Have you added the permission to your AndroidManifest?

To access the microphone this should be:

<uses-permission android:name="android.permission.RECORD_AUDIO" />

See also the AndroidManifest.xml file in our example App.

<uses-permission android:name="android.permission.RECORD_AUDIO" />

yes , i added it
permissions list like this:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.RECORD_AUDIO" /> <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.BLUETOOTH" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.READ_PHONE_STATE" /> <uses-permission android:name="android.permission.VIBRATE"/> <uses-permission android:name="android.permission.GET_TASKS"/>

The error you get the second time you request permissions indicates Android is still processing the initial request and hasn't returned an answer yet.

This makes sense because you mentioned that during the first attempt the call to the print("***********); statement is also not executed. Which should mean Dart is still awaiting the the call to the await PermissionHandler().requestPermissions([PermissionGroup.microphone]); method.

Are the permissions in de AndroidManifest.xml in the correct location? They should be a direct child of the <manifest> node.

Do you happen to see any other exceptions in you error log or console window?

yes, the location is right,

this is all log of this bug

As mentioned this error is caused because Android is still trying to verify permissions for the first attempt (hence the error message "ALREADY_REQUESTING_PERMISSIONS").

So I am wondering if you see anything in the console or error log during the first attempt. If you want to start over you can uninstall the App and start debugging it again.

i confirmed this bug exists in android platform

in my case, i check current permission status, after getting status, when i want request permission, this exception occured

Unhandled Exception: PlatformException(ERROR_ALREADY_REQUESTING_PERMISSIONS, A request for permissions is already running, please wait for it to finish before doing another request (note that you can request multiple permissions at the same time)., null)

[dianqiugg]

Normal in debug environment, no privilege prompt under release

in my case, release version is ok, your platform is android or ios

PlatformException(permission, you don't have the user permission to access the camera, null)
plz help me out

[bagus-repository]

I have this issue on v 4.0.0 with flutter 1.12.13+hotfix.5, but just on several devices

[bagus-repository]

Hey, i have the solution about this issue, i can use this package in 5.0.0 or 5.1.1 lollipop on simulator with stock rom but in real life on Coolpad with Cool UI and Oppo with Color OS, this package cause exactly that error, so the solution just use this package on SDK android < 23 (M) instead.

1. check the android manifest you are working in it must be in android -> app -> main -> android manifest and check the permission format ..
2. run flutter clean on terminal debug again
   your error will no longer will be there
