Service Component is used to do some task which can be done without user interaction. But for that we have to run a thread in subclass of the Service. I think we can create a thread in Activity class itself then what is the use of Service component? Why don't we create another thread and write the non interacting code in this thread.

View 4 Replies View RelatedI have almost completed my Android application so am considering ways of distributing the application. I have seen some applications on Market have free limited/locked version and separate Unlock Key/License Key which unlocks extra functionality. How is this done? Has anyone here done this? If so, how well does it work? I am thinking maybe this is better then having two versions of the same application (i.e Lite and Pro).

If you need to create UI when user need to choose some element of a list, using this non standard component will be more intresting for user. And it is usefull - user can scroll and find a needed value very quickly.
A component I have created works fine if I put it in the main project and reference it from any res/layout xml, but when I put it in a project on which the main project depends, I get a ClassNotFoundException in the xml.
Whilst after compiling the interface works fine, it is a pain in the * to design an interface without seeing what I am doing because of the error. Does anyone know how to solve it?

I have created a simple class named Panel which extends the SurfaceView class and does some drawing in the onDraw method. When I use it from the code it works fine. For example this works as expected:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new Panel(this)); ....
However when I try adding this component from an xml layout the program crashes:
XML file (main.xml):
<?xml version="1.0" encoding="utf-8"?> <org.anddev.Panel android:id="@+id/panel" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"/>
Code:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);....
Error msg: Sorry!
The application Test (process org.anddev) has stopped unexpectedly. Pleas try again.
I can not figure out why the same class works when created in one way and doesn't work when created in another.
I am trying to integrate VP8 video codec into PV opencore FW in Froyo & test at PV test application level. I have done the following steps, 1. Made a new folder for vp8 @ external/opencore/codecs_v2/omx/ omx_vp8. 2. Made appropriate modifications in the omx_baseclass, omx_common etc. 3. Modified the PV test app (external/opencore/codecs_v2/omx/ omx_testapp) for testing VP8. 4. included the VP8 source code to froyo. 5. Included new oscluuid for VP8 With these modifications, the build is fine. The shared libraries and binaries are creating properly. Also OMX-MasterInit is passing. But the application fails at OMX_GetHandle(). *pHandle is coming as zero. I am using the PV OMX core. I am just adding a new codec which is not supported by PV Opencore and test at PV test_app level.Can you please answer my below queries: 1. Do we need to change the pvplayer.cfg file? Bcoz i am using the PC omx_core itself. 2. Any other changes needs to be done for integrating a new component into Opencore? Please provide you valuable inputs. Let me know if need any additional informations.
View 4 Replies View RelatedMy company is in the process of evaluating if we can add support for Android to our product. I am currently working on porting our existing J2ME library to the Android framework and I have a question regarding our UI component. Right now, we have a custom menu that we allow our developers to bring up on the device. On J2ME, we simply have a single call that the developer makes to enter into the menu and then we handle the rest. On Android, it seems the best way to handle this is an Activity. But I have a few questions regarding this approach including is the really the best way to do something like this? Second, if it is, if there are multiple applications on the device that are using our library, are there going to be conflicts with them all having the same Activity embedded in them? Is it possible to create an Actvity at runtime and use it directly? Would there be any side effects of going about it this way?
View 2 Replies View RelatedI am working on couple android applications which share a common component. The component has Activities, Service and own AndroidManifest.xml. After research, it seems there is no concept of run time share library among applications in Android. So I am looking for a way to linked the share component with other applications at compile time. Applications which will use the component can come from external, therefore I will only provided the compiled file. I would like to build the component into own apk or jar file, can external application include my jar/apk file into their package and be able to start my activity? Please share your experience and advice.

View 2 Replies View RelatedIN our current project, I need to make a UI describled as follows.
Basically it is a text input, it will display a string returned from server , such as "I like banana". The word "banana" will be in red color. When user clicks "banana", it will have a dropdown list shows "apple, orange, pear". User would be able to select one of them, like apple. So the text in that UI would be "I like apple".
How could I build such a UI component in Android.

View 3 Replies View RelatedI am doing authentication with a third-party site that's supposed to redirect back to my app with auth token (OAUTH).
I have the callback working properly if I open the 3rd party site in a separate browser process via this.startActivity(new Intent(Intent.ACTION_VIEW, uri));
But, if I embed a WebView component in my layout, and open the url in that, the callback does not work. Webview says "You do not have permission to open myapp://callback?token=...." and quickly refreshes to "Web page not available...temporarily down..."

First of all let me say that i am new to the JNI. However, i gathered some knowledge about it. As i was going through the android_media_MediaPlayer.cpp in ase mediajni to understand the way of operations of the android media framework, i saw the signatures of the JNI functions don't contain JNIEXPORT and JNICALL macros. Have these macros become redundant in JNI 1.4?
View 2 Replies View RelatedI am a game developer and have developed a nice global high scores module. The source code is in two different games of mine and anytime I make changes I carefully copy and paste the java files from one project to the other. As I increase the sophistication of this module, the copying and pasting can take a day or two to make sure I get it right. Now I am finishing up my third game and want to add the high scores module, but copying and pasting this in three separate projects seems absurd and will take up much of my time! Is there any way to externalize this module?
Unfortunately, the module makes reference to R for strings, layouts and other resources. It also uses common Android functions and resources from the Android library. Almost anything would be easier than the method I am using now--so any and all suggestions are welcome!

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));}
I've made a little test component that overrides ImageView, called myImageView, and prints some text and an arrayList of Doubles over whatever image is specified in the related xml. However, right now, the text and Doubles that are drawn over the image are defined within the myImageView class. Is there a way to pass the data from the main onCreate function to the myImageView class before the layout is drawn?
I'm new to OO programming, but based on my understanding of this:
http://developer.android.com/guide/topics/ui/custom-components.html
It's possible because ImageView is just like any other class. This leaves me with two initial guesses:
1. I could generate my test data in the main onCreate, and store it in the array's xml file, and then read that xml file with myImageView,
OR
2. I could extend view instead of ImageView, but because of my new- ness, then I would lose the ability to use it in an xml layout sense - and that's what I really want.
Could developer upload 'component'/SDK to android market? Now it seems only have 2 type: 'application' and 'Game'. I just wonder if android market has the mechanism for developers to upload component-wise programs which can be used in others's application. Then developers may get benefit from earch others. Or Is android provide a easy way to invok and communicate with other application from one application?
View 4 Replies View RelatedWondering if we have few buttons on a LinearLayout, is it possible to set focus to a button programmatically?
View 4 Replies View RelatedI'll preface this with, I've just started learning Android so be gentle.
I come from an ASP.NET / Silverlight background so I was looking for something along the lines of controls.
I want to reuse a layout (a ListView item template) in other layouts.
Such that in my other layouts I can just add <myListItem /> to show it.
Is this, or anything like it possible? or are there better ways?
I'm just starting out on Android and Java programming, coming in from a C++ background. I was wondering - whats the best way to go about making a library/UI widget/component that I can license to third-party developers?
In C++ I'd ship the customers my headers and *.a files, but I don't know the equivalent in Java. Are there any good resources or links about this, maybe even from general Java development standpoint.
my application caches static resources in its /assets directory and implements a content provider to provide them to a WebView on request. i kinda have to drive around the houses a bit because it seems i can't get a linear file descriptor on an asset, i get "this resource is zipped" or somesuch, don't know why that's a problem. the content provider just caches the asset in /sdcard and then returns a file descriptor off that. this has been mostly working fine, but i've started seeing errors from the PackageManager. nothing's changed on my end, the assets are still there, etc. the actual error i'm getting is -ndroid.content.pm.PackageManager$NameNotFoundException: ComponentInfo{package/activity} (where "package" is the name of the package, etc) can i get anything wrong with this stuff? caching javascript and css stuff in the apk has been a big performance win.
View 6 Replies View RelatedI've prepared custom component based on LinearLayout. Whole component is defined in XML. Currently to use it you have to write:
<com.xxx.android.components.TopMenu
android:layout_width="fill_parent"
android:layout_height="44dp" />
Is it possible to set width and height in the java constructor? So it would be possible to write just:
<com.xxx.android.components.TopMenu />
I've tried to modify and set LayoutParams, but it didn't work for me.
I've created custom compound component and observe very strange exception (google says nothing about it). Custom component rare exception: Parser is not a BridgeXmlBlockParser!
It is very simple:
public class MyTabber extends LinearLayout {
.. public MyTabber(Context context) { super(context);
Init(context); }
I have made a Custom Component in XML, consisting of a button with an imageview stacked on top of it:
<myapp.widget.ClearableCaptionedButton
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:id="@+id/ccbutton_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical|left"
android:textAppearance="?android:attr/textAppearanceMedium"
android:background="@android:drawable/edit_text"/>
<ImageView
android:id="@+id/ccbutton_clear"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="5dip"
android:layout_alignRight="@id/ccbutton_button"
android:layout_alignTop="@id/ccbutton_button"
android:layout_alignBottom="@id/ccbutton_button"/>
</myapp.widget.ClearableCaptionedButton>
Extract of java source code:
public class ClearableCaptionedButton extends RelativeLayout implements OnClickListener {
...
public ClearableCaptionedButton(Context context, AttributeSet attrs) { super(context, attrs);
// some stuff that works fine
} ..
protected void onFinishInflate() { super.onFinishInflate();
mButton = (Button) findViewById(R.id.ccbutton_button);
mClear = (ImageView) findViewById(R.id.ccbutton_clear);
mButton.setText(""); // error here: mButton == null
}
My problem is similar to this one. When I try to find the views inside the custom compound, findViewById returns null. But, as you can see, i already added super(context, attrs); to the constructor. I am using the custom component directly in xml layout, like this:
<LinearLayout>
<!-- some stuff -->
<myapp.widget.ClearableCaptionedButton
android:layout_width="fill_parent"
android:layout_height="wrap_content"
app:caption="to"/>
</LinearLayout>
I got a null pointer exception in an Activity onCreate() while trying to access my Application object (extended from android.app.Application).This exception occurred very rarely and i have no way to reproduce this again.My App starts a service on BOOT_COMPLETED intent and the null pointer exception seems to have occurred during boot up. Can somebody please throw some light on this issue? Application should have been created before creating any activities.
