Crashes upon load if installed from VS Code

[bean5]

Expected Code builds and runs on ax6737 65n device.

Actual

• Code builds
• Code does not run -- crashes upon opening

About My Device Model Number: ax6737_65_n Android version: 7.0 Kernel version: 3.18.35 Custom build version: alps-mp-n0.mp1-V1.0.2_ax6737.65.n

There is no error message I can use to determine why it crashes.

@bean5 Try to run without debugging mode The library uses 32-bit .so files https://github.com/amorenew/alps_rfid_n6737/tree/master/android/src/main/jniLibs/armeabi-v7a While running debug mode Flutter uses 64bit mode then the crash will happen. Try to generate the APK and put it on the device manually Also in your app Gradle exclude flutter 64bit .so

//#RFID
packagingOptions {
    exclude 'lib/arm64-v8a/libflutter.so'
    exclude 'lib/arm64-v8a/libapp.so'
   }

I am using the example code. Do I need to update the gradle file in the example?

[amorenew]

Yes, but I wonder do you have a native SDK for your ALPS device

[bean5]

How do I find what SDK the device uses?

[amorenew]

@bean5 From where you got that device? is it a Chinese company? if they didn't give you native SDK for RFID ask them because it is custom hardware and maybe no RFID at all on your device. Device info either use and app like system info or maybe in About page in settings

I cannot install using VS Code. However, the following works:

flutter build apk
adb install -r build/app/outputs/apk/release/app-release.apk

[bean5]

It is from a Chinese company.

@bean5 So is it working now or you don't have RFID cards?

[bean5]

I'm going to advise adding to README. Give me a moment to create a PR.

[bean5]

No, it does not work. The app builds and starts, but it will not read the RFID cards that I have. I think we can ticket that separately.
