[Amanda1995pig]

Hello, in my ionic5 Android app. I use nfc.write() sometimes succeed but sometimes fail . It alert me " instanceAttempt to invoke virtual method 'android.os.Parcelable android.content.Intent.getParcelableExtra(java.lang.String)' on a null object reference"

this is my code: -----------------------------------------start------------------------ async writeNfc(i) { this.nfc.addTagDiscoveredListener(() => { let message = this.ndef.textRecord('hello,world'); this.nfc.write([message]).then( () => { console.log('ok') }, error => { console.log(error) } ) }, (err) => { console.error(err); }).subscribe((event) => { console.log(event)

});

} --------------------------------------end----------------------------

Hope to get help,Thanks a lot
