Make a call using action_call intent on Android 10 doesn't work

This works on the previous version of android but on android 10 it no longer works . any ideas how to solve this problem. any help would be greatly appreciated . I have tried with intent action_call and placeCall from telecomManager.

        /**
* Call a given number
*
* @param context
* @param number
*/
public static void call(@NotNull Context context, @NotNull String number) {
try {
// Create call intent
Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + Uri.encode(number)));
// Handle sim card selection
//            int simCard = getSimSelection(context);
//            Timber.d("simcard "+simCard);
//            if (simCard != -1) callIntent.putExtra("com.android.phone.extra.slot", simCard);
callIntent.setFlags(FLAG_ACTIVITY_NEW_TASK);
// Start the call
context.startActivity(callIntent);
} catch (SecurityException e) {
Toast.makeText(context, "Couldn't make a call due to security reasons", Toast.LENGTH_LONG).show();
} catch (NullPointerException e) {
Toast.makeText(context, "Couldnt make a call, no phone number", Toast.LENGTH_LONG).show();
}
}
/**
* Places a new outgoing call to the provided address using the system telecom service with
* the specified intent.
*
* @param activity       {@link Activity} used to start another activity for the given intent
* @param telecomManager the {@link TelecomManager} used to place a call, if possible
* @param intent         the intent for the call
*/
public static boolean placeCall(@Nullable FragmentActivity activity,
@Nullable TelecomManager telecomManager, @Nullable Intent intent) {
if (activity == null || telecomManager == null || intent == null) {
return false;
}
if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
return false;
}
telecomManager.placeCall(intent.getData(), intent.getExtras());
return true;
//        activity.startActivityForResult(intent, 1291);
//        return true;
}

try with adding callIntent.setFlags(FLAG_ACTIVITY_NEW_TASK);

Are you trying to start a call from a background service?

Android 10 restricted to starting activity from background. There are some exclusions for this. In my view asking for "SYSTEM_ALERT_WINDOW" permission is the easiest one.

private void RequestPermission() {
// Check if Android M or higher
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
// Show alert dialog to the user saying a separate permission is needed
// Launch the settings activity if the user prefers
Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
Uri.parse("package:" + getActivity().getPackageName()));
startActivityForResult(intent, ACTION_MANAGE_OVERLAY_PERMISSION_REQUEST_CODE);
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == ACTION_MANAGE_OVERLAY_PERMISSION_REQUEST_CODE) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!Settings.canDrawOverlays(getContext())) {
PermissionDenied();
}
else
{
//Permission Granted-System will work
}
}
}

If the account is not selected before placing a call in setting it requires you to send a account handle as an extra.

  try {
List<PhoneAccountHandle> phoneAccountHandleList = TelecomUtil.getTelecomManager(context).getCallCapablePhoneAccounts();
int simCard = getSimSelection(context);
// Create call intent
Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + Uri.encode(number)));
if (phoneAccountHandleList != null && !phoneAccountHandleList.isEmpty()) {
callIntent.putExtra(TelecomManager.EXTRA_PHONE_ACCOUNT_HANDLE, phoneAccountHandleList.get(simCard));
}
//            // Handle sim card selection
Timber.d("simcard %s", simCard);
if (simCard != -1) callIntent.putExtra("com.android.phone.extra.slot", simCard);
//            // Start the call
context.startActivity(callIntent);
} catch (SecurityException e) {
Toast.makeText(context, "Couldn't make a call due to security reasons", Toast.LENGTH_LONG).show();
} catch (NullPointerException e) {
Toast.makeText(context, "Couldnt make a call, no phone number", Toast.LENGTH_LONG).show();
