weborb.types.Types error

General

Hi, I have been recently working on an app, which I was testing and running on android devices with API 21+.
Today I decided to check older versions of android to see how it works and I got the following error as soon as a I tried to register the app on backendless:

I have tried the following soulotions so far with no success:

  • Changing the heap size in gradle
  • replacing the backendless jar lib with maven dependency

Please specify which Backendless SDK from maven did you try and on which Android did the problem occur?

3 
maven dependency: com.backendless:backendless:3.0.15.1

Android: I am using an Emulator by Genymotion, Samsung Galaxy S4 , running 4.4.4 (API 19)

Please share your manifest file

Try to explicitly specify SDK

7

I tried and nothing changed

UPDATE:
I tried removing google play services and it worked however this cannot be the fix because my app depends on some of the packages in the google play services.
I am not still not sure what to do.

UPDATE: Solution found
Ok so apparently I had over 64k methods which exceeds the normal dex limit, therefor I had to enable multidex in gradle, which is something I already have done.

I recently found out that android devices that are prior to 5.0.0 (21) do not support multi dex and therefor it would crash on anything below API 21.

The fix:
In the application file where I init the backendless configuration:

public class App extends MultiDexApplication{
...
}

In manifest:

<application
    android:largeHeap="true"
    android:name=".App"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

in app module:

defaultConfig {
    multiDexEnabled true
}
dependencies {
    compile 'com.android.support:multidex:1.0.0'
}
