I'm trying to run the Android Notepadv3 app on the Motorola Droid. When I am creating a new note, if I rotate my phone so that the view should switch to horizontal, or if I open it up so the keyboard is exposed, the app freezes and crashes.
I haven't modified the program in anyway from Exercise 3 solution (http://developer.android.com/resources/tutorials/notepad/index.html). Any ideas why this is happening?
I like to develop a product something quite similar to what is shown here in the following link:http://getclicky.com/blog/221/5000-for-an-android-desktop-widget
Could someone provide me with an analysis of what is exactly required to develop a desktop widget for clicky.blog. Please comment and explain in detail.

I was wondering if anyone had any tutorials to get me going. something similar to an alarm that goes off on 2 different occasions on specific dates, these dates and times should be obtained from a csv file or something similar so that i can control when and at what time the alarm goes off.

I also downloaded the Compass application. and it behaves kind of wierd: holding the phone horizonally, I turn around. The compass should keep pointing to the north regardless how I turn. Mine is all over the place. If I point the phone to NE, it does show the N direction but when I try to turn the phone to point to the North it goes all over the place.
This is regardless GPS on or off. I am still at 1.5...
Here's my story.
I downloaded the NotePad tutorial project exercise files.
I created an Android project based on the tutorial files for the completed exercise (located in the Notepadv3Solution folder)
I run the project and bellow is a screenshot of what appears:
It doesn't seem to be working properly.
Could it be because I'm on version 2.2?

View 3 Replies View RelatedI'm just wondering if this is normal: I can go into an app like Google Maps and drop down into street view with the compass view enabled. I'll see that the view will really only point one way and jerk around that one direction as I move it around. I'll then calibrate the compass using the figure 8 method and then street view will work properly. If I then exit back to the home screen and load up say LAYER I'll have the same problem. The compass will point in one direction and jerk around it until it's recalibrate again. It's more of an annoyance really as I basically have to recalibrate it every time I open up an app that uses it. Just wondering if others are having this issue. I've talked to a few i phone friends and other than the occasional recalibration they don't seem to have this issue.

Is 'm' a java thing? Does it stand for mobile? mixed?

I'm back on the forums, FINALLY! I finally got fed-up with dealing with Verizon and their rediculas prices. I had 2 phones on my 700 Family Share plan and it was nearly $160 with NO extra features. Just phone. Not internet, no texts, basic NON3G phone.. Looked into other carrirers and found Sprint... What is that? It's HUGE!... It's the EVO 4G. I'M THERE! I am spending the same each month as I was with verizon, with a Smartphone plan. I love it!
Fallow me on the HTC EVO 4G section! http://androidforums.com/htc-evo-4g/
IMPORTANT UPDATE: 04/03/10
I had to make a choice between my Droid Eris and purchasing a vehicle for the future. Of course, the vehicle won; so I no longer have the Eris *pout*. I hope everyone has fun with the future updates and conversations regarding the Eris and 2.x updates. I thank everyone that has helped me out and the 50+ who thanked for this Thread.
So I've searched high and low and can't figure out a good (idiot proof) tutorial for setting up adb? Can someone put one together (for windows) or point me in the right direction? I currently use terminal for almost everything, but most people write their tuts for adb. If you write one, please start simple and at the bottom and work your way up.

I was messing around yesterday, and tried hitting the Calibrate button like 50 times FAST AS HELL and I got the compass to appear! Doing it the normal way didn't do anything, as the phone would just repaint the screen with the fake phone showing you how to rotate it.After a few rotations, it turned green. I was like, wow, that was easy...until I tested it. My phone now refused to go to landscape at all!! So I tried it again. After another 50 taps, I went throught the same motions, got the red compass folks were complaining about in another thread and tried the solution that worked for some by deleting the market Compass app I got months ago. I went back to settings and...nope, still needs 50 taps and still got a red compass. I did a reboot and a battery pull, and same result. I can no longer get into landscape mode, EVER!!! The only way to get into landscape is if I am playing a game or something, but rotating the phone for web surfing or texting just doesn't work.
View 9 Replies View RelatedWondering how many of you have a compass that is accurate through its entire travel? Mine heads in the right direction for about 270 degrees (rotating the phone) and the other 90 it is off by about 30 degrees. I have checked out 4 or 5 others in stores since launch day and they behave exactly the same. I also see this behavior using street view.
View 5 Replies View Relatedi've been a (mostly) happy user of the milestone, as it is called over here, but in the past few days i noticed a problem.the compass in the phone is not only off, but virtually broken. it detects a constant reading "to the upper left", which simply overrides the earth's magnetic field. so, no matter how i turn the phone, north is always between one and two o'clock. by using the amazin tricorder app, i was able to find out that the magnitude of the reading differs significantly depending on the orientation of the phone, reaching almost "100" in the max, and about "65" when the phone is 18o turned. so i cleverly deduced that the magnetic flux sensors are still somehow active; but still, they turn out to be useless to me if they show a constant reading no matter.

View 3 Replies View RelatedI am trying to create an android app that will let me display images fullscreen with next and previous buttons on top to change between them.
Can anybody point me to some tutorials where i can find instructions on something similar?
If not, what is the best method to use to get the images into the app? I have tried several ways from creating object classes for the images and instantiating it with a drawable in each using the Bitmap Factory to return the image but that won't work.
I am a beginner to android and could really use reference material but can't find anything useful that covers this subject.
