Unable to start activity. java.lang.IllegalStateException: Client not initialized

I would love some help. I am new using dropbox api, I am using the resources available here:https://github.com/dropbox/dropbox-sdk-java
It is working fine, I can upload files perfectly, but then, when I download a file, you can see that is downloaded but then the app crashes with the following error:
Caused by: java.lang.IllegalStateException: Client not initialized.
This is my git repository, https://github.com/ghilbing/ProbandoDropbox
If you can help me find the error, I would be really thankful.
Thanks in advance for your help.

Exception while Dropbox API tries to read a resource - might be multidex issue?

I have an Android app with Dropbox support. Lately I've started getting an exception for some users. I can not reproduce it. It affects just a few users. The exception happens when Dropbox tries to access /sdk-version.txt which is one of their resources. On Android Studio I can see the resource is there, here is a screenshot:
And like I said, it doesn't happen for me or for most of my users. If I use apktool on my apk, the sdk-version.txt file shows up on a folder called unknown. I see a lot of other files there but most have a package, this one doesn't. Not sure if that matters.
I also have this line on my gradle file multiDexKeepFile file('multidex-config.txt') and in there I have:
com.dropbox.core.DbxRequestUtil
com.dropbox.core.http.HttpRequestor
com.dropbox.core.DbxSdkVersion
Those were all attempts at fixing this but it didn't help.
So far the exception has happened on Android 5 and 6 across multiple manufacturers. This is the exception:

This isn't a direct solution.
You can integrate fabric clashlytics into your app to get a full report on the cause of the exception and information on the type and OS of devices experiencing the Exception.

traceview command run issue

I am trying to use traceview to run some profiling against an Android application. I have wrapped the code that I want to trace with the following lines:
Debug.startMethodTracing("xxx");
// code
Debug.stopMethodTracing();
It successfully generated a trace file, that I pulled from sdcard using the following command line:
$./traceview ~/code/packages/performance_trance.trace
Exception in thread "main" java.lang.NoSuchMethodError: java.util.Arrays.copyOf([II)[I

I cannot understand this error message and I didn't find anything useful on Google.
Any help would be much appreciated.
Thanks!

try to open the file with your eclipse (with adt plugin)

Eclipse: Unable to execute dex: stackOverflowError

When trying to build my android project I get the following error. I've been able to compile without complain on other machines with (what I believe to be) the exact same setup (ubuntu 11.10/eclipse indigo/same android sdk)
Unable to execute dex: java.lang.StackOverflowError. Check the Eclipse log for stack trace.
Conversion to Dalvik format failed: Unable to execute dex: java.lang.StackOverflowError. Check the Eclipse log for stack trace.
In the eclipse log all I get is about 2 pages of :
java.lang.StackOverflowError

Any suggestions would be greatly appreciated. :)
Edit:
Searching the log files I also found that I got this error right before.
Warning: A handler conflict occurred. This may disable some commands.

I had got the same error and was able to solve it... Hope it helps you...
Look in the bin folder of your project directory and you will see .dex files generated.. Delete them and try to run your project again...
