How to use go-sdl2-examples\examples\android examples on Windows platform. Is how to compile SDL2 on Windows10 platform to APK file . The original README was for Linux, I don't know how to put it in Windows10. Thank you!

CMD: go run main.go is an main.exe

Hi @Suceru, I will get back to you as soon as I have access to a Windows computer as I'm currently abroad!

veeableful commented 4 years ago

Hi @Suceru! I've added instructions for Windows in the README. Could you try it and see if there's anything missing or not working?

Suceru commented 4 years ago

@veeableful Ok,thanks,According to the above method, there is no problem in compiling libexample.so. I modified:

CC=armv7a-linux-androideabi29-clang CGO_CFLAGS="-D__ANDROID_API__=29 -I${ANDROID_NDK_HOME}/sysroot/usr/include -I${ANDROID_NDK_HOME}/sysroot/usr/include/arm-linux-androideabi --sysroot=${ANDROID_SYSROOT}" CGO_LDFLAGS="-L${ANDROID_NDK_HOME}/sysroot/usr/lib -L${ANDROID_NDK_HOME}/toolchains/arm-linux-androideabi-4.9/prebuilt/windows-x86_64/lib/gcc/arm-linux-androideabi/4.9.x/ --sysroot=${ANDROID_SYSROOT}" CGO_ENABLED=1 GOOS=android GOARCH=arm go build -tags static -buildmode=c-shared -ldflags="-s -w -extldflags=-Wl,-soname,libexample.so" -o=android/libs/armeabi-v7a/libexample.so

Then, I change:

android {
compileSdkVersion 29
buildToolsVersion '29.0.3' 

defaultConfig {
    applicationId "com.example.android"
    minSdkVersion 16
    targetSdkVersion 29
    versionCode 1
    versionName '1.0'
}
...

}

But i had trouble running ./gradlew,the exported apk failed to run on Android 10. Maybe it's my problem, I will try again later.

an10 run

Hi @Suceru, is there a reason you needed to modify the build command? For me, it worked fine on my Android 10 device as it is.

Suceru commented 4 years ago

@veeableful I only downloaded the android API29 SDK on my computer, and I didn't know how to choose it, so I chose the latest installation.If it's a modification, I'll try to get back down to api16 tomorrow.

veeableful commented 4 years ago

Ahh okay. I think if you target a minimum of API 16, it would be better in the sense that it can be installed on more devices that has Android 4.1 to Android 10 (as far as I know!).

Suceru commented 4 years ago

@veeableful Okay, I know what the reason is. At first, the envirinment variables I compiled wre not set correctly. I set a %Path% less in the environment variable Path. Now it runs successfully. Thank you very much!!

veeableful commented 4 years ago

Oh that's good to hear! I'm glad you managed to get it running. And no problem :smiley:
