I want to integrate some c code with Android so as first step I has to specify NDK path in Native Development node. But when I specify NDK path it gives error Invalid path for NDK
I googled but could not find some solution. Am I missing some step.
SDK and NDK are in the same folder and SDK path working fine.
Please help
I have installed
make-3.81
nawk-2007.10.23-setup
Cygwin
ADT-17.0.0
Sequoyah
android-ndk-r7b-windows.zip (Extracted)
EDIt:
I just check the link and came to know that it could be GCC absent problem .How do I check that if its GCC problem or not , or How can I check if GCC is installed or not?
Mmm... weird error. Keep in mind that in order to use the NDK, the SDK should be working in perfect way before you start with the NDK, said that, I suggest you to try the following:
1- Be sure you have the pre-requisites:
For all development platforms, GNU Make 3.81 or later is required.
Earlier versions of GNU Make might work but have not been tested.
A recent version of awk (either GNU Awk or Nawk) is also required.
For Windows, Cygwin 1.7 or higher is required. The NDK will not work
with Cygwin 1.5 installations.
2- Start from scratch again by deleting any NDK references such as the settings on eclipse, paths, folders, zips, etc.
3- Be sure you have updated to the latest Android SDK and ADT Tools. Using the Help->Check for Updates Menu in ECLIPSE and then be sure you have all the things are up to date on the Android SDK Manager.
4- I see a "D:/" on your question, so you're using a Windows PC... it must be a Windows XP (32-bit) or Vista (32- or 64-bit). Be sure to get the Windows version (http://dl.google.com/android/ndk/android-ndk-r7b-windows.zip), and when you have unzipped that ndk, rename the folder to "ndk". You can put it next to where your SDK's folder is, it should not matter.
5- Open Eclipse, and give it the path to the NDK, and see what happens.
Good luck!
I exhuasted to solve this problem "Invalid path for android SDK" but it got solved at last.
Here is how it got solved.
My system specs: P4 3.2 GHz, Windows 7 32-bit, Eclipse Standard Edition 4.3 (Kepler).
Other supporting softwares: MinGW with GNU make 3.81.
Problem (first the problem I faced and then the solution):
I downloaded Android NDK latest version from "developer.android.com/sdk/ndk/index.html" which was "android-ndk-r9-windows-x86.zip". Then I extracted it in C:\ directory then I added a ";C:\android-ndk-r9" in my PATH variable. Then I installed "Sequoyah Android Native Code Support" using eclipse "install new software" option (Help ➤ Install New Software➤type "Indigo - http://download.eclipse.org/releases/indigo" in the work with field ➤ go to Mobile and Device Development category and select Sequoyah Android Native Code Support).
Then I went to eclipse menu "Window ➤ Preferences ➤ Android ➤ Native Development" and entered "C:\android-ndk-r9" in the NDK location and got error " Invalid path for NDK".
Solution: I search exhaustively on internet and tried different solution but the solution worked for me was:
I downloaded the older version of NDK ( download link: "dl.google.com/android/ndk/android-ndk-r7c-windows.zip" ) and extracted in C:\ directory using winrar and updated the PATH in environment variable to point to the new NDK version 7c. When now I entered the path it accepted. No error appeared.
the problem is Sequoyah doesn't accept new version because it has not updated since 2011 ( I'm not sure)
Note1: for Linux users download link: "dl.google.com/android/ndk/android-ndk-r7b-darwin-x86.tar.bz2"
Note2: you can change the version in the link according to your requirement for example "dl.google.com/android/ndk/android-ndk-r4bc-windows.zip" to download version 4b.
Thanks.
Try to create a new systems variable called "NDK" and set its value to the NDK path.
Check your path to the NDK-- this has, on more than one occasion been the issue for me, at least with the SDK. (Not NDK in my instance) I know that, for instance, at the moment my NDK path is ~/android-ndk-r6/android-ndk-r6/
Also, to install gcc in windows, you must install Cygwin or such compatible gcc setup for windows. (The docs here say that it is required, but I think I may have heard of people using some slightly different implementation.) Cygwin works well for me, but you may need to specify gcc, make, and so on, in the installer as packages to be downloaded and set up on your machine, so read your installation options carefully. If you find that you have more packages that need to be installed, you can run the setup.exe program again and install them in-place.
In addition, here (at the bottom of the page) you can find an installation guide for the NDK in case you run into further issues.
Hope some file is missing in your ndk folder, so that it is unable to identify the ndk folder. Download ndk again and load it, otherwise update the native development plugin...
You said SDK and NDK are in same folder. It could be a conflict with the route. Try this:
Uninstall NDK
Reinstall NDK at D:\ecpspace\NDK\android-ndk-r7b
Create new PATH on enviroment var
Restart computer
On linux work for me, i had 2 ndks installed in different routes, and when i used eclipse, was compiling using the other one, and don't worked as i wanted.
This might sound dumb, but did you download the correct package? I had the same problem on linux until I realized I was trying to use the Windows version (I had downloaded it earlier while I was trying to install it on a different computer with cygwin). I downloaded the linux package and everything worked.
I've only been at this for a couple of days, but in my brief experience, the NDK and eclipse do not play well together. I would suggest moving to the command line for the NDK portion of the project for the time being. Some good tutorials can be found at:

I have similar bug (Eclipse Version: Indigo Service Release 2, Build id: 20120216-1857). The main problem was in Sequoya plug-in. Problem disappear when I update Sequoya to the latest version.

I'm on windows7 x64, installed today's latest stable release of android sdk studio (through android studio bundle, since it's shipped together now apparently). I have properly configured the environment variables as you'll see above.
This is what I get when issuing the following command
$ cordova build android
ANDROID_HOME=G:\installs\Android\sdk
JAVA_HOME=C:\Program Files\Java\jdk1.8.0_121
Error: Could not find gradle wrapper within Android SDK. Might need to update your Android SDK.
Looked here: G:\installs\Android\sdk\tools\templates\gradle\wrapper
And indeed, the "templates" directory doesn't even exist in my sdk install.
I've already tried the suggestions (setting the right path, uninstall/reinstall) of this question here but nothing applies to my case, and I find that manually copying and pasting packages is not really a solution, since there's a package manager in place.
If anybody has an answer as of today's android install, would be very much appreciated.
If still not working then copy all file from gradle\wrapper from Android Studio installation folder
C:\Program Files\Android\Android
Studio\plugins\android\lib\templates\gradle\wrapper
and paste it in your Android SDK gradle\wrapper then run same command.
E:\android-sdk\tools\templates\gradle\wrapper
This is a known issue; see CB-12544. For now you'll need to downgrade.
I downloaded Android SDK r25 manually and placed templates folder inside Android/sdk/tools. This solved the issue for me.
You can get it from https://dl.google.com/android/repository/tools_r25.2.3-macosx.zip
For Windows:
https://developer.android.com/studio/index.html
Go to the section :"Get just the command line tools"
There is a link 'sdk-tools-darwin-3859397.zip' for Mac, Unfortunately that didn't have the templates folder with Gradle Wrapper. So for Mac users, i will suggest not to go for this zip.
After installing Xamarin Studio I went to the options to make sure the Android SDK, JDK and NDK were all found. The first two in fact were, but the NDK was not found. It asked to specify location, and I did specify the location (when I clicked "browse" it took me to the folder where the NDK actually was). Yet, it still does not recognize it and says NDK not found at the specified location.
When using Xamarin Studio, if you are getting the error XA5101 error ("Missing Android NDK toolchains directory") you would need to download the Android NDK separately from:
http://developer.android.com/tools/sdk/ndk/index.html
Then he should unzip downloaded file and open the Xamarin IDE and go to the following menu location:
Tools ==> Options ==> SDK Locations ==> Android
Select the location of the unzipped folder.
Then close the IDE and reopen it (force close/restart if it persists in task/process manager).
Alternate to try:
Not finding NDK may also be caused because of mismatched configuration
for AVD Manager. More specifically, the Xamarin may be creating
devices & AVDs in your %USERPROFILE%.android while the
debugger/runtime emulation EXPECTS the AVDs in the ADT directory. You
can try copying ZAVD2-related files and directories into the
%USERPROFILE%.android\avd and see if that resolves the issue.
===== Initial post ======
[In case of eclipse] I think the answer is here: https://stackoverflow.com/a/11825963/918535
//goto Preference → Android → NDK and choose your ndk location
//If your NDK location is already set, the builder in the toolchain editor may be wrong. Go to project properties, C/C++ Build | Tool Chain Editor and select Android Builder as current builder.
// in your .bashsrc file, you may also need to add the env variable:
NDK_HOME=/opt/android-ndk-r8
export NDK_HOME
Okay, so I found the issue. There was no ndk-stack.exe file in my NDK location. I was thinking I would delete/uninstall everything related to NDK and reinstall. This is when I came upon ndk-build.cmd, just thought id click it since it was a cmd, and it created the ndk-stack.exe at a location on my computer which was found by both the Xamarin studio and Visual Studio( noticed later that even VS couldnt find the NDK but after the cmd, it did). Thank you for the help.
In case this catches anyone else out, I had this issue but it was because I checked "Enable AOT (Experimental)" in the Android Build Code Generation settings. This setting is off by default so probably should have left well enough alone.
Open ndk-stack.cmd with notepad to see full path of ndk-stack.exe
You can find this file in "installation-path\android-ndk\prebuilt\windows\bin\ndk-stack.exe"
my advice is to download NDK that is coherent to your version of Visual Studio, for instance, if you have VS 2015 download NDK of 2015 or 2016 year, it really helped, cause there wasn't that EXE file in NDK of 2019 version, but it was in the NDK of 2016
Change android min sdk version 4.2 or higher (API LEVEL 17+)
So, I've been trying to build a project in LibGDX for about 10 hours now. In case you'r unfamiliar, LibGDX is one of those platforms where you specify a project directory at the start, along with any required SDKs and then when you're ready to start coding it will generate a project for you.
Anyway, I've been having a problem where every time I try to build it fails with the single error message:
Execution failed for task :core:compileJava.
Could not find tools.jar
I'm guessing "tools.jar" is a package within the Android SDK, as this is the only repository needed to build, it doesn't ask for a JRE or even the Java SDK. just the Android SDK.
I have been looking in the SDK manager, I have installed all of the packages labelled "Android-SDK Tools", "Android-SDK Platform Tools" and "Android SDK Build Tools" but there is nothing else that includes "tools.jar", I am looking for some light shed on this topic as it is a very grey area. I would like to know where this .jar file comes from and what exactly it includes. Can it be installed from the Android SDK?
There have been similar questions like this before which only fit narrow situations, If someone could provide a holistic description of the tools.jar package it would benefit a great deal for me and everyone else that needs it in their 3rd-party android IDEs.
For the record, it's building with Gradle and my current SDK is well-equipped enough to build full-fledged apps in Android Studio.
Please don't answer this question with a question unless I have left out some information that is dire to finding an adequate solution
Try copying tools.jar from %JAVA_HOME\lib to Android Studio\lib
For me, copying tools.jar to Android lib folder alone didn't solve my problem.
But I also had to create a System Variable 'JAVA_HOME' in Windows Environment Variables with path to the latest JDK folder.
Restarted Android Studio, and this solved by problem.
My Android Studio Version: 4.2.1
The "tools.jar" is provided by Oracle JDK which is required by android studio for compilation - I have faced this issue after updating android studio to latest version in my PC.
To Resolve the issue follow below steps:
In Android studio File -> Project Structure -> SDKs (Under Platform Settings)
A) Add JDK path by pressing '+' symbol in middle pane if suppose JDK/JDK home path is not present in the middle pane already (Middle pane also contains the Downloaded Android SDK's)
B) Java sdk will be usually present/installed in the path
64 bit => "C:\Program Files\Java\jdk1.X.Y_ABC" (In my PC it is 1.8.0_202) or
32 bit => "C:\Program Files (x86)\Java\jdk1.X.Y_ABC"
If suppose you don't have JDK installed in your PC, please download and install from Oracle Java website
https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html
Set JDK and JRE Path(Download both from webpage mentioned in step 2) in system environment variable
A) Press windows key type "Edit the system environment variables" and open the application
B) Go to Advanced -> Environment Variables
Under system variables add JAVA_HOME and JRE_HOME as below
Set Windows system environment variable
Add jdk lib path on the Path environment variable under user variables (this step is required only if the error not resolves with the previous steps)
C:\Program Files\Java\jdk1.X.Y_ABC\lib
In my case, I have five jdk and some have tools.jar and other not, my solution is copy paste this tools.jar in all lib of jdk.
Nothing worked for me. So I Copied tools.jar and pasted it in C:\Users\UMAR_\AppData\Local\Android\Sdk\platforms\android-30 which is the path to the library for the Android API 30 Platform. I pasted tools.jar in every folder and it start working.
I didn't have tools.jar initially but followed this link and downloaded https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html
Also added to a environment variable.. but what worked was in the first para, I still don't know if adding to variable was necessary or not.
I installed Android plugin using Tools/Plugins/Settings and copied the link there, and so on. In the next step, I would get to Tools/Java Platforms/Add platform, then it pope up with "1.Choose the platform folder" instead of "1.Select platform type". Because of that, I couldn't proceed into the next steps.
I tried to remove and reinstall Java SDK and Netbeans several times using different methods. But nothing has changed. I really appreciate the answer.
Thanks
You are following one of outdated install guides/tutorials. Current version of Android support only needs to know where your Android SDK is. Go to Tools | Options | Misc | Android and set the location there. You can find more details at http://www.nbandroid.org/
It can even detect this location automatically if you open some configured project but it seems this is not your case.
After installing the plugin the sdk and the platform then choose from netbeans file new project android project next choose the target platform listed under target name input package name and voila.
Installing the platform is a seperate step. Look in the sdk folder and read the readme. On linux, at least, it says to run the "android" program, which is in the tools folder. After installing the platform through this it should let you progress in setting up netbeans.
It's not an obvious step if you're a noob and head straight to google with "setup netbeans for android"
I've installed the Android SDK and the ADT plugin, but Android doesn't show up in the Window>Preferences... dialog.
I'm running Galileo. If I go to the Installation Details part of the About Eclipse dialog, it says that I have 0.9.6 of Android DDMS and Android Development Tools. I can run adb from the command line. I tried going around the uninstall/reinstall loop once.
I'm on Windows Vista. I also have 2.7.7 of the Scala plugin installed, but I tried uninstalling that.
Any ideas on what I should try next? Thanks.
Is your eclipse installation running from the "Program Files" or "Program Files (x86)" folder?
This was my case and I had this particular problem and a few more.
What I did was to place a fresh copy of Eclipse in a different folder (e.g. c:\dev), launch it and to install the Android Plug-in using the Eclipse Update and it seems to work fine now.
I did not need to download again the Android SDK.
Sounds like you are missing a dependency. What you're describing happened to me once (I can't remember for sure, but I think it was with adt).
From http://developer.android.com/intl/de/sdk/eclipse-adt.html#installing:
Note that there are features of ADT
that require some optional Eclipse
components (for example, WST). If you
encounter an error when installing
ADT, your Eclipse installion might not
include these components. For
information about how to quickly add
the necessary components to your
Eclipse installation, see the
troubleshooting topic ADT Installation
Error: "requires plug-in
org.eclipse.wst.sse.ui".
I had the same problem. Seems to be related to where Eclipse is installed, the path should not contain spaces, like David suggested.
I installed a fresh copy of Eclipse to c:\Dev and installed the ADT. Now everything works fine.
