I have developed and tested my app on the emulator, and now want to install it on my HTC device. the apk installs successfully, however my database is not going with it. I have created my database using sqliteman browser b/c I have to insert a bulk data before the app starts. I have four tables in my db and call each in different activities and created all on the sqliteman. after the data is inserted I pull back the db onto the data folder of the emulator. it works perfect on the emulator but failed on the device. when I try to pull my db on the real device, it shows access denied problem

Ok, I've tried two examples of AlarmManager- one from the commonsware website, and one from the manning website. The code I am currently working with is from the manning website : [http://unlocking-android.googlecode.com/svn/chapter8/trunk/SimpleAlarm/][1] There are two classes, AlarmReceiver and GenerateAlarm. Anyone have any idea why the toast will not display in the emulator? I was thinking that it was because I am located in the Eastern Time Zone and it uses UTC, but I have fiddled with different things and none of them seem to work.

I setup Hello Android sample app on my Eclipse ( Windows XP). ADT got installed correctly. All post installation config also looks good. I setup HelloAndroid project.
I run first time . It was successfully run and connected to emulator , produced desied message on emulator.
What happened , when i tried to run same program again it stopped working at console trace ( see below console trace). I tried to reset Adb from debug view. Also tried to kill Adb from command line. I completely exited from Eclipse and restarted. At last completely rebooted PC but no luck. I never changed my code a bit after running successfully first time.
Hello Android stops at following message.
[2010-07-08 16:08:59 - HelloAndroid] Starting activity com.example.helloandroid.HelloAndroid on device
[2010-07-08 16:09:02 - HelloAndroid] ActivityManager: Starting: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.example.helloandroid/.HelloAndroid }

The same code that displays the lists running on the emulator doesn't run on the mobile (Motorola Milestone). I'm using the same android platform (2.1-update).
Inbox Code...
TextView subject_textview = (TextView)rowLayout.findViewById(R.id.subject_textview);
subject_textview.setText(email.getSubject());
String body_hint = " - " + email.getBodyHint();
TextView bodyhint_textview = (TextView)rowLayout.findViewById(R.id.body_hint_textview);
bodyhint_textview.setText(body_hint);
String sender_name = get_sender_name(email.getSender());
TextView sender_name_textview = (TextView)rowLayout.findViewById(R.id.sender_textview);
sender_name_textview.setText(sender_name);
TextView date_time_textview = (TextView)rowLayout.findViewById(R.id.date_time_textview);
date_time_textview.setText(email.getTime());

I'm looking to be able to use my Galaxy Tab as a second PC display. I've been searching for hours for a way to set this up and I've found a few solutions, but so far they've all been lacking. I'm hoping others might have some experience or thoughts on the subject. Here's what I tried or looked into so far:
iDisplay - Available on the Market. So far about the only solution that works, but it's god awful slow. If you try to use a browser with a couple tabs open, it practically stands still. It also disables Aero on Windows 7.
Screenslider - Available on the Market. Disables Aero. Doesn't like web browsing, FF and IE won't redraw when clicking anything (links, Java objects, tabs, etc).
Air Display - Available on the Market. Disables Aero and DirectX. This one was extremely responsive, but you just can't do anything on it. Not compatible with FF9 or later and can't handle dynamic web content.
Remote View - Available on the Market. Disables Aero and Background. Honestly, I don't even remember why this one didn't work. Pretty sure browsers just froze. Have to jump through hoops on their website to even get the server.Splashtop XDisplay - iOS only. Looks like it would be perfect, but it's not on Android yet. They said they were working on it 6 months go, so I'm not holding my breath.
Virtual display + a VNC connection - This is the most promising, so far. The idea is to use software to create a virtual display that's normally hidden, then use a VNC server (that can deal with individual displays) to send that extra display to a VNC viewer on the Android device. It seems like this would be the most responsive, plus you shouldn't lose Aero or specific applications since you're essentially just sending out a video stream (I think). Some apps even combine the virtual display and VNC server into one. In reality, actually setting this up has been a royal PITA (due in no small part to my complete lack of experience with this sort of thing).
Other Android RDP or VNC apps that have this sort of functionality built in?

I just used this getDeviceId() to retrieve the unique id of the phone, but in the emulator it gives 00000000 when I try to display it. I know it makes sense to do that but can I spoof a device id for testing purposes. I need to setup about 4 -5 android devices in my emulator to check the functionality of the app that I have written, and the entire app revolves around the unique id of the mobile device. I just feel, maybe it should be there in the DDMS but I am not able to figure it out.

Is there a way to check if our code is running in the emulator vs a real device? I'm using a Map View which requires a signing key. I'm using the signature of the eclipse debug key when running on the emulator, but this won't work when I build a release version. I think I need to have a check to see if I'm running on a real device, and set it to the real release key at that time.

I am trying to actually simulate a vibrator device inside the emulator .A timed_output driver for the vibrator was created and i am able to access the node at /sys/class/timed_output/vibrator/enable that is specified as THE_DEVICE in the vibrator.c file at hardware/ libhardware/vibrator/.The driver is tested to work from the kernel below. I ran into some issue while trying to invoke the driver from a user level app.I just added these two lines and created an app.
vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); vibrator.vibrate(10000);
when i created an .apk and ran it i could see the following messages in Logcat.......................

Is this possible to do using the android emulator? when i googled this requirement, i came across SensorSimulator...But,this software shows the acceleration,magnetic field and temperature values... It doesnt display the co-ordinate values....

I'm using the 1.5 SDK. I read in 1.0 that rotating the device would cause onCreate() to be called in our apps (possibly recreating the entire app?). Is there a way to test rotating the device in the emulator? I just want to see what happens, I don't have a device to test this. Will the behavior be the same for 1.5 as it was in 1.0?

Is there a simple way to detect that your code is running on the android emulator and not on a real device? I want to work around differences between emulator + real, e.g. with respect to network connectivity detection.

Did anyone encounter this problem? Particularly, I have a dialog style themes for a few activities and these come up as expected on the emulator, but are full screen on the device. The theme I a using is actually an extension of the basic dialog theme (Theme.Dialog). I did not check with the original one.

I tried several times but it is still not working.

Is there a way to change/add the device model in Android emulator?
If I try to get device model programatically, it always return "android-sdk" or "sdk" in emulator.
I want to set the real device name in emulator for testing purpose.

I am working on a compute intensive app for Android. I do not have any device yet to test performance. However, the performance on emulator is a bit slower than expected. I see an old question about some estimation of emulator vs device. What are your experiences while developing apps with recent SDK Froyo/2.2. Is performance observed on emulator is slower than actual device. Please share your experience and the specs of your dev machine and mobile devices, both.
