[android-developers] Native code is being called successfully but not executed properly
hai folks,
In Android , Native code is written as follows.
JNIEXPORT void JNICALL Java_com_android_Test_show(JNIEnv *env, jobject
obj)
{
printf(THIS IS TEST);
}
JNIEXPORT jint JNI_OnLoad(JavaVM *vm, void *reserved)
{
JNIEnv *env;
JNINativeMethod meth;
jclass k;
jint r;
r = (*vm)-GetEnv (vm, (void **) env, JNI_VERSION_1_4);
k = (*env)-FindClass (env, com.android.Test.show);
meth.name = show;
meth.signature = ()V;
meth.fnPtr = Java_com.android.Test.show;
r = (*env)-RegisterNatives (env, k, meth, 1);
return JNI_VERSION_1_4;
}
JNIEXPORT void JNI_OnUnload(JavaVM *vm, void *reserved)
{
JNIEnv *env;
jclass k;
jint r;
r = (*vm)-GetEnv (vm, (void **) env, JNI_VERSION_1_4);
k = (*env)-FindClass (env, com.android.Test.show);
(*env)-UnregisterNatives(env, k);
}
While executing on Android the following messages are obeserved in adb
logcat.
JNI ( 524): Trying to load jni .so
I/System.out( 524): /system/lib
D/dalvikvm( 524): Trying to load lib /data/libjnilibs.so 0x433f22d0
D/dalvikvm( 524): Added shared lib /data/libjnilibs.so 0x433f22d0
I/ActivityManager( 50): Displayed activity
com.android.helloactivity
But THIS IS TEST is not being displayed, which is displayed in
native code.
There are no errors regarding loading shared library and calling
native code.Then why is the message is not displayed in logging.
Am i doing any mistake.If JNI_OnLoad and JNI_OnUnLoad are not
implemented i am getting errors in Logging.If i do as above i not
getting that native code message.
Any help would be appreciated highly.
Regards,
-Siva.

[android-developers] Multiple data for an intent
Hi All, I was just wondering if it is possible to give the intent a set of data, instead of just one. A particular scenario where this could be applicable would be a music application. You select a list of songs, and pass all these data (file path) to the Music Player's application. Another scenario: You need to plot more than one address on the Google Maps. You launch the application with a set of data for the intent. Is this possible??

Hi Ajeet, Thanks for the reply. This is great information, but unfortunately does not address my question.

[android-developers] Re: Hmm... at last ADC2 is out of our way ... tell about your app and experience
For ADC2 I created BabelSnap! for the Travel category. You use the device's camera to snap a bit of text, whether from a public sign, a menu, or newspaper, etc. The image is fed through an OCR, and the resulting plain text can be translated to any language. http://babelsnap.com/ (Yes, the demo video has the world's cheesiest and generic music. :-) Maybe I should have left it with no audio! ) I attended GoogleIO at the end of May where I first learned about ADC2, and received one of the Google Ion devices. Substantial prize money plus free device -- I could not ignore the opportunity to participate. That prize money could afford me some more help, and maybe some better OCR that recognizes non-latin characters, and maybe help pay some bills too! :-) I built BabelSnap in about 5 weeks. I had all the basic stuff functioning in about half that time. The other half I spent learning the idiosyncrasies of an android app -- like what happens when someone presses the back button or home button while your background thread (not your UI thread) is still doing processing... And having to do manual garbage collection when manipulating/copying large images from the camera And the camera API itself -- could use some improvements in documentation, and in the API itself. (That is another topic.) The version of BabelSnap I submitted to ADC works well if you can acquire a good image for the OCR. But this takes a bit of practice, holding the camera steady while focusing, framing the text properly, and hitting the shutter button all at once. I want it to work a little more casually, and not require so much practice. The revision I am currently working on will permit the user to assist in picking out the relevant bits of the snapped pic that contain the text they want to translate, by simply touching/dragging across that part of the image. In all, I have a very positive experience in creating an Android app. I am impressed with what I could assemble in such a short period of time. As for the deadline and submitting updates. Google *had* the draw the line somewhere. I could have gone on indefinitely fixing things up. I was glad to have a hard deadline, and sad to give up some functions that I wish could have been present for the judging. I do like the approach of continuing to make revisions available in the Market independent of the ADC submission. I also think Google has the right approach in trying to cultivate new mobile app ideas -- everyone loves a little competition. And Google seems serious; they've put forth a great deal of cash and hardware. Good luck to all. I look forward to trying out your new apps. -broc On Sep 2, 12:41 am, Lout lout.r...@googlemail.com wrote: While you developers relax... would you mind sharing what apps to expect through this challenge.. and anything else you wish to share about ADC2 submissions... well anything including the fact: 'thank God, no more sleep less nights'!

[android-developers] Re: Ethernet / IP over USB connection?
Usb ethernet dongles will not work at all, the current android phones are usb devices themselves, and do not (yet) support connection to usb devices, only to usb hosts. The usb through to pc idea is workable to an extent, but it will likely only be custom applications on the phone that are able to use it, as the stock system images don't as far as I know support adding additional network interfaces - you'd be limited to doing something like ppp or http proxy over an adb port forward, unless you are are allowed to change the system image to add kernel modules and associated configuration.

[android-developers] Re: Android WVGA support
Supporting a wider variety of hardware has been an ongoing processes, and was already started with 1.5 with the introduction of soft keyboards and corresponding mechanisms for applications to declare they require hard keyboards etc. This will continue after Donut as well. We are not going to drop a hardware requirement without having a mechanism for applications to specify that they need the hardware and a strategy for grand-fathering existing applications into the filtering.

Another possible one -- call startActivity() to start a new instance of your activity and then call finish() in the current instance.

Lee, Take a look at android.widget.DatePicker and android.widget.TimePicker source codes, and you'll notice that they're using date_picker.xml and time_picker.xml as they layouts. So far so good! Now take a look at date_picker.xml source code and see those com.android.internal.widget.NumberPicker components. The same story for time_picker.xml. Even the worse is that DatePicker and TimePicker are both referring to NumberPicker component in their codes. So by extending these two classes, I can't see a way to do what I want. I have to somehow deal with those internal API, unless I copy the whole code and deal with my own version of DatePicker/TimePicker/NumberPicker from scratch. Correct me if I'm wrong...

Dianne, In the blog post can you cover how to produce one app which will run on cupcake and donut and support multiple resolutions. As I understand things at the moment developers will need at least two versions of the same app listed in Market to cover both bases; One with minSDK=4 and the supports-screens manifest tag and a separate one for cupcake devices because cupcake won't run apps with minSDK 3. If there is also a lite paid for version you're then into 4 app listings for the same app (lite, paid-for, multi-resolution lite, multi-resolution paid-for), which seems like its' going to be a it of a pain.

[android-developers] Re: Threads and Screen Orientation Change
Hello,
From the conversation above, i understand that having a static reference to

callbacks to the activity (which can then render stuff on the UI).
However, It would be helpful, if someone can also provide an example of
using Handlers.
For my understanding so far, I am posting some pseudo code below. Please
feel free to correct me/enhance the code, so that i may understand this
concept better.
I can create a static handler reference in my activity class like this:
private static MyHandler handler = new MyHandler();
My handler class may have the following structure (assuming that MyHandler
is an inner class of my Activity class):
public class MyHandler extends Handler
{
public void processCallConnectedEvent ( Message m)
{
// do stuff here..show a dialog that displays Call Connected on the
Activity's UI
//sleep here for sometime, say 2 seconds..
// dismiss the dialog.

And you can make your show/dismissDialogSmart 'static'. Then you never
need a reference to an Activity at all. Just call
OrientationAwareActivity.showDialogSmart(id)

Brilliant idea!!! That's the solution!
And you could abstract it out into a sub class like this (I wish
showDialog/dismissDialog weren't marked as final!):
public class OrientationAwareActivity extends Activity {
private static OrientationAwareActivity ACTIVE_INSTANCE;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ACTIVE_INSTANCE = this;
}
@Override
protected void onDestroy() {
super.onDestroy();
ACTIVE_INSTANCE = null;

public void showDialogSmart(int id) {
if (ACTIVE_INSTANCE != null) {
ACTIVE_INSTANCE.showDialog(id);
}
}
public void dismissDialogSmart(int id) {
if (ACTIVE_INSTANCE != null) {
ACTIVE_INSTANCE.dismissDialog(id);
}
}

[android-developers] Re: onReceive not triggering for SEND / image
I know i'm bumping this, but i really think it's something simple i've
missed. Trying to avoid definitions i might be using incorrectly:
This is what i have:
An app that turns up in the share menu of the gallery.
Selecting my app starts it as if you would start it normally
This is what i don't have:
A way to react to the image i was looking at: i do not know where to
define code to do stuff with the picture.
Just a small nudge in the right direction is enough hopefully,
please? :D

SEND is an activity action. All you need to do is have it in your manifest

Example use case: Suppose i am maintaining the state of a call, and providing callbacks to the UI by invoking sendBroadcast with the relevant intent. Similarly, my underlying business logic can send broadcasts to the activity that has registered for receiving it on certain events ( like call connected, connecting, timed out etc).

You can always log the content and use LogCat to view the ouput.
Or you could create a test Intent for the purpose:
public class DumpArray extends ListActivity{
public void onCreate(Bundle savedInstance){
super.onCreate(savedInstance);
setListAdapter( new ArrayAdapterString(this,
android.R.layout.simple_list_item_1, myArray);
}

[android-developers] INCORRECT Download Count Vs. Active Install Count
What is the deal with this market not registering when people uninstall, then promptly reinstall? I am 100% confident this is occurring as my users seem to need to uninstall the app before upgrading due to a widget service that continues to run using the old code AFTER a user upgrades to a newer version, causing errors. Uninstalling, then reinstalling fixes any errors as the service gets stopped in so doing. My MAJOR concern is the fact these users, who I am in contact with and through server logs, clearly are reinstalling promptly following their uninstall yet each new release I get an instant 20% less users in the active user base. This is causing the app to not only lose traction in popularity, it is just a bunch of bullshit. Fix this or stop penalizing people until you figure this shit out. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: MyTouch Lag Problems
Hey there. I wanted to follow up and say that I haven't heard back from any of my users that have the myTouch and toggling/turning off the location services to see if it made a difference. However, I came across something in my code which may be at least part of the problem. In WordUp! the user spells out words by tracing their finger across the letters which are arranged on a square grid. I handle onTouchEvent(MotionEvent event) calls to my view to determine when the user first starts selecting, when they are dragging their finger, and when the let up to do the appropriate drawing and recording of letters during this gesture. One thing I had not taken into consideration is the large number of onTouchEvent calls I would get while the user is moving their finger while it is pressed down. I only needed to care about when their finger enters the bounds of a new cube, and record and invalidate a dirty rect to redraw that portion of the screen. However, I was doing this work on every call to onTouchEvent which was invalidating my dirty rect many more times than it needed to. Once I accounted for this, the drag gesture is a lot more responsive. I haven't confirmed that this fix addresses the lag issues people have seen using my game on the myTouch, but I'm very curious to find out.

[android-developers] Re: MyTouch Lag Problems
Another thing you should probably consider -- the MotionEvent may contain more than one movement, as part of the historical data. So, especially if you have a little overhead in handling events, if someone moves their finger quickly you may get a single motion event with some historical points inside of a box but the final one outside.

I wanted to follow up and say that I haven't heard back from any of my users that have the myTouch and toggling/turning off the location services to see if it made a difference. However, I came across something in my code which may be at least part of the problem. In WordUp! the user spells out words by tracing their finger across the letters which are arranged on a square grid. I handle onTouchEvent(MotionEvent event) calls to my view to determine when the user first starts selecting, when they are dragging their finger, and when the let up to do the appropriate drawing and recording of letters during this gesture. One thing I had not taken into consideration is the large number of onTouchEvent calls I would get while the user is moving their finger while it is pressed down. I only needed to care about when their finger enters the bounds of a new cube, and record and invalidate a dirty rect to redraw that portion of the screen. However, I was doing this work on every call to onTouchEvent which was invalidating my dirty rect many more times than it needed to. Once I accounted for this, the drag gesture is a lot more responsive. I haven't confirmed that this fix addresses the lag issues people have seen using my game on the myTouch, but I'm very curious to find out.

[android-developers] Re: Using Broadcast Receivers
They are also WAY more overhead than just doing things in the local process (you need to do an IPC to the system, it needs to schedule the broadcast, then do an IPC back to each application that is receiving it, copying all of the data in it each time). For stuff happening in the local process, Handler and direct callbacks are the preferred approach.

[android-developers] Re: how to get events out of a service.
Best: you probably don't need to have the service running in a separate process from your code, so use the LocalService api demo model, and just do direct calls to Java objects both ways without dealing with aidl at all.
