iOS Build failure for CodenameOne

I've built the iOS version of my app about a month or so ago. Then added a few extra messages to the UI, tested with the Android version and now when I rebuild the iOS version it seems to fail. The error log is at: https://s3.amazonaws.com/codenameone-build-response/621a8710-2900-45a3-afdb-e3a30bdb1265-1504680431641-error.txt
At the bottom of this, the only actual failure I see is:
** ARCHIVE FAILED **
The following build commands failed:
CompileC build/Build/Intermediates/ArchiveIntermediates/MyApplication/IntermediateBuildFilesPath/MyApplication.build/Release-iphoneos/MyApplication.build/Objects-normal/arm64/com_codename1_io_websocket_WebSocketNativeImplImpl.o MyApplication-src/com_codename1_io_websocket_WebSocketNativeImplImpl.m normal arm64 objective-c com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)
Failed xcodebuild step
I have updated the CN1Libs a few days ago. Not really sure what about this is actually failing to build.

Notice that the file com_codename1_io_websocket_WebSocketNativeImplImpl.m is mentioned in the final lines which means that's the file that failed. If you search the file for mentions of com_codename1_io_websocket_WebSocketNativeImplImpl.m you will find:

This might be a bit confusing but it generally means you added the cn1lib for websockets and didn't use it. That's a problem as our VM strips out unused code but the websockets cn1lib needs to include the callback interface which is now stripped away.

SQLite error in android Xamarin Project

I get this exception when hitting this line of code in my project. Any ideas?
line of code:
var JsonData = JsonConvert.DeserializeObject<LoginModel>(ResultData);
exception:
{System.MissingMethodException: Method 'SQLite.Net.Attributes.AutoIncrementAttribute..ctor' not found.
at (wrapper managed-to-native) System.MonoCustomAttrs:IsDefinedInternal (System.Reflection.ICustomAttributeProvider,System.Type)
at System.MonoCustomA...
oddly it works fine if I run the project in Visual Studio for Mac 2017, but when I run it on VS 2017 on Win 10 I get this exception. Exact same code, no changes. So it must be an environmental thing, but I have no clue what.

Can't build streamer tutorial for android on mac

Can't build streamer tutorial_3 for android on mac
I,ve got all environment variables needed.
My eclipse can't to resolve some symbols, but to some of them i can get by pushing F3. It's very strange for me.
Here is the command line output:
23:04:06 **** Build of configuration Default for project Tutorial3 ****

I use ndk-10r and gst-1.4.0.
I know that there is no interfaces/xoverlay in new streamer.
EDIT
I've built ok, but steel got underlines of many glib-types and GST-macross. Here is a screenshot:
what is interesting that i have no underlined headers, for example: i've include pthread.h but have got underlined pthread_t and phtread_key_t....
i think that i have not install some general libraries on my mac, something like libc or what ever...may it couse this problem? The problem is that i can't run my app from eclipse. and for more: i use DS-5 CE IDE

This is most likely because we build the android 1.4.x cerbero packages with the r9d NDK.
You might want to use the r9d NDK until we provide binaries built with a more recent NDK (started some builds to see if everything goes through fine).

Gradle Error for Android Studio

I'm trying out Android Studio on OS X and am running into a mysterious error message. I went through the Google guide to building a simple UI, but when I finished writing the XML file and hit Run in the IDE, I get the following message ("Test2" is the name of the project):
Gradle: Execution failed for task ':Test2:validateDebugSigning'.
> Could not find matching constructor for: org.gradle.tooling.BuildException(java.lang.String)
I have never developed an android app before, so I don't know how common this is. I did a search for this error and found no one encountering the same problem.
I tried the solution from Abhan and I get a new error message:
Error: org.jetbrains.plugins.gradle.settings.GradleSettings cannot be cast to org.jetbrains.plugins.gradle.settings.GradleSettings

It warns you that android plug-in task validateDebugSigning cannot access the debug key. Check your accessibility to the debug.keystore.
On linux or OS X, the default location is ~/.android. On windows, it's in C:\Documents and Settings\.android\ or C:\Users\.android.

Android 4 ICS (AOSP) build error on Ubuntu 10.04

I am trying to build Android 4.0.1_r1 on Ubuntu 10.04 64bit. I have followed all the steps as mentioned in the official build document before I initiated "make -j2" for a "full engineering" lunch type.
After 2 hours of compilation , I got this error :-

Note: external/doclava/src/com/google/doclava/Stubs.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
After this above error , the build stops.
Modifications I did before the build are as follows :-
From /devices folder I removed Google , Samsung and Ti folder so that they are not included in the build.
In the /build/target/product/core.mk I removed the following apps - Browser, HTMLViewer, Contacts
Although I am a complete beginner in Android source development, I'm having this hunch that the modifications may not be the actual cause of the build failure and root cause lies somewhere else. I need some advice on this.
