Why is my command line android list targets showing nothing?

Issue

I'm running windows 10 with Android Studios installed but I'm doing all this from the command line. I downloaded the latest android sdk. then i downloaded project files from github.

I ran a build ndk-build. i assume it is successful because it took about 20 minutes or so. In a sub folder libs/mips where files were generated: liblept.so, libpng.so, and libtess.so.

Then I tried to run an android update project command like this:

C:\Program Files (x86)\Android\android-sdk\tools>android update project -p c:\tess\tess-two

I made sure that inside the tess-two folder there is AndroidManifest.xml.

I get this error message:

Error: The project either has no target set or the target is invalid.
Please provide a --target to the 'android.bat update' command.

After researching the Android Development page I ran this command :

C:\Program Files (x86)\Android\android-sdk\tools>android list targets

the result was just a single line with no lists if targets like this without an error message or anything:

Available Android targets:

How can i get the project to update as the example I'm trying to follow here suggests.

I tried solution found here "android list target" show nothing for AOSP build ...but got error message that i needed a target id before I could build an AVD.

I tried some random target IDas but they were not valid..What am i doing wrong?

Thanks for any help.

EDIT: NEW INFO Thanks for helping, I got the list by using: "android list" instead of "android target list". Must be a windows version; I just upgraded to Windows 10.

So here's what I got. The thing is how do I know which target id to use? In my AndroidManifest.xml file I see this attribute:

 <uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="20" />

I have three folders: "armeabi-v7a","mips","x860". Each folder has three files: "liblept.so","libpng.so","libtess.so". Is the list of targets that I found related to the targetSdkVersion or any of the three library files?

I'm not sure which one to use with android update project --path . --target.

Here's the list that was found:

C:\android-sdk\android-sdk-windows\platforms>android list Available Android targets: Available Android Virtual Devices:

Solution

To ensure that you have at least one target available for use, navigate to your sdk/installation/path/platforms and see if you have any version of android in there.

This is the output I get with android list targets:

I see you are building tess-two, so this is the command I used when I got to that part:

android update project --path . --target 3

Note I used . as the path because I was already in the tess-two folder and . in linux represents the current folder.
