I'm trying to find the minimum volume bounding box given a set of point clouds in Android. This repo seem to contain the solution: https://github.com/gabyx/ApproxMVBB
But I'm having trouble installing it into my Android Project.
I've tried:
using Cmake to build eigen (not approxMVBB yet) -> it fail at build time.
using top level Cmake to build both eigen and approxMVBB in Android -> cant seem to find Eigen3Config.cmake
built both of these two libs on my computer (Windows 10) using minGW64 -> created a dll and a dll.a file -> which seem to be incompatible with Android.
copy {eigen_dir}/Eigen directly into scr/main/cpp, then hardcoded ApproxMVBB CMakeList with "include_directories(Eigen)" -> android build seem to have issue with Ninja.
I'm currently thinking that ApproxMVBB is simply incompatible with Android devices, but I'm not so sure. Any help or confirmation would be highly appriciated.
Nvm, I got frustrated so I wrote a MVBB for Java.
The code is here: https://github.com/ginofft/ARCoreDemo/blob/master/MVBB_Java/src/main/java/scr/MVBB.java

I am a Android Developer.
Recently, I was working on the compilation of MapBox SDK.
I want to follow the official website steps，But I developed it on Windows，
I want to change the source code，instead of just using aar.
enter image description here
So,Can someone tell me what to do?thank you.
Yesterday I tried to import the mapbox project,download CMake,cUrl..,I find the build.gradle of module，There is a note：
// Load build system information. If this file does not exist, run
// `make platform/android/configuration.gradle`
apply from: rootProject.file('configuration.gradle')
make,it's linux command，I use the windows system,so I download the MinGW.
but when I use this command to build configuration.gradle, i got failed:
make:***FATAL***platform/android/configuration.gradle:unknown action keyword
so i tried to use this code in android studio Terminal,but it can't use make、cmake or other,so how can i build this file.
I've been getting this mistake：
Error:(22, 0) Could not read script 'F:\AndroidStudio\AndroidStudio_WorkSpace\mapbox-gl-native-master\platform\android\configuration.gradle' as it does not exist.
or someone has ever done this,could you give me your configuration.gradle,so i can modify it.
thank you.
You should be able to compile the SDK in Windows. The easiest way is to use CMake from within Android Studio. Note however that CMake support is only for the 64 bit version (I believe) not for the 32 bit version of Studio.
If you're building from the command line, then 32 bit or 64 bit both work because NDK is available for either. To do that, you'd write something like:
./gradlew.bat -Pmapbox.buildtype=debug -Pmapbox.abis=all :MapboxGLAndroidSDKTestApp:assembleDebug
I'm fighting with that issue for 2 days already and can't find any solution.
I have an Xamarin Android app in Visual Studio 2017 consisting of three projects:
Xamarin.Android project (main one)
Android-specific unit tests run on the device - project of type NUnit 3 Test Project (Android) created using NUnit Templates for Visual Studio
Platform-independent unit tests project (project of type Unit Test Project (.NET Framework))
Everything worked just fine until now. When I selected my main project as the Startup one, my app was deployed to the device/emulator. When I selected my Android-specific unit tests project, the test project was deployed and unit tests executed by nUnit Xamarin Runners on the device/emulator.
However few days ago I updated my Visual Studio 2017 with the newest available update and now, when trying to build this android-specific unit tests project I get the following error:
The file "obj\Debug\android\bin\packaged_resources" does not exist.
I've searched everywhere, including this and this SO topics. I also totally reinstalled Visual Studio 2017 and Xamarin with Android SDK included. Nothing helped. From what I read I suspect there is something wrong with the versions of Android SDK Build-tools I have installed. Here's what I have currently installed in SDK Manager:
As the other SO threads suggested, I tried uninstalling the newest Android SDK Build-tools (25.0.2) and installed version 23.0.3 (all my projects target Android 6.0), but it also doesn't help, I still have the same error.
Maybe it's worth adding that this issue may have started to happen when I tried to implement RecyclerView in my app reading this tutorial, where they suggested to install Android 7.1.1 (API 25) in SDK Manager. However I undoed my all changes after that and even reintalled VS2017 + Xamarin.
Do you have any other idea why this can be ? I'd really appreciate any help. Thanks!
EDIT 2017-04-09:
Egh, I removed VS2017, installed VS2015 with brand new Android SDK and still the same issue :(
I've finally found what was the issue. It wasn't related to any component from SDK Manager or VS version.
Following localization tutorial from developer.xamarin.com, I played a bit with Strings.xml in my Android project. I wanted to have my Activities Label taken from resources as well, so in the ActivityAttribute I defined:
[Activity(Label = "#string/peopleListTitle")]
and added this value in Strings.xml file:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<!-------Other resources values ----->
<string name="peopleListTitle">People List</string>
</resources>
In that case my build is failing with above-mentioned error:
The file "obj\Debug\android\bin\packaged_resources" does not exist
When I change ActivityAttribute to use a string directly:
[Activity(Label = "People List")]
the build is passing without any issues.
I managed to find a solution, but actually I don't know why it's not building when I try to use Label text defined in Strings.xml.
BTW, I managed to find what's the problem by setting build output verbosity to Diagnostic in Tools -> Options -> Projects and Solutions -> Build and Run which gives a detailed info why the build failed in the Output window.
I had the same problem. After removing the dash "-" sign from the image file name, the problem is solved. Bad error message! It should not be:
The file "obj\Debug\android\bin\packaged_resources" does not exist.
Writing an error message like this causing the Developer to think about something else while the problem is the illegal file name.
I had the same issue when I added a new image as a resource.
There was a '-' in the file name (Invalid resource name character). I renamed & removed that character and all good.
Resource name can only consist of 0-9,a-z or A-Z or combination of any.
I had the same problem, and i removed all image file name have "-" character. My problem solved
Another reason for this error is that you may have a float number as your version number. In my case I changed it to a integer and everything worked fine. (I found the error by switching the build output to Detailed)
Simply it worked.
In one case I copied and pasted previous working "packaged_resources"
in the bin folder.[the problem was it did not reflect the UI changes]
Other I opened the visual studio as
administrator.
Next changed the "Minimum target to Android" to lower
apis in the project properties windows.
I suggest not touching the code behind of the design. If you get this error simply pull some button from the tool bar into the design and visual studio will come to its consciousness that there is change in UI. Next click on save all so that it make necessary change in the designer file.
Mine was a different solution (and only half a day lost): I was having trouble getting Hockey app to match crashes against the correct version of the app and realised it uses VersionCode not VersionName so I change my code to "0.0.34" the same as the name. For some still unknown reason the app built and deployed to devices for about 3 days before I started getting this error The file "obj\Debug\android\bin\packaged_resources" does not exist. Setting it back to a numeric value fixed the problem.
I found the problem by looking back through my GIT logs and rebuild each push until I found the one that caused the problem.
It just because the Version Code,I set Code by '1.0',The file "obj\Debug\android\bin\packaged_resources" does not exist.;And I set it by '1',everything is ok.
Had the same error, the way I got over it was crank up the Android SDK manager and install all updates and remove any obsolete packages. This happened to me because I was targeting something newer which was not installed.
Check to see if there are any unused entries in resources.designer.cs if there are any manually remove those entries.
This will fix the issue.
After following several online suggestions - updating SDK, updating Xamarin etc - none of which worked for me.
Finally found that I had an activity for a Android provider to Alarm clock in my AndroidManifest file as below
<activity
android:name="com.njcommuter.droid/android.provider.AlarmClock"
android:label="AlarmClock"
.....
/>
Removing this line - and rebuilding worked fine without any errors and was able to deploy solution successfully.
Note : testing this by putting the line back, and I get same error again on rebuilding.
It can be linked to using any android provider which creates the package for it, not necessarily AlarmClock only.
This error is, somewhat of, a wrapper for what can be multiple reasons that that the file was not created. The key is to look in the detailed output and look for the underlying error causing the file creation failure.
In my case, I had corrupted icon.png files (generated right from from the VS xamarin nunit template, no less!). Once I put in valid png files, everything was built fine.
Another reason for this error, if that the android NDK (not android SDK) isn't right, change de version can resolve the problem: go to Tools/Options/Xamarin/android Configurator and change de folder, in my case I've three, the last one can't compile, but the second folder with version xx.r11c do it.
For me it was Target Android Version.I had it set to
but changing it to Compiling version(for me it was the latest platform) resolved the issue.
I'd like to do Android development in Clojure, using the Cursive plugin in Android Studio. I've seen several posts where people have stated that it is possible, but I haven't been able to get it working.
When I try to build, I get errors reported where I'm trying to call Clojure from Java:
Error:(6, 18) error: package com.domain does not exist
Error:(15, 49) error: cannot find symbol variable tiny
Here's what I tried:
I already have Cursive running in IntelliJ with leiningen, building and running standalone Clojure apps
Start Android Studio, version 1.5.1
Create a new Android project. Selected API level 15, Empty Activity
Install Cursive plugin, as per this post:
Is it possible to get the Cursive Plugin installed with Android Studio?
Add clojure jar to classpath: Open module settings, dependencies, +Library Dependency, search for and select org.clojure:clojure:1.8.0-RC5
Switch from Android view to Project view, to create Clojure src directory: select app/src/main and create new directory clojure
The next step is to create a Clojure source file, which can be called from Java, using the example in this post: Calling clojure from java
Select src directory clojure, right-click New Clojure Namespace and enter: com.domain.tiny (to match the ns used in the example)
Paste the code from the example above into the new file (note that the ns in the new file was tiny and should have been com.domain.tiny)
It will say File tiny.clj is not under a source root so click on Add source root. Now we have both src/java and src/clojure set as src roots
Build the project. At this point it looks like everything is happy, no syntax errors in either the Java or Clojure code. We can deploy and run the (almost) empty Android project, and run a local REPL to load and test our Clojure code.
We want to call some Clojure code from Java, so add the following code to MainActivity (again, from the example above):
System.out.println("(binomial 5 3): " + tiny.binomial(5, 3));
System.out.println("(binomial 10042, 111): " + tiny.binomial(10042, 111));
Android Studio can find the package com.domain.tiny and the tiny class, no syntax errors, so looks good
Now try and build the project - at this point I get an error:
Error:(6, 18) error: package com.domain does not exist
Error:(15, 49) error: cannot find symbol variable tiny
At this point, I'm stuck. I'm guessing that even though the compiler is seeing the Clojure code ok, there's still something missing in the build process. Does leiningen need to be involved? If so, I don't know how, or what I might have to put in the project.clj configuration file.
Anyone have any ideas? Thanks!
Edit:
This appears to not be possible right now. This is because Android Studio requires projects to use Gradle, and the Clojure Gradle plugin is incompatible with the Android one. This may work in the future, but we couldn't make it work right now.
Original answer:
Thanks for the detailed issue. I guess that your Clojure code has to be AOT compiled for this to work. To enable this, check the settings under Settings->Build, Execution, Deployment->Compiler->Clojure Compiler. If you enable compilation for your Clojure namespaces, does that help?
If I change some code, save, and Run, it runs the last version of the program, not what I just saved. The only way I can make it update is if I Clean the project, Build the project, and then Run the project. Is there some way to avoid this tedium?
I spent some time create two dummy projects (one Android and one Java) and have a play with it, and finally come up with a workaround which is not used very often but able to solve your requirements.
First, I will explain your question a bit more (based on my understanding and what I have tried) so that other people can have a more clear understand about what is happened here.
According to the conversation in comments:
could you tell me what you have in following setting: project->properties->Builder ? – Sudar Nimalan
#SudarNimalan: I am not sure this is what you are asking, but: there's text that says "Configure the builders for this project", and under it is a single option, "Java builder", which is selected (checked). – shino
for android project, there should be, "Android Resource Manager", "Android Pre Compiler", "Java Builder", "Android Package Builder" in this order, chould you add those and try? – Sudar Nimalan
#SudarNimalan: I owe you an apology; I do have those four components. My "project" is split into 4 projects - "core", "core-android", "core-desktop", and "core-html". It's a little weird because I set it up with the libGDX project setup UI, and I was looking at the 'core' project when I answered your question. My 'core-android' project has all four (in that order), and it is the one that has the problem in my question. – shino
Scenario:
You have 4 project:
core: a regular java project (common pure java code here)
core-android: an Android application project.
core-desktop: not related to question so ignored.
core-html: not related to question so ignored.
The core-android project has dependency on core project, by adding core to core-android's build path (Properties -> Java Build Path -> Projects -> Add ...) and export list (Properties -> Java Build Path -> Order and Export).
Problem (Not Really):
Change some code in core and save it, run core-android, eclipse install last compiled apk, not the new one with change.
Reason:
The is the expected behavior, the way you used to reference core project in core-android only create a weak link (or something sort of) between core and core-android, the core-andorid's auto-build script doesn't aware any changes made in core. You have to clean the project (only need clean core-android project) so that Eclipse can delete the existing apk (under bin directory) and re-generate the apk (with the latest code changes from core).
See Xav's comments below, Android SDK tools should aware changes from plain Java project under project build path, and it does not behaviour this feature normally at the moment.
Note that if core is an Android Library project, then there is no problem and your core-android project will aware any changes in core project (java code, android resource and etc), if core is only used in core-android, this could also be a workaround: turn Java project core into Android library project.
Workaround (Eclipse Link Source):
There is another way (not commonly used) for adding soft link between projects:
First, you need remove core project from core-android's build path, this will also remove it from Export and Order list.
Right click core-android, choose Build Path -> Link Source ... Add ../core/src as Linked Folder Location and src-lib1 as Folder Name,see screen screen in the end.
This create a symbolic link src-lib1 under core-android in Package Explorer windows point to core's src foder, in the file system, you still have two separate project folder. Now if you change some code in core and run core-android, Eclipse will build and install latest apk. No need to clean core-android project.
Link Source Window:
Final look in Package Explorer:
You should always consider the normal approach as first option, after all, manual clean project is not a big deal compare to the unusual approach I described above.
Please follow this steps..
1. Project--> Build Automatically been checked??
2. Please following setting: project->properties->Builder like that?
Check below image.
And Also Check Below Settings.
Also Check Below Image
IF problem continues then please Update your ADT & SDK.
Hope it works for you .
Navigate to Windows->Preferences->Android->Build. Make sure that the checkbox "Skip packaging and dexing..." is NOT checked.
The Problem is the In your Eclipse, go to Project Properties - Builder, There is one CheckBox with AndroidPackageBuilder that is required to be Checked True. Now everytime you will do any changes in you project that will be reflected in your build and the Compiler will never say that
"Application Already Deployed, No need to Reinstall"
This will work evenif you dont have selected Build Automatically, Because everytime you run by clicking Run icon or Ctrl+F11 that will first Build the Project and Then Run it. So The requirement is just to Enable the Android Package Builder
You won't believe how easy and silly is the solution
On Eclipse,
go to Window-Prefences->run/debug ->launching
And then, on Save required dirty editors before launching :
choose the Prompt option,
Apply and OK
On Windows 7 (64 bit) with the Android SDK working perfectly with Eclipse - my first android application, using the first "Hello World" sample (found here - http://docs.xamarin.com/android/getting_started/hello_world - from Xamarin)
fails with the error "the OutputPath property who is not set for project NameProject.csproj".
I have tried re-runing the installation program from Xamarin and this error still occurs.
Could someone please suggest what may be causing this problem?
Thanks a lot.
the exact error:
C:\Windows\Microsoft.NET\Framework\v4.0.30319\Microsoft.Common.targets(9,9):
Error: The OutputPath property is not set for project 'helloWorld3.csproj'.
Please check to make sure that you have specified a valid combination of
Configuration and Platform for this project.
Configuration='Debug'
Platform='BPC'.
This error may also appear if some other project is trying to follow a
project-to-project reference to this project, this project has been
unloaded or is not included in the solution, and the referencing project
does not build using the same or an equivalent Configuration or Platform.
(helloWorld3)
I think we've seen this before. Your system manufacturer installed an environment variable called Platform onto your system. This breaks all msbuild based stuff, since msbuild automatically imports that as $(Platform), conflicting with the real $(Platform) that msbuild uses to compile.
Try removing the environment variable and try again.
