Working on ARM, not working on Intel Atom (x86)...

Jaros_awKowalczyk

Hi, is there is some way to run Sample Applications on Emulator with x86 chipset (which on virtualized machines is so much faster than ARM)?
Those applications are working on ARM, but not working on Intel... Don't know why.
In running sample of HelloWorld App LogCat shows me:

, but on ARM works fine.

The answer is actually pretty simple and with no workaround. If you look at the ArcGIS runtime for Android, you will notice that it has both a jar and native *.so libraries. Obviously, the jar is truly cross platform. However, java code has the ability to call into native libraries which prevents the Java code from being cross platform unless the native libraries are compiled for all the platforms you want. ESRI only distributes armeabi and armeabi-v7a *.so libraries. Therefore, when you try to run it on an Intel based emulator, it will try to find an x86 version of the native library and will fail causing the app to crash immediately. that is what the "UnsatisfiedLinkError" is complaining about in your log.

Therefore, ESRI needs to recompile their native library for x86 and distribute that *.dll along with the ArcGIS runtime for Android. Until then, nothing you can do.

I don't know how that should help me (i didn't mention that i've done it already, it's my fault, ok, and other applications are running great but thanks for answer.

Until then, nothing you can do.

OK. So welcome 'bullet time mode on' on ARM! When i was reading your message i thought for a while that it can be fault that i'm not using Linux (.so) for programming but Windows (which using .dll), but you 'calm me down' and I have to admin that until they don't repair that (i think it's profitable because time is money) that programming and running appliactions with ArcGIS for Android is like playing Max Payne! Thank you esri for so much entertainment!

Happy st. Valentine's Day.

Not a fix but a similar problem

I am trying to get the samples to run on an Android vm running within virtual-box.

The vm has the houdini lib ... Angry Birds Space plays fine (fine as in fast for an emulator)

Other android apps (SQLite based ones i.e no MapView) deploy quickly from eclipse.

But the mapview remains blank (network is fine)

Wow I posted this days ago with no replies...

...ESRI needs to recompile their native library for x86 and distribute that *.dll along with the ArcGIS runtime for Android...

Yes but technically it's still a .so file regardless of the platform because Android is unix based. I

So how do we get ArcGIS to build this for us?

MáximoMussini

Does anyone know if ESRI is working on x86 libraries for this?

DanO_Neill

We are considering adding x86 build for the emulator, but currently recommend testing and building on a physical device. I suggest submitting this request to ArcGIS Ideas.

ThomasBinu

try the new genymotion emulator. Its much faster than than the x86 emulator.

MáximoMussini

As a matter of fact I started using it yesterday. Have you tested that it works with ArcGIS for Android?

ThomasBinu

Yes I tried, it mostly works but there are still some weird errors especially with callouts

MáximoMussini

It's not working for me. From what I understand, Genymotion also uses x86.
If I don't provide a libruntimecore_java.so for x86 it crashes:
java.lang.UnsatisfiedLinkError: Couldn't load runtimecore_java from loader

If you provide a .so for x86 (an invalid one) it doesn't crash, but naturally, it doesn't work either.

I think ESRI should put more though into this. x86 emulation has clearly been adopted by the whole Android community, any library vendor should provide an x86 version of the native libraries used.

DanO_Neill

Trying to keep these posts in synch. I will add that we are testing with genymotion emulator as well since this post referenced it.

RobertHewlett2

This is what is working for me:

Some of the samples with the following combination of software:
'SDK ADT Bundle for Windows' (version 22.3) (64 bit)
http://developer.android.com/sdk/index.html#download

ArcGIS Runtime for Android 10.2 (local)
https://developers.arcgis.com/en/android/

I did not install the the genymotion plugin for eclipse, the DDMS (adb) picked up the emulator. Previously, I had to do adb connect at the command-line.

I found that genymotion likes virtualbox to be running before it starts.
