How to program in JAVA with Tasker

[czed]

Hello,

Java programming function was added to Tasker and it's great.
My problem is that I do not understand how to program as "normal Java".
Something like :
int a=123;
return a;


Here's the code I'm interested in:

Near WiFi JAVA (188)
A1: Java Function [ Return:(WifiManager) wiman Class Or Object:CONTEXT Function:getSystemService {Object}(String) Param:wifi Param: Param: Param: Param: Param: Param: Param: Param: Param: ]
A2: Java Function [ Return:%results Class Or Object:wiman Function:getScanResults {List} () Param: Param: Param: Param: Param: Param: Param: Param: Param: Param: ]
A3: Flash [ Text:%results1 Long:Off ]


This code should return information on nearby wifis, the problem is that it does not return the SSID.
Searching I found this Java code to see the SSID object

results.get (i) .SSID;


But I have no idea how to integrate because all the codes I've seen here have only one line function.


Thank you for your help.

Here's what I do (in psuedocode), and it works for me,

I do the first two steps above exactly the same.
3) variable set %cnt to %results(#)
4) for %cntr in [1:%cnt]
5) Popup results(%cntr)
6) end for

A2: Java Function [ Return:%results Class Or Object:wiman Function:getScanResults {List} () Param: Param: Param: Param: Param: Param: Param: Param: Param: Param: ]

I have a feeling scan results may be null or zero length if there hasn't been a scan done recently.

To check that, you would need to assign the value to a Java object (e.g. results instead of %results)
and then check for null with:

If results eq null

Unfortunately, the current stable version of Tasker doesn't let you check for null. You can try the beta
posted above in the forum.

After the null check, you should check results.size() in a Java Code action to see if there are any results.

Thank you for your answer, your code will maybe help but not today .

My problem is that the results variable doesn't show SSID, it show me something like that

,capabilities: [WPA-PSK-CCMP+TKIP][WPA2-PSK-CCMP+TKIP][ESS], level: -64, frequency: 2447, timestamp: 85733819773, distance: ?(cm), distanceSd: ?(cm)

Your code will show every results one by one but my problem will be the same (no SSID)

[czed]

I've never had any null results yet.

I will try may be the beta version, but I must before create a usable code

Do you know how can I get this value with Tasker  : results.get (i) .SSID; ?

Ah, thought you weren't getting results.

To access the Java data structure, you need to store the result of the function in a Java object (no %) instead of a
Tasker variable. All Tasker variables are just strings.

So assign to 'results' instead of %results. Then you can loop through the list with a for action,
using values from results.size() and results.get( index ).

Something like:

Java Function, %listsize = results.size()
Variable Subtract, %listsize, 1
For %index 0:%listsize
  Java Function, result = results.get( %index )
  Java Function, %ssid = result.getSSID();
  Flash, Got SSID: %ssid
EndFor

Hi,

Has anyone found a solution to this, on android 4.3 or 4.4, on android 5 and above getScanResults() returns the SSID and BSSID in the List or reuslts but not 4.3 or 4.4 ?

Got It!

Hope this helps someone

Works great! I have a Samsung Galaxy S5 Android 5.0 stock phone. Tasker seems to have a problem with copy and pasting Java Function actions. I had Params that I couldn't see unless I exported to clipboard causing minor crashes. The UI for that action is a bit buggy. Build each action from scratch and you should be ok.

Dear Brad , i can not find a way to contact you but a reply on this. 

how can i run this java code in android Tasker:

ContentValues values = new ContentValues();

        values.put(Data.RAW_CONTACT_ID, 001);

        values.put(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);

        values.put(Phone.NUMBER, "1-800-GOOG-411");

        values.put(Phone.TYPE, Phone.TYPE_CUSTOM);

        values.put(Phone.LABEL, "Nirav");

        Uri dataUri = getContentResolver().insert(android.provider.ContactsContract.Data.CONTENT_URI, values);

can you please help in this ?
