Can not get the plugin work on android sdk 29

[richard457]

here is my build.gradle file ` compileSdkVersion 29

sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}

lintOptions {
    disable 'InvalidPackage'
}

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "com.example.com"
    minSdkVersion 22
    targetSdkVersion 29
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
}`

And When I try to print I get this error Attempt to invoke virtual method 'com.example.bluetooth_print.PrinterCommand com.example.bluetooth_print.DeviceConnFactoryManager.getCurrentPrinterCommand()' on a null object reference E/AndroidRuntime(32188): at com.example.bluetooth_print.BluetoothPrintPlugin$5.run(BluetoothPrintPlugin.java:326) E/AndroidRuntime(32188): at com.example.bluetooth_print.ThreadPool$1.run(ThreadPool.java:78) E/AndroidRuntime(32188): at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1167) E/AndroidRuntime(32188): at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641) E/AndroidRuntime(32188): at java.lang.Thread.run(Thread.java:919) I/Process (32188): Sending signal. PID: 32188 SIG: 9

Note on android sdk 28 works as expected.

@thon-ju any comment here?

This a is problem for me as well. The example works for sdk28 but not sdk29. My existing app is using skd29. I would appreciate if someone can help me getting it to work for skd29. Thank you in advance. @thon-ju

Use bluetooth_thermal_printer library

I have seen this one but was wondering if I could get one that support android and ios. Thank you for the help

This seems to support it though have not tested it yet!
