Error:No toolchains found in the NDK toolchains folder for ABI with prefix: arm-linux-androideabi

Question

I am REALLY new to Android Studio and I was moving to fast and removed something from my code...now I keep getting an error message & my gradle sync fails.

I see the following in the log:

2016-06-01 05:39:55,358 [32778590]   WARN - radle.project.ProjectSetUpTask -

My code basically says nothing: NOTE: AppCompatActivity is in red currently

import android.media.Image;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.ImageButton;
import android.widget.Toast;

public class HomeScreen extends AppCompatActivity {

    ImageButton musicEnable_ImageButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home_screen);

        musicEnable_ImageButton = (ImageButton) findViewById(R.id.soundEnable_button);
        musicEnable_ImageButton.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v){
                musicEnable_ImageButton.setBackgroundResource(R.drawable.musicon1);
            }
        });
    }

Answer 1

The solution for me was the following:

1. Open project in Android Studio
2. Wait for sync to finish
3. Click on File -> Project structure -> SDK Location
4. At Android NDK Location, if you don't have any NDK, install one
5. Select an existing NDK location.

That should fix it.

Answer 2

Just add this line to your local.properties in android folder: ndk.dir=/Users/apatrck03/Library/Android/sdk/ndk/23.0.7123448

whatever your ndk version is (-:

Answer 3

Installing an older NDK version (20.. or lower) from android studio seems to solve the problem. Higher versions don't solve the issue.
