Error while bazel build for 'objectdetectioncpu' for Android application

[dheeraj-2000]

Hi, I'm trying to build objectdetectioncpu application for android using bazel on Terminal, but I'm getting error while building.

Here are my system information: OS Platform and Distribution: Linux Mint 19.2 Bazel version: 3.4.1

I've tried to build using two commands, though both gives the same error: 1) Given on Mediapipe documentation' bazel build -c opt --config=android_arm64 mediapipe/examples/android/src/java/com/google/mediapipe/apps/objectdetectioncpu:objectdetectioncpu 2) Found on bazel documentation; bazel build //mediapipe/examples/android/src/java/com/google/mediapipe/apps/objectdetectioncpu:objectdetectioncpu

Here is the error log: Loading: Loading: 0 packages loaded Analyzing: target //mediapipe/examples/android/src/java/com/google/mediapipe/apps/objectdetectioncpu:objectdetectioncpu (0 packages loaded, 0 targets configured) ERROR: /home/dheeraj/my_projects/my_project_env/practice/mediapipe/mediapipe/calculators/util/BUILD:25:8: invalid character: '�' ERROR: /home/dheeraj/my_projects/my_project_env/practice/mediapipe/mediapipe/calculators/util/BUILD:25:9: invalid character: '�' ERROR: /home/dheeraj/my_projects/my_project_env/practice/mediapipe/mediapipe/calculators/util/BUILD:25:10: invalid character: '�' . . .

I've checked for the calculator which is showing as not declared in mediapipe/calculators/util, but all are declared.

How I can resolve this? Similar error is comming while building other applications too.

Not sure why you get invalid characters... Can you successfully build the hello world desktop example?

[dheeraj-2000]

@jiuqiant Yeah, I've successfully build that one.

Infact, I've successfully build and Run an android tutorial app given in bazel documtation.

Can you open the BUILD file and see if there are any special characters? What if you try the basic hello world Android app?

[RohitSingh1226]

Even I am having this same issue, is there any fix for it. And no I don't have any special characters in my build file.
