maybe is because ndk version lead to build failed

[ZhaoXinZhang]

It is lack file here?

[ZhaoXinZhang]

Hi I think the problem is dependencies { classpath 'com.android.tools.build:gradle:7.1.2' // classpath 'com.android.tools.build:gradle:7.3.0' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version" }

when com.android.tools.build:gradle:7.3.0 will build failed ,I change to classpath 'com.android.tools.build:gradle:7.1.2', it fix. Is that a problem?

[abdelaziz-mahdy]

Changing the Gradle version fixes the issue yes

[ZhaoXinZhang]

Same as #24 right?

[abdelaziz-mahdy]

Yes, why?

If you can provide a pr explaining it in readme, that's will be awesome

[ZhaoXinZhang]

OK,I do it .

[abdelaziz-mahdy]

please check version https://pub.dev/packages/pytorch_lite/versions/4.1.0-dev

camera code is tested on android but not tested on ios hopefully it works (will need someone to test it and report its status)

no need for ndk version now, thank you for pr but it wont be needed now
