Problem running sample code "No variants found for ':app'"

[RubensOliveira97]

Hello friends,

I followed the instructions(https://developer.dji.com/mobile-sdk/documentation/quick-start/index.html) to build the sample code, but I receive this error message, and I can't advance with this because I have few experience with Android Studio, had someone this same problem ?

No variants found for ':app'.

Could you tell me the version of Android studio you are using? You can also try this tutorial:https://stackoverflow.com/questions/64366729/android-studio-no-build-variant-found-error

Thank you to answer, this is the version:

Android Studio Flamingo | 2022.2.1 Build #AI-222.4459.24.2221.9862592, built on April 1, 2023 Runtime version: 17.0.6+0-b2043.56-9586694 amd64 VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o. Windows 10 10.0 GC: G1 Young Generation, G1 Old Generation Memory: 1280M Cores: 8 Registry: external.system.auto.import.disabled=true ide.text.editor.with.preview.show.floating.toolbar=false gradle.version.catalogs.dynamic.support=true

And this is the build.gradle:

`// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript { ext.kotlin_version = '1.5.10' ext.androidXCore = "1.6.0" repositories { google() mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:4.2.2' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

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

}

allprojects { repositories { google() mavenCentral() } }

task clean(type: Delete) { delete rootProject.buildDir } `

I have the exact same problem. Could you resolve it? @RubensOliveira97

How does the Android Studio version matter? Could that really be the issue? @dji-dev

Could you send us your build.gardle file? What is the version of Android studio you are using?

Hello friends,

I followed the instructions(https://developer.dji.com/mobile-sdk/documentation/quick-start/index.html) to build the sample code, but I receive this error message, and I can't advance with this because I have few experience with Android Studio, had someone this same problem ?

No variants found for ':app'. Check build files to ensure at least one variant exists. at: ......

Maybe the the version of androidSdk in conflicted with the version of compileSdk. In my case, changing compileSdkVersion of app's build.gradle works:

android {
    compileSdkVersion 30
    buildToolsVersion '30.0.2'
    useLibrary 'org.apache.http.legacy'

    defaultConfig {
        applicationId "com.dji.sdk.sample"
        minSdkVersion 21
        targetSdkVersion 30
        ...

Take a look at William Wong's forum post about how to build the sample app https://sdk-forum.dji.net/hc/en-us/articles/5983558993433-Chapter-2-The-Sample. I'm also not sure it works in the latest version of Android Studio (Eel) I would downgrade to Chipmunk or Dolphin.

I have the same issue as well...

That's for v5, not this repo which is v4.

For me, if you look at the build issues log there's an issue with locating dx.

Following the issue here: https://stackoverflow.com/a/68430992/1799219

TLDR: Locate the d8 files and rename them to dx. On Ubuntu, it's something like this:

• /home/YourUsernameHere/Android/Sdk/build-tools/31.0.0
• /home/YourUsernameHere/Android/Sdk/build-tools/31.0.0/lib
