I report this on an extension alredy builded with appy builder editor

Rush doesn’t support annotations like DesignerComponent and UsesPermissions, instead you need to define your extension’s metadata in the metadata file – rush.yml; and Android manifest elements, like required permissions, in the AndroidManifest.xml.

This is explained in detail here

@Shreyash

How’s Rush different?

If you take a look at the generated Java file for your extension (which you can find in src → package ), you’ll find that there are no DesignerComponent and SimpleObject annotations in there. In fact, there is not a single class-level annotation. So, where did all these annotations go?

PS: You also don’t need to define the SimpleObject annotation, Rush automatically detects your extension’s Java class while compiling.

I seen solved thanks.
Great Job,Congratulation

How to add dependency ?? any example.

[Shreyash (Shreyash Saitwal)]

To add an external library (JAR) to your extension,

1. Download your desired JAR from the internet.
2. Then, copy it into the deps directory.
3. Finally, in rush.yml, add a new entry, with the exact same name of your JAR file which you copied into the deps directory, to the deps field. For example:

   deps:
     - my-library.jar
   

[MJ_BUNNY_T.V]

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
    }
}

and here the module for the app:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 22
    buildToolsVersion "22.0.0"

    defaultConfig {
        applicationId "com.ozetastudios.climbbuddy"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

like this

[Shreyash (Shreyash Saitwal)]

Sorry, I’m unable to understand what you’re trying to say. Please elaborate more instead of just pasting irrelevant stuff.

[MJ_BUNNY_T.V]

i want to know the coding how to use show us an example, an example ( my_awesome_library) file coding, what what coding we should use there.

ok i got it now

[MJ_BUNNY_T.V]

@Shreyash

Did you read this post of mine

ok i did, but geting some error

[Latest_viral (MJ Tec)]

Jar file is java zip file…similar file is AAr file… as it is an ofline builder you will have to manually implement the external library in… deps…folder…still any 1 can provide demo project or project link please provide…

[Shreyash (Shreyash Saitwal)]

@MJ_BUNNY_T.V

but geting some error

Please be a bit more specific. What error(s) do you see?

[MJ_BUNNY_T.V]

Just for testing purposes …i try wit fb sdk

[Shreyash (Shreyash Saitwal)]

Your deps field isn’t correctly indented. There should be exactly 2 spaces before - YourLibrary.jar.

PS: AAR libraries aren’t yet supported by extensions. See this post.

PS-2: Ad extensions aren’t allowed in Kodular. You can get your community as well as creator account suspended if you use and/or distribute them.

[MJ_BUNNY_T.V]

i know but as i say just for testing purpose only. And i am in just learning stage in extension.

[appmake]

[Shreyash (Shreyash Saitwal)]

Make sure you:

• are not creating (and building) your extension in the directory where you’ve unzipped rush-win64.zip,
• have JDK version 8 or above installed, and
• have JAVA_HOME path variable defined.

PS: Looking at the screenshot you posted, you seem to be creating an ad extension. Ad extensions are neither allowed nor they work in Kodular. You might get in trouble if found using and/or distributing them.

[appmake]

C:\Program Files\Java\jdk1.8.0_131\bin

[Shreyash (Shreyash Saitwal)]

The value of JAVA_HOME should be C:\Program Files\Java\jdk1.8.0_131.
