This is my Service.
It's a simple service which use Handler to invoke "setWallpaper()"
every 2 seconds.
[code]

public class MyService extends Service{
public IBinder onBind(Intent intent) {
return null;
}
protected static Service sv;
protected static InputStream bg01, bg02, bg03, bg04, bg05, bg06;
protected static int index=0;
protected static final int SECONDPASSED = 0x1234;
protected boolean running = false;
Thread counterThread = null;
static Handler myWallpaperHandler = new Handler(){
public void handleMessage(Message msg) {
switch (msg.what) {
case MyService.SECONDPASSED:
updateWallpaper();
break;
}
super.handleMessage(msg);
}
};
protected static void updateWallpaper(){
try {
if(index==0){
sv.setWallpaper(bg01);
}else if(index==1){
sv.setWallpaper(bg02);
}else if(index==2){
sv.setWallpaper(bg03);
}else if(index==3){
sv.setWallpaper(bg04);
}else if(index==4){
sv.setWallpaper(bg05);
}else if(index==5){
sv.setWallpaper(bg06);
}
index++;
if(index>5){
index = 0;
}
} catch (IOException e) {
e.printStackTrace();
}
}
public void onCreate(){
sv = this;
super.onCreate();
running = true;
bg01 = sv.getResources().openRawResource(R.drawable.night01w);
bg02 = sv.getResources().openRawResource(R.drawable.night02w);
bg03 = sv.getResources().openRawResource(R.drawable.night03w);
bg04 = sv.getResources().openRawResource(R.drawable.night04w);
bg05 = sv.getResources().openRawResource(R.drawable.night05w);
bg06 = sv.getResources().openRawResource(R.drawable.night06w);
this.counterThread = new Thread(new secondCountDownRunner());
this.counterThread.start();
}
public void onDestroy() {
super.onDestroy();
running = false;
counterThread.interrupt();
}
}
class secondCountDownRunner implements Runnable{
public void run() {
while(!Thread.currentThread().isInterrupted()){
Message m = new Message();
m.what = MyService.SECONDPASSED;
MyService.myWallpaperHandler.sendMessage(m);
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
}
}
}
}[/code]My problem:
The wallpaper changes for 4-5 frames, then stopped...
Solutions I've tried:
1. I tried Logging like this:
[code]if(index==0){
Log.e("BM WALLPAPER","Wallpaper set to WP1 | " +
bg01);
sv.setWallpaper(bg01);
}else if(index==1){
Log.e("BM WALLPAPER","Wallpaper set to WP2 | " +
bg02);
sv.setWallpaper(bg02);
// and so on...
[/code]And I can still see the Log message every 2 seconds (but the
wallpaper dont change anymore)
2. I tried creating the InputStream every cycle. It works. But it
greatly slow down the phone to an unacceptable level.
[code]if(index==0){
bg01 = sv.getResources().openRawResource
(R.drawable.night01w);
sv.setWallpaper(bg01);
}else if(index==1){
bg02 = sv.getResources
().openRawResource(R.drawable.night02w);
sv.setWallpaper(bg02);
// and so on...[/code]3. I've tried all of the above solutions but use
setWallpaper(Bitmap); instead. The result is even slower...
My requests to experts in this forum:
1. I wonder why my wallpaper animated for only 4-5 frames, then
stopped. (using the first code snippet posted above)
2. If anyone happen to know how to efficiently create an animated
wallpaper, please let me know.
Thank you in advance. =)
