Android :: Loading Native Libraries - System Load - Dlopen - Nexus One After FRG83 System Update
Nov 17, 2010I 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.
Android :: Libraries STILL Not Working
Sep 10, 2010I was really excited today when I saw the Tools r7 and ADT 0.9.8 were available and the latter had this note;
Fixes problems with handling of library project names that contain characters that are incompatible with the Eclipse path variable. Now properly sets up the link between the main project and the library project.
I create the library (foolib - no spaces, no caps, no punctuation). So far so good. I go to the main project, go to preferences --> Android. In the library box I add the new library. It appears. I press Apply. I press OK.
Nothing happens.
I return to the preferences, the library is no longer there JUST LIKE BEFORE.
Android :: Working With Apis/Libraries
Oct 2, 2009I'm building an app where I want to architect the app layer separately from the service layer (not android services). So I'll create a service interface(the apis) and then create a class(es) that implement that service interface. Inside the android application layer, I want to code to just that service interface. I think this is similar to how the google maps apis works. the api interface and stubs are in the framework, then each device actually provides the implementation. I don't need to go that far, but I am wondering how I package this up. One, where would I put these interfaces, so I can code to them in the app layer (like Activities). Second, how do I tell Android where the implementing classes are? I'm guessing this is somewhere in the manifest? For now I think I would probably just build the service implementation with the application source code, if that's easier. Eventually I'd like to break that out and drop it in as a 3rd-party jar.

Android :: Are The Maps Libraries Included On Every Phone?
Jul 13, 2010My app uses location services, and has the manifest entry:

Android :: Standard Libraries Not Imported In Phone Project
Mar 7, 2010I'm new to Java/Eclipse/Android, so this is probably an easy (if not stupid) question:
After creating a new Android project, I want to import some (what I think are standard) Java libraries. However, some import statements throw an error:
HelloAndroid.java:
import java.awt.Color; (The import java.awt.Color cannot be resolved)
import javax.imageio.ImageIO; (The import javax.imageio cannot be resolved)
while others don't:
import java.io.File; (no error)
I've done some googling and tried to add these classes to my class path by going to project->properties->libraries but I haven't been able to figure out what to do exactly.

Sprint HTC Hero :: MMS / SMS Stopped Working After Out Of Space Error?
Oct 26, 2009I recieved an error two days ago saying "out of disk space". After restoring my phone to factory the ability to receive MMS/SMS went kaput! Surprisingly I can send but not receive messages. I was on the phone with Sprint for hours with to technicians. One of the techs implied that some of the early batch of phones from Best Buy have this issue. This is just one of the techs viewpoint. I am going to swap the phone today and see if it resolves the issue. I switched to Sprint specifically for TEXT so this could be a deal breaker. More to follow.

Samsung Captivate :: Lag Fix Not Working - Error Message - Stop The Process
Aug 21, 2010Okay -- so I finally mustered up the courage to root and try a lag fix. I rooted using the unleash the beast files. And then tried the lag fix over at XDA found here: xda-developers - View Single Post - [UTIL] One Click Lag Fix 2.0
I ran the lagfix_ext2, like the forum says -- it took about 10 minutes to do some things ...There was an error message in the middle saying that it had to stop the process. I said okay, but the process kept working, finished, and then rebooted. It booted up, and I downloaded quadrant again (it was gone for some reason), ran it, and only ran an 895 -- this is 16 points less than what i ran just using the unleash the beast. Should I try the lag fix again?

Jul 13, 2010I looked around for info on this in the group but couldn't find any... so far in my OpenGL programming I've just done everything directly, but I was curious if anyone had written any "wrapper" libraries for it besides min3d. Min3d is great (or is getting there) but it's GPL'd, making it unsuitable for a commercial product (if my understanding of the license is correct).
View 5 Replies View RelatedAndroid :: Using Gdbserver And JNI Libraries
Oct 15, 2009We have been using gdbserver to debug our JNI code as follows. We have been less than successful -- breakpoints do not always get activated, sometimes we get SIGILL, and we seldom ever get a useful stack when the debugging stops on SIGSEGV, sometimes the program dies with SIGTRAP!!!
We have occasionally been able to have debug sessions with s/n, but since pretty much every SEGV has resulted in either a damaged stack, or at least, gdbserver can not find the stack, it's a pain.
Is there something we are missing? Is there some reason to use the 4.2.1 vs 4.3.1 toolchain? (Why are there two toolchains? I assume because of bugs in each that are fixed in the other... which bugs?)
We guessed that the "dalvik" process that we wanted to debug was app_process --- we found this out by looking at /proc/XXX/cmdline on our running activity.
This is what we do typically do(repo sync directory is in /build/m1 for me)
invoke:/build/m1/prebuilt/linux-x86/toolchain/arm-eabi-4.2.1/bin/arm-eabi- gdb
(some of us use -tui, some of us run it under Xemacs, etc.)
We then do:
CODE:..........
We then start our activity, adb shell, discover the PID of the activity, discover the IP of the phone with "netcfg", and:
app_15 1815 49 107468 15744 ffffffff afe0d4a4 S org.credil.thomas_watson.videophoneservice

This is with a physical device. With an emulator, one has to, of course, run the adb forward stuff. (Too bad that doesn't work with a real device too, as then I would not need to run gdb over the wireless)
