[android-developers] With security keyguard active transition between activities is weird
Hi, maybe someone has an idea, i'm looking for an answer for ages but no luck. I have my main activity A and when the user presses a button i open another activity B. But when this happens B doesn't just appear on top of A: - A disappears - secure keyguard shows up - B appears And when i get rid of B the same thing happens. This is annoying because there's a lot of flickering with no real purpose on the screen. Is there any way to achieve direct transition from A to B while keyguard is active without merging the 2 activities into 1?

[android-developers] Can't disable keyguard anymore
Hi,
has something changed in the latest OS update (Android 2.2.1, Nexus
One) about disabling keyguards? I have an app that has an alarm
feature and wakes up the phone + disables the keyguard; the keyguard
disabling doesn't happen anymore. Here's what i'm doing:
private final void unlockScreen() {
final KeyguardManager km = ((KeyguardManager)
getSystemService(Activity.KEYGUARD_SERVICE));
if (km.inKeyguardRestrictedInputMode()) {
final KeyguardLock kl = km.newKeyguardLock(KEYGUARD_SERVICE);
kl.disableKeyguard();
}
}
private final void wakeScreen() {
final boolean dim = sPref.getBoolean(Config.ALARM_DIM, false);
final PowerManager.WakeLock wl = ((PowerManager)
getSystemService(Context.POWER_SERVICE))
.newWakeLock((dim ? PowerManager.SCREEN_DIM_WAKE_LOCK
: PowerManager.SCREEN_BRIGHT_WAKE_LOCK)
| PowerManager.ACQUIRE_CAUSES_WAKEUP, TagToDoWake);
wl.acquire();
new Handler().postDelayed(new Runnable() {
public void run() {
wl.release();
}
}, 2);
And i'm calling them in this order:
wakeScreen();
unlockScreen();
Thanks,
Teo

[android-developers] Why would SQLiteOpenHelper.onUpgrade fail?
Hi, every time i increase my database version and push the upgraded app to the users, something weird happens.. For some it works perfectly fine, and some report crashes (including through the Market's reporting system) caused by the lack of table columns i just added in onUpgrade. If you want to see the method: http://code.google.com/p/tag-todo-list/source/browse/trunk/Donut/src/com/android/todo/data/ToDoDB.java#136 I can't spot any exceptions that appear in onUpgrade. What i'm currently doing to bypass these problems is intercepting the exceptions where the new fields are invoked for the first time and then calling onUpgrade 'manually', which is kind of dirty. Does anyone have any idea what might be happening? Thanks, Teo -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Bringing an Activity to front
Hi, i have multiple instances of the same activity, is there a way to programatically bring one of the instances to the front? I've read some existing threads and it seems there's no way to do this... My specific use case is of a Snooze/Dismiss type of screen. The problem would appear when the user sets 2 alarms close by: - first alarm is triggered, so first instance of the activity is created - user doesn't dismiss the alarm - second alarm is triggered, so the second activity instance is created and comes to the front - user doesn't dismiss this either - first activity instance reminds the user about the first alarm (sound can be played, but the UI is still somewhere in the background) Any suggestions?

[android-developers] Moving app to SD card
Hi, as stated here: http://android-developers.blogspot.com/2010/07/apps-on-sd-card-details.html , even if an app is installable on the SD card, the private data files remain on the phone... If this is true, my question is: are users aware of this? This would mean that moving/installing on the SD card means only the app installation is mobile, and not the database, for example. Do you know more about actual use cases for this 'moving to SD card' feature? I'm trying to figure this out because more and more users are asking me to allow it to be movable to the SD, but i don't want to create false expectations (e.g. user changes phone, keeps SD card, but loses his 'stuff'); Thanks, Teo -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Changing project build target
This question might have been asked a while ago (in fact i asked it too but still no answer :). Let's say i'm changing the project build target from Android 1.6 to Android 2.2 and that the android:minSdkVersion attribute is changed accordingly. What will happen to my current users who don't have Android 2.2? Will they receive the update through Android Market automatically? Will it try to install the app and fail, but the current (already installed) version will still work? Will the failure break the app?

[android-developers] Re: Device Seeding Program for Top Android Market Developers
Hi guys, i don't want to be a smart-ass or anything :) It may seem to people looking at this thread that some are complaining which i don't think is true.. Thanks Google for doing this btw! Must be a logistical nightmare to deliver so many phones at once, especially in Europe too, which, considering we're talking about the Nexus, is kind of cutting edge because otherwise Google doesn't directly sell phones in most of our countries. But precisely for this reason it's probably very hard for us to have the official status of every phone, so i think posting updates or about our own situations, in this thread, is understandable because we know more about what and when to expect... Just my humble thoughts :) P.S. I think it was done before, but i'll ask for it again anyway: if you get the phone (especially in the EU) from the seeding program (and not from ADC cause apparently there was some confusion about that) please remember us and let us know :) On Apr 12, 9:32 pm, Mirko Nasato mirko.nas...@gmail.com wrote: Yeah why don't you two launch your own free gift program, only to call it off some time later?

[android-developers] 'Squeezing' a button on the right side
Hi, you probably heard similar problems before but i can't figure out how to do this programatically. I have a vertical layout with FILL_PARENT on both dimensions. In it i have multiple horizontal layouts with FILL_PARENT width and WRAP_CONTENT height. In each of these horizontal layouts i want to put a checkbox on the left and an ImageButton on the right. The problem is i can't stop the checkbox from growing to the point of pushing the ImageButton out of view.. (same thing happens when the checkbox has FILL_PARENT or WRAP_CONTENT widths). For individual stuff i managed to do it in the XML layout very easily: ...something... android:layout_width=fill_parent android:layout_height=wrap_content android:layout_weight=1 / ...something... android:layout_width=wrap_content android:layout_height=wrap_content / Same thing doesn't work programatically though, and i've tried other gravity, weight, layout combinations..

[android-developers] Do i need to call DatabaseHelper.close()?
I have a DatabaseHelper instance for db stuff. Until now i kind of had a mess of everything but made it a singleton so it won't need to be created over and over again. The same object is used both in the fullscreen app and in the widget. The thing is, in case the user also has my widget on the home screen, when the fullscreen app is closed i wouldn't want to close the dbHelper in onDestroy. My question is: does Android or the garbage collector do all the necessary stuff to release the memory in case it *isn't* used again?
