Hair Segmentation on Android building Error

[munirjojoverge]

@jiuqiant
I changed directly the WORKSPACE but unfortunately I still get the same error:
ERROR: /home/munir/Documents/workspace/mediapipe-master/mediapipe/java/com/google/mediapipe/framework/BUILD:34:1: no such package '@androidsdk//com.android.support': BUILD file not found on package path and referenced by '//mediapipe/java/com/google/mediapipe/framework:android_framework_no_mff'

Any other idea

@munirjojoverge It seems that you don't setup Android SDK and NDK correctly for MediaPipe. Please follow the instructions to set $ANDROID_HOME and $ANDROID_NDK_HOME. Then, try the build command again. Let me know if it still doesn't work. Thanks.

@jiuqiant THanks for the prompt response. I did follow the setup instructions and I still get the same error:
ERROR: /home/munir/Documents/workspace/mediapipe-master/WORKSPACE:191:1: no such package '@androidsdk//': Either the path attribute of android_sdk_repository or the ANDROID_HOME environment variable must be set. and referenced by '//external:android/sdk'

At the end of my WORSPACE file (on mediapipe folder) I have

You may run setup_android.sh to install Android SDK and NDK.

android_ndk_repository(
name = "androidndk",
)

android_sdk_repository(
name = "androidsdk",
)

Could this be somehow the issue?
The other comment I have is that I have a "base" conda environment that is "sourced" automatically.
I also added on .bashrc the following lines.

export ANDROID=~/Android
export ANDROID_HOME=$ANDROID/Sdk
export ANDROID_NDK_HOME=$ANDROID_HOME/ndk-bundle

export PATH=$PATH:$ANDROID_HOME/tools
export PATH="$PATH:$HOME/bin"
source /usr/local/lib/bazel/bin/bazel-complete.bash

Seems like the conda environment hides the environment variables? It surprises me.
Another solution is to manually add the SDK and NDK path into the WORKSPACE file.

 android_ndk_repository(
     name = "androidndk",
+    path = "/path/to/Android/Sdk",
 )

 android_sdk_repository(
     name = "androidsdk",
+    path = "/path/to/Android/Ndk",
 )

Let me know if this works. Thanks.

@munirjojoverge Seems like Bazel can find your Android SDK and NDK. If the SDK can't be found, Bazel will complain that "no such package '@androidsdk//': Either the path attribute of android_sdk_repository or the ANDROID_HOME environment variable must be set. and referenced by '//external:android/sdk'".

The issue seems to be missing required packages in your Android SDK. MediaPipe needs the SDK to have the following packages:

• build-tools;28.0.3
• platform-tools
• platforms;android-28
• extras;android;m2repository

If you don't want to touch the existing SDK and NDK, please try our script to download and install the required Android SDK and NDK packages into a separate directory.

$ git checkout .
$ chmod +x setup_android_sdk_and_ndk.sh 
$./setup_android_sdk_and_ndk.sh

@munirjojoverge I went through the steps to build the Android demos with the SDK and NDK from Android Studio 3.4.2. I believe you need to download and install the following packages:

• SDK Build-Tools 28.0.3
• SDK Platform 28.6
• Android Supporting Repository

Attached are the screenshots that may help you locate those packages quickly.

@munirjojoverge, can you pull our latest version and retry the build command with Android SDK 29 and NDK 17c (or above)? Let me know if it doesn't work.
