    I am having great difficulty getting a firemonkey programme to take piccies on an android device.

     

    This is the simplest programme I have managed to put together for this.  It keeps blowing up no matter what I try!

    (I have put 3 full days work into it, with no success, and now seek help!)


    I am using Delphi in Embarcadero® RAD Studio 10.4 Version 27.0.37889.9797
    (it will be a month before I can get home to download Sydney).

    The phone I am working on is a Huawei P20 Pro with android 10 (can I have
    android 7 back please?????)

     

    I got Marco's GitHub main form for a camera, and got the same error from it.

    I wondered if it were a Delphi bug, and sent it off to Quality.Embarcadero.
    Dave Nottage kindly replied, telling me to set the permissions.  However,
    if the permissions are not set, the error message is different, and setting
    the permissions did not help.  I sent back that Dave's considered response did
    not help any, but have heard nothing since.

     

    It is necessary to run it once, then go and set up the android settings permissions
    since android have become cripplingly paranoid from V10.

     

    The error message is:
    Project TryCamera1.spk raised exception class EJNIException with message
    'java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.res.XmlResourceParser android.content.pm.ProviderInfo.loadXmlMetaData
    (android.content.pm.PackageManager, java.lang.String)' on a null object reference'.

     

    The crash comes on ExecuteTarget in FMX.MediaLibrary.Action
    where it is called with FCameraService.TakePhoto

    TryCamera1.dpr

    TryCamera1.dproj

    TryCamera1.dproj.local

    TryCamera1.identcache

    TryCamera1.res

    TryCameraMainUnit.fmx

    TryCameraMainUnit.pas

    TryCameraMainUnit1.fmx

    TryCameraMainUnit1.pas

    @Chester Wilson If you will get java.lang.NullPointerException it is because Project Options >> Application >> Entitlement List >> Secure File Sharing is not set to true.

    Took me a while to figure it out as the documentation on that seems hidden :).

    Probably you figured this out already...
