java.lang.UnsatisfiedLinkError: No implementation found for void com.netdatasoft.android.divvydrive.scanner.views.CameraView.decode

I had an image scanning activity with openCV infrastructure before. However, even though there is no code change at the moment, it gives an error and restarts the application. It gives a warning to a method in Asynctask.

UnsatisfiedLinkError when trying to create new instance of TessBaseAPI

This is a weird error because it doesn't happen every time - mostly rare - so it's difficult to debug.
This is the line where the error occurs:
TessBaseAPI tessBaseApi = new TessBaseAPI();
I use this library to connect Tesseract with Android.
The error log:
E/linker: package com.app.myapp: library "/system/lib64/libjpeg.so"

Any kind of help would be appreciated.

App Crash but there is no error in the code

I have list of items in the RecyclerView and if I click the item then it should display corresponding items. If I click the item then the app is crashing with the below message. Its not showing any error in the code. Is it a library issue? or JSON Issue? I am new to Android Development. Any help is highly appreciated.

Just now I found the issue. Its due syntax error in my SQL statement where I missed e in the where condition so, its not able to fetch data. After syntax error fix then I am able to pull data without any issues. Thanks everyone for your help.

java.lang.VerifyError when downloading data with jsoup in Android N

I compiled my Android app for the new Android N version and then tried to test it on an emulator. It runs normally until I try to download and parse some website data using the "jsoup" library. Then I get this java.lang.VerifyError:

While researching on VerifyErrors, I came across some solutions, like cleaning the project build folder. But those solutions didn't help.
What I am wondering is, what [0x140B] Invalid reg type for array index means. This may be the thing I have to resolve, but I don't know how.
Edit:
So I dove a bit deeper into the problem and located the crash inside the block named "InBody" in org.jsoup.parser.HtmlTreeBuilderState, lines 244-759. I don't know why, but when I set breakpoints there, the program never stops there, so I have no clue at which exact position inside this block the crash happens. But as the error message speaks of some sort of array index, I figured it might be one of the 6 for-loops I found that have something to do with the data type "Element": They are at lines 305, 388, 561, 582, 602 and 640

Disable jack.
I got the same error when I enable jack. I disabled jack and compiled, no error. Then I copied jsoup source code to my project folder, enabled jack and compiled, no error. So I think it is a bug of jill, the tool to convert *.class to *.jack.

No Class Def Found Error Android-Bolts Parse

I am using Android Studio (latest version) for developing my app. I use Parse as a backend solution. Everything was working smooth until i found out that parse have new release and i wanted to upgrade from Parse-1.7.1.jar to Parse-1.8.3.jar (latest version).
Since parse now use Bolts lib i also added the library like this:
compile 'com.parse.bolts:bolts-android:1.1.4'
Parse.initialize();
Also i use the facebook-sdk for dont know if this have to do anything with this mess.
All i get in my Application onCreate method is this error
