Volley Android Networking Library
(19 answers)
Closed 8 years ago.
I'm new to Android Studio and I want to use Volley library for my app but i can't add the source as a library in Android Studio.
I've searched the web but couldn't find anything. Everywhere is said to import as a library but I don't know how.
I got the volley source from git repository:
https://android.googlesource.com/platform/frameworks/volley
But I don't know how to add it to my project as a library.
UPDATE:
Volley is now official and is available through the JCenter. Here's how to import it:
implementation 'com.android.volley:volley:1.1.1'
DEPRICATED WAY:
Late to the party, but was able to import it by adding this to the build.gradle file:
dependencies {
compile 'com.mcxiaoke.volley:library:1.0.19'
}
Here is the link to unofficial Maven repo
NOTE: Volley v1.0.19 is current as of 02/05/2016. Please go to the Maven Repo (use link above), look up the latest version (line where artifactId = library) and update the version in your gradle configuration accordingly.
If you don't want to import it as a module but simply use it as a dependency you can create a jar using ant. In your volley directory just type ant jar and you will find a volley.jar in YOUR_VOLLEY_DIRECTORY/bin (you need to install apache ant if you don't have it)
You can copy the jar in the libs directory in your android app project (or create a libs directory if you don't have one) and add the dependency to build.gradle like this
compile files('libs/volley.jar')
I know this is a little later than the other 2 answers, but I couldn't get the JAR import method to work, or exporting Volley to Gradle as the latest version kept on producing errors that the Gradle version was too old...
What I did was to create a new package in my project of com.android.volley, and then copy the source code from the Volley package, making sure that you have both volley and volley/toolbox - once I did this the app ran without an issue
I'm not very good at GIT, but there must be a way to export just the package into the root of your Gradle Java source
Edit: As pointed out in the comments, this doesn't work anymore.
File -> Import Module...
Select directory where you downloaded Volley and follow all of the directions (you probably won't have to change anything, just click "Next" a bunch.)
Then, start typing your volley stuff:
private static RequestQueue queue;
As you're typing RequestQueue, it might autosuggest it, or it might turn red after you type it (I can't remember for sure). If it autosuggests it, just select it, and you're done. If it's red and underlined, press Alt-Enter, and there should be an option for something like "Add from module 'volley'" Select that, and you're done.
(Sorry if this isn't all exact. It's from memory.)

I am getting error when i want to import google-play-service in Eclipse.
i have import google-play-service-project-lib in Eclipse
i have read all possible Q&A but nothing is work.
I have it added as Library and JAR manually
Then I have tried to clean my project ...
Is there anybody who can solve this problem?
You can use this way. First of all close projects which are using google-play-services library. Whenever your mouse over the com.google.android.gms import that can not be resolved and towards the bottom of the popup menu, select the "Fix project setup" option as below. Then it'll prompt to import the google-play-services library.
Firstly, try to download latest version of Google Play Services, then:
Remove the existing library to add again manually,
Go to your java build path,
Under project tab add your library and then,
Under order & export tab tick your library,
Apply settings.
After all, just clean the project and library, it should work.
By the way, you can also check this question.
To me it was just a matter of updating the dependencies.
dependencies {
implementation 'com.google.android.gms:play-services-ads:20.6.0'
}
I concluded that if it's already on the latest version, refresh the Gradle may solve the issue - or, as already recommended by Umit Kaya, remove the existing library and add it back.
I am currently developing an Android application and I'd like to use Graphhoper 0.3 embedded in the application (I have no way of setting up a server).
I am working with Android 4.0, Eclipse Kepler, Maven 3.2.1, Android for Maven Eclipse 1.0.1.
I first tried to pull branch 0.3 and set the "core" folder up as an Eclipse project, then adding it in the Build Path of my android project. I also tried to use the graphhopper-0.3-android.jar directly.
Android Project Main Activity onStart():
GraphHopper hopper = new GraphHopper().forMobile();
Unfortunately, everytime I got the following error:
java.lang.NoClassDefFoundError: org.slf4j.LoggerFactory
It does not pop in a regular Java project; only in Android.
I've tried to add the slf4j JAR's to the build path, with no success.
Any help would be greatly appreciated! It's my first post here, and I really don't know what I could try more. If you need any more information on my setup or anything, please ask!
Edit
Complete solution in comments of the validated answer.
Because you are trying to use Graphhopper directly, the Maven is not downloading all the dependencies of the Graphhopper. In order to fix this, you should either add the Graphhopper as Maven dependency, or try to resolve the dependencies 'by hand' - i.e. by adding missing classes to the build path and exporting them to the APK (if you are using Maven, then simply add the dependencies to the pom.xml without scope tag).
I have followed the procedure as described here : Setup
I have clicked on the little 'Sync project with Gradle' button. Gradle and Android Studio seem to find everything but then I can't actually use the gms code. If I try to import, I will get autocomplete for com.google.android.gms but no further. I have updated all the packages with Android SDK Manager.
I'm running Android Studio 0.4.2.
My minSdk is set to 9
my build.gradle includes compile 'com.google.android.gms:play-services:4.0.30'
As far as the procedure is concerned I should be ready to code, but it just doesn't work. Any ideas?
[Edit, added info]
I can find the ComGoogleAndroiddGmsPlayServices3265.aar file in my exploded bundles directory. Inside of that file I also find the common directory and inside that I find the GooglePlayServicesUtil.class (which is what's not being found in my app)
I am lost.
[Edit 2]
The problem is not specific to Google Play Services OR Android Studio. I tried adding another library (HoloColorPicker) and had the same results. However, I was able to add the library's resources to my project! I was able to add them in my XML layouts and view them in my application. I was able to interact with them, they worked fine. The problem arose again when I tried to reference them in the code. Exactly like the case with gms, I had code completion when trying to import up to the point of the actual class, and I could not declare the class in the code.
I was able to use the library by cloning it and importing the project.
Also, this is not an Android Studio problem because the same thing happens on the command line with "./gradlew clean build"
This is a current bug in Android Studio: https://code.google.com/p/android/issues/detail?id=64508 to be fixed this week.
The workaround is to close the project, delete the .iml files and .idea project and re-import the project.
Keep Your compile 'com.google.android.gms:play-services:4.0.30' as very first line in build.gradle dependencies like
dependencies {
compile 'com.google.android.gms:play-services:4.0.30'
compile 'com.android.support:support-v4:18.0.+'
compile 'com.android.support:appcompat-v7:+'
}
`
Open File> Project Structure and do the following steps
Select your main module in which you want to add dependency and click on OK.
Now try to import.
I think the most important question is what you want to achieve. Not all code is under this package. Not even sure which one is.
As noted before, this is a bug with Android Studio. It just don't recognize the path for classes and shows you like if there is an error. If you try compiling you'll see that everything just work fine.
A googler recently said it'll be addressed in this week release, so, be patient and lets see whats coming.
The fact that AS is in Preview mode tell us this sort of things are going to happen :)
Android studio is crazy one, I think.
It's removed "Import module" function and you can do "New module" only.
If you are developed on Eclipse, you need export all your projects to Gradle before switch to Androids studio (WTF?)
I prefer "IntelliJ IDEA Community Edition", although It's similar Android studio but it's better than Android studio (at least until now). You just import your project as eclipse format, IntelliJ IDEA will detect dependences libraries automatic (May be you need import jar libraries by hand) and rebuild project. That Done.
I have downloaded calendar project from https://github.com/android/platform_packages_apps_calendar and now I'm trying to run that project. I imported the project to eclipse via new --> Android project from existing source, it imported successfully but I'm getting a red exclamation mark in project, like this:
When I went to properties > Android I'm seeing this:
It looks like the project is using some libraries but is not able to find in the workspace. How can I fix this?
You may to add the following dependencies as well.
https://android.googlesource.com/platform/frameworks/ex/
https://android.googlesource.com/platform/frameworks/opt/colorpicker/
https://android.googlesource.com/platform/frameworks/opt/calendar/
https://android.googlesource.com/platform/frameworks/opt/datetimepicker/
https://android.googlesource.com/platform/frameworks/opt/timezonepicker/
I was able to build the AOSP Android calendar.
Ye Lin Aung give you almost all the neccesary, but you will need also "chips" library. This library is not included in the last master aosp necessary packages , but its in their repository in the old versions.
You can find the neccesary libraries in the next repository:
https://gitlab.com/Purcallas/AOSPCalendarExtensions/tree/master
Or in the Google repository (as say Ye) you can find chips and common values:
https://android.googlesource.com/platform/frameworks/ex/+/ics-mr1
remove all the library from here and import each and every one in your project workspace and then after add the library.
Help needed!!!! Stuck for 2 weeks on this and help needed.
I've recently imported the facebook sdk for android and its projects into my workspace. It shows up errors and the problems:
Archive for required library: '/home/Documents/facebook-android-sdk-3.0.2.b/facebook/libs/._android-support-v4.jar' in project 'FacebookSDK' cannot be read or is not a valid ZIP file
And the samples get errors along the line of:
The container 'Android Dependencies' references non existing library '/home/Documents/facebook-android-sdk-3.0.2.b/facebook/bin/facebooksdk.jar'
The things I have done following the other discussions without any success are
cleaned project
set the Facebook SDK as library
looked at the build path section and added external jar consisting of facebook/libs
imported fb sdk like 20 times and into different folders.
made sure my java compiler was 1.6
HELP would be very greatly appreciated!!!!
Take the lastest version of android-support-v4.jar (in your sdk environement : sdk/extras/android/support/v4/android-support-v4.jar) and replace in your project and library project do not create conflict.
The steps to importing a library are:
Download the library
Place the library in the libs folder of the project.
Build the project
Do Not attempt to import the library using some import wizard.
I suspect either your download was corrupted, and you need to do it again, or you put the file into the wrong directly.
I think your problem is that the android.support.v4 versions are different, take the one from your project and replace the one in the Facebook sdk lib folder, it should dismiss the clash.
As per your question, I think you are not able to compile once you add the SDK to your project. Do you get an error saying unable to run as library?
If so that means you have included this as library and create your project as a library to be used further. It is a common mistake that I have seen many people do when they try to import a library to use and tick mark the checkbox is Library. This actually means you want this project to be treated as a library for future use. Just try to add the SDK and do not tick mark the checkbox and this project will run fine.
Many forums will just tell you to tick that checkbox and you will be stuck on this error for long time.
For any .jar file related issues you have to make the .jars files compatible as there hashing a problem and the two jars are not compatible with each other (a version issue).
