android - FingerprintManagerCompat method had issues with Samsung devices -


problem

java.lang.securityexception: permission denial: getcurrentuser() pid=#####, uid=##### requires android.permission.interact_across_users     @ android.os.parcel.readexception(parcel.java:1620)     @ android.os.parcel.readexception(parcel.java:1573)     @ android.hardware.fingerprint.ifingerprintservice$stub$proxy.hasenrolledfingerprints(ifingerprintservice.java:503)     @ android.hardware.fingerprint.fingerprintmanager.hasenrolledfingerprints(fingerprintmanager.java:768)     @ android.support.v4.hardware.fingerprint.fingerprintmanagercompatapi23.hasenrolledfingerprints(fingerprintmanagercompatapi23.java:39)     @ android.support.v4.hardware.fingerprint.fingerprintmanagercompat$api23fingerprintmanagercompatimpl.hasenrolledfingerprints(fingerprintmanagercompat.java:239)     @ android.support.v4.hardware.fingerprint.fingerprintmanagercompat.hasenrolledfingerprints(fingerprintmanagercompat.java:66)

this issue has occurred on samsung devices:

  • galaxy s6 active (marinelteatt)
  • galaxy on5 (on5ltemtr)
  • galaxy j7(2016) (j7eltetmo)

(data crash reports)

current solution research

after researching issue, solution i've found add following permission manifest:

<permission     android:name="android.permission.interact_across_users_full"     android:protectionlevel="signature"/>

this seems odd , i'm not sure if best or proper solution.

question

why exception being thrown? above solution correct?

i more information on this.

thanks!

i found support thread samsung mentioned firmware issue devices.

link

i added try/catch around code prevent crashes.

this should resolved in samsung firmware update.
