Can't fix the Libpng issue in eclipse - google-play

when I submit my app, google play send me an email that my app is rejected because of the libpng library, I checked the link they send me but I don't know what exactly should I do after instaling the new libpng on my mac, because the libpng files still exist in the app folder.
I tried to replace the Libs folder of my app with a libs folder contain updated libpng, google play accept the app but the app crash in startup!
Please tell me what should I do exactly to solve this issue.
Thanks,

You should adapt your app so it doesn't crash with the new version of libpng, then re-submit. Without giving details of the crash, and your code which calls libpng no-one can help you.

How to handle MISSING_PLUGIN_EXEPTION in Flutter with Firebase Core Plugin on IOS

for several days I have tried to link my Flutter app with Firebase Database. But unfortunately, whenever I want to start debugging the compiler gives back a missing plugin exemption concerning the firebase_core package. I have already seen some entries referring to this issue here on stack overflow but none of them worked for me.
I have already followed the instruction steps by the installation guide on Firebase and included the Google Service File in my Xcode project.
I already did flutter clean, deleted the pods folder and the pod file.lock file in IOS, tried to include the Firebase SDK package by using the add package option in Xcode.
In the past, the connection between my Flutter project and the Firebase Database already worked but somehow it won't work now.
I think that my issue deals with the new step in the installation process for Firebase Connection when I am asked to make use of the Firebase SDK in Xcode.
In the following I'll add some more pictures for illustration. If someone had the same/a similar issue, it would be a huge help for me.

Issue after submitting my app to TestFlight

We have discovered one or more issues with your recent delivery for "AppName". To process your delivery, the following issues must be corrected:
Invalid Bundle - One or more dynamic libraries that are referenced by your app are not present in the dylib search path.
Once these issues have been corrected, you can then redeliver the corrected binary.
Regards,
The App Store team
For me the following worked:
i updated cocoapods if You have troubles doing so this link may help
deleted MyProjectTests (that i wasn't using)
deleted my Pods/ folder and Podfile.lock
made pod install
rebooted my mac
and the problem is gone
I have just seen the problem after install the app in a real device, but crashed (in the simulator works). My app missing a library installed with Cocoapods.

"/Applications/Xcode.app: a sealed resource is missing or invalid" error while validating Xcode installation

Today I got the memo from Apple as probably every other Apple developer about potentially infected Xcode installations. (https://developer.apple.com/news/?id=09222015a)
I followed the instructions and tried to validate my Xcode app using the command mentioned. (spctl --assess --verbose /Applications/Xcode.app) The program ran for a while and exited with a "/Applications/Xcode.app: a sealed resource is missing or invalid" message.
The article says "Any result other than ‘accepted’ or any source other than ‘Mac App Store’, ‘Apple System’ or ‘Apple’ indicates that the application signature is not valid for Xcode." However, I'm actually pretty sure my Xcode copy is legitimate (downloaded and updated via App Store with Gatekeeper enabled) so I thought maybe there could be another problem preventing it to validate as it should.
Do you have any ideas what this error message actually means? Do you think I need to reinstall Xcode just in case?
Thanks in advance for your help.
The false positive validation issue appears to be caused by containing previous iOS SDKs in order to be backwards compatible.
A clean install will completely wipe the SDK directories. When you run the validation test after a clean install it will pass. Once you copy previous iOS versions, which, for us, is iOS 8 for iPhone, the validation will fail.
This scenario was tested after updating to XCode 7.0.1 (7A1001) which was released earlier this afternoon.
In order to avoid a clean install, you can temporarily remove the previous SDK version from their respective location, and run the validation. Then, once the validation passes, copy the files back where they belong.
I was getting the same message "a sealed resource is missing or invalid". However i was able to rectify the issue by going into the App Store and downloading the latest version of Xcode - Version 7.0 (7A220), and this seems to have rectified the issue.
Although i did first try updating Xcode through the updates section on the App Store, but for some reason this didn't work. So i would recommend going into the App Store > Search for Xcode > Then install the latest version available to you.
Depending upon gatekeeper settings.please check gatekeeper settings to allow anywhere and revalidate Xcode.

Getting firebird to work under OSX with Delphi Firemonkey app

Does anyone know of a guide to getting Firebird working under OSX for Delphi apps?
I am using the InterBase Express components but when I start my app I get the error saying that libgds.dylib is missing. I have renamed the libfbclient.dylib to libgds.dylib. I have even made a copy in the original path and done a symbolic link to the /usr/local/lib folder (as is the case with libfbclient.dylib).
Here is what I have tried...
I have added '/usr/local/lib' to the paths in the target profile.
I have tried copying the file into the package
I have copied the file to my windows machine and then distribute it using the project deployment options.
Nothing appears to work. I'm not trying to create a redistributable package at this point. I just want to get the app working for debug.
One further bit of information. I installed the standard Firebird package rather than the Lipo package. I confess to not really understanding the difference. I am going to try installing the Lipo package now to see if that makes a difference.
Thanks in advance,
Martin
Solution found. The problem was the package that I installed.
After installing the Lipo package it appeared to find the dylib and continue.
Im not there yet as now I am getting a Permission Denied error trying to create the database in the Documents folder. I guess I will post another question if I cant get to the bottom of this one.

Phonegap build problems

i have recently created my first app and got it onto my ipad, however, i wasn't getting the "phonegap is working" alert. After digging around the code, it seems the onDeviceReady function is not running and i narrowed it down to the phonegap-1.3.0.js, which was missing. I thought that phonegap build this file automatically, but can't seem to find it anywhere. can someone tell me hoe to generate this file or where i can download it?
You should check that you have all the phonegap files that you need, and download the zip file from here: http://phonegap.com/download-thankyou (assuming you're ok with using the latest PhoneGap).
