I recently started using proguard in my project.
I created test crash (in App class)
I received next error -

I run script
java -jar retrace.jar -verbose d:/mapping.txt d:/obf.txt > d:/fixed.txt
to obfuskate code, and receive next:

So I just received method, in wich exception was caught. I would like to get the line, if it is possible, please help!
PS also, I tried
retrace.bat -verbose d:/mapping.txt d:/obf.txt > d:/out.txt
and received the same result
You need to add next rule to proguard config file:
-keepattributes SourceFile,LineNumberTable
If you want to hide actual source file name add next rule:
-renamesourcefileattribute SomeName
and all file names will be renamed to SomeName.java, but after deobfuscation you will have class name and line number which will allow you to restore actual line of code

What happened with my apk?
I am wondering if this is some bug in Android Studio or I am simply lack od knowladge but straight to the point.
I am writing simple client-server via bluetooth app on android. At some point I encoured following problem:

For what I understand Android Studio can't find method parujUrzadzenia(View) that is marked in button6's properties as onClick method...the funny thing is i deleted this button in my way of solving this problem.
I can't post picture of my project due to low reputation but like I said. I've deleted the reference to method from .xml and method from .java file and got an error saying that there is no required onClick method. So I deleted this whole button and still got this error.
Any advices will be greatly appreciated.
I've enabled android proguard. After sing in i've run my app on device. its throws below error.

What class need to keep in proguard? if disable proguard its working correctly.
Decided to use Scandit SDK to get the barcode scanning feature in my app. Unfortunately, since I'm relatively new to Android development and Java in general I've run into a few issues that I can't seem to work out. The demo that Scandit provided doesn't give any errors(runs fine) but crashes when I try to start it up (pressing a button from one activity is meant to start it up). I've tried reading the logcat and googling a solution to the problems but I'm not getting the right solutions. Does anyone have an idea of what I'm doing wrong?
Logcat is provided below:

I came across this problem as well, my solution was to extract the library files and put them as their files in the lib folder
The library basically isn't being exported with it
EDIT
So I checked out my project, basically I did these things:
In the libs folder I have a new folder called armeabi and inside that I have libscanditsdk-android-3.3.1.so
Then in my build path I have also referenced the jar file that they provide:
<classpathentry exported="true" kind="lib" path="C:/GIT/Android/FwayScannerProject/FwayScanner/libs/scanditsdk-barcodepicker-android-3.3.1.jar"/>
I am getting the error below when I try to login through facebook plugin for Android.
The app basically crashes "stopped", Any ideas will be appreciated.
