Import Android volley to Android Studio

问题:

I wanna use the google's volley library

I am using Android Studio and I know how to add .jar libraries.

But I could not create a .jar library with the volley files:

https://android.googlesource.com/platform/frameworks/volley

Here what I did: (using windows seven)

git clone https://android.googlesource.com/platform/frameworks/volley
cd volley
android.bat update project -p . --target android-19
ant.jar jar

And I get the output:

A java exception has occured.

what is wrong? how can i add a not .jar library?

Volley is now officially available on JCenter:

Add this line to your gradle dependencies for your Android project's app module:

compile 'com.android.volley:volley:1.0.0'

So Volley has been updated to Android studio build style which makes it harder create a jar. But the recommended way for eclipse was using it as a library project and this goes for android studio as well, but when working in android studio we call this a module. So here is a guide to how do it the way Google wants us to do it. Guide is based on this nice tutorial.

1. First get latest volley with git (git clone https://android.googlesource.com/platform/frameworks/volley).
2. In your current project (android studio) click [File] --> [New] -->[Import Module].
3. Now select the directory where you downloaded Volley to.
4. Now Android studio might guide you to do the rest but continue guide to verify that everything works correct

5. Open settings.gradle (find in root) and add (or verify this is included):

   include ':app', ':volley'

6. Now go to your build.gradle in your project and add the dependency:

   compile project(":volley")

Thats all there is to it, much simpler and easier than compiling a jar and safer than relying on third parties jars or maven uploads.

Updating Warpzit's answer for Android Studio 1.3.2 (differences in bold)
(update: appears to be the same for Android 2.0)

1. First get latest volley with git.
2. In your current project (android studio) click [file] --> [New]--> [New Module].
3. Now select [Import Gradle Project], Click Next
4. Now select the directory where you downloaded Volley to.
5. Now Android studio might guide you to do the rest but continue guide to verify that everything works correct

6. Open settings.gradle (find in root) and add (or verify this is included):

   include ':app', ':volley'

7. Now go to your build.gradle in your project and add the dependency:

   compile project(":volley")

回答4:

Way too complicated guys. Just include it in your gradle dependencies:

dependencies {
    ...
    compile 'com.mcxiaoke.volley:library:1.0.17'
}

回答5:

Most of these answers are out of date.

Google now has an easy way to import it.. We will continue to see a lot of outdated information as they did not create this solution for a good 2-3 years.

All you need to do is add to your Build.Gradle the following:

compile 'com.android.volley:volley:1.0.0'

IE

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "24.0.0"
    defaultConfig {
        applicationId "com.example.foobar.ebay"
        minSdkVersion 23
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.1.0'
    compile 'com.android.volley:volley:1.0.0'
    testCompile 'junit:junit:4.12'
}

回答6:

Add this line to the dependencies in build.gradle:

compile 'com.mcxiaoke.volley:library:1.0.+'

回答7:

After putting compile 'com.android.volley:volley:1.0.0' into your build.gradle (Module) file under dependencies, it will not work immediately, you will have to restart Android Studio first!

回答8:

Add this dependency in your gradle.build(Module:app)file

compile 'com.android.volley:volley:1.0.0'

And then sync your gradle file.

To add volley as submodule and getting regular updates from the GIT repo the following steps can be followed. Main advantage is, Volley can be customised and source code could be pull from GIT repo whenever update is required.

It is also helping for debugging purpose.

Follow the below steps :

Step I :

Add volley as submodule in Android application project GIT Repo. git submodule add -b master https://android.googlesource.com/platform/frameworks/volley Libraries/Volley

Step II :

In settings.gradle, add the following to add volley as a studio project module. include ':Volley' project(':Volley').projectDir=new File('../Libraries/Volley')

Step III :

In app/build.gradle, add following line to compile Volley compile project(':Volley')

That would be all! Volley has been successfully added in the project.

Every time you want to get the latest code from Google official Volley's repo, just run the below command

git submodule foreach git pull

The "compile project(':volley')" line was giving me this error:

Error:Execution failed for task ':volley:processDebugResources'. > com.android.ide.common.process.ProcessException: Failed to execute aapt

It was caused because the compileSdk and buildTools versions of module volley were currently on"22" and "22.0.1" and I my project was working with newer ones ("24" and "24.0.1").

SOLUTION:

Open your build.gradle (Module:volley) file and change the version of "compileSdk" and "buildTools", for example I changed this:

android {
    compileSdkVersion 22
    buildToolsVersion = '22.0.1'
}

for this:

android {
    compileSdkVersion 24
    buildToolsVersion = '24.0.1'
}

You should no longer have this error, I hope it helps:)

回答11:

Or you can simply do

ant jar

in your cloned volley git project. You should now see volley.jar in the volley projects bin folder. Copy this to you Android Studio's app\libs folder. Then add following under dependencies section of Module level build.gradle file -

compile files('libs/volley.jar')

And you should be good import and use the library classes in your project,

回答12:

In the "build.gradle" for your app, (the app, not the project), add this:

dependencies {
    ...
    implementation 'com.android.volley:volley:1.1.0'
}

回答13:

it also available on repository mavenCentral() ...

dependencies {
    // https://mvnrepository.com/artifact/com.android.volley/volley
    api "com.android.volley:volley:1.1.0'
}

回答14:

Add this in your "build.gradle" of you app.

implementation 'com.android.volley:volley:1.1.1'

回答15:

two things

one: compile is out of date rather it is better to use implementation,

and two: volley 1.0.0 is out of date and syncing project will no work

alternatively in build.gradle add implementation 'com.android.volley:volley:1.1.1' or implementation 'com.android.volley:volley:1.1.+' for 1.1.0 and newer versions.

回答16:

add volly to your studio gradle app by compile 'com.android.volley:volley:1.0.0'

回答17:

step 1:- Download volley.jar file.

step 2:- Go to your project and set the display menu from Android to Project then go to

app -> libs-> paste your volley.jar file here

step 3:- Right click on the volley.jar file and click on "add as library". and its all done.
