I found that if I keep pressing the touch screen, the app will slow down very much. Both happened in my code and the sample app.
The same issue happened to me on Windows Mobile, but not happened on Symbian. Anybody have some clew to fix it?

I'm sure my Desire is changing change all by its self. Sometimes when you put it down it goes onto desk clock or weather. ~Presume it does not has a shake to change screen facility or anything.Maybe its just me, the screen is very sensitive.It's just done it again, picked it up and it moved off the HTC scene onto weather.
View 3 Replies View RelatedI have a pattern unlock on my Samsung Galaxy S 19000. If I want to lock my screen manually I simply press the power button briefly which works fine. I now use a skin on my phone which doesn't allow for easy access to this power button so I'm wondering if there's an app that I can use to lock my phone screen without having to press the power button. I have looked at "lock 2.0", however, it seems to be more for actually unlocking the screen.

Was wondering if you can mute the ringer quickly. Say, if the phone is ringing and you know you don't want to answer it. Or you forgot to turn off the ringer in church or something. Is there a way to just mute the ringer WITHOUT sending the caller to voice mail immediately (by pressing ignore)..
View 7 Replies View RelatedI just got the vibrant about a week ago, and so far no major issues. Still fumbling around in the apps market for the good stuff. One thing I found annoying was having to press the power/unlock button and then swiping the screen to unlock the phone every time, is there anything in the market or some setting to avoid pressing the button and just swiping the screen or possibly using the touch buttons on the front of the phone then swiping?
View 2 Replies View RelatedI'm wondering how I can choose to wake up my phone without having to do the slider everytime or at all.I work at my home office 12 hours a day and my phone is on my desk always.I use it alot and put it down, then use it some more and back down again.I'd like to conserve battery and not set it to just "screen stay" aka never timeout because that just uses so much battery with the screen on.And using that slider over and over and over well you get the point.So how can I just set it to wake up on like touching the screen or something?

View 1 Replies View RelatedI love SetCPU but I've noticed it's slow to recognize when the screen is on. My default setting is 1100/800 (on demand) and my screen off setting is 250/250 (on demand). Whenever I turn my screen on and it's been off for a little bit it's always at 250, even a minute later.What's more surprising is I'll go into the profiles, turn off the "screen off" profile, and it'll jump up to 1100. However, when I enable the profile, it goes back to 250, all while the screen is on.Any idea if this is something I can fix? I've tried making the "screen off" profile to 550/250 to shorten the gap but it didn't do anything.
View 3 Replies View RelatedWith imageview and network-thread,i am making live cam-view ,bitmap size is "360 240", after parsing network-data to bitmap. Code...
All thing is good ,i can see live-cam but, to fit image in screen like " Bitmap.createScaledBitmap(orgBitmap, width, height / 2 , true)" Seeing bitmap is getting slow , the bigger bitmap is , the more speed down finally, shut-downed.
how to fit image in screen without pain?
My application for the most part prefers to be online, I have of course added an offline mode so that it works perfectly well when not attached and then re-syncs when connected again.I do, however, have an issue with the initial start of the main activity "black screening" on me while (i assume) it is waiting on a TCP timeout.It would be nice to query and skip the download step if the network is super slow.
View 2 Replies View RelatedI want to make a tile based game for android. At the moment I am drawing each tile as a separate bitmap. I have a big for loop that reads from a string and draws different tiles depending on what character it finds to draw the level. I have allowed the user to scroll the screen using scrolling gestures. However the game is too slow. It takes a long time to update the screen after the user scrolls. I presume this is because it has to draw each tile's bitmap individually. What would be a faster way to draw the level? I was thinking I could merge all the tiles into one bitmap. But I don't know how to do this.
Anyway here is my code so you can see the problem:
package org.example.tutorial2d;
import android.app.Activity;
import android.os.Bundle;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.GestureDetector.OnGestureListener;
import org.example.tutorial2d.Panel;
public class Tutorial2D extends Activity implements OnGestureListener {
GestureDetector gestureScanner; Panel main;
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
gestureScanner = new GestureDetector(this);
//requestWindowFeature(Window.FEATURE_NO_TITLE);
main = new Panel(this); setContentView(main); }
@Override public boolean onTouchEvent(MotionEvent me) {
return gestureScanner.onTouchEvent(me); }
@Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
main.handleScroll(distanceX,distanceY); return true; }
@Override public boolean onDown(MotionEvent e) { return true;
} @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { return true;
} @Override public void onLongPress(MotionEvent e){
} @Override public void onShowPress(MotionEvent e) {
} @Override public boolean onSingleTapUp(MotionEvent e) { return true; } }
And the class that does all the work:
package org.example.tutorial2d;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.drawable.Drawable;
import android.util.Log;
import android.view.View;
import org.example.tutorial2d.Point;
public class Panel extends View {
private int scrollX = 0; private int scrollY = 0;
public Panel(Context context) { super(context);
} @Override public void onDraw(Canvas canvas) {
/*Bitmap scratch; //Drawable scratch;
//scratch = getContext().getResources().getDrawable(
// R.drawable.icon); canvas.drawColor(Color.BLACK);
//scratch.draw(canvas); int origin = 0;
scratch = BitmapFactory.decodeResource(getResources(), R.drawable.horizontal5);
canvas.drawBitmap(scratch, origin, origin, null);
int width = scratch.getWidth(); int height = scratch.getHeight();
scratch = BitmapFactory.decodeResource(getResources(), R.drawable.room4entrynesw3x3);
canvas.drawBitmap(scratch, origin + width, origin - 32, null);

I've noticed that sometimes it's horizontal (on my desk) and as I pick it up it to write a message, it's tilted (the screen appears horizontal). I usually tilt it a bit and then it comes back to vertical. (Maybe it's just slow and I am impatient) Has anyone else experienced this?Even when I type sometimes if I tilt it, it takes a second or two for the screen to "catch up" to my motion. Is this common? I know it's not a big deal but it's kind of annoying.Thoughts?
View 8 Replies View RelatedI know there are many talks of multi-touch on the Droid, and I don't doubt it's existence but does anyone else notice that the touch screen keyboard is really slow?For example, I'll try to type something really fast and it'll only catch about 60% of what I type, which makes everything gibberish. It can't keep up. Not that I type extremely fast or anything. I can also see the keys I press popping up to let me know what letter I'm pressing but it still doesn't read it at times.
View 4 Replies View RelatedI'm Running 2.2, CyanogenMod 6.0.0, using a Chevyno1 LV 1.0 ghz kernel with FRG22D.My home screens take forever to load after i do anything, from checking a text message, to reading the news on an app. It takes about 4 or 5 seconds to have all my widgets and icons load up. I'm OCing it to 1.0 ghz and it still loads slow. My phone performs fast overall except for this. I have five screens on my Launcher Pro home, and each one has just one widget. Is there anything I can do to speed it up? Can I clear any caches?
View 27 Replies View RelatedWhen I open up messaging on my home screen, it's pretty slow and choppy. I have about 10 threads open with about 3,000 txts total. I delete most pictures and animations I receive, to save memory, but I like to keep my text txts. It's slow when I scroll down through my threads, and it takes a second or two to open up a thread, regardless if it has 10 txts in it, or 2,000. Anyone else have this problem? I should add that it did not improve after the update. I wonder if I'm low on memory overall, but I have 87M free according to my advanced task killer app. I get what seems to be a glitch too, when I get a text message and it appears at the status bar at the top, sometimes it shows the same text three or four times, at random intervals. Sometimes it just shows it once, like it should?

View 1 Replies View RelatedI have a problem with my keyboard that only seems to have started since I installed the Hero firmware update (which has sped up the phone considerably).
When I first got the phone I was really impressed by the Keyboard and the speed at which I could type. But since the update it is really slow and keys on the right edge of the screen (especially delete) don't register at all sometimes.
I have calibrated the keyboard but it doesn't seem to make any difference.
I had been hearing that it may have been because of Handcent SMS but I removed it and it still moves slow. Text messaging, moving to home screen, etc. Things just move very slow. How can I fix this?

Other times all of that zips through. It's maddening About 24 megs of free storage on phone. What could it be? And the phone reboots a lot on its own also.

View 4 Replies View RelatedI've recently been getting user complaints that when they leave my app by pressing the 'Home' key, my app continues to play sounds like it is supposed to, but when they go back to the app, a new one opens, but the old one is still running in the background. I have noticed this sometimes myself too, but only recently (my app has been on the market for a while now). I've done some testing myself and noticed that when a new instance of the app is opened after pressing 'Home' then starting the app again, pressing the 'back' key will go back to the original instance of the app that was opened. This means that the original instance of the app was not killed, but a new one was just opened over it. Has anyone else experience something like this?

I need this service to be running throughout the life span of the application ie, all the activities in the application. But the service should not consume the resources after user pressed Home key or Back button. Is there any elegant way to do that other than stopping the service in onPause() method of all the activities?
