JAVA help please

[ktmom]

I am trying to get the first installed date for a specified package using the code at: https://android--code.blogspot.com/2017/06/android-get-app-first-install-time.html as a model.

   A1: Java Function [ 
        Return: installTime 
        Class Or Object:CONTEXT 
        Function: getPackageManager
        {PackageManager}().getPackageInfo(net.dinglisch.android.taskerm,0).firstInstallTime 
    ]

   A2: Java Function [ 
        Return: %installtime 
        Class Or Object: f 
        Function: getLong
        {long} (Object) 
        Param: installTime 
    ]


I expect a timestamp to be returned in %installtime.  A2 fails with the following error:

12.41.33/Variables doreplresult: |%installtime| -> |%installtime|

12.41.33/E Java Function: %installtime -> %installtime

12.41.33/E Java Function use app context

Can anyone help me sort this out?

Hi Rich, 

You only need the the Class and Field when you are dealing with static fields. Since firstInstallTime is a dynamic field, it can be gotten directly. See step A3 below. 

        Test

        

        Abort Existing Task

        

    A1: Java Function 

        Return: pacman 

        Class Or Object: CONTEXT 

        Function: getPackageManager

        {PackageManager} () 

        

    A2: Java Function 

        Return: pac_info 

        Class Or Object: pacman 

        Function: getPackageInfo

        {PackageInfo} (String, int) 

        Param: "net.dinglisch.android.taskerm" 

        Param: 0 

        

    A3: Java Function 

        Return: %install_time 

        Class Or Object: pac_info.firstInstallTime 

        Function: assign

        {long} () 

        

    A4: Flash 

        Text: %install_time 

        Long: Off

    A3: Java Function 

        Return: %install_time 

        Class Or Object: pac_info.firstInstallTime 

        Function: assign

        {long} () 

      

Hi Robert,

Thanks for the info... :)

Could you provide a screen shot or description of how you constructed A3 ?  I only see ( assign {object}  ()  ) and if I change it then %install_time does not get set...   

[Robert Ryan]

Sure, see attached.

You can get this directly with the App Info action if you enable the Get All Details option :)

Sure, see attached. 

Ok, got it working. It was the lowercase, uppercase, uppercase 'firstInstallTime'  that got me... Who makes up these naming structures...... ¯\_(ツ)_/¯

And because I had that wrong all the 'Function' helper would show me was 'assign {Object} ()' instead of 'assign {long} ()'

Thank you for the clarification. From the code I was copying from I do not believe I would have ever realized I could just add the '.firstInstallTime' to the 'pac_info' .

Thanks again..

Ahhh...  Yup.. That would be a bit easier... :)

I had looked at all those a while ago then forgot that option was there when I recently checked that action. 

As always -  great work João ..
