Android :: PNG Optimization On Packaging Process
Oct 28, 2009I've noticed that the PNGs of my application with some gradients effects looked terribly bad at the device (a Samsung Galaxy) and at the emulator, and I've found the following note at the documentation (http://developer.android.com/guide/topics/graphics/2d- graphics.html):
Image resources placed in res/drawable/ may be automatically optimized with lossless image compression by the aapt tool. For example, a true-color PNG that does not require more than 256 colors may be converted to an 8-bit PNG with a color palette. This will result in an image of equal quality but which requires less memory. So be aware that the image binaries placed in this directory can change during the build. If you plan on reading an image as a bit stream in order to convert it to a bitmap, put your images in the res/raw/ folder instead, where they will not be optimized."
I've tried the res/raw suggestion, but it didn't worked.
I've tried to use the image as JPEG as a workaround, but I couldn't use 9-patch.
I've uploaded a comparison between the original png and the "optimized" png that is shown on the emulator or devices: [url]
One workaround would be put the images at /assets/ and manually load and set the image on the ImageViews, but it requires a lot of code changes.
General :: Android Kernel Optimization
May 8, 2013What sections of kernel code are changed for optimization of performance.
Like we can change
1) the minimum free memory that android need to keep free.
2) Rate of clearing cache
3)Advanced LMK- where we can kill more than one process at at time when memory scarcity occurs.
4) Reducing logging.
5) In framework we can change the oom_adj value of important processes.
6) Implement Zram for kernel.
7) change the minimum and maximum no of process for AMS.
I want to know all the changes that can be made into kernel or framework code to optimize performance. I also want to know how can we implement swapcache for android kernel. What changes do i need to make in the code.
Android :: Optimization Accessing Fields Vs Methods
Nov 1, 2010I know rule #1 of optimization is: don't do it! But I figured this was an easy question, and if I start using the faster method now I can save a lot of cpu time when I'm finished.Now, the answer to my question may be "there's no difference" and that's fine with me. I just want to know.

Nov 17, 2010I have a long list to display in a listview. Let's say 200 items. This is a long list, but i can't reduce it. Now my list is slow and is not convenient for the user.I need something like a paging system: at the beginning I load 25 items. When the user reach the end I show a button, or something like it, to load other 25 items. An Iphone style solution.Is there a better way? Or what is the best solution?

Android :: Optimization Proposals For ListView With Data From Multiple Tables
Aug 18, 2010I just encountered the following situation. I have an Android app with a scenario which I guess may happen in multiple apps. It's about tagging/labeling/categorizing, call it as you want.After CommonsWare's feedback here a bit of a clarification. I'm weird about doing the second query to the DB inside the CursorAdapter, basically this would result in one query per row and I fear this will heavily impact my performance (I've still to test it on a real device with a substantial amount of data to see how much this impacts).My question therefore is on whether there are some strategies on how to avoid this given my data model or whether I have to basically "live" with that :)
View 2 Replies View RelatedAndroid :: Build Library Without Optimization In Order To Properly Debug It
Mar 12, 2009I'm trying to debug native library (in particular, libril.so). Everythig is going fine, breakpoint is being hit, I can go thru the lines of RIL_onRequestComplete() function. But when I tried to print out particular struct I got,
(gdb) print pRI $2 = <value optimized out> (gdb) print pRI->pCI $3 = (android::._115 *) 0x613 (gdb) print pRI->pCI->requestNumber Cannot access memory at address 0x613
I suspect it could be due to optimization done by compiler. But when I tried to add,
LOCAL_CFLAGS := -g3 -O0
into makefile of the lib, I've got another problem when I cannot correctly set breakpoint on desired function. Instead of correct one,
(gdb) break RIL_onRequestComplete Breakpoint 1 at 0xae402e4e: file hardware/ril/libril/ril.cpp, line 1800.
I got,
(gdb) break RIL_onRequestComplete Breakpoint 1 at 0xffffab44: file bionic/libm/src/s_tanf.c, line 42.
Does anybody know what could be a problem, and what is the right way to handle this?
Jelly Bean :: Turn Off WiFi Optimization S4 I9500 4.3
Dec 6, 2013Well I have S4 I9500 and whenever I tried to connect to my work network after updating to a clean android 4.3*OTA, I receive a notification stating that: This network has been disconnected.You need to sign-in again. This also happened to all 4.3 users in my workplace. 2 colleagues using Note 3 and another colleague using S4 19500. All of us can log onto various networks outside of our workplace like home and coffee shops. After doing some research I found out that I have to turn off wifi optimization but that option is not available in S4.

Aug 6, 2010This morning my alarm started unexpectedly at 6am. The lock screen turned into the snooze/stop screen. Dragging down didn't stop it it.. It came on every ten minutes for the next hour. My alarms were set to 9:45am and 8:30pm as usual. Even turning the phone off and on didn't stop the beeping. It was my 9:45am ringtone even. (The two are set differently)
Anyone else see anything like this? I'm on OTA 2.1

Jul 18, 2010Is there any way to change when these 3 things happen separately? Can I make it so my screen fades earlier but still takes just as long to go completely black? Is there a way to extend the time between total blackout and locking? Is there a way to turn off auto screen lock all together but keep the auto fade out and auto black out? I am always able to remember to manually lock the screen and the auto lock is annoying but I still like the power saving of the screen fade and black out.
View 3 Replies View RelatedMotorola Droid X :: Bubbles On Screen / Even When Screen Protector Removed
Oct 21, 2010So I recently got a set of screen protectors and put one on.All was well just noticed a few bubbles and so I tried to work them out.They weren't going away, so I figured I would try again so I removed it and to my astonishment the bubbles were still there. It's like they formed under the screen somehow when I put the protector on, they were absolutely not there before.There are 2 in the center of the screen and a few along the edges. At first I just thought it was a water spot but I cannot wipe them off.The ones on the edge of the screen I can"push out" to the edge to almost make them disappear.When you touch them with the pads of your fingers you can feel a slight "bump" in the screen (very minute but still there).They bubbles are easily visible when the screen is off and almost go away when the screen is on but you can still tell they are there.Is this a defect in the phone or did I cause this trying to install the protector? I didn't push down hard on the screen, just applied the protector and they appeared.

Motorola Droid : Static Screen Protector Like That Covers Whole Screen?
Nov 24, 2009I'm currently using the phantom skinz line and although I like the body protectors I think the screen protector has reduced some of the screen's clarity/sharpness. This wasn't an issue with the static protectors I got from verizon. The only reason I replaced the verizon ones is because they didn't cover the buttons along the bottom of the screen. Anyone find a static protector they like that covers the whole screen?

Feb 23, 2010So through a weird assortment of events i managed to crack the screen on my Eris. But this is the trippy part, I didnt break the glass but the touch sensors underneath. So now i am unable to use the menu or home buttons and the entire left part of my screen and more. I am unable to unlock my device in anyway that i know(menu button, the slider). Is there any other way to unlock it? I now have 11 unread texts and 4 voicemails that I desperately want to view. Oh and I know some of you won't be happy about what I'm about to say but.... I took the leap to the moto droid. I had the chance to get it on a 1 year because I didnt get insurance and I went for it. I will really miss my Eris but the keyboard lag was just killing me.
