Azure AppCenter: Android build succeeds but no APKs found

I've been setting up Azure App Center build pipelines and after some troubleshooting, I managed to make our debug build succeed. The issue is that, it seems to not be able to find any of the generated APKs in the expected directories. Any ideas on why that is?
Here's the specific part of the output log:

I also have a post-clone bash script for generating the local.properties file which contains some secrets, and it seems to work just fine since the build uses it and goes through with it.
Sadly, I can't infer much from the logs, I'm not a DevOps engineer and have practically 0 experience in this sector.

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:

Can anyone tell me how to fix this?
Thanks for your attention.

You might miss appcompat-v7:26.1.0 in your android sdk.
Try to change to 27.+. It might help!

Android chromium full browser apk build issues

I trying to build chromium android apk with this instruction
But on GN configuration step I have following problem after arguments file editing and saving
ERROR at //build/config/android/internal_rules.gni:1966:13: Script returned non-zero exit code.

Then I try manually download google play services with command from this issue thread:
sudo ./build/android/play_services/update.py download
And get this warning:
Your version of the Google Play services library is not up to date. You might run into issues building or running the app. Please run `./build/android/play_services/update.py download` to retry downloading it.
After that I try to build full browser apk
ninja -C out/Default chrome_public_apk
and get error:
ninja: Entering directory `out/Default'
ninja: fatal: chdir to 'out/Default' - No such file or directory
Is there the way to fix this issue and build working apk file?

This works for me:
Run this command at chromium folder:
git rebase-update
gclient sync
Download google play services:
sudo ./build/android/play_services/update.py download
Configure GN: gn args opt/Full
Add this line to file: target_os="android"
Build apk with command: ninja -C opt/Full chrome_public_apk

You can try this
Go to this directory
C:\Users\Mohammad\.cordova\lib\npm_cache\cordova-android\3.6.4\package\framework
Edit project.properties file. Change target to 19.
# This file is automatically generated by Android Tools.

split.density=false
# Project target.
target=android-19
apk-configurations=
renderscript.opt.level=O0
android.library=true
Restart your terminal.

You don't have SDK correctly installed on you computer. (Path or SDK update)
It's write on your error log : You may not have the required environment or OS to build this project

you just need to install ant
sudo apt-get install ant
then do the same as before,its work correctly

Build Android project on command line on OSX: Task 'assembleDebug' not found in root project

I'm trying to build Android projects on the OSX (Mavericks 10.9.5) command line using this how-to: http://developer.android.com/tools/building/building-cmdline.html.
This How-To explains the use of assembleDebug/assembleRelease to build an Android project.
Unfortunately gradle doesn't create the assembleDebug or assembleRelease targets.
Executing ./gradlew assembleDebug returns this:
FAILURE: Build failed with an exception.
* What went wrong:
Task 'assembleDebug' not found in root project 'test'.
* Try:
Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

What am I missing to be able to build an Android project on the command line?

android create project does not create a gradle friendly structure. It creates an ant friendly structure. You have two options depending on your intentions.
use ant to build your project ( not currently supported by Android team )
use Android Studio to generate a gradle friendly project structure.
num 2 is the recommended approach by the Android team. It's as simple as dl'ing Android Studio and creating a new project. From there you should be able to create a new project that can be built with ./gradlew build

try This:
./android create project -p AppPAKTGV -a Main -k com.example.apppaktgv -t android-23 -g -v 0.11.+
it's works but when i try target 24 or 25 not work i don't now

Try to do this and note
a) you need to type tools/android under Step 3 (like step 2: Execute)
-- but as said the ant structure is not helpful
-- not sure I can go from there
b) I follow the advice and also ensure get the platform-tools
-- I can build
-- I can get that .apk
-- I can adb install (I rename any existing .apk)
Seems working!
