How to increase the system volume by editing build.prop?? (system volume like key press sound,camera sound..etc) or any third party software can increase the system volume?
I check the system volume by using audio manager app..and it show my system volume already maximum... I using huawei u8950d....
I understand that userland apps on android cannot set the system clock. Wanting to know more about how the security mechanism is set up for the system I did some digging around in the source code.
/dev/alarm is opened R/W to set the system clock using SystemClock.setCurrentTimeMillis.
How the permissions work to determine whether or not an application has permission to set the clock.
I assume it's just a user level permission, and the write bit for /dev/ alarm is only enabled for the "system user" and not the "userland user" applications run under.
I've mapped my android phone as a network drive using Samba and changed the smb.conf file to show the System Root directory as well. However, system root is default set as R/O so to mange files USING my computer I need to change the permission to R/W using a file manager (such as root explorer). This is annoying, as I have to keep doing this in order to write to certail directories.
I would like the / directory (root) to be mounted as R/W as default so that I can quickly edit files on my PC without having to constantly change it to R/O. I want something that will automatically mount my phone's root dir into rw upon boot, without custom apps/having to manually mount as rw everytime it reboots.
I can't copy the file 'hosts' back to system/etc. after I cut it out of the folder a couple mins ago. When I use ES File Explorer (don't wanna pay 4euros for Root Explorer..) to try and paste it back (with everything set to RW and having root permissions) it says 'permission denied'. I don't know what I'm doing wrong..
View 3 Replies View RelatedWas getting ready to install the edited build.prop. I had renamed the old one to build.prop.bak, and somehow managed to restart the phone without putting a new one in. The phone stays at the M screen, and I can get into the standard recovery. Is there anyway I can push a new build.prop file through standard recovery? The only thing I have tried to do is reapply the 2.2 update.zip I was running, which didn't work due to signature verification failure.
View 1 Replies View RelatedIs there a way to add common system setting into the notification pull down menu?
On my old Samsung Galaxy S3, when you swipe down from the top of the screen and pull down notifications, at the top above notifications are buttons for common system settings to access (in order they are: Wi-Fi, GPS, Sound, Rotation, Bluetooth, Smart Stay, Airplane Mode, Power Saving, Hands-free mode, Screen Mirroring)
This was very useful because was easy to quickly access key functions. For example "1) swipe down and 2) press WiFi to turn on/off" or "1) swipe down and 2) press GPS to turn location on/off".
On my new Nexus 5 this functionality does not exist. When you swipe down to see notifications, key system buttons are not present. Instead there is a single system button in the upper right corner which you need to press to for common system settings (Brightness, Settings, WiFi, Mobile [ATT/Verizon], Battery, Airplane Mode, Bluetooth, Location)
This means to access common system settings requires an extra step. For example "1) swipe down, 2) press system button and 3) press WiFi to access WiFi page"
Is there a way to put these common system setting into the notification pull down menu?
Where i can find the proprietary files for android phones (htc desire gsm specifically). The wiki says "find updated prop blobs" but has no reference as to where to even look.
I want to build a KANG for a device i have no physical access to, so i cannot extract the proprietary files.
I attempted to use the new build.prop file to fix the market issue where some paid apps were not found for download.
Here is the process I used:
Download build.prop, place it on SD card. Use Root Explorer to copy build.prop into system/Deleted old build.prop file from system/ (I made a copy of the original and placed it in a folder on my SD card as a backup) Turned phone off. Turned phone back on and got to the Motorola logo, then the screen is black (backlight is still working, the screen is technically on, there just isn't anything on it).
Phone never gets to the boot animation and will not boot back up. Anyone know how I can fix this without having to flash the SBF 2.1 file again and re-root, install 2.2 update.zip, and download/setup all of my apps?
I am developing an application which can share data with email, contact and calendar application. Now I met a problem when I clear this application data or uninstall this application in the "system setting". "Setting" can only clear my own application data now.This problem is that how to clear email, contact and calendar data at the same time of clearing my application data. This problem can concluded as that how to clear several databases which have dependency at the same time.

There is a big database(15M) in my application, it is too big to download the apk if I publish the source database in myapp.apk. So I encode the db to binary files(300k). But the new problem is I should decode binary files and create the database(with data), this procedure take about several minutes, so I can NOT do this in SQLiteOpenHelper.onCreate(), this is too slow for user experience(though it is a one time procedure, it is still unacceptable).
My application has NO main activity entry in launcher, the main entry is Broadcast Receiver.on Receive, the information should display to user immediately when receiving the broadcast, so I have no chance to display a several minutes "Initializing, please waiting..." UI. The best chance to create database and init data immediately after install, but how to do this, is there any broadcast? or is there any AndroidManifest attribute?

(HTC Desire running 2.2) Sometimes the init process enters a busy loop, consuming all CPU time. This has happened to me three or four times now. When it happens, Android System Info shows 100% CPU usage and if you run top in a terminal emulator, you can see that it's the init process eating up the CPU.
This makes the phone real slow and the only cure I know of is a reboot.I was going to check out the logs while the init was looping, but I forgot. I don't know how to repeat this - today it happened when I exitted VLC Stream and Convert, but it happened before I even installed this application.
I think this happened before the 2.2 upgrade as well and my son said his Xperia X10 eats the battery real fast sometimes - so maybe the same problem exists in Android 1.6 already.
I have started to port Android on TCC89XX board, I download Android SDK. and applied the patch with kernel 2.6.29, the Processor is having armv6 instruction set. I am not able to see the network up ifconfig is not able to show the network devices.
Also I do not get why there is no "on" binary in the system/bin, system/xbin, the init.rc and init.goldfish.rc. I cannot get the zygote process up. create_socket throws error. If any one knows about this, please tell what I need to do correctly or point me to some correct URL's.

I've been doing alot with the initialization routines in android just lately .
For all my efforts I have been unable to get the device-added init action trigger to fire,
Just to be clear this is set in init.rc and looks like the following,
Code:
on device-added-/dev/compass
start akmd
The above is taken from the init readme file which contains an example init.rc at the bottom
I did some further research and a quick search of the AOSP code. This revealed that the functionality is yet to be implemented. which obviously explains why the trigger wasn't being fired . The device-removed and service-exited triggers are also missing.
Is it possible to write data or create folder in system directory like /system/media/audio/alarms. i.e other than our respective package.
View 2 Replies View RelatedI 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 am using Virtual Box with KUbuntu Linux on x86(Windows XP) system and setting up system for Android Source SDK. I have installed repo through (curl http://android.git.kernel.org/repo >~/bin/repo).

Phone: UK Galaxy S Issue: Recovery boot error message in red writing
Multicsc : can not access to / system/csc/VOD/system/
Background: I have been trying to root my phone from information found in a youtube video. All went well and the little ninja bloke with the sniper rifle was in the app list. Tried installing busybox and was told that the phone was not rooted�..
I think I ran the root application again and at some point I started getting this error message when in recovery. I have since run the one click root method to unroot the phone and the little nija dude is no longer there. Since I rooted the phone it will no longer connect to my wireless network, it finds the network and attempts to obtain an ip address. After a few min it times out and tries again. When I load the phone recovery the error message is still present.
