Hello, I am currently trying to make a livewallpaper and I keep running into crashes + images won't cylce.
MyWallpaperService.JAVA
Code:
public class MyWallpaperService extends WallpaperService
{
public void onCreate()
{
super.onCreate();
}
public void onDestroy()
{
super.onDestroy();
}
public Engine onCreateEngine()
{
return new CercleEngine();
}
class CercleEngine extends Engine
{
public Bitmap image1, image2, image3;
CercleEngine()
{
image1 = BitmapFactory.decodeResource(getResources(), R.drawable.n01);
image2 = BitmapFactory.decodeResource(getResources(), R.drawable.n02);
image3 = BitmapFactory.decodeResource(getResources(), R.drawable.n03);
}
public void onCreate(SurfaceHolder surfaceHolder)
{
super.onCreate(surfaceHolder);
}
public void onOffsetsChanged(float xOffset, float yOffset, float xStep, float yStep, int xPixels, int yPixels)
{
drawFrame();
}
void drawFrame()
{
final SurfaceHolder holder = getSurfaceHolder();
Canvas c = null;
try
{
c = holder.lockCanvas();
if (c != null)
{
c.drawBitmap(image1, 0, 0, null);
c.drawBitmap(image2, 0, 0, null);
c.drawBitmap(image3, 0, 0, null);
}
final Runnable drawRunner = new Runnable()
{
[user=439709]@override[/user]
public void run() {
drawFrame();
}
};
Handler handler = null;
handler.removeCallbacks(drawRunner);
boolean visible = true;
if (visible)
{
handler.postDelayed(drawRunner, 1); // delay 1 sec
}
} finally
{
if (c != null) holder.unlockCanvasAndPost(c);
}
}
}
}
I have no Idea what is going on, I am trying to get it to cylce these three images but it just won't. Please help???

I have been experiencing this issue for quite a while and even after googling a while, I havent found a reasonable solution for my problem.
The issue I am experiencing is that the SurfaceView I am using flickers. Once in a while, the objects I draw flicker and they change their size or colour.
It looks like that sometimes the application skips my calls to 'Paint.setColor()' and the one to 'Paint.setStrokeWidth()'.
I have made methods which change the used paint and then, in order to try to fix this issue, to set it back to the default paint values. Still the issue persists. I have also read that the problem might be due to the double buffering. Is it the case? I am using this code for the DrawingThread:
PS. u can notice that I also tried to use a dirty Rectangle to try to see if the issue can be fixed, but still nothing. [I might not have understood what it actually does.
Code:
class DrawingThread extends Thread {
private SurfaceHolder _surfaceHolder;
private CustomView _cv;
private boolean _run = false;
public DrawingThread(SurfaceHolder surfaceHolder, CustomView cv) {
super();
_surfaceHolder = surfaceHolder;
_cv = cv;
}
public void setRunning(boolean run) {
_run = run;
}
public boolean isRunning() {
return _run;
}
public SurfaceHolder getSurfaceHolder() {
return _surfaceHolder;
}
@Override
public void run() {
Canvas c;
while (_run) {
c = null;
try {
//c = _surfaceHolder.lockCanvas(new Rect(lon - range, lon + range, lat - range, lat + range));
c = _surfaceHolder.lockCanvas();
synchronized (_surfaceHolder) {
_cv.onDraw(c);
}
} finally {
if (c != null) {
_surfaceHolder.unlockCanvasAndPost(c);
}
}
}
}
}
PS. I have read somewhere I should draw on a single bitmap and then draw the bitmap on the canvas. I have tried several times but I cannot manage to do so.
Thanks in advance,
N.
Is there anyone who can help me?
Could someone give me a hand?
I cannot find the reason why I cannot fix this issue.
I have tried to draw the items on a bitmap first and then adding it to the canvas, but I didnt manage and I either get a white canvas or a completely black one.
I believe the issue is quite easy to solve after you do it once.
Not even someone who could give some suggestions?
Hey!
As far as I can see the code you posted looks fine. Can you please post the code of your CustomView class? I think there could be an issue there.
Are you trying to make a game?
Hello!!!!
Finally someone
Here is the code I use for the onDraw(canvas):
Code:
@Override
public void onDraw(Canvas canvas) {
try {
canvas.drawColor(Color.WHITE);
pt.setAntiAlias(true);
canvas.rotate(-90, 0, 0);
canvas.translate(translateX, translateY);
canvas.scale(scale, scale);
canvas.rotate(-rotation, lat, lon);
// Drawing Points
Renderer.drawStreet(gaia.getStreets(), scale, canvas, pt);
Renderer.drawPolygon(gaia.getPolygons(), canvas, pt);
Renderer.drawPOI(myContext, gaia.getPOIs(), canvas, pt, scale, rotation);
Renderer.drawCustomPOI(myContext, gaia.getCustomPOI(), canvas, pt, scale, rotation);
if (showLocation) {
drawMarker(canvas);
}
if(drivingMode)
{
Renderer.drawRoute(gaia.getRoute(), canvas, pt);
}
} catch (Exception e) {
e.printStackTrace();
}
}
This is actually a map renderer.
I know the issue is very likely to be due to the double buffering, but I cannot find a way to fix it.
Thanks!

Can you please post the code for the callback methods (onSurfaceCreated, onSurfaceChanged, onSurfaceDestroyed) and maybe the constructor for the view too? I think the problem could be due to the setting up and not the actual rendering.
How are you accessing the surfaceHolder. Are you using the getHolder() method for that? And are you sending the reference you get to the surfaceHolder from getHolder() to the DrawingThread?
Here is the light version of the code:

int sensibility = 100;
int lat;
int lon;
float translateX = -lat * scale - SCREEN_HEIGHT / 2;
float translateY = -lon * scale + SCREEN_WIDTH / 2;
boolean followLocation = true;
boolean isZooming = false;
boolean showLocation = true;
boolean followRotation = false;

Hello,
have you had the chance to check it out?
Thanks
N.
Sorry about that. I did not have access to the internet for the last 2 - 3 days.
Anyways I went through your code...If that is what you call light I wouldn't want to know whats heavy
I noticed that you have two threads which are responsible for drawing to the same view. You are using the DrawingThread to call the onDraw method of your CustomMapView object and the RenderingThread to post the invalidate method of the same CustomMapView object, which also results in a call to the onDraw method of the same view.
I am not really sure if doing this is a good thing and maybe this is what is causing the problems with the rendering? As a test, you could comment out one of the Thread.start() calls to one of the two rendering threads in your onSurfaceCreated method and check if it stops flickering.
I know this isn't how you want your app to function but if it fixes the flickering you'd know its the the two drawing threads that are causing the problem.
Code:
@Override
public void surfaceCreated(SurfaceHolder holder) {
// Comment out either one of the following two if blocks
if (!_thread.isRunning()) {
_thread.setRunning(true);
_thread.start();
}
if (!_threadStreets.isRunning()) {
_threadStreets.setRunning(true);
_threadStreets.start();
}
}
Awesome dude!
It fixed it straight away.
The reason is that I got a thread first and then added a new one, without thinking about just merging them both together
Thanks again!
Yep. You're welcome!
You'll just have to redesign your code to use just one rendering thread and it should work fine. All the best!
I am developing an application which draws the path of the user as he moves and calculates the area .
This is the code i am trying my problem is at the start of recording the path the path is drawn even if the user has not moved and sometimes when even if user is moving the path is not drawn .

mPaint.setDither(true);
mPaint.setAntiAlias(true);

This probably has to do with the accuracy of the GPS. I didn't really look at your code but maybe you should add some kind of buffer. if (movement>5m){//draw stuff}
Hi,
I´ve a big problem with the "getScanResults()" function. I always get "0" as result.
Here is my Code (it´s a service):
Code:
public void onCreate() {
super.onCreate();
wifiMgr = (WifiManager)getSystemService(Context.WIFI_SERVICE);
sharedPreferences = PreferenceManager.getDefaultSharedPreferences(this.getApplicationContext());
intentScan = new IntentFilter();
intentScan.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
scanReceiver = new ScanReceiver();
screenOnReceiver = new ScreenOnReceiver();
registerReceiver(screenOnReceiver, new IntentFilter(Intent.ACTION_SCREEN_ON));
screenOffReceiver = new ScreenOffReceiver();
registerReceiver(screenOffReceiver, new IntentFilter(Intent.ACTION_SCREEN_OFF));
}
[user=439709]@override[/user]
public void onDestroy () {
unregisterReceiver(screenOnReceiver);
unregisterReceiver(screenOffReceiver);
}
[user=439709]@override[/user]
public void onStart(Intent intent, int startId) {
wifiMgr = (WifiManager)getSystemService(Context.WIFI_SERVICE);
registerReceiver(scanReceiver, intentScan);
showToasts = sharedPreferences.getBoolean("checkbox_notification", true);
autoSync = sharedPreferences.getBoolean("checkbox_autosync", true);
if(wifiMgr.getConnectionInfo().getNetworkId() == -1) {
if(wifiMgr.setWifiEnabled(true)) {
if(!wifiMgr.startScan()){
unregisterReceiver(scanReceiver);
}
}
}else{
if(showToasts)
Toast.makeText(this.getApplicationContext(),R.string.toast_nochange, Toast.LENGTH_SHORT).show();
}
}
public class ScanReceiver extends BroadcastReceiver {
[user=439709]@override[/user]
public void onReceive(Context context, Intent intent) {
Log.d("wifi", "ScanComplete - "+intent.getAction());
List<WifiConfiguration> wifiListSupplicant = wifiMgr.getConfiguredNetworks();
List<ScanResult> wifiListScan = wifiMgr.getScanResults();
Log.d("wifi", "LIST: "+wifiListScan.size());
} }
Somebody an idea?
Thanks"
I have a problem that my monkeyboard Dab receiver needs audio in. This can be switched with the avin app. But I only need the Audio switched not the video. Is it possible to make a Task with Tasker or similar to run some code or script to switch the audio.
Because also after boot the avin app is blocking the system. For example pppwidget starts only after exiting the avin app.
I also did take a look at the code of the app but I am a completely noob at java app programming and could not identify the code for switching the audio.
Can anyone understand and help me please?
Thanks

Maybe simple shell command or something? Anyone?
I did a simple Tweak in the Avin app. Now it launches without Ui. For audio in only and only for kitkat roms.
I have a typo in the attached APK...
Hey there, sorry to disturb the old thread I need avin.apk only to show video input, and not cut audio in background for Spotify. Do you think I have a chance?
I suppose It is the direct oppossite of yours.

2nd - if you're still around - can you recompile with this ?
Might be as simple as commenting out the this.am.setParameters calls
Sorry, this is not possible for me. I did not figure it out how to disable the video.
Hello everybody
Unfortunately, I have too few post to make a thread in the " Android Software Development" forum. I would be very happy if this post can be moved to it.
I have used the Camera2 API to implement a background video recorder running as a service and recording from the front cam. For this I have created a new SurfaceView, set its size to 1x1 and moved it to the top left corner. My code is shown below. I'm using Android 5.1.
With the Camera API it worked very well but unfortunately the frame rate is only at 20 fps (and when I increase the exposure compensation it drops even more), although with the Open Camera app I have 30 fps also with increased exposure compensation. That is why I want to try Camera2 API (hoping to get higher fps). Unfortunately, I'm getting the following error:
MediaRecoder: setOutputFile called in an invalid state(2)
MediaRecorder: start called in an invalid state: 2

Here is my code:

@Override
public void onCreate() {
// Create new SurfaceView, set its size to 1x1, move it to the top left corner and set this service as a callback

surfaceView = new SurfaceView(this);
WindowManager.LayoutParams layoutParams = new WindowManager.LayoutParams(
1, 1,
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,

windowManager.addView(surfaceView, layoutParams);

Hi, were you able to get this code to work without the errors?
