I used NDK to design an app.but I got a problem.
andriod\MyApplication2\app\build\intermediates\ndk\debug\Android.mk:
No such file or directory
in the setup-toolchain.mk.like this
But I check
\build\intermediates\ndk\debug\
Android.mk
is here.
like this
How can I solve this problem? Please help me.
Whoa, where did you get the idea to structure your project like this? Android.mk should go under app/src/main/jni. Check out the Google NDK samples repository to see some properly structured projects. The hello-jni example is a great one to start with.

I 'am a newbie programmer.
Today I want to install and configuration formidable for my project.
https://www.npmjs.com/package/formidable
I have question:
where I find information about how to save files to dir? I see on npmjs example code with express.js, but in this code not include information about save, documentation also not included information about save files to dir.
How I should read that documentation like this? I will be grateful for any comments, probably at the moment I don't think like programmer.
The documentation says that files will be saved ...
You should try the examples before making random guesses.
I am developing a flutter app. I want to let the user select some sounds.
When selected, I want the app to play its mp3 file in the assets folder. I tried with AudioPlayer plugin but I haven't achieved to play local files...
I have been searching for awhile and I haven't found any good answer to my questions, furthermore, the posts were created 2 or 1 year ago, so maybe we need an updated answer.
I have found this post: How to play local mp3 file with audioplayer plugin in Flutter
but my project doesn't find this package import 'package:path_provider/path_provider.dart'; [THIS PART IS SOLVED]
And when flutter will have a built-in audio manager? Are they/you working on it?
Thanks in advance!
EDIT: Also, I would like to play different mp3 at the same time, with different volume. Is it possible?
That import directive you see tells Dart that a particular source file uses classes from a different source file. The package: prefix tells Dart that the imported file is part of an external dependency. So you need to tell your project that you have a dependency. This is done in the pubspec.yaml file.
Dart's pub dependency manager takes care of finding the right version of the dependency for you, and downloading it. Add the path_provider package to your pubspec.yaml file. Each package's installing tab shows how to do this.
You can find a whole library of useful flutter (and Dart) packages here.
path_provider is a special type of package called a plugin which contains some Dart code together with iOS and Android specific code. This is necessary because playing audio or creating local files is platform specific.
I am trying Griffon for rapid desktop development, as it is so much quicker to write Ruby-style code than Java, and i enjoy this clean ruby architecture.
Please understand that i am just starting - maybe my question is stupid.
I wanted to ask, if/how/how simply 'native' java .jar libraries can be used (just any .jar, there are so many). My question, b/c to start with groovy, i did the groovy-koans. there, classed were either .java or .groovy, and could 'work together'. such my thought, that might be possible with .jars (that is, libraries, plugins) alike?
Thank you!
You can follow the instruction in http://griffon.codehaus.org/guide/latest/guide/configuration.html#dependencyResolution to add dependency to Jar files stored in Maven repository.
You can also put the Jar files to lib folder in your Griffon project.
I am having difficulty getting a new version of a 3rd party SDK to import into Android Studio.
In the earlier version they released .jar and .so files which I copied into /lib and /jniLibs and then added the lib files into the Android Studio app and everything worked. The app ran, used the libraries and all was good in the world. Recently a new version of this SDK was released but in this new release they have resource files (but they are not compiled into the jar/so files; there is a $Rstring.class files that they say I should import. I've now spent days copying into various locations in the app project with no luck and the missing strings result in crashes when calling their SDK.
OK, I figure I'd try to import their SDK folder (which is how they document to do it if you are using Eclipse). Well, no matter what I've tried and after selecting the folder or SDK's project file I get a dialog asking for the Eclipse workspace and a list of what appears to be source file names. I can't get past this dialog because obviously I don't have their files.
Has anyone run into this and found a solution; perhaps I'm missing something in the process but after spending the better part of 3-4 days trying and searching and trying more things I'm hopeful for help from the community.
OK, I found the answer and it was a combination of issues in how this particular 3rd party distributed the SDK and not fully understanding the menu.
The 3rd party in question packaged the SDK with the output files of the build as well as files that needed to be imported making an import alone to not work.
Combine this with menu confusion: File->Import Module is NOT the same as New->Modules->Import Existing Project only added to the confusion.
The solution ended up being to use the File->Import Module which appears to be a very different operation and once done most of the issues where solved. It solved the main issues I asked above which was missing resourced.
Still missing was the library (.jar) files which had to me copied into the app's lib folder and "added as library" but the .SO files did not need to be copied and in fact doing that resulted in a duplicate files warning.
I'm not sure I can fully explain what happened but what I think happened is that the "module" was where the app read the .so and string resources from but was unable to load the .jar files because (I suspect) these files where not part of the module but rather where outputs of building the source and it was removing the source files which caused the inability of the new->Module->Import to fail.
Hopefully this makes sense or at least give someone an idea of what to look for when/if they run into a similar issue.
I'm a beginner I am using using Microsoft Visual C++. I need a step by step walkthrough from downloading up till actually using libcurl if anyone can help? I don't know much terminology though.
Everyone seems to skip all that and goes straight into putting #include in their files but I don't know how to get to that step.
I know I have to tell Visual C++ that I'm using another library but how do I do that? How do I configure this library and include the directories?
Any help is very welcome!
they have a .pdf explaining step by step how to build a project with libcurl, here is the link
http://curl.haxx.se/libcurl/c/visual_studio.pdf
hope that helps
