Android : Create A Custom Library To Use Across Several Appilcations?
Dec 1, 2009
Is it possible to create a custom library in android (having its own layout resources) for use across several android applications?
I created a regular *.jar file but when I tried to create/style my views dynamically most of the properties do not work. Even referencing simple styles from the android.jar file such as android.attr.listSeparatorTextViewStyle did not work.
I created an android project without any Activity, having its own resource files and then referenced this project from another Android project to use in its build path. Everything seems to work fine but the emulator keeps crashing (with no meaningful error message in the LogCat) when I try to run the project.

I'm trying to create an app for Android that simply sends a command to an SSH server. No response needed, I just need to be able to send a command. I was wondering if there's any java library out there that I could use? No advanced stuff needed, just a pure connection to send the command.

I'm new to JNI, i'm developing a native library for an Android project. I read some papers about JNI programming but i didn't understand if it is possible to create a library that can be loaded in different project classes with different packages. I read that to declare a new JNI method the syntax is:
the prefix "Java_"
an encoded fully qualified class name
an underscore ("_") separator
an encoded method name
Based on this definition it shouldn't be possible...
Suppose i had defined a class A in the package pkg1 with the native method foo contained in libfoo, and then i defined a class B in the package pkg2. Can i use libfoo and the foo method in B? How should i define the native method to achieve the result?

I have several apps (each in its own apk, process etc) running at the same time on user's device.
these apps are all linked to a single common jar file (internally devloped) which contains a large portion of their overall code size.
is there a way for me to force Android to make this common jar load only once (e.g. into shared memory)?
the reason we want to do it this way, btw, are to reduction of each of the single apps memory intake, on disk footprint and possibly of their startup time.

How i can create android project's library that can be used in any different project. I create a jar file that contains all activities and add this jar file into my eclipse project build path. But if i need to use any activity then i must need to register this jar activity into my project AndroidManifest.xml. This looks very odd. I need a solution in which i have a jar or any other deployable file that contains multiple activities and any user can use them in his project without registering these jar activities into NEW android application AndroidManifest.xml file.

I am a Delphi programmer and have written, over the years, hundreds of classes and routines which I can use in every Delphi program I write. This library is called d lib and can be *used in every Delphi program by putting this folder in my library path and using one of the units in the uses section of a Delphi unit. Being completely new to Java and Android development, I am wondering how to do this in s similar way. So my question, how can I write own classes, put them in some global folder, and use these classes and routines in every Android program I write ? I know this is a basic question, which I can probably find out by searching Google and trying it out in Eclipse, but if someone can put me on the right track, I know I will save much time.

Sometimes when I try to install custom roms with odin3 I get a Microsoft Visual C++ Runtime Library error. It always says: "This application has requested the Runtime to terminate in an unusual way. Please contact the application's support team for more information". Right now, I am trying to flash a custom rom and it is giving me this. Do I need to change something in the data.img or something?

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?

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?

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.

PreferenceManager contains very useful methods like "registerOnActivityResultListener" which enables you to call startActivityForResult in your custom preference like RingtonePreference does but it's restricted at the package level.So tell me, let's say I wanted a ImagePreference. How should I proceed? I want to be able to use a activity for result intent with the PICK action.

I'm trying to create a component using an xml layout file. I defined a layout with some custom attributes. This layout is inflated when user add it inside another layout. My problem is I don't know the parent, so I pass null for the parent viewgroup when I call inflate method. I think that's the reason why I see anything in my view. Do you know how can I do (I don't want to redefine onDraw method because I use existing component). Below my xml layout and my custom class.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content">
<ImageView android:id="@+id/img_btn_option" android:layout_width="wrap_content" android:layout_height="wrap_content"/>
<TextView android:id="@+id/txt_btn_option" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_toRightOf="@id/img_btn_option"
android:textColor="@color/font_white" android:textStyle="bold"/>
</RelativeLayout> public class ButtonOptionsView extends View {
public ButtonOptionsView(Context context, AttributeSet attrs) {
super(context, attrs);
LayoutInflater li =(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout vg =(RelativeLayout)li.inflate(R.layout.button_option, null);
TypedArray ta = getContext().obtainStyledAttributes(attrs,R.styleable.ButtonOption);
((ImageView)vg.findViewById(R.id.img_btn_option)).setImageResource(ta.getResourceId(R.styleable.ButtonOption_image,0));
((TextView)vg.findViewById(R.id.txt_btn_option)).setText(ta.getResourceId(R.styleable.ButtonOption_text,0));}

How can I create Spinner with customized items?

I tried to create custom ArrayAdapter for the Spinner but I just can't figure out how to do it.
