Nexus :: SD Card - Utilized To Speed Up System?
Jul 15, 2010
I'm sort of new to the Android OS 1.6, but i have a few questions on memory resources. 1. Can the SD card be used and utilized to speed up the android system like READYBOOST works on windows with external memory sources which utilizes a flash drive or SD card to be used like internal memory? 2.I'm having issues with apps & system programs running in the background. I know i refer to windows. but is there a way to kill startup apps like it's possible with MSConfig in windows without using a Startup Cleaner which force closes everything at boot and more times than not it freezes my androind seemingly forever?

I am an Android app developer, and I have purchased a Nexus One device which I use to continuously test my developed Android applications.
Background: ----------------- One of the applications I developed uses a native shared library (e.g. myNativeLib.so). Only my application loads & uses this native library. I had developed this app before Android NDK came out. I pack my native library into my apk's 'assets' folder, and during my application start- up, I extract this native library from my package's assets folder to my app private directory (i.e. <assets> -> /data/data/<myappprocess>/ myNativeLib.so). Then I use System.load() API in my application to dynamically load this native library.
Problem: ------------ This application was developed during Android 1.5 (i.e. cupcake) days {I didn't have the Nexus One then}. The above procedure has been working without any problems right from Android 1.5 to Android 2.2 (i.e. Froyo). I have also tested the same on my Nexus One for Android 2.1 (i.e. Eclair) and Android 2.2.
The problem began the moment I recently upgraded my Nexus One to Android 2.2.1 via the FRG83 system update. Now, whenever I try to load my native library, I get the following error:
D/dalvikvm( 3653): Trying to load lib /data/data/<myappprocess>/ <mynativelib>.so <some address> I/dalvikvm( 3653): Unable to dlopen(/data/data/<myappprocess>/ <mynativelib>.so): Cannot load library: link_image[1995]: failed to link <mynativelib>.so
What I have Tried: -------------------------- 1. I tried my application using Android 2.2 SDK (emulator)...it works, no issues. 2. I checked out the latest froyo & android2.2.1 source code from Android open-source, built & tested my application + native lib using the latest froyo source...it built & ran, no issues. This should've taken care of any changes in the native code dependencies between Android 2.2 & Android 2.2.1 3. I even checked Android 2.2.1 source code for dalvik (java System & Runtime classes) + bionic (linker & dlopen sources) between Android 2.2 & Android 2.2.1 (using source checked out from Android open-source), but couldn't find anything consequential 4. I am unable to return my Nexus One to Android 2.2.

I've been tethering my N1 with PDAnet and have been very unimpressed with the speed. I haven't done a speed test yet but it is noticeably slower than when I used to tether my Sprint BB Tour. BTW, it shows 3G and all four bars of reception. Anyone have any tips or tricks to increase the speed?

Does the Nexus One not support speed dialing or custom MP3 ringtones? I've looked all over the phone for this and can't find it.

Has anyone found a browser speed test of the HTC Incredible vs the IPhone 3Gs or the Nexus One? I would love to see how the Incredible does vs one of them. If anyone wants to make a video and post it if they have access to those devices, please feel free and do so too.

SMS Popup works on 2.2 -- but the setting to increase the speed doesn't work. The color changes work (note, they don't work on the app's own test function, you have to send yourself a text), which I love, but I had to uninstall after realizing that the speed increase doesn't work.

When you start your nexus without a SD card inserted and start the camera, what does happen? Does the camera start and you can see but can't capture, or doesn't start at all and crashes?

I have been using HTC Desire X for 1 year. Now I have bought Xperia SP, because HTC wasnt so fast (not games etc., but in normal use, long delay before app start, twitching at main screan rolling etc. ). So Xperia is faster, not as I expected, but still faster until I put my SD Card from HTC. After that Xperia bacame slow like HTC. My SD card is the expensive one Kingstom 32 GB. Is it all only because of SD card? Can you say me some info about SD cards and Android?

I 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?

My Google Nexus 7 which is running 4.2.1, at least I'm not aware of a 4.2.2 upgrade having happened, is flashing up a message "Unfortunately, System UI has stopped working"
Nothing I do can get rid of it, It won't even turn off.If your quick enough after accepting the OK option you can get it to say access the emails but you can't get any further.Its become totally useless.

Looking to speed up my Samsung Captivate a bit. Seems like every since I loaded it up with some music and movies that it is slower. Any truth in that? Considering getting an SD card to hopefully help with that but not sure if it is just my imagination. Anything else for performance tweaking would be great too.

I have a weird problem with my Nexus 1. I rooted it when I got it (some months ago), so I don't really remember all the details about how I did it, was probably some cyanogen mod thing. However back then I remember having a small issue with the "system update available" message that displays in the notification bar, when an update is available. The problem was that the message kept appearing even though the 2.2 update was successfully installed. The problem seemed to disappear at some point, but now it is back, and worse. I cannot turn on or wake up my phone without getting the annoying message in my face.
I did try to follow the instructions in the message and actually install the update and reboot (even though the phone is running 2.2), however it didn't help. So right now I am pressing the "install later" option every time I want to use the phone. Also, I found out that I can root the phone with the program Universal Androot, so I guess the solution would be to somehow unroot using the old method (that I have forgotten) and then just use the Universal Androot program whenever I want to do something that requires root. Now the reason I write all this is that I am a bit scared of bricking the thing (even though i hear it should be next to impossible).

I have a very big problem with my samsung galaxy nexus. It started 2 weeks ago when I tried to turn ON my phone, and it randomly can't Load the system (Jelly Bean 4.2.2). When I try to Turn it ON, the Nexus Picture stock up (the green red blue yellow moving image suddenly stop) and then a MATRIX like will appear on the screen (sometimes around the nexus image there will be green lines and dots. And sometimes the whole screen will have green pixels/Dots). I thought that the system is damaged, after many trials of recovering the system, I Decided to do a factory reformat/ return to factory settings.
Since I can't access the system, I unlocked the phone , installed teamwin recovery system, and did a wipe of all the things inside the internal memory (that was the most stupid decision ever) since I lost the backup system image inside the internal sd card.
I decided all of that all because that the Galaxy Nexus don't have a external SD CARD. And since I can't do a recovery of my files (because I need to be inside Android to have a DB connection to the phone). I had no option than to wipe all System, Dalvik, Cache, and Data. Now I can't flash any android system since the Clockwork and teamwin need the android image to be inside the SD CARD. And I can't send/receive any file from/to the SD card. I already tried "Nexus Root Toolkit" and "Galaxy Nexus Toolkit".
One good thing is I did install an "ICE CREAM SANDWICH image" using "Odin" (Since that was the only image I found in the internet that can be installed using Odin, but there is no luck also, when the animation is loading, the animation suddenly stop and the phone restarts.

How can I change the system default light blue color? I'd like to make it some sort of green. I'm talking about the light blue in such icons in the attached screen shots as the battery icon, the keyboard words, and the bottom bar when pulling down the notification tray. I assume it's just one setting somewhere because it's all the same blue. I am using Nova Launcher and would prefer not to root but might if necessary. I'm using the latest version of Jelly Bean on a Nexus 4

I really dont think so at all. I looked at some vids in you and that nexus is FAST!! I have my droid clocked at 550 firm all the time (its rooted) and it does not come close to how the nexus moves around and opens things up.I also know that one cannot compare speeds by simply opening things up. If that were true my wifes cliq is faster many times opening things up. But when you do things that need a strong proccesor theres where you will see the difference. For example, before I rooted the droid i could NOT stream tv shows (jetflicks) using wifi and a bluetooth stereo headset. the show would pause every 2-3 minutes, very annoying, and the voice would be of sync as well.
When I rooted the phone and installed an app that keeps the droid at 550 it worked PERFECTLY. No problems with sync or the show stopping every few minutes. SO, Im thinking that there cannot be no way in android world that the droid can perform at the same speed of the nexus when using apps that NEED a good fast proccesor.

Ok just got my EVO yesterday. This is not only my first android phone, but my first smart phone as well. I'm fairly savvy when it comes to computers and techy stuff, but I do have what sounds like a ridiculous question. I bluetoothed some files (songs and pictures) from my old phone to my EVO. It acknowledged getting them and indeed I was able to play them from the notification area after receiving them. However, now I cannot find anyplace to 'browse' the phone folders or the SD card folders so I can find and utilize these files. How do you access the SD card or the file system?

I've come over from a Window's based phone and love the Incredible, but am having a problem with pictures that I can't find an answer to in the manual.
I simply want to save all the pictures I take with the phone to the SD card so I can transfer the entire file later to dedicated photography software to be cataloged and tweaked.
I can't find how to set up the system so that every photo goes directly to the SD card by default.

Seen this error. My sd card is not readable on any android phone or computer ive tried it on.
What I think broke it was the NEW SD CARD storage optimizer by Kalyani, I opened it up after downloading off the android market and used a feature called file explorer. It took forever to read all the files on my card and eventually I closed it out before its completion and immediately noticed my sd card is now inaccesable.
Is that error fixable or should I throw out the card?
