问题 I am using Kotlin coroutines in my app and have chosen firebase as my choice for database and storage. After exploring firebase I realized that all its APIs are asynchronous and the result of the asynchronous calls are returned in a callback, and getting rid of callbacks is the main reason why I am using Kotlin coroutines in my app. This is the code I have written to upload a file to firebase cloud storage but it is giving "Task is not yet complete" error. private suspend fun saveImage

问题 I need to integrate Biometric authentication using Fingerprint and Face authentication. Fingerprint authentication works perfectly but when I set only Face authentication I am getting Biometric not enrolled response from BiometricManager.from(context) method as follows, val biometricManager = BiometricManager.from(context) when(biometricManager.canAuthenticate()){ BiometricManager.BIOMETRIC_SUCCESS ->{ Log.e(TAG, "App can authenticate using biometrics.") } BiometricManager.BIOMETRIC_ERROR_NO
