[1.4.3.1] Android SDK not found with Android SDK 25.3.0 or higher.

[YannLeBihan]

Hi,

Tried this today on two different machines running macOS Sierra 10.12.3 :

1. Fresh install of Meteor
2. Fresh install of Android Studio 2.3 + all possible SDK platforms
3. Create a Meteor project, cd to its directory
4. Run meteor add-platform android

Always got the same errors :

✗ Android target: Android SDK not found. Make sure that it is installed. If it is not at the default location, set the ANDROID_HOME environment variable.

✗ Gradle: Could not find gradle wrapper within Android SDK. Might need to update your Android SDK.

Here's what I tried :

1. Checked $ANDROID_HOME and $PATH after setting them like said in the Meteor Guide : both are OK;
2. Downgraded Android Studio to its previous version (2.2.3) that had been working up to yesterday : same result, even after removing all Android Studio support and pref files;
3. Ran several times meteor remove-platform android and meteor add-platform android : same errors;
4. Removed all SDK platforms from Android Studio, reinstalled just Android 5.1, then tried the same with Android 7.1.1 : ditto.

I'd like to know if others are experiencing the same issue, and if they found a solution or workaround.

Thanks in advance !

Yes same here!
Pretty much exact same scenario with me. Took the same steps as you outlined and have failed to get it working.

Meteor 1.4.3.1 uses Cordova 6.4.0 which I'm fairly sure requires Android SDK version 25 to be installed with the Android Studio SDK Manager (whereas previous versions used 24 or 23). I just updated the Guide to reflect this (see above commit) as I'm almost positive this is required. We should probably update History.md too in order to make sure this is clear, but do you mind confirming first if this fixes your issue?

If you don't have the full Android Studio, you should be able to start the SDK Manager with something like:

$ANDROID_HOME/tools/android sdk

Can you report back if this works for you and we'll get the History.md updated with that note?

[YannLeBihan]

Thank you for your answer. Meanwhile, I have installed Android SDK version 25 twice :

1. first with Android Studio's integrated tool, which led to the same errors
2. then with the standalone version I had kept from a previous SDK folder : after this second try, things started to get better, Meteor was able to build for Android again.

But as soon as I tried to bring Android Studio to the party (to build signed apks, manage virtual devices, etc.) it prompted me to upgrade some tools in that folder, including Gradle : I accepted the upgrade, which broke things again.

I then took a look into Gradle's former folder : it had been moved elsewhere - hence the Meteor/Cordova error about Gradle, I guess.

Will now try to get a stable setup by reusing a copy of this folder and not doing the faulty Gradle upgrade, to see if it is a viable workaround.

[YannLeBihan]

OK, I can now confirm that the most recent upgrades in Android Studio (SDK Tools + Gradle) break the link between Android and Meteor/Cordova, at least on the Mac : just upgrading the SDK Tools to latest version is enough to raise the errors I described in my first post, with no obvious way to fix them.

As for Gradle, Meteor tries to find it inside /tools/templates/gradle/, but the templates directory disappears after the SDK Tools upgrade.

The only workaround I found up to now is to reuse an old android-sdk-macosx folder from a previous install, to point Android Studio to that folder rather than its default SDK folder, and to refuse upgrading SDK Tools and Gradle when prompted to. This way, I can fire meteor run android, meteor run android-device and meteor build with success. Updates are done by double-clicking on android-sdk-macosx/tools/android rather than through Android Studio.

It seems to work for the moment, but I don't know if it will be useable for production very long.

An advice to those who would be willing to try this workaround : above all, keep a zipped backup of your previous SDK folder next to it before touching anything.

@YannLeBihan I'll have to revisit this because I tested Meteor 1.4.3 with Cordova 6.4.0 on macOS Sierra before we released Meteor 1.4.3.x and it worked fine.

Also, my above command for running the SDK Manager was incorrect, my apologies. It should have been:

$ANDROID_HOME/tools/android sdk

(Note tools instead of bin – I've corrected the above comment to avoid confusion by others).

In case it's any help, here's what my SDK Manager looks like:

This also seems to possibly be a trending issue right now as a search for the following returned a number of active issues, such as this one:

Could not find gradle wrapper within Android SDK. Might need to update your Android SDK.

Hope this helps until someone can look at this more!

@abernix

So I'm running Mac Os El Capitan 10.11.6.

$ANDROID_HOME/tools/android sdk

Still seems incorrect I'm afraid. It gives me...

The android command is no longer available.
For manual SDK and AVD management, please use Android Studio.
For command-line tools, use tools/bin/sdkmanager and tools/bin/avdmanager

I can run sdkmanager using that path. And made sure that I have installed all relevant packages for Android platform-25 etc. but still this happens...

Has anyone any more insight into what's happening here?

Unfortunately @YannLeBihan 's Suggested workaround of pointing to an older android-sdk-macosx directory isn't practical for me.

Solved (temporarily) by replacing the new updated 25.3.1 Android SDK Tools with version 25.2.5:

• download it from http://dl-ssl.google.com/android/repository/tools_r25.2.5-macosx.zip
• (possibly optional) uninstall Android SDK Tools 25.3.1 from the SDK Manager
• replace the tools folder from /Users/username/Library/Android/sdk with the new one

I had the same issues after this morning's update: Android Studio to ver. 2.3, Feb 24 build + sdk&co.
Meteor ver. 1.4.3.1
Mac OS Sierra 10.12.3

@loredanacirstea Yes that worked for me also.

Thanks for the workaround and the link.

I did not have to uninstall Android SDK Tools 25.3.1, I just switched out the tools folder. Feels wrong though.
