why jTelephonyManager not work any more in Android KitKat?, when you
just put the componet in the form and build the app crash in Android
KitKat.

Here, I tested the demo "AppTelephonyManagerDemo1" 

and it is working:   Android 4.3,  Android 5.01 and  Android 6.01

try it on a AppCompact proyect, maybe is some new androidx
incompatibility.

----------------------------------------------------------------------

there is a minor fix in "App.java"   [support folder...]

Code: Java  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  
@Override    public void onActivityResult(int requestCode, int
resultCode, Intent data) {        
 super.onActivityResult(requestCode, resultCode, data);  // <<-----
new code !!!    
 controls.jAppOnActivityResult(requestCode,resultCode,data);     } 
Can you test  again?

Thanks Jose, I make some test, my app continued crash when i just add
the componet with out add any code related to the componet, but in a
new empty project with appcompact it work fine on android 4+, so maybe
is some other components conflict with jTelephonyManager, i continue
make tests because i can't use jTelephonyManager in my app.

Can you get some android "ADB"  log?

Go to lazarus IDE menu:

 "Tools" ---> "[LAMW]....."  -->  "ADB Logcat" ---> "....[dump]"


PS. What about some "permission"  need  " jTelephonyManager" ?
(You can see them in app demo code ....)

Ok am go to dump the log by adb, the permission are ok because
actually change the call method via IntentManager and work good the
calling, but with this i can't approach the jTelephonyManager
functions.

googling i found this:

Finally found the problem, if you can see the Android manifest in the
previous post it have the android.permission.CALL_PHONE and this is
enough to make a call with the jTelephonyManager in Android 5+ but in
KitKat the system log say me: java.lang.SecurityException: Neither
user 10069 nor current process has
android.permission.READ_PHONE_STATE, so i add it to the manifest and
the app not crash any more, so you need the read phone state
permission in Android 4.4.2 for jTelephonyManager too, this is not
needed in modern android if you just make calls with the call phone
permission is enough.

Nice!

That's why the demo "AppTelephonyManagerDemo1"  works good!
