I am trying to follow a tutorial to build an Android app using Bazel as given here:
https://docs.bazel.build/versions/master/tutorial/android-app.html. The app is being built successfully with the command:
bazel build //src/main:app
However, when I try to run the app using the command bazel mobile-install //src/main:app the build is failing with the following error:
INFO: Analyzed target //src/main:app (0 packages loaded, 0 targets configured).
INFO: Found 1 target...

How to solve this issue?
It looks like bazel is using python2 (the py2 from darwin-py2-opt-exec-2B5CBBC6 from the file paths), but from concurrent import futures in incremental_install.py doesn't work in python2.
If you don't have python3 installed, try installing it and seeing if that fixes the problem.
If you do have python3 installed, then check your bazel version, older versions of bazel might be defaulting to python2.

There is a note in the Mediapipe documentation:
Note: building MediaPipe Android apps is still not possible on native Windows. Please do this in WSL instead and see the WSL setup instruction in the next section.
This implies that what you are trying to do is currently not possible, sorry. See also this issue for other people in your situation.
I am trying to make an app for object detection using tensorflow and I am following the instructions as listed in this website:
https://www.skcript.com/svr/realtime-object-and-face-detection-in-android-using-tensorflow-object-detection-api/
But I have run into build errors.
I am making an android application for detecting objects using tensorflow API and I have followed all steps as mentioned in the above link. I am using Windows 10 for coding, not any Linux distro. I tried building the app using bazel but there are build errors.
Here's the command as instructed from the above website:
bazel build -c opt //tensorflow/contrib/android:libtensorflow_inference.so --crosstool_top=//external:android/crosstool --host_crosstool_top=#bazel_tools//tools/cpp:toolchain --cpu=armeabi-v7a
After running, it starts compiling and does 1069 processes, but after reaching 1068/1069 it displays the following:
ERROR: C:/sri/sritrain/tensorflow-master/tensorflow/contrib/android/BUILD:60:1: Linking of rule '//tensorflow/contrib/android:libtensorflow_inference.so' failed (Exit 1)
external/androidndk/ndk/toolchains/arm-linux-androideabi-4.9/prebuilt/windows-x86_64/lib/gcc/arm-linux-androideabi/4.9.x/../../../../arm-linux-androideabi/bin\ld: fatal error: bazel-out/armeabi-v7a-opt/bin/tensorflow/core/kernels/libandroid_tensorflow_kernels.lo: pread failed: Invalid argument

INFO: Elapsed time: 3148.512s, Critical Path: 443.26s
INFO: 1045 processes: 1045 local.
FAILED: Build did NOT complete successfully
I scoured through the internet and found a small modification so I typed:
bazel build -c opt //tensorflow/contrib/android:libtensorflow_inference.so --crosstool_top=//external:android/crosstool --host_crosstool_top=#bazel_tools//tools/cpp:toolchain --cpu=armeabi-v7a --cxxopt=-std=c++11
However this returns an error even before the previous command did:
ERROR: C:/sri/sritrain/tensorflow/tensorflow/contrib/android/BUILD:60:1: Linking of rule '//tensorflow/contrib/android:libtensorflow_inference.so' failed (Exit 1)

It is supposed to create a .so file on my computer but it doesn't.
I SOLVED IT!
I found the problem was that i was using the ndk-bundle from under Android Studio's folder and it was the latest ndk. I downloaded an older ndk version android_ndk_r15c and ran the command:
bazel build -c opt //tensorflow/contrib/android:libtensorflow_inference.so --crosstool_top=//external:android/crosstool --host_crosstool_top=#bazel_tools//tools/cpp:toolchain --cpu=armeabi-v7a --cxxopt=-std=c++11
So the build was completed successfully!
I'm trying to build an android application using gomobile but the commands gomobile install and gomobile build fail with gomobile: EOF . Before this error I was getting this error:
# golang.org/x/mobile/gl
In file included from /root/go/src/golang.org/x/mobile/gl/gl.go:17:0:
work.h:6:23: fatal error: GLES2/gl2.h: No such file or directory
compilation terminated. but it was fixed with yum install make gcc mesa-libGLES-devel mesa-libEGL-devel.
The application is mostly a networking application. Here are the imports. Do only certain packages work with gomobile or all of them?
"golang.org/x/mobile/app"
"golang.org/x/net/websocket"
"os/exec"
"flag"
"fmt"
log "github.com/golang/glog"
"io/ioutil"
"net"
"net/http"
"net/url"
"strconv"
OS: Fedora 22.
More info: I'm able to build https://github.com/golang/mobile/blob/master/example/network/main.go so I can only assume the issue is specific to my application.
It failed because AndroidManifest.xml was empty.
hello

i really like to bulid hybrid apps with my web knowledge
thanks.
You can try this
Go to this directory

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
I was having an error that is Camera not successful invoked on first try (click) so I tried this solution on stackoverflow Phonegap(3.0.0) Camera not successful on first try.
I followed the steps as mentioned in the answer removed android by cordova platform remove android then I run the second command cordova platform add android ;
Now when I use netbeans to run the cordova application on cordova android decvice this error occurs:

any idea about this problem?
I was having a similar issue. I ran ant debug -f "/path/to/project/build.xml" from a separate terminal. It displayed a more specific description of the error (which for me wast that there was a space in the project name). This answer also notes:
config.xml can't have a widget id with number as a first character
after a dot. For example: com.42myapp.test or com.myapp.42test won't
work as well as 42com.myapp.test. It will trigger an error from the
compiler.
I was facing similar issues when i started using the CLI to build apps using cordova and started checking the internet for solutions. While i was at it, i discovered the following things that may help you or anyone else facing the same problem can take some hints from this:
These are some very basic checks that you need to take
1. make sure you have all the required sdk's in place (ANT, Java, Android) and is available when you use these commands on the terminal/command $ ant $ java $ adt. if any of these commands are not found, then you need to get it installed or get the class paths fixed.
make sure your project path does not have spaces. i.e. do not have spaces or special characters in directory names. this issue seems to have been fixed on latest versions of cordova and phonegap, but either cases it is a good practice to follow as ant and java paths could be dependent on the folder names you make.
use -d or -v to get extra debug information on the build process to know where and what is causing the issue. $ cordova build android -d or $ cordova build android -v
Make sure you dont use "#" as the link attribute of author tag in the cordova config.xml on the root of the project. This expects the compiler to interpret a hexadecimal color and fails the build. (this was my problem)
Hope this helps.
er... Happy debugging??
Make sure your Ant is 1.8.0 or later version. Cordova 3.3 demands that.
In the past several days, I found that the conflicting files from Dropbox had a very long name. After renaming it, everything worked.
