendless:android:3.0.6'

For your convenience, I uploaded the latest backendless.jar here: https://drive.google.com/file/d/0B25OdBX1nz_GYzJSTTBNelZRVEk/view?usp=sharing
We shall notify you when we fix the Maven version and then you’ll be able to get rid of jar file dependency.

sergey-chupov · February 3, 2016, 4:50pm

Oh, sorry for misleading you, you don’t need linking the jar. I just knew that we already have a newer SDK version on Maven:

compile 'com.backendless:backendless:3.0.8.1'

mauricio-liell · February 3, 2016, 5:13pm

we return to the Internal client exception

Here’s a link to my test app project. It is as basic as it can be and I am not seeing any errors you’re talking about:

Could you download and run it in Android studio? If it works, try to compare how it is configured (I did the minimum setup - just modified manifest and added backendless via maven).

The BackendlessUser.class works, but other data not.

I created two files based on code generator:

What was the problem with your project? How is different from mine?

Regarding the error, instead of this:

Backendless.Persistence.of(Notas.class).save(nota);

You need to use Async version of the method:

public void saveAsync(AsyncCallback<Notas> callback) {
Backendless.Data.of(Notas.class).save(this, callback);

}

You cannot invoke sync methods on the UI thread of your Android app. Android does not allow network communication on the main thread.
