my app downloads a zip with about 350 files. A mix of JPG and HTML files. The function i wrote to do it works just fine but the unzipping takes for ever. At first i thought the reason might be that writing to the sd-card is slow. but when i unzip the same zip with an other app on my phone it works much faster. is there anything that i could do to optimize it?
here is the code:.................

View 1 Replies View RelatedI just installed the latest version of Eclipse IDE for Java Developers together with the ADT plugin on my Mac (2.8 GHz, 4 GB Ram).
- Opening new files from the package explorer.
For example, opening a layout xml file takes 1-2sec- And the mouse pointer changes.
- Switching between tabs
- Resizing views in the workspace
The performance rapidly decreases when I open more files. Are all of you developing under these circumstances? How can I speed up eclipse?
I am facing the following problem: I have a big list of street names(~2000 entries), which is stored as a variable. I have an AutoCompleteTextView which should complete the names. The process takes really long time(approx. 2 - 3 seconds) to complete the suggestion. Is there any way to speed this up? I am pasting my code, if this is necessary:The getStreetsData() method simply returns the static list of the names.
View 2 Replies View RelatedA while back I mentioned that running the imported p2p codebase I have on the emulator (on a fairly powerful laptop with plenty of mem and a fast processor) was pretty slow. I blamed all that on the codebase and in fact I was able to profile it and make it much lighter. Well still the overall app performance is slow --- and I am finding that most apps I run on the emulator are fairly slow. Is this a common trend? I do expect emulators, who are by no means a real device, to have such processing delays but are they in general this slow? Any metrics or any other feedback from anyone that depict the factor of slowdowns you would expect on an emulator vs the real device? I know a lot of this are machine dependent as well but consider an idle powerful machine. And regarding memory - I am loading Eclipse with close to 1G to be able to run the emulator and its basic services - is that normal?
View 3 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);

Just got my N1 upgraded to unlimited web use through 3. Had to set up the APN. Did that in work and looked forward to `consuming` on the train journey home.
How cheesed off was I when I got diddly squat in the way of speed and function from the network?!
Endomondo - did not work, no maps
Google maps - never registered my position
Web - realllly slow to load anything
GPS tester - only found one or 2 satellites nd never made proper contact
Anyone else got an N1 with Three? Performace pants? Any other networks just as bad?

View 24 Replies View RelatedI am running eclipse on my windows 7 machine, 6bit with 6gb ram and core 2 duo. I am currently running Eclipse 3.6 and android 2.2 SDK. I am running jdk 1.6. I am noticing that when coding and the context popups to list methods of a class, it hangs Eclipse for up to 15 seconds. This is very frustrating. One thing to note, when Eclipse hangs, my processor is maxed out, and is being worked by a java process. So its doing something whatever it is. But frequently everytime I finish an object with a period and the context box pops up, its becoming too painful to work with.

I was reading a while back someone's topic about if a microSD card can enhance the performance of HTC Hero. I'd love to look it up but I cant, this site isn't going well lately, and I'd have to reload each page 20times to get to actual topic.
View 8 Replies View RelatedI have seen some threads and articles on a few sites talking about the advantages of a better than stock mSD card for the Hero having a drastic effect on its performance. I have see others stating that a Class 4 or even Class 6 card on the Euro HTC Hero has improved performance by 400%. Now while I know "400%" is a little out there and even sounds exaggerated, I am curious what this group of people has seen or heard. Does a better MicroSD card improve overall performance?

View 3 Replies View RelatedI received my brand new SM-P605 (Galaxy Note 10.1 2014 Edition) about a week ago. I updated its firmware a couple time. Now its at PDA - P605XXUBMJ9 Everything was working perfectly fine until I put an SD Card (SanDisk Ultra microSDXC UHS-I class 10) into the tablet.
Since then, the tablet takes about two or three seconds to wake up from sleep (time from pressing the power/home button until the screen turns on). This problem goes away when I remove the SD card.
Questions:Is this normal? What I can do to make my Android 4.3 tablet wake up any faster when I am using an SD card? Should I be using a different type/kind of microSD card?

Didn't have a problem with this before on my EVO and can't recall any settings I might have changed to cause this problem but when I choose the "Disk Drive" connection for "Connect to PC" it takes a long while (minute or so) for the drive to mount. I have the default connection to "Charge Only" but when connected to my computer and I choose the "Disk Drive" option the mount is SLOW. It SEEMS to get a bit quicker if I RE-choose "Charge Only" and then go back to "Disk Drive" to mount the SD card, however, like I said above, it is MUCH SLOWER than before. I used to choose the Disk Drive option and the mount would occur RIGHT AWAY. But not it is slow.
I have installed various apps over the weeks but only recently experienced this slowness. I recall some information about USB debugging conflicting with the SD mount but that option is turned OFF on my phone. Anyone know of any apps that might be known to conflict with the SD mount?

Like I've said, I've got a bunch of apps (40?) loaded on to this card, a few documents, 4 CDs... random stuff. I haven't formatted the card in a looong time... nor have I wiped the phone in a loooong time. I am a crackflasher - I flash a new ROM every day, but I VERY RARELY have issues, so that's why I haven't wiped in so long. I would be happy to just mount the SD manually through the terminal when I need it to.
The phone is a Nexus One. I'm running a CM7.1(or whatever it is) based ROM and kernel. The SD card is the 16gig one that came with the phone.
What's the terminal command to mount the SD card to the phone? So the ROM can access it?

I currently have UD8.0 installed, but it has behaved this way with LFY and Pete's BB ROMs as well. So it doesn't seem to be a ROM related.
