"No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android"

[AndroidDeveloperLB]

I just wanted to try out the sample, but I got this error:

[romainguy]

It opens properly for me on several machines. Do you have an NDK properly installed and setup?

[AndroidDeveloperLB]

Isn't this enough:

?

[romainguy]

It should be. I have no idea what the problem is here, we don't even support the MIPS ABI (and it's not part of the NDK anymore I believe).

[AndroidDeveloperLB]

Is it possible that it's because I'm using Windows OS?
Or that I have AMD CPU ?

[romainguy]

Those have nothing to do with MIPS so I doubt they're related.

BTW did you follow the other instructions in the README and built the native libraries with cmake already? These are necessary before you can build the AAR.

I had the same problem (a very unexpected "No toolchains found in the NDK toolchains folder for ABI with prefix: mips64el-linux-android") when I opened an old project, and fixed it by updating some build settings:

@romainguy You are correct. I was sure it's just NDK that's needed. Seems it's a lot more.
Closing this as I don't have time for this. Sorry.
Thank you for the good work.

Find your own local android-sdk, if you download the relevant sdk of ndk, there will be a folder called "ndk-bundle"

There is a folder called "toolchains" inside.

We noticed that there are no mips64el related files inside.

The solution is as follows:

Click here to download the NDK package separately through the browser.
After unzipping, open the "toolchains" folder, compare it with the android-sdk->ndk-bundle->toolchains folder, find the missing folder, copy the past
3. Recompile, the problem is solved.
Hope it helps you mate

@romainguy Seems "mips64el-linux-android" is missing because it got deprecated:
https://issuetracker.google.com/issues/112810603
https://issuetracker.google.com/issues/112779429

https://developer.android.com/ndk/guides/abis#sa

Note: Historically the NDK supported 32-bit and 64-bit MIPS, but support was removed in NDK r17.

Please avoid using unsupported architectures.

@stark25795 The latest version doesn't have it, because of what I wrote above:

[romainguy]

That's why we don't support MIPS, because it's been deprecated/removed from the NDK

[AndroidDeveloperLB]

@romainguy So... please remove it from the sample too :)

[romainguy]

It's not in the samples.
