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 : Can I Use Current SharedPreferences Tag To Store Values From PreferenceActivity?

Aug 5, 2010

Currently, I'm using the following code across all of my activities in my app to store application level variables and carry values between activities..

prefs = this.getSharedPreferences("MyPrefs", Context.MODE_PRIVATE);

I didn't have a PreferenceActivity prior to this, but now I do and I am looking to store a few user prefs from this new PreferenceActivity in the same sharedPreferences tag, "MyPrefs".

I know I can access the PreferenceActivity SharedPrefs from my activities via

prefs = PreferenceManager.getDefaultSharedPreferences(this);

but I would like those values saved to my current sharedPreferences tag, "MyPrefs", but I'm not sure how to do this.

Android :: Building Phone Library Projects From Command Line

Jul 29, 2010

I'm updating my application to take advantage of Android library projects. While I can get everything to build fine within Eclipse, I'm stuck trying to update my build.sh script to support library projects. At the moment, I can't figure out what options to pass to appt to tell it to look at my library projects when building my main project. Checking aapt--help has not been illuminating so far. Any suggestions?

Android :: Include Library Based On API Level Or If Statement?

Aug 17, 2010

So I have a API issue. So i am creating a class that utilizes AndroidHttpClient to download Bitmap images from my server. Problem is, it's API Level is 8 and I want this to be used FROM API 1 and above, now i know i can use DefaultHttpClient (the API is Level 1) but is there a way i can use both, being distinguished by Build.VERSION.SDK (btw thanx for the quick respose, Konstantin Burov and iandisme). So for example, if my device is 2.2 i use AndroidHttpClient, anything else use DefaultHttpClient. Of Course if I import the library it will give me an error on any device 1.5 to 2.1. Any Suggestions would greatly be appreciated, because in the future I would want to set other preferences based on API.

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 :: Stack Trace Gives Hex Values Not Function Names When Core Library Crashes

Feb 12, 2009

Here my application "com.android.hello" calls a core library "libvt.so" through JNI call. There is a segmentation fault in "libvt.so". When executed I get the following log What I see is some Hex value followed by a library name. #00 pc afe0d24c /system/lib/libc.so

Also there is a Stack section 01-01 00:02:57.800: INFO/DEBUG(1600): stack: 01-01 00:02:57.800: INFO/DEBUG(1600):bef2e570 bef2e604 [stack] 01-01 00:02:57.810: INFO/DEBUG(1600):bef2e574 afe0a333 /system/ lib/libc.so

This too gives similar information. I am looking for little more informations rather than Hex values. Like the backtrace feature where the stack hex values is mapped to the function names and function names are visible.

Please provide information how to see the function names in stack rather than Hex values. Is ther any compiler options needs to be updated? Any makefile to be updated to enable backtrace?

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 :: Android Library Projects Custom Builds

Aug 9, 2010

I have a legacy application and need to split it into a library project (common code) and two application projects (paid and free applications). I don't use Eclipse for development, and also don't use Ant builds provided (generated) by Android SDK (there are several reasons for that: different project directory structure, unit tests integrated into the build, integration with CruiseControl, automatic builds numbering etc), but use our custom build files instead.

I need to modify my Ant builds to make them build my applications projects that refer my library project. I looked into sample application and Ant builds shipped with SDK, but didn't understand how it is done. I saw that library project contains "libs" directory and "default.properties" file with "android.library" property set to "true". I saw that applications project contains "default.properties" file with "android.library.reference.X" property set to library project directory value. But I didn't find any reference to these properties in the Ant builds (project Ant build file, and Ant builds shipped with SDK). Just placing these files into application/library project directories doesn't help, i.e. SDK tools doesn't interpret them.

My guess is that this is performed by com.android.ant.SetupTask, but I'd like to know how it is performed. My build is set of targets that call (using exec) Android SDK tools: appt, dx, apkbuilder and so on. So I'd like to know which command line parameters I need to use to make, lets say, appt tool to merge resources?

Android :: Package My Common Code As Library

Aug 31, 2009

I have done some cusomtizations on general user interface behavior. I would put those features into my applications. Therefore, I package my source code as a jar and add this external library to my applications.

As my cusomtization include some inflation of xml files, I put those resource in my package. However, when I finished compiled my application and ran it, it reports error. It seems cannot locate the xml file in the jar. (My debugger stop while inflate the xml file). Do I miss any step to use my jar file?

Android :: Using Java Code And JNI Library For Compatibility Purpose?

Aug 7, 2010

I'm writing a JNI library for a game. I have java code that I want to replace with functions from the library. Is it true that most of the devices out there are compatible with my code if I compile it for the default arm processor, or will I find that there are many devices out there that my library won't run on? What I'm asking is, should I maintain java code that does the same thing as my jni library for compatibility purposes, or is it safe to have jni libraries alone? How large is the group of devices that cannot use the libraries I write? Where are there stats regarding what population is using processors other than the arm processors?

Android :: Code Library For Detecting Force-close And Sending Logs

Feb 25, 2010

How many times have you asked users to send you the logcat result to track down a nasty force-close?How many users have actually replied?It's not that users are lazy or busy.Having to run the "logcat" command or download an external log collector app just means too much trouble for them.It should be much simpler. It should be just one tap.In fact I'm surprised (or being ignorant) that an easier error reporting mechanism has not existed yet in the Android API, especially for the infamous force-close. That is why I coded and open-sourced "Android, send me logs!", a small code library that makes it easy to detect force-close and send logs from within your own apps.You can program it to report errors with just one tap, and also include your own tracing information.

Android :: How Can A Code In Library Project Call Code In App Project?

Oct 8, 2010

In an effort to reduce duplication, I have my app's workspace split into 3 projects:
Main (A library project, where all of the common code lives)
Free (To make the free version)
Paid (To make the paid version)
Behavior in the free version and the paid version must differ sometimes. How can I "call into" the final projects from the library project? Here is some sample psuedo-code to illustrate my question: Code...

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.

From what I can incur out of the SharedPreferences documentation, I can update a preference, add one or clear all preference values in a shared preference file.

But I want to completely clear everything inside a shared preference file, not just the values, but the preferences they refer to as well.

Android :: Way To Include Other Java Source Projects In Droid Project?

Sep 18, 2009

Is it possible to include other Java source projects in Eclipse into an Android project? Normally for a regular Java project you do this by adding the other project to the build path and including it in the Project References. This same approach lets the code compile, but when the app is deployed to the emulator, it throws a VerifyError when I try and instantiate classes from my other project. Is this possible with the Android SDK? Do you have to build them to jars and include them inside your Android project like this? I know this works, but just involves more steps to do this.

Android :: String Resource ID Values Guaranteed To Be Consistent Over Different Projects

Jun 7, 2010

I have some messages being passed back from my server through php. The problem is that the messages are in English and if the user is using another language they will still get the message in English.

So I had an idea that maybe instead of passing back the message I would instead pass the String resource Id from the android app, that way the app will get the correct string id for their language. I will use this in a number of apps so I just want to know if the string id is guaranteed to be the same across different android projects?

Android :: Changing Values Inside Layout Included With Include

Oct 28, 2010

I have in many of my screens that re mostly constructed of LinearLayouts a FrameLayout that should take up the bottom leftovers of the screen (using layout_height="0dp" layout_weight="1") inside it there's a FrameLayout with gradients background and in it's middle with some padding lies a button with some text, naturally i need the text and onClicked properties to me different from screen to screen. I considered using <include > tag for the above compound in my layouts, but as far as i can see i can't really change (at least not in xml) the button text and callback, is that really so?
