Not Scanning Rfid Tag In Android Version 11

[Justin-roy]

I'm Using C72 Device It's Won't Working On Android 11 but working On Android 8

@Justin-roy I don't have the hardware of reader c72 as I left the company which I made this plugin for, so I can't help.
But if you have the official SDK then you can use this plugin as a guideline to build your own plugin

[Justin-roy]

Like I don't know how integrate/upgrade can u please provide link or resouces for implementation.

@Justin-roy You need to know some java background to integrate the existing SDK you have from your hardware provider

So, can i replace with latest sdk in android/libs with --> cw-deviceapi20191022 to cw-deviceapi20220607

[amorenew]

@Justin-roy I am not sure if it would work or not

[Justin-roy]

Hey please tell me how you integrate native sdk for flutter.
like step 1. create folder in libs in android/libs etc.
it's really helpful for beginners.

@Justin-roy
The first step is to clean up the existing native sample from your hardware provider.
You need to make a helper class like this file which contains all possible functions I needed
https://github.com/amorenew/uhf_c72_plugin/blob/master/android/src/main/java/com/amorenew/c72/uhf_plugin/helper/UHFHelper.java

Do you know Java?

[Justin-roy]

Yes I need this all functionality like this and yeah I know java.
this is the latest sdk for android 11 how to integrate this.

@Justin-roy After replacing the libs jars is it working for you?
If the helper is same and you replaced jars then I don't know what could be missing

[Justin-roy]

not working

[amorenew]

@Justin-roy Do you have any errors while running the project? like permission error?
And do your example still works after replacing jars on Android 8?

[amorenew]

@Justin-roy I suspect it is permissions issue, I don't have the following code in my library

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
// 先判断有没有权限
if (!Environment.isExternalStorageManager()) {
Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
intent.setData(Uri.parse("package:" + getPackageName()));
startActivityForResult(intent, 0);
finish();
}
}

[Justin-roy]

no not working in both can you please add this sdk in your plugin for android 11 support. please

[amorenew]

@Justin-roy Cleaning up this SDK and making a helper class could take me 5 hours, as I have to dig in the code and remove UI from the logic to build the helper class

[Justin-roy]

i will help in ui part please integrate sdk :D
