[android-developers] Img tag replaced in Intent

[rochdev]

Hi,

I'm unsure if this is a feature or a bug.

What I'm trying to do is to pass some styled text between two
activities.

final Intent intent = new Intent(this, ActivityB.class);
intent.putExtra("message", Html.fromHtml("My image 
http://example.com/image.png\"; />", imageGetter, null));
startActivity(intent);

Then when I retrieve my text in the new Activity the entire img tag is
replaced by  (OBJ - symbol).

CharSequence message = intent.getCharSequenceExtra("message");

START message
My image 

END

Any thoughts?

[android-developers] Re: authentication of an app in facebook

[Ali Chousein]

@Anusha: Try using the Facebook SDK for Android and follow one of the
examples. It should just work. I've integrated the Facebook SDK in my
own application and didn't face any difficulties. Try running one of
the provided examples by Facebook (if you are using Eclipse you need
to integrate both projects for the example and the Facebook SDK) and
follow the code of this example. Please don't forget to use your own
application ID, otherwise it won't work.

@TreKing: Any Android SDK integration question can perfectly be asked
here. Please don't try to stop the majority of the discussions. You
are neither the police nor the owner of this platform; so please don't
try to act like one. If you don't know the answer just don't write
anything. The question of Anusha was perfectly valid: Integration of
Facebook Android SDK. He is not talking about Hong Kong stock exhange.
Really, please, don't try to stop the majority of the discussions. Do
it like the rest of us. If you don't have anything to say, please
don't react. It's easier. Some of the members are really newbies, but
probably eager to learn and also with talent. Don't forget, you also
used to be a newbie.

Re: [android-developers] Re: Need someone to test app on physical device 2.3, 3.0, 31

[Raghav Sood]

Thanks. The app is non commercial and free. It is also open source. I was
just uploading the source but it is taking a while. As it is not really
dependent on screen configurations like a game I suppose I could follow
TreKing's advice. I haven't integrated a bug reporting system as yet but I
will have it done by the next version.

You might want to say so in the first place. If it's non-commercial,
volunteer project, etc, people might want to help.

Doing this on a real device doesn't really buy you much, you can
do the same thing on the emulator. Thorough testing on a real device
might uncover some more obscure bugs (including in Android), but
just a quick run will only get you 'it works'.

If you tested on two devices and several emulators, really, you should be
fine assuming you're not doing anything crazy in your app. Even if someone
confirmed that your app ran on X.Y device, there is no guarantee that it
won't break doing something specific a user would do in a real world
situation or running on another specific phone.

Testing is good but really the only apps that require such intense testing
across many devices are games and such that depend highly on the screen and
hardware. For example I've never tested my app on 3.0 (no device and don't
want to bother with the emulator) but I know it works fine from talking to a
user.

If you haven't already, incorporated ACRA or some such bug reporting
mechanism into your app then release it to the wild and fix the bugs as they
come - and they will come, I don't care how many quick < 5 minute tests you
manage to get.

Nikolay, I cannot pay the testers. I am 14 years old. It is unlikely that
someone would do it for free but it is worth a shot as opposed to buying the
required devices, which is out of my budget for a very long time. I am not
asking anyone to conduct a test that goes over each and everything of the
app. All I want to know is if it starts, displays a list of earthquakes and
whether or not the preferences (apart from auto update) work. It will take
less than 5 minutes and the apk is less than 50kb.

How much are you willing to pay testers? Don't expect people to
do it for free. If you are in contact with some of users, you can ask
them to test your app (in exchange for a free upgrade or something).

There are also places that you can go and test on different devices
(for a fee). Some sites offer to do it for you, don't know how much
you can trust those.

[android-developers] In which way should I read a video file in binary mode into a byte buffer?

[Jiabin Qin]

I searched Google and found several ways , but I am not sure which is
the correct one.

File mFilePtr = new File(getExternalFilesDir(null), mFilename);
InputStream is = getResources().openRawResource(id);
is.read(mBuffer, 0, bufsize);

The doubt for this is , in the method: openRawResource(id), on the
developers site, it says:
Open a data stream for reading a raw resource. This can only be used
with resources whose value is the name of an asset files -- that is,
it can be used to open drawable, sound, and raw resources; it will
fail on string and color resources.
id The resource identifier to open, as generated by the appt tool.

Is it ok to read my video in that way?

Thanks in advance!

[android-developers] Need someone to test app on physical device 2.3, 3.0, 31

[Raghav Sood]

Hi all,

I recently finished the first version of one of my apps. I wrote it for
android 2.2, but later re wrote parts of it so that it would work on 2.1 as
well. I have tested it on the 2.1, 2.2 and 2.3 emulators and 2.1 and 2.2
devices. I would appreciate it if someone could test it on a physical device
running 2.3, 3.0 or 3.1 and post back the results. There are some problems
like the autoupdate does not work as of now which I am aware of. The app is
not malware. It is meant to display a list of earthquakes in the past 24
hours in the United States. I am working on adding more countries.

Thanks

[android-developers] Re: Keyboard Show/Hide Notification

[Spiral123]

Hi Prasanna...

That still doesn't answer the question.  Why do you want to notify the
app that the keyboard has been shown/hidden?  What do you want the app
to do with that information?

If you can tell us the answer to these questions then I believe
someone will be able to help you accomplish what you want.

result from the UI thread to minimize the memory footprint.

For anyone interested this is the fixed code:

public FrameLayoutWithOfflineBitmap(Context context) {
super(context);
paint = new Paint();
paint.setColor(Color.BLACK);

[android-developers] What is the difference between the garbage collector calls GC Explicit, GC For Malloc, and GC External Malloc?

[Greg Siano]

I want to know how many times my game is causing the garbage collector
to run but I don't know which calls I should be looking for, and maybe
some of them are not from my application and are unavoidable.

[android-developers] best way to implement a thread requring a result from a function that must be run on the UI thread

[rukiman]

I am in a thread that I did not create, its part of a library and I
need to generate a result which can only be done in the UI thread.
Any good tutorial on the best way to achieve this?

I know I will have to post a handler to the UI thread, but whats the
best way for the UI thread to return the result? And I have to make
the other thread wait for the result.

A good code snipped would help. Thanks.

Just to confirm the OP's experience, I've noticed that a lot of other apps

their root view... but the problem isn't limited to webview.

The Sensation has an odd resolution.

[android-developers] Re: How to Implement Drag And Drop for image views by extending View Group

[davemac]

Are you doing this in Android 3 or an earlier version? There's direct
support for drag and drop since Android 3.0 so it's much easier. See
the DragEvent class. But it's possible prior to Android 3.0, just
harder.

[android-developers] Re: weird behaviour while overriding FrameLayout.dispatchDraw() on a view that contains a scrollview

[rukiman]

Found the issue is because I have to clear the bitmap first before
rendering the view onto it, the edges are transparent and its showing
through to what was drawn before.
Question is how would I know what color to clear the bitmap with?

Re: [android-developers] Re: weird behaviour while overriding FrameLayout.dispatchDraw() on a view that contains a scrollview

[Romain Guy]

The drawing cache is per view, so if you need to capture several views
(sibling, and not a subtree like you are doing in your example) if
would be better to allocate a single bitmap. This works of course only
if all the views have the same size.

[android-developers] Re: weird behaviour while overriding FrameLayout.dispatchDraw() on a view that contains a scrollview

Also its not technically double the work load, as I suspect the
children views take much longer to render themselves compared to
simply drawing a bitmap out to the screen.

[android-developers] Re: weird behaviour while overriding FrameLayout.dispatchDraw() on a view that contains a scrollview

[rukiman]

I am suspecting using the view cache system causes the view system to
allocate memory for the view.
Now lets say I can to capture 3 views, does that mean memory is
allocated for 3 views worth of caches if I don't destroy the cache?

Also I noticed through profiling that this code runs around 100ms
view.setDrawingCacheEnabled(true);
view.setDrawingCacheQuality(View.DRAWING_CACHE_QUALITY_HIGH);
view.setDrawingCacheBackgroundColor(Color.BLACK);
Bitmap bitmap = view.getDrawingCache();
Bitmap retVal = bitmap == null ? null :
bitmap.copy(bitmap.getConfig(), false);
view.destroyDrawingCache();
view.setDrawingCacheEnabled(false);
return retVal;

while this runs at around 60ms
mCanvas.setBitmap(mBitmapCapture);
   view.draw(mCanvas);
   Bitmap retVal = mBitmapCapture;

I have to capture a few views and trying to speed them as quick as
possible and at the same time not use much memory. I guess the slight
speed difference is in enabling and destroying the view drawing cache?
What is the effect of not destroying it? Does that mean it will suffer
from my approach above that is double the workload on each frame as
well?

Going back to my approach my code is just as I pasted it, should I be
saving the canvas and restoring it in the dispatchDraw? Any help is
appreciated. Thanks.

Re: [android-developers] weird behaviour while overriding FrameLayout.dispatchDraw() on a view that contains a scrollview

[Romain Guy]

It's either because you don't properly save/restore the state of your
offline Canvas or maybe because of the bitmap config (although it
should work just fine in 565.)

What I don't understand however is why you refuse to use the drawing
cache API that already exists for this purpose? Using this API will
not necessarily force another redraw of the view. With the drawing
cache, the cache is automatically redrawn whenever the view changes.
Your approach however doubles the workload on *every* frame.

[android-developers] weird behaviour while overriding FrameLayout.dispatchDraw() on a view that contains a scrollview

[rukiman]

I am trying to understand which this code which works perfectly for
capturing almost any view except if there is a ScrollView in the
framelayout, in this case there is a slight issue with the top and
bottom areas where scrollview fades its contents. There is some
corruption occurring.

public class FrameLayoutWithOfflineBitmap extends FrameLayout {

private Bitmap mOfflineBitmap;
private Canvas mOfflineCanvas;

public FrameLayoutWithOfflineBitmap(Context context) {
super(context);
}

@Override
public void onSizeChanged(int w, int h, int oldw, int oldh) {
// just in case we already had the bitmap allocated before
if(mOfflineBitmap != null) {
mOfflineBitmap.recycle();
}
mOfflineBitmap = Bitmap.createBitmap(w, h, 
Bitmap.Config.RGB_565);
mOfflineCanvas = new Canvas();
mOfflineCanvas.setBitmap(mOfflineBitmap);
}

@Override
public void dispatchDraw(Canvas canvas) {
// draw to our offline bitmap
super.dispatchDraw(mOfflineCanvas);
// now draw our offline bitmap to the system canvas
canvas.drawBitmap(mOfflineBitmap, 0, 0, null);
}

public Bitmap getScreenSnapshot() {
return mOfflineBitmap;
}
}

I understand there are other ways to capture the view such as using
the View's drawing cache, but I am not interested in this method. Can
someone explain to me what is going on here and if there is way to
address this issue? Basically I am trying to get access to a snapshot
of a view as quick as possible. My idea is that the view is already
drawn onto the screen, we should be able to get access to this without
having to force another redundant redraw of the view.

I am also very keen to understand the flaw with the above code in
terms of the scrollview. Thanks.

OP asked "How can i update my spinner with the last value i have choise,
using shared preference??"

Taking the question at face value, this implies to me A) getting and setting
the value from / to a Spinner, which you can do with obviously named methods
and B) getting and setting this value from / to a SharedPreference, which
you can also do with equally obviously named methods.

The details of a full working scenario are, of course, a bit more involved
but given the question, the answer is readily obtained by a good perusal of
the docs, IMHO.

OK - seems beyond the scope of the question posed though.

An Android Adapter provides the interface by which a user-defined object can
be used and represented in Android's system. It "adapts" your object to
Android's way of displaying data. Seems aptly named to me.

Update it every minute, regardless of whether it is visible. Use
AlarmManager and a non-WAKEUP alarm instead of
android:updatePeriodMillis if you do not want to wake up the phone.
Ideally, you would allow the user to configure the update interval --
while you may think every minute is a fine answer, users may disagree.

I don't have a solution to your problem, but I just got a Sensation and my

Well now, TreKing, I have read the documentation on both, and I still

SpinnerAdapter. Even what seems 'obvious' after reading all that just

Change your build target to one that has Google Maps. In Eclipse, this

[android-developers] Re: ANR in process

[Indicator Veritatis]

It always helps to give an explicit example of a Google query he could
have used to answer his question. I found the answer in the top item
listed after searching google with "android developer anr", which is
titled "Design for responsiveness" and says:

"Generally, the system displays an ANR if an application cannot
respond to user input. ... In both of these cases, the recommended
approach is to create a child thread and do most of your work there."

It is almost certain that that is the right answer for his problem. If
not, then he should still read the rest of the article -- as well as
look for what platform methods he might be using that are running on
the main UI thread when they should not be...

[android-developers] Re: Join us for "Android Programming June 23rd, 2011 Webinar - "Testing""

[Indicator Veritatis]

Please don't niggle, Mr. Niggle;)

Most likely the reason is that the software for connecting you to the
Webinar only runs on Windows or Mac OS, NOT because they really have
anything against developing for Android under Linux (I use Fedora, not
Ubuntu, with few complaints).

[android-developers] Re: Orientation change action

[Oleg V]

I've actually been looking for a solution to this quandary for some time. 
The quickest is just to add this property to each activity tag in your 
AndroidManifest.xml file:

*android*:configChanges="keyboardHidden|*orientation*"


However, this won't keep your task/download working if, say, the user takes 
a call or presses the home key. However, although the official documentation 
advises against using this method, it is actually used in the messaging 
application.

Anyways, you probably want a more robust method. To do this, you can either:

   1. Create a service and work with downloads in there, and communicate 
   with your UI activity if it exists. This approach is better if you have some 
   sort of download manager or feed updater that must work in the background
   2. Work in AsyncTask, which is better for shorter tasks (if you want to 
   quickly fetch a file, parse it, and update the user interface). There are a 
   few techniques here. You can pass references to your task when the activity 
   is destroyed between orientation changes 
   with onRetainNonConfigurationInstance(). Or, you can hold the reference to 
   your task by holding it in the Application object, accessible to all 
   activities. Have a look at 
   
http://www.fattybeagle.com/2011/02/15/android-asynctasks-during-a-screen-rotation-part-ii/
 for 
   code (and read Part I where the author goes over the other possibilities)
   
Hope this helps!

[android-developers] Please help me with this issue

[Jatin Salla]

I am new to Android and have almost completed developing the Mobile
app which consumes the REST service and also uses Google API for this
app.
This application is developed in Android Version 2.3.3 API level 10
(Google API (Google Inc.) - API level 10).

I thought of checking the backward compatibility of the app I created,
hence changed the AVD (also tried creating new AVD) to point to
Android version 2.1.1(Google API (Google Inc.) - API Level 7).

But When I started the Emulator with this new AVD the app is not
running and I check the logcat and getting following issue in the
logcat

[android-developers] when will you start fixing earlier mentioned vpn issues with l2tp for example

[evils0n]

instead of coming with 100 new features that are buggy why cant you
start fixing in problems with ipsec/vpn for example. Lots of people
having issues with this and there is no work around unless you
constantly using the mobilenetwork if you shall connect over vpn by
using l2tp (psk) dream on if you want to do this over wifi and natted
networks. Or you getting money from the mobileoperators for this?
Frankly this is a "bug" that been since 2.1 when i started to use my
htc hero atleast it have never worked as it supposed to do.

My statistics didn't update the last two weeks, too (Using Andlytics,

[android-developers] MASTERION.COM social application network available

[Iván Martínez]

Hello everybody, I hope this is not regarded as spam, as it is the
announcement of a useful development resource.

I'm proud to announce the availability of MASTERION, a messaging
server aimed to serve social applications (such as games). MASTERION
differs from similar networks in the use of the XMPP protocol, making
it available to any application regardless its implementation
language, operating system or hardware. It differs from other XMPP
servers in its plans to implement specific features for social
applications (for example, scoreboards).

There are plenty of libraries that help implementing XMPP clients.
Check http://xmpp.org/ for more info about the protocol. Check
http://masterion.com for more info about MASTERION.

I'm posting this announcement in many places and unfortunately I can't
follow the discussion everywhere. If you have any question, please get
a MASTERION developer account as described in 
http://masterion.com/developers/about-masterion
and post it in http://masterion.com/forum, or write to the Development
Support address in http://masterion.com/contact

Thank you for your attention, I'm looking forward for your feedback.

Ivan Martinez

[android-developers] BlueZ version in Android Honeycomb

[Thomas G.]

Hello,

I'd like to know a way to know the version of BlueZ (the bluetooth
stack) implemented in Android Honeycomb, without having the source
code of Honeycomb. I am pretty interested in the HDP functionalities
offered by the last versions of this stack.
Also, I heard that it is not recommended to use bluetooth
functionalities by another way than through the Java API, is this
true? Can't we use the embedded libbluetooth.so without trouble?

Thanks a lot!

[android-developers] Re: When to close db connection on android?

[Michael Kuethe]

Hi Jay,
no you just have to call the closing mechanism once. Normally during
the onDestroy() event of last Activity that remains on the system.
This is normally the launcher Activity.

@Override
protected void onDestroy() {
Log.d(TAG, "onDestroy fired!");
dbhelper.close();
super.onDestroy();
}


regards

Michael

[android-developers] Re: Problem with getting GPS data when using Camera

[b.rye]

Have you come across a solution to this? I've recently seen this problem.

I've tested on two phones, and the issue only exists on one of the phones. 
I'm curious about the specs of the phone you've tried, in an attempt to 
narrow down the cause.

It works as expected on a Motorola Droid 2 running Android 2.2.

It does NOT work as expected on an HTC Inspire running Android 2.2.1.

Which phone(s) have you tried, and what OS version is running?

Thanks!

[android-developers] How to "select" and highlight an area of an image in Android Application?

[AndreaNobili]

Hello,
I have to do the following thing:

My Android application have to show an image (for example the human
body), the user can touch some specific part of this image (for
example the head or the stomach) and this part have to be highlight in
some way (for example by displaying a red circle with a radius in the
area, possibly the red circle have to be semi-transparent)

So, do you have some ideas to do something like this?

Reading this tutorial I thought that Canvas could be a solution but I
don't know because I am quite new in Android development and I never
used Canvas before:

[android-developers] Full screen on HTC sensation (qHD)

[GekkeHenkie]

Hi,

I'm creating my first android app, which I derived from the
BluetoothChat example.

However, on my phone (HTC sensation with qHD resolution, 540 bij 960
pixels) the lowest inch of the screen and a few lines at the sides are
not used by the app. See these images:

http://dl.dropbox.com/u/16350275/android/withoutmenu.png
http://dl.dropbox.com/u/16350275/android/withmenu.png

The layout-items are set to fill_parent so I expected something like
this (scaled, but set at right resolution in eclipse):
http://dl.dropbox.com/u/16350275/android/eclipse.png

Has anybody an idea where I should look to fix this? So far I didn't
find any reference in the projectfiles to the screenresolution.

[android-developers] Fragment compatibility package + Android library project + running on API 11+ + DialogFragment in an Activity.

[Nathan Ramsey]

~@Dianne:

The preface:

I'm working on an Android Library Project that wants to use Fragments
and support older API levels, so we're using the Android Compatibility
Library.

I have a UI chunk which is a subclass of
android.support.v4.app.DialogFragment.  When running on devices with
SCREENLAYOUT_SIZE_NORMAL or SCREENLAYOUT_SIZE_SMALL our library
launches a new android.support.v4.app.FragmentActivity which displays
the DialogFragment in its embedded mode. All good so far.

The problem:

I also want to be able to display that DialogFragment in its dialog
mode when running on API 11+. (This is why we're using fragments.)
Since I'm working from within a library project, I do not have control
over the host activity's base class, so it may likely be extended from
Activity, not from FragmentActivity.

Is there a way to display my android.support.v4.app.DialogFragment on
API 11+ inside of a subclass of Activity, not FragmentActivity?

[android-developers] AppWidget update question

[mexibec]

Folks, I got an AppWidget working great, but I need it to be updated
whenever it is visible. It doesn't need to be refreshed if the user is
not looking at it. For instance, if the device is sleeping, or if it
sits on a home screen that the user is not looking at, then it needs
no update. But the second it becomes visible, it needs to be updated,
and then periodically every minute, until it's no longer visible, at
which point it doesn't need any update, and so on.

Setting an intent SCREEN_ION does not work. I don't want to sleep an
alarm when it's not visible (especially not every minute!) Any idea
about how I can achieve this?

FYI, back in the Pocket PC/Windows Mobile era, the Today screen plug-
ins had those features i.e. the plug-ins would be notified when
visible, and periodically afterwards. This is what I'm looking for
because that perfectly fits my apps requirements. Thanks.

[android-developers] Why does ddms heap size not match HPROF?

[Drew DeNardo]

I'm doing memory profiling on my Xoom application. DDMS says my heap
size is "96.133M" and that I have "89.136M" allocated. I did a HPROF
dump, ran hprof-conv, and then loaded the .hprof file into MAT. It
says my heap is 37.3 MB. What gives?

Looking at the output of "adb logcat" while my app is running, it
seems to agree with ddms.

06-22 22:05:59.935: DEBUG/dalvikvm(11875): GC_FOR_ALLOC freed 0K, 3%
free 95699K/98567K, paused 172ms

(note the logcat message I grabbed was not taken at the exact same
time as the hprof -- at this time the sizes reported in logcat matched
what ddms says).

[android-developers] NDK build/awk/extract-debuggable.awk fails on Windows line endings

[Jonathan McCaffrey]

When run on an Android manifest with Windows line endings from a Linux
shell, extract-debuggable.awk fails on the first XML attribute, at
this panic:

if ( _xml_attrib !~ /^[a-z][-+_0-9a-z:]*$/ ) # validate it
_xml_panic("Invalid attribute name: " _xml_attrib);

Changing the line endings to Unix solves the problem.

[android-developers] adb disconnect issue in one round CTS

[lin flinx]

Dear all,

As you know that when doing CTS,  there is a configuration about the
maxTestCount, this params is for CTS host to reboot the device after
maxTestCount reached, see below details
from android-cts/repository/host_config.xml, the maxTestCount is set as 200,
that means in CTS environment, it will send reboot request to device(with
adb command over USB for real devices) every 200 test cases be executed(fix
me if I was wrong)





So when you execute "start --plan CTS" in CTS console environment, all of
more than 2700 cases will start to run on the tested devices which connected
to the host via USB(adb). The phenomena I meet is:
After sometimes reboot(it is randomly), CTS console UI print below message,
then the CTS could not continue to run test case anymore.

CTS_INFO >>> Max ADB operations reached. Restarting ADB...



CTS_INFO >>> Restarting device ...

Device(0123456789ABCDEF) disconnected

Test stopped.


But I still can use "adb devices" or "adb shell" in bash  to connect to the
devices.

and the other case is : If I unplug out  the USB cable and then re-plugin
the USB cable, the CTS can connect the device again and continue run the
test suite.


Does anybody meet the same issues on real devices? and any advices on this
will be appreciated.


Thanks & Best Regards,


Frank

[android-developers] pre-build a android browser plugin

[rio]

I have a problem to pre-build a android browser plugin.

Procedure.
1. Create package/apps/LunaTest directory.
2. Create Android.mk file.
3. The files "LunaTest.apk", "liblunatest.so" and "libysshared.so"
exist in LunaTest directory.
4. Add the string, "LunaTest" into the file generic.mk under "build/
target/product/" directory.
5. Execute "./build_android".


Android.mk is as below:

=
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)

LOCAL_PROGUARD_ENABLED := disabled
LOCAL_PACKAGE_NAME := lunatest
LOCAL_MODULE := LunaTest
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_REQUIRED_MODULES := liblunatest libysshared
LOCAL_CERTIFICATE := platform

include $(BUILD_PREBUILT)

include $(CLEAR_VARS)

LOCAL_MODULE := liblunatest
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(LOCAL_MODULE).so
LOCAL_MODULE_PATH := $(TARGET_OUT_SHARED_LIBRARIES)/plugins/
com.luna.lunatest
LOCAL_PRELINK_MODULE := false
LOCAL_MODULE_CLASS := SHARED_LIBRARIES
include $(BUILD_PREBUILT)

include $(CLEAR_VARS)
LOCAL_MODULE := libysshared
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(LOCAL_MODULE).so
LOCAL_MODULE_PATH := $(TARGET_OUT_SHARED_LIBRARIES)/plugins/
com.luna.lunatest
LOCAL_PRELINK_MODULE := false
LOCAL_MODULE_CLASS := SHARED_LIBRARIES
include $(BUILD_PREBUILT)
=

First, I copyed the shared object files into "/system/lib/plugins/
com.luna.lunatest", but the plug-in didn't work.
So I moved the files into "/system/lib", but it showed the same
result; it didn't work.

The error message is as below:
=
Can't open dex cache '/data/dalvik-cache/
system@a...@lunatest.apk@classes.dex':No such file or directory.
=

Could anyone help me to solve this problem?
