LOCAL_SHARED_LIBRARIES and LOCAL_LDLIBS

Question:

hello
i would like to ask the differences between
LOCAL_SHARED_LIBRARIES and LOCAL_LDLIBS
for example , i try to link skia
in mydroid
 i need to use LOCAL_SHARED_LIBRARIES = libskia
but in NDK
i need to use LOCAL_LDLIBS = -lskia
so i am wondering what's the differences
and why do i need to two different ways for my Android.mk

thanks 

Solution:


Libraries that are linked via LOCAL_LDLIBS will not have any
dependencies generated for them. So, typically, LOCAL_LDLIBS should be
used when you don't want to or don't have the resources to build the
specific library. So, if you are using a library provided by the NDK,
you *technically* don't need to rebuild the provided libraries.

So, in your case, in your "mydrdoid", if you use:
LOCAL_LDLIBS := -lskia" ...then, libskia.so *need not* be rebuilt.
whereas, if you use:
LOCAL_SHARED_LIBRARIES := libskia ... then libskia.so *will* be
rebuilt if there are any changes in it's dependencies.

How to draw an overlay on a SurfaceView used by Camera on Android?

Solution 1: I have a simple program that draws the preview of the Camera into a SurfaceView . What I'm trying to do is using the onPreviewFrame method, which is invoked each time a new frame is drawn into the SurfaceView , in order to execute the invalidate method which is supposed to invoke the onDraw method. In fact, the onDraw method is being invoked, but nothing there is being printed (I guess the camera preview is overwriting the text I'm trying to draw). This is a simplify version of the SurfaceView subclass I have: public class Superficie extends SurfaceView implements SurfaceHolder . Callback { SurfaceHolder mHolder ; public Camera camera ; Superficie ( Context context ) { super ( context ); mHolder = getHolder (); mHolder . addCallback ( this ); mHolder . setType ( SurfaceHolder . SURFACE_TYPE_PUSH_BUFFERS ); } public void surfaceCreated ( final SurfaceHolder holder ) { camera = Camera . open (); try {

Create EditText with dropdown in android

EditText is a view which is used so frequently in Android application,specially in applications which has forms which allow user to fill information of any kind. When you have filled any form you must have a faced an problem (specially on mobile devices) ie. deleting the text written in EditText and prepare editable dropdown which allows to enter manual data with dropdown. So I have created my own custom EditText ie. DropDownEditText.This customized view contains a Button inside the EditText itself. So just on pressing this Button only once you can populate the dropdown with ArrayAdapter. So here my code goes… First XML code for customized view. dropdown_edit_text.xml <?xml version=”1.0″ encoding=”utf-8″?> <RelativeLayout xmlns:android=”http://schemas.android.com/apk/res/android"; android:layout_width=”fill_parent” android:layout_height=”wrap_content” > <EditText android:id=”@+id/dropdown_edit” android:layout_width=”fill_parent” androi
