Android :: System.setProperty - Cannot Change System Property In Android

Sep 23, 2009

I use Java API "System.setProperty()" to set a system property. After invoke "System.setProperty()", API "System.getProperty()" can return the value just I set. However, when I use command "adb shell getprop" to verify, it shows that this property is not set at all. Do I wrongly understand API "System.setProperty()" ?

Android :: Loading Native Libraries - System Load - Dlopen - Nexus One After FRG83 System Update

Nov 17, 2010

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.

Samsung Galaxy S : Recovery Boot Error - Can Not Access To /system/csc/VOD/system

Sep 4, 2010

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.

HTC Eris :: Change Android System Fonts - Root Req

Aug 9, 2010

How to change the fonts on your rooted Droid Eris. I'm not sure if this works for all Android phones, so backup your phone before proceeding. This DOES change key Android files, so be careful. If you brick your phone, it's not my fault.

First of all, go to this website and find a font you like:

1001 Free Fonts - Download Free Fonts for Windows and Macintosh

The file you download should be a .zip, and when unzipped be in the format .TTF. Copy the .TTF file to your SD card. I suggest SDCard/Fonts/. After finding a nice font, download Type Fresh from the Market (free). Also, pick up AndExplorer (free) while you're there. Type Fresh will allow you to change your fonts, and Andexplorer is used as a handy file explorer.

Run Type Fresh, and it will display all the system fonts that Android uses. Touch DroidSans, and it will display a window using AndExplorer. At this point it should request superuser permissions; allow it. Find the folder with your fonts, select a font, and press okay. Press menu and select apply fonts. Allow it to reboot your phone when it asks, and afterwards you should have a nice new font to make your Eris even sexier.

Android :: Change System Settings From Droid Widget?

Apr 12, 2010

I have a widget that changes some system settings, but it will not take right away. It seems like I need to refresh the system settings for it to take. How do you change some system settings from a widget that take instantly?

when my widget is pressed it goes to an activity with a blank background to change the system settings. one of the settings that are changed is the display brightness. this is the code i use to change the display brightness. once i change the settings i call the finish function to exit the activity so i am not stuck there after the settings are changed. One thing i did notice is that if i didnt exit the activity the settings did change, but i was stuck in the activity. its when i added the class.this.finish(); to exit the activity that the settings don't change. code...

Android :: Android System - System Context - Replace Classes

Oct 12, 2010

I'm engineer but more from a chip/assembler x86 level. I'm new to Android. Still figuring some general things out. I have written some apps, but have a general question. If I were to write an improved version of - let's say - TextView. Is it possible to make all app's on the system using this class, basically replace TextView? How are the java classes on the Android system, are they compiled, can I replace the library? Is this protected?

Change Content Management System

Nov 20, 2012

I've recently started programming my first android app in eclipse using java and xml and I'm relatively new to both languages.

My App will contain mostly static information for students in university which I plan to simply save as text in the xml itself but the clients wish to have a few pages on the app with content that they will be able to change regularly without having to look at or understand any code.

Basically what I'm looking to do is have a basic content management system that can only be accessed by the client and they can use it easily enough to change the content of those specific pages.

Motorola Droid : How To Change System Font?

Feb 19, 2010

I've been messing around with metamorph, and thank the members here for pointing me in the right direction to find the themes I am currently running the I.C.E. theme by tdawg. Everything applied correctly on top of Sholes 2.0.5, without messing up any performance tweaks. Only thing that did NOT apply(no surprise) is the font in the screenshots. I'd like to have this font- it is the same in the Droidinator theme and a few others I have seen screenshots of. So my question is.. where to I find this font, and how do I apply it(Hopefully through a terminal emulator since that is all I have set up so far)?
