I need to create a random character generator that return a single character. The character should range within the letters of the alphabet, numbers 0 through 9, and some characters like.

The problem is that nothing appears in my textview after shaking the phone.
I'm trying to create an android application which will generate random series of values (integer numbers in this case) in a given range (but NOT equal between them) and display them in a simple TextView.

View 2 Replies View RelatedThank to previous replies, and with a major inspiration from http://insanitydesign.com/wp/projects/nehe-android-ports/ , i started to build a simple Tile Generator for my simple 2D zelda-like game project.I can now generate a map with the same textured tile, using 2 for(..) imbricated iterations to draw horizontal and vertical tiles, and got some basic DPAD key input listeners to scroll over the x and y axis.but now im running into my first performance problems, just with one texture and one model.When trying to build a 10x10 map, scrolling is fine and smooth.When trying with 50x50, things get worse, and with a 100x100, its way unacceptable.Is there a way only to tell OpenGL to render the 'visible' part of my mapset and ignore the hidden tiles? im a totally new to this.

I've had my Incredible since 4/28, and everything has been working smoothly up until about last Thursday night when it just restarted out of the blue while I was listening to music. Then right after it booted up, it restarted again, then again about seven more times. I got fed up and took out the SD card and it seemed to stop after that, so I haven't put the SD card back in since then.
Just now, Wednesday, about a week later, I was browsing around on the internet and all of a sudden, it restarted, and then again, and again, and again. I've read that it is because of poor signal strength or something like that so I had just enough time to put it in airplane mode before it restarted again.
Side note, that theory about it being caused by poor signal seems to make sense because the first time it happened to me I was out of town in a city that gets very bad coverage with Verizon, and now today when it started happening again was at my house where for some reason I get very bad service with the incredible, my old phone worked perfectly fine in my house but the incredible gets terrible service, and so does my brother's Droid. In fact, about two weeks ago I got my first dropped call on Verizon in about three years, and it was in my house.
So anyways, I decided to put it in airplane mode, and just after I put it in airplane mode it restarted again. Then when it booted back up my Helix Launcher 2 home screen went back to the standard Helix Launcher 2 icons, I go into my messages and everything is gone, my contacts are all gone, everything is gone. I go to the app menu and all my apps are still there, but when I start up an app, all the custom settings are default now. I went into the settings and my accounts are all still there. I click on internet and I get a terms of service agreement, it's as if I am booting it up for the first time, but for some reason my apps and accounts are all still there.
I turn airplane mode off thinking it might have something to do with it not being connected to my google account, and I restart it again and everything is still gone. I don't know what to do, has this happened to anyone before? I feel like there should be a way for me to get this stuff back since my apps are still there and my accounts are still synced, but random things are missing like my contacts and messages etc. This is really starting to get annoying, I have insurance and everything, but I really don't want to exchange it for another one because I've read that other people who have had there phones replaced have still had the same rebooting problem, even after going through multiple replacements.
I am initiating the design of an application that would require an Android phone to connect to another Android phone via Ad-Hoc networking with or w/o security. I would like to know if Android supports ad-hoc networking. I would also like to know what is the average range of the wifi signal from an Android handset point-to-point with no obstructions. I cannot find any information about this on the web.

Is this just normal because of the antenna size on the droid or is there something I can do to improve it? I feel like I have to be right next to the access point to have a good connection.

View 2 Replies View RelatedI am trying to resolve following task: smooth change of brightness from 100% to 0%, but can't gain effect of smoothness. Want to emphasize that I am using following approach of brightness change. The recommended one.
WindowManager.LayoutParams lp = window.getAttributes();
lp.screenBrightness = floatPercent;
// 0 - 1 window.setAttributes(lp);
Well, it obviously works, but not smooth. I will describe logic. I have a thread that changes brightness:
while (isRunning()) { Thread.sleep(sleepTime);
spentTime+=sleepTime;
view.post(new Runnable() {
public void run() {
changeBrightness();
} } );
}
We have duration of brightness change, for example 10 seconds. I calculate next value of floatPercent (see code snippet above) the way, sleepTime should always be less than 50ms. So looks like it had to be smooth. But I always get not smooth transition. It relates specially the range of 0% - 5% of brightness. Smoothness is completely lost on this brightness range. What can you propose?

View 2 Replies View RelatedI have just recently moved from Nokia E75 to HTC Desire, and there are lots of stuff on the E75 that I will never miss... But, there are a couple of things I am missing very much, tho. One thing was a very clever feature that saved a lot of battery... On my HTC Desire I have to leave wlan enabled at all time for the phone to utilize wireless at all, and I can see that it's consuming approx 20% of the battery power - even if no apps or widgets are accessing internet.
But on the Nokia E75 it's very different... The wlan is switched off by default, so whenever an application on the E75 needs a data connection (internet), it will quickly enable wlan and check to see if there are any networks nearby it can access, and then disable it again if it doesn't find any. (If no wlan access point is detected, it will go online using the mobile data connection automatically instead)
I have a full-screen TextView holding a long Spanned that requires scrolling. The TextView's getLineCount() gives me the total number of lines used for the entire block of text but I'd like to know how many lines of text are currently visible on the screen.
Or, better yet, is there a way to figure out the range of lines currently visible on the screen? For example, as the view scrolls, can I tell that lines 20-60 are currently visible?

My home wireless network has always worked with my Eris until I updated to 2.1. I can get it to connect once, but after a few minutes, it disconnects and when I go into the wireless settings, I see the status as "not in range, remembered" even though I'm right next to my wireless router.

View 4 Replies View RelatedI'm going to ask a shot version of my question first because, as I was typing out my thorough explanation below, I realized that I had seen a setting that I believe fixes my problem but I cannot remember where it is or how to get to it. In short, the problem I am having is that Non-recurring events (one time appointment) that are in the Google Calendar online are not showing in the Moment calendar app. There was a Settings Page not sure if it was in the main OS menu or the Calendar menu that gave you the option of choosing to show events "before" a certain date and to show events "After" a certain date. You repeatedly tap the two "before" or "after" options and the dates would move further back in time and further forward in time respectively creating a date range.
Non-recurring events, obviously, continue to show for years prior or in the future but Non-recurring one-time events outside of a "range" of a time period do not show. Does Anyone know what the setting I am referring to and how to get back to it?? If not, perhaps my more thorough explanation of my problem and what I am trying to accomplish below might help me find the display before this date/after this date setting that I cannot find again! (longer explanation/description follows below): We have a Moment and an EVO and we are both new to Android but it appears I am only having the problem with our Moment. Though we are new to Android and the gmail sync, I am very comfortable with the sync process and working with Google Calendar online or on the phone and the settings for forcing a sync, choosing which calendars to display, etc. I did some troubleshooting of the problem and this is what I have figure out here goes:
It appears that the calendar on the Moment is only showing recurring events birthdays, anniversaries anything where the event is set to recur some time in the future. The non-recurring events a random party, a random doctor's appointment does NOT show on the Moment Calendar app! I prefaced my issue with being comfortable and familiar with the Google calendar operation because I am certain that the events are in the Google Calendar online. If I change the one-time event to a yearly recurring event and force the phone to sync then WHAM BAM the now recurring event shows in the Moment calendar app. Remove the recurrence and go back to the one-time doctor appointment, sync, and disappears again! The other odd thing is that "old" Non-recurring events that have already passed do seem to continue to show on the Moment calendar app for about a month. In other words, stuff back to about a month from today (today 7/20) DOES SHOW even if non-recurring but anything older than a month does not show.
Now I can Understand why if you had a doctor's appointment on May 20, 2010, that that even should NOT appear on either your Google Calendar online OR your Moment calendar app for May 20, **2011** because that doesn't make sense. However, it DOES make sense and is important to be able to go back to May 2010 and ask,"what day was that appointment with so-and-so company?" and you scroll back in your calendar to see the name of the company or "In February, 2010, did our son or daughter see the doctor? and you scroll back a few months to see that your son and not your daughter went. The Google Calendar online does NOT automatically purge older events, they are all visible online back yearsand years. Why is the Moment "purging"/not displaying non-recurring events on the phone that are in a range of about 1 month old to about to happen in a month?
I noticed this same issue with my HTC Hero, and then it seemed to go away. Now I've noticed it again.
The issue is this: I have around 2700 songs on my SD card, all in a folder called Music, and they are arranged, quite logically, by artist and album under that. Unfortunately, when I put the music application on random, it seems to get stuck on 4 or 5 artists (and sometimes within those artists, one particular album) and play those almost exclusively, with only an occasional diversion to some other artist. At one point it was so bad that a. it played one particular song 6 times in a 4 hour period, and b. I got so tired of one of my artists, I deleted it entirely!
So, is this a bug with the built in music player? Is it because of the amount of music I have? Is it because of where my music is stored? Has anyone else had this problem? (Or does Android OS just have an affinity for The Byrds? )
Are there any other music apps I can try? I tried Simply Music, and it did work much better on the randomization, but it hung for a few seconds several times (for no discernable reason) and it is very slow to load.
What is the range of wireless tether
View 2 Replies View RelatedI got the Hero on 3UK yesterday. As soon as I booted it up it found a number of wireless networks and I was able to connect to my BeBox with no problems. Later on last night and continuing today, it can't find any networks in range. It shows the BeBox as 'remembered' but not in range. Even tho I'm obviously sitting near it. I've rebooted the phone today and no change. I installed the Fonera application yesterday and thought it might be causing problems so disabled it and still the problem was there.
