Best way to make an action x times without using a Handler?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I want to replace this function:
private void transmit(){
final Handler mHandler = new Handler();
Toast.makeText(this, "Wait for the connection to stablish",Toast.LENGTH_LONG).show();
mHandler.postDelayed(new Runnable() {
@Override
public void run() {
//Log.d("BtSending", "run: Sending..");
mBluetoothLeService.writeCharacteristic(superString,bluetoothGattCharacteristicHM_10);
mHandler.postDelayed(this,250);
}
},1000);
}
for something more pretty, it works just fine but a friend told me that there was a more efficient way to do it, but i dont remember what he told me. Help me please, Thanks in advance.

Handlers are the recommended way to run recurring actions in quick succession. That doesn't mean you can't make the code a bit neater, though.
private final int MSG_TRANSMIT = 100;
private TransmitHandler handler = new TransmitHandler();
private void transmit() {
//...
handler.sendInitialTransmit();
}
public class TransmitHandler extends Handler {
public TransmitHandler() {
super(Looper.getMainLooper());
}
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case MSG_TRANSMIT:
mBluetoothLeService.writeCharacteristic(superString,bluetoothGattCharacteristicHM_10);
if (shouldTransmit) sendTransmit(); //shouldTransmit is an arbitrary boolean so you can stop the loop when needed
break;
}
}
public void sendInitialTransmit() {
sendEmptyMessageAtTime(MSG_TRANSMIT, SystemClock.uptimeMillis() + 1000);
}
public void sendTransmit() {
sendEmptyMessageAtTime(MSG_TRANSMIT, SystemClock.uptimeMillis() + 250); //where 250 is your delay
}
public void cancelTransmit() {
removeMessages(MSG_TRANSMIT); //if MSG_TRANSMIT is currently queued to be executed, calling cancelTrasmit() will remove it from the queue
}
}

Do you think it could be better using a service instead?

How would you use a Service? Services are just components that can run constantly in the background. You'd still need to put something in the Service to run an action every x seconds.

Sorry I think I miss to mention a data, I need to send it every x second infinite times. But this actually answered my question haha thanks
