Could not find class/NoClassDefFoundError BeaconService while using SDK in remote service #25

Closed Mtx88 closed 10 years ago

Our application runs in a remote service.

Android Manifest File:

<service
            android:name="..."
            android:process=":remote" >
            <intent-filter>
                <action android:name="..." />
            </intent-filter>
</service>

I first added the BeaconService like this

<service android:name="com.estimote.sdk.service.BeaconService"
         android:exported="false"/>

But then I got the following error

Looking for a solution I tried adding: android:process=":remote" to the BeaconService

<service android:name="com.estimote.sdk.service.BeaconService"
         android:process=":remote"
         android:exported="true"/>

This did fix the error and I was able to receive data from the listeners but for some reason this only works on my Nexus 5 which runs Android KitKat 4.4. This solution did NOT work on my Samsung S3 which runs on an older version of Android.

Jar path: libs\estimote-sdk-preview.jar

I understand that BLE only works on 4.3+ but should it just crash like that?

Any advice?

No, it should be more clear for the logs.

I'll leave it open to make sure that errors are more friendly when it runs on non 4.3+ device.
