App is not launched on Android device.

[xcoinmakers-fukuda]

I have some issues. Please help... I tried to use this library.

With iOS device(both emulator and  actual machine), it works.

But with android device(same on ), it doesn't work. App was built but couldn't be started correctly, just displayed the scan screen directly. and on the console window, Waiting for observatory port to be available... was displayed.

And I have already applied the setting about AndroidX.

I changed files like below.

• android > build.gradle

  buildscript {
  ext.kotlin_version = '1.3.20'
  ....
  
  dependencies {
      classpath 'com.android.tools.build:gradle:3.3.2'
      classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.21"
  }
  }

• android > app > build.gradle

  
  apply plugin: 'kotlin-android'

dependencies { implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.3.21" }

- android > app > src > main > AndroidManifest.xml
```xml
<uses-permission android:name="android.permission.CAMERA" />

<activity android:name="com.apptreesoftware.barcodescan.BarcodeScannerActivity"/>
