Android :: Failure On Loading Library ?

Sep 2, 2010

I have a similar problem to this question, but slightly different. I have compiled a .so library to use with JNI. Because it is large (15 MB), I am putting it on the SDCard instead of in the standard application place.

The file is called libSample.so and it's located at /data/library/libSample.so

I load it in a static initialization block:

CODE:.............

Here's the relevant logcat output:

CODE:............

I read the post about can android load dll's from sdcard in native mode which said that the sdcard cannot be used to load libraries, so I moved the .so into /data/data/com.example.hellojni/lib/libSample.so (the private app data storage location). No change:

CODE:.............................

What I don't understand is that clearly the library exists, and the OS is trying to load it ... so what would make it fail?

Following the advice of one of the commentors, I tried attaching via strace to get more detailed error information. The log can be found as a github gist.

The error appears to be on lines 47-51:

CODE:...........................

Here's the readelf of the library:

Android 2.2 Phone - Dynamically Loading External Library At Runtime?

Jul 29, 2013

I am using and android 2.2 phone for testing and getting an error.

07-27 01:24:55.692: W/System.err(14319): java.lang.ClassNotFoundException: com.shoaib.AndroidCCL.MyClass in loader dalvik.system.DexClassLoader@43abbc20

First I wrote the following class:

Code:
package org.shoaib.androidccl;
import android.util.Log;
public class MyClass {
public MyClass() {
Log.d(MyClass.class.getName(), "MyClass: constructor called.");
}
public void doSomething() {
Log.d(MyClass.class.getName(), "MyClass: doSomething() called.");
}
}

And I packaged it in a DEX file that I saved on my device's SD card as `/sdcard/testdex.jar`.

Then I wrote the program below, after having removed `MyClass` from my Eclipse project and cleaned it:

Code:

public class Main extends Activity {
[MENTION=1299008]supp[/MENTION]ressWarnings("unchecked")
[MENTION=439709]override[/MENTION]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

[code]....

Android :: Store Values In SharedPreferences In Library Code / Have It To Projects That Include Library?

Nov 11, 2010

I have an Android library project that makes calls to PreferencesManager.getDefaultSharedPreferences.

I have 2 version of my app, paid/free, and they are not able to access the preferences stored by the library code.

Can someone tell me the right way to store values in SharedPreferences in library code and have the values available to projects that include the library?

Android :: Self-contained Test Library Project Cannot Find Library Classes

Aug 17, 2010

According to this SDK guide, unit-testing a Library project can be achieved by creating a standard application project, reference the Library project and then instrument the application for unit testing. However, when I do this and launch the test application I get the message.No tests found with test runner 'JUnit 3".I'm using Eclipse and the Android ADT plugin, all latest versions.the projects compile just fine. The test project also installs fine to the emulator. But in the console I can see that it looks for <library>.apk, which of course doesn't exist since I'm compiling this as a library into the test project.

Android :: Differences Between Jar Library And Library Project

Jul 15, 2010

As I understand, the three ways of distributing my application are via Jar, Android Library and Android Library Project.Jar - cannot contain resources or XML layouts (so this is out for me)Android Library - I don't really know how this works but the Google API uses it..Android Library Project - includes resources but allows the client free rein on the code as it is distributed as source.If I am to create a closed source application that requires drawables and XML files that I want to distribute to other Android programmers, what should I use? And can someone direct me to a tutorial on creating an Android Library?

Android :: Displaying A Now Loading Image While Applic - Loading

May 4, 2009

I want to display a fancy 'loading' image at my app's startup time.

The problem: my startup code is mostly GUI related, hence needs to run on UI thread.

Is there a way to do both - that is run UI-related code on UI thread while an image is displayed to the user?

Android :: AMF Client Library / RTMP Client Library

Apr 26, 2010

Android AMF client library Aftek has extensive experience in developing enterprise Flex applications. We have used BlazeDS extensively and we believe that it would nice to provide all the benefits provided by AMF for Android applications as well. We have developed an Android AMF client library which would enable Android application developers use the same extensively. The Android AMF client library supports remoting and secured remoting. This will allow all android applications to use the existing backend like .NET, Java, or PHP. The implementation is asynchronous in nature providing success and failure callbacks. This allows application to perform other tasks without blocking the application. We are currently performing some performance benchmarking and plan to release our library very soon. We would also be incorporating the messaging feature as well.

Android RTMP client library:Aftek has extensive experience in developing voip and audio/video and media applications. Media applications has a huge market and there would be quite a few people eager to develop the medial applications on Android. We believe that it would nice to provide all the benefits provided by RTMP for Android applications as well. We are developing an Android RTMP client library which would enable Android application developers use the same extensively. Our Android RTMP client library would support some add-ons that would help developers to deliver robust media solutions.

Android :: Loading Activity Darkens Screen - Loading Screen

Nov 2, 2009

I've looked through the documentation and I can't seem to figure out how to have the screen blured/greyed when I select an activity that may take a while to load.

This seems to be an Android standard (both the Camera app and the Camcorder app do it when first selected), but I don't see any documentation on it. I even tried looking through the source of these apps on git, but couldn't seem to find it.

Android TCP Receive Failure

Aug 24, 2012

I am connecting to a server on my network written in C#. The data sent from the android device is received by the server and a reply is succesfully sent but the android code timesout and never gets the return data.I have tested that the C# server can communicate and reply with a C# client.

I have studied the network traffic using Wireshark when using both the C# server-android client and C# server-C# client and it appears that the android device acknowledges(ACK) the reply data but my code never recieves it.

I have the code running in a thread so running it on Android 4.0 doesn't error out but I have tried running it on Android 2.2 with exactly the same behaviour(or lack of it). Also I have run it on 2 different android devices.

(AndroidManifest.xml)
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

Android :: Getting Failure While Trying To Install Layar401.apk

Nov 15, 2010

I have downloaded the Layar401.apk file from web and trying to install it into my android device [HTC Magic, OS 2.2]. But every time I'm trying to install it its saying -

adb install Layar401.apk
1098 KB/s (1855698 bytes in 1.649s)
pkg: /data/local/tmp/Layar401.apk
Failure [INSTALL_FAILED_MISSING_SHARED_LIBRARY]

From other posts I figured out that there might be a missing shared library of google maps api in manifest.xml file. I tried to view the manifest.xml file and it gave me something like following -

package: name='com.layar' versionCode='27' versionName='4.0.1'
uses-permission:'android.permission.ACCESS_NETWORK_STATE'
uses-permission:'android.permission.INTERNET'
uses-permission:'android.permission.ACCESS_COARSE_LOCATION'

densities: '120' '160' '240'

But here it says library includes google maps api as well. So I'm not sure why I'm not able to install this apk file.

Android : Attaching Database Gives Failure 14

Apr 4, 2009

Does the API restrict you from attaching to another database while you have one open?I tried the SQLite3 command "attach database .../contacts.db as aliasdb" .This works in the adb shell and I'm able to perform joins with tables in this database. When I use the same command via the API using "db.execSQL(attach database/contacts.db as aliasdb)" it gives me failure 14.Is this restricted on purpose or am I making a mistake somewhere?

Android : Socket Creation Failure

Feb 3, 2010

I created a simple client socket from my Activity, but it fails. I am running this activity in emulator and server runs on PC(its a different application without Android stuff).

*clientSock = new Socket("127.0.0.1", 30001);*

logcat shows java.net.SocketException: permission denied <maybe missing INTERNET permission>

If I enable permission for my Activity(android.permission.INTERNET), my Activity constructor itself not called and logcat shows following info. Permission Denial: starting Intent < flg=0x10000000 cmp=com.example.client/.MyClientActivity > from null <pid=-1, uid=-1> requires android.permission.INTERNET.

Any suggestion on how to resolve this issue?

Android :: Detecting Socket Connection Failure

Apr 1, 2010

I am working on an app that uses a Socket to connect to a controller over TCP. The protocol library was written in Java and I am implementing it in android via a Service. where the Connection class is a Thread that handles the communications with the controller. It's where the Socket lives.I'm using the Preferences mechanism to store the IP and Port. If I feed the Socket the correct IP and Port, the Connection Service works beautifully. However, I am trying to simulate a user entering the wrong information and having the connection fail. The ultimate goal is to present a dialog and offer the ability to "reconnect" or "update settings". However, when I enter a wrong Port number, the application simply hangs.I was under the impression that Threads executed concurrently so I've tried moving the call to start the Connection Service to a Thread, but it still hangs the application.

Android :: Failure To Connect Camera Service

Mar 11, 2010

I'm trying to write a basic camera app. The problem that I am facing is that it works fine in emulator but on the phone (Nexus one) it fails.

The point of failure is the very first call, i.e. Camera.open(). It fails on the phone saying "Failed to connect to camera service". Any idea what could be wrong? (BTW, I am calling this from my activity's onCreate funtion itself, could that be an issue?)

For the information, I do have the necessary Camera permissions specified in my manifest xml file.

Android :: Failure Rate On 32GB MicroSD

Jul 27, 2010

Hey folks HumanMachine here with a little query for those of you who were lucky enough to have picked up a 32GB MicroSD for your phones.I had, and lost mine, in the course of two days. Short story incoming. TLDR Below I was using my phone at work and decided to change my Live Wallpaper, I'd downloaded a few of them and was going through them just to see how they looked in motion. I remember specifically looking at the "Starfield" wallpaper. I then selected the "Battery - Couple the ship's energy source with phone's battery" To see what the option did. I backed out to apply the Wallpaper. And the Droid X locks. Weird I thought, maybe she's just lagged.Turned out a lot worse than that. She was just straight up frozen. Stuck on this unusable frozen starfield. I couldn't quite remember how to reboot the phone. or even if it were possible, Couldn't power her down, so I removed her battery, figured that would be enough to get her back to life.I was met with a message, once the phone loaded up. "SD Card blank or has unsupported filesystem" Not the first time I've seen this issue pop up on the android forums. I immediately popped the MicroSD card into my little USB dongle and attempted to access the MicroSD. Shows up in "My Computer" just fine. but when I tried to access it? "Please insert disc" et cetera et cetera.

I try to format. No dice, Computer won't even find the thing. Try my SD formatter, no dice.Stick the 16 GB card back into the phone, and we're sailing again. And here I am staring sadly at the card.I tried for about an hour more to breathe some life into it. I just couldn't get the computer or phone to read the card. Same error messages.TLDR For those of you who wanted to skip the story SD Card died. pathetically, didn't lose much but still. My question, do we have any idea what the failure rates are on these bad boys? I didn't mistreat or even do much with mine before this issue came up. Hopefully I just had a lemon. Unfortunately, the store I got mine at. Verizon store actually, didn't have any, nor do they know when they will get a shipment of them.I'm bummed. go figure. Time to play the waiting game.

Android :: Extremely Long DNS Lookup (and Failure) On Mobile Network

Oct 14, 2009

This happens only when my G1 phone is on T-Mobile network: I found that when I try to go to the browser, and type the address:
http://i0.sinaimg.cn/
The browser tries to load the page, but no progress is shown for more than 2 minutes. (I have full 3G signal; all other addresses work just fine). Eventually when I tried to access this URL in my Java code, I found a similar long delay when I try to open the HttpUrlConnection, and eventually I get this exception:

I/InetAddress( 1940): Unknown host i0.sinaimg.cn, throwing UnknownHostException W/System.err( 1940): java.net.UnknownHostException: Host is unresolved: i0.sinaimg.cn:80 W/System.err( 1940): at java.net.Socket.connect(Socket.java:1002)
Why would DNS take so long? Also, if my program tries to issue the same HTTP request again, the same 2+ minute blocking happened. Is this an Android bug or a T-Mobile infrastructure bug? It seems the Android API should try to time-out faster, especially on the second attempt.

Android :: Orientation Specific Failure In ListView.layoutChildren - Exception ArrayIndexOutofBoundsException

Sep 20, 2010

I am a very green android developer and need some help with a strange program crash. Often the program will run just fine. There is an equal chance it will fail (see stack at the end). I can watch the program run through the getView function and everything seems in order (i.e. all the information is there as expected and passes through convertView seemingly fine). Either it will go through a few times and then program will be A-OK or it will fail as seen below and I have not been able to pick out what causes the crash. Even stranger is that if I hold the phone in landscape mode, it will never fail!! It only fails about 50% of the time in portrait orientation.
