New Update

I just release an update for my first app "Show The Way". I fixed several crash problem and developed some of the features. Bulit-in direction, overlay tracing button ...

I rewrite setting activity. Now it has about, rate my app and share button. I want to get some feedback from users.

In this update, i stop using AdWhirl and i start using MoPub. In last month AdWhirl doesn't record any impression or request. But i still get ads from AdMob and inMobi. I think they stop developing on AdWhirl and focus on AdMob mediation. Whatever i decide to use MoPub and i see it is very easy to implement. It has very good mediation network system and has a good reporting with click number. With this change i start using LeadBolt and TapIt. I don't expect good result with TapIt but i want to have an alternative for AdMob.

Also i decide to develop this app's idea (save location quickly and navigate). I will release a new app which named  "Pin On Map". I will use Polaris Map Library and Sherlock Action Bar. I hope it will be available in this month.

Introduction

Android Phones have a lot of built-in sensor such as gyro, proximity and accelerometer.
Using Accelerometer in Android is a known thing. For listening sensors, class or service needs a SensorEventListener implementation. An Activity is only exists when you are seeing it. When phone enters standby mode, activity which was recently active frozen and restored whenever needed. While this frozen time, activity doesn’t run. Because of that it doesn’t need sensor updates. And Android stop to listen some sensors for power management.

Services have this condition like classes (activity). In contrast to class, a service run every time, even when phone is in standby mode. Therefore Services needs sensor updates for some situations. But android stop to listen some sensor(accelerometer) in some different phones.

There is a solution for that. This is not an exact solution but it work with a lot of phones.

With a BroadcastReceiver listenIntent.ACTION_SCREEN_OFFand register sensor listener a…

How to change position of MyLocationButton on new Map API v2? Explained

When an app use map and design some layout on this map (TextView, Button or image), developer needs to change position of default buttons of map view. (MyLocationButton, ZoomControl or compass...) As far as i know, there are two possible way for changing position of myLocationButton's position.

1- * - Disable it
    * - Create new button programmatically
    * - Add animateCamera(toCurrentLocation) to onClickListener of this button
    * - And place it wherever you want

But if you don't want to write all that there is a hack for that.

2 - * - findViewById() of hardcoded button with;
ZoomControl id =0x1MyLocation button id =0x2      * - And do whatever you want:
// Find map fragment
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);

// Find myLocationButton view
View myLocationButton = mapFragment.getView().findViewById(0x2);

if (myLocationButton != null && myLocationButton.getLayoutParams() instanceof RelativeLayout.…
