Need help! Runtime Error(Invaild destinationAddress)

[pc 1304p]

Hi guys, i need some help here.

Recently i create an app call a location tracker, is a combination of "Android, where's my car" & "Broadcast Hub" but mostly the main program is "Android, where's my car". 

When i manually open the app, it will show a runtime error, which is "Invalid Destination Address" but when i used it with "SMS receiver". It doesn't have this issue as it will auto open the app itself(with trigger message).

It will attach some picture for you guys to see with the block diagram as well.

You might put a dummy address in your  TinyDB.GetValue valueIfTagNotThere  .   It is not clear from your code whether you have a valid default value for a location.  When the app is first initialized, the lat / long    takes five to 20 or more seconds to get a location from the GPS or network using the LocationSensor.

Try a dummy value and use AI2's debugger  DoIt to find out what values are being passed.

Regards,

Steve

i have been busy lately so i just saw your replied. sorry about it. anyway, may i get an example for a dummy address you're talking about? for the TinyDB.GetValue valueIfTagNotThere block. for example i put "https://www.google.com.sg" on set "global tempAddress" to call up "tinyDB1.GetValue". Cause i kinda not understand your meaning.

a dummy address is for example the value 9.145825 for lat and the value -83.763199 for long instead of using empty text blocks in Screen.Initialize

You're not "doing" anything with that do statement.

Taifun was referring to "Do It."  If you right click in the upper left corner of a block, on the drop down menu, you'll see Do it.  If you click on that (as long as the app is running in the emulator) Do It, you'll get the result of the evaluation of the block in a yellow bubble.

Test your block like that, and you'll know what your blocks make or evaluate.
