Build android-studio app fail.

[phamminhhanhuet]

Hi, I try to build the android app.
I go to directory drishti/android-studio and edit file local.properties as:

sdk.dir=/home/user/Android/Sdk
ndk.dir=/home/user/Android/Sdk/ndk/18.1.5063045
cmake.dir=/home/user/Android/Sdk/cmake/3.10.2.4988404

Then I build project by command:
./gradlew asDebug -Parch=arm64-v8a

and got error:

The project name '../src/examples/facefilter/android-studio/app' must not contain any of the following characters: [/, , :, <, >, ", ?, *, |]. Set the 'rootProject.name' or adjust the 'include' statement.

I try find special characters in the project but there aren't.
Has anyone ever solved this case?
