Android SDK Platform 26 license error in Ionic 3

Question

I'm trying to run my Ionic 3 project on my Android device with ionic cordova run android --device --stacktrace, but, I've the following output:

...

Checking the license for package Android SDK Platform 26 in C:\Android\android-sdk\licenses Warning: License for package Android SDK Platform 26 not accepted.

FAILURE: Build failed with an exception.

• What went wrong: A problem occurred configuring root project 'android'.

You have not accepted the license agreements of the following SDK components: [Android SDK Platform 26]. Before building your project, you need to accept the license agreements and complete the installation of the missing components using the Android Studio SDK Manager. Alternatively, to learn how to transfer the license agreements from one workstation to another, go to http://d.android.com/r/studio-ui/export-licenses.html

Reading other questions, people suggested using the Android Studio SDK manager and installing the latest versions, because then I would be asked about the licenses and would have to accept them, so I installed Android 8.0 (Oreo) and Android API 27 which are the last available updates, however, at no time was I asked about any license and the error persisted. My device is connected to the PC (Windows 10) via the USB cable and the programmer mode is enabled along with USB debugging. What can I do to resolve this?

My SDK manager:

Update:

I already ran the command sdkmanager --licenses in the C:\Android\sdk\tools\bin and C:\Users\User\AppData\Local\Android\sdk\tools\bin folders and all the missing licenses were accepted, but the error continues.

My cordova-android version in package.json: "cordova-android": "~6.3.0" and in config.xml: <engine name="android" spec="~6.3.0" /> (already tried with 6.3.0 and 6.2.0 without success)

Following the error:

Checking the license for package Android SDK Platform 26 in C:\Android\android-sdk\licenses Warning: License for package Android SDK Platform 26 not accepted.

But I don't have the licenses folder in C:\Android\android-sdk, just in C:\Android\sdk. How I do for Ionic check for the folder where the licenses really are?

ionic info:

cli packages: (C:\Users\User\AppData\Roaming\npm\node_modules)

    @ionic/cli-utils  : 1.19.0
    ionic (Ionic CLI) : 3.19.0

global packages:

    cordova (Cordova CLI) : 7.1.0

local packages:

    @ionic/app-scripts : 3.1.0
    Cordova Platforms  : none
    Ionic Framework    : ionic-angular 3.9.2

System:

    Node : v6.11.2
    npm  : 3.10.10
    OS   : Windows 10

Environment Variables:

    ANDROID_HOME : C:\Android\android-sdk

Misc:

    backend : pro

Solution 1

Solved! Reading the information on the page http://tools.android.com/tech-docs/new-build-system/license:

...

If you have accepted the license agreements on one workstation, but wish to build your projects on a different one, you can export your licenses by copying the accepted licenses folder from the Android Sdk Home folder

...

So I just went to C:\Android\sdk and copied the licenses folder to the C:\Android\android-sdk folder which was where Ionic was searching for the licenses.

Thanks to all who have somehow tried to help.

Solution 2

In SDK folder you have to run under command prompt.

...\sdk\tools\bin

Enter this command

sdkmanager "platforms;android-26"

Solution 3

Check your cordova-android version . Try to run with the cordova-android version 6.2.3 .

if the above solution doesn't work follow this process.

1. Download android studio SDK Manager

2. Download the SDK for version 26.

Update

based on your Update you are adding the version in your package.json as follows

"cordova-android": "~6.3.0" so change this to following format as follows "cordova-android": "6.3.0" Reference to the Issue

Note if the above format doesn't work for the 6.3.0 , try the same with the 6.2.0 as follows "cordova-android": "6.2.0"

Update your node js, ionic,npm,android/ios version..

[Krsna Kishore]

@igor what is the version of the cordova-android

[Phonolog]

Following the instructions in this question solved the problem for me.

[Gandhi]

@Igor Go to your $ANDROID_HOME/tools/bin in command prompt and try executing the command - "./sdkmanager --licenses". Then accept All licenses listed there.

[Igor]

@Webruster "cordova-android": "~6.3.0"

[Igor]

@Phonolog but not for me :/

[Igor]

@Gandhi I accepted all the licenses that were missing, but the error continues.

[Gandhi]

@Igor did you had a look at the suggestions in this link - stackoverflow.com/questions/39760172/…

[Igor]

@Gandhi yes, I've tried all the suggestions and the error continues. I edited my question with some updates.

[Ikenna Anthony Okafor]

Your cordova-android version is 6.3.0 but you don't have android 23 sdk build tools installed. In your sdk manager, select android 6.0 and make sure the build tools is also selected, then accept the license and install. Should resolve the issue.

[Gandhi]

@IkennaAnthonyOkafor As per the OP's screenshot, android 26 sdk is installed which is compatible for cordova android version 6.3.0

[Igor]

Run with version 6.2.3 didn't work for me (the error continues). But I already have the SDK for version 26 (print screen in the question)

[Igor]

Tried with 6.3.0 and 6.2.0 but without success again, insisting that I didn't accept the Android SDK Platform 26 license. Added more info in question update.

[Gandhi]

But i guess you dint mentioned about accepting license in one workstation and building at a different one in question.

[Igor]

But I built all at the same workstation, however, the error occurred anyway

[Gandhi]

But its strange that how the licenses folder got created outside android home folder

[Hugh Barnard]

Also solves same problem for me with react-native run android. Need to supply the platform number and name that the process is complaining about, in my case "platforms;android-28".
