This is a simple project that makes use of the device's vibrator. You can do the following:
1. Switch the vibrator ON for a specified duration of time (in milliseconds)
2. Switch the vibrator ON/OFF according to a specified pattern (with a repeat option included)
The library files (fiddleAround.jar and fiddleAround.xml) are in the /files folder. Copy them to your additional libraries folder and refresh the libraries in the project. Then select fiddleAround.
The Java code that was used to generate the vibration methods with:
1. Switch the vibrator ON for a specified duration of time (in milliseconds)
2. Switch the vibrator ON/OFF according to a specified pattern (with a repeat option included)
The library files (fiddleAround.jar and fiddleAround.xml) are in the /files folder. Copy them to your additional libraries folder and refresh the libraries in the project. Then select fiddleAround.
The Java code that was used to generate the vibration methods with:
B4X:
package com.johan.Vibrate;
import android.content.Context;
import android.os.Vibrator;
import anywheresoftware.b4a.BA.ShortName;
import anywheresoftware.b4a.BA.Version;
import anywheresoftware.b4a.BA;
@ShortName("B4Avibrate")
public class Vibrate
{
/**
*Vibrate with a given pattern.
*Pass in an array of Longs that are the durations for which to turn on or off the vibrator in milliseconds.
*The first value indicates the number of milliseconds to wait before turning the vibrator on. The next
*value indicates the number of milliseconds for which to keep the vibrator on before turning it off.
*Subsequent values alternate between durations in milliseconds to turn the vibrator off or to turn the vibrator on.
*Parameters:
*pattern ---> an array of longs of times for which to turn the vibrator on or off.
*repeat ---> the index into pattern at which to repeat, or -1 if you don't want to repeat.
*
*You need to add the following to the manifest file of the B4A project:
*AddPermission("android.permission.VIBRATE")
*Example:<code>
*Dim mv As Vibrate
*Dim pattern() As Long
*pattern = Array As Long(0, 100, 1000, 300, 1000, 100, 1000, 200, 1000)
*Dim repeat as Int = 0
*mv.vibratePattern(pattern, repeat)</code>
