So I have a physical chart of time intervals (minute:second) which map to point values (for example: 9:59-10:10 = 59.7) and I need to write a program that tries to find out the point value for a given time (such as 10:02 would return 59.7). I would also like to have the interval chart stored in a .properties file, so my other "calculators" are all consistent. What would be the best way to program this?

For example: I have to generate a sound from the smartphone's speaker. The sound's length is 10 ms, and I want to generate that sound every 50 ms in an interval of 200 ms.
Definite Memory Leak. Rooted Most bloatware removed also Using ATK memory starts around 280. I have atk set hourly memory leaks to around 170 atk runs brings it back to around 200 within another hour down 100 atk runs brings it back to around 130. No push, Email check hourly. No WiFi, BT and GPS. Moderate use. Could be why some are having battery issues. This problem also exists before Rooting. Hopefully 2.2 will remedy this issue. As for rooting no real performance boost after bloatware removed.
View 8 Replies View RelatedI'm new to Android development, so I might be missing something obvious. I want to launch an activity when the user's phone clock hits a specified time (similar to an alarm). However, I'm not sure how I would go about doing this as constant polling of the clock seems inefficient and a waste of resources. Do I need to capture broadcast events from the lclock, or use PendingIntents?

View 3 Replies View RelatedI created an activity by using a layout written in a XML file. I would like, in response to some events, to change the content of this activity. I would like to show a VideoView over the content. In response to some other event, I may want to go back to the first content. Would it be possible to switch the content of the activity this way without running another activity (I have another technical difficult in doing that)? I tried using setContentView( videoView), and then switching back with setContentView(T.layout.main), but it seems that, when going back to the main layout, all my buttons and text boxes are created again as they were new. Would it be possible to go back to the last state of all the controls?

View 1 Replies View RelatedI want to display the status of the activity execution on the screen using the TextView while activity is executing. I am appending the String messages at different stages of execution in the TextView, which is defined in the Layout main.xml (e.g. TextView.append("Server started..").
For e.g. I am running socket communication application in which my android application is the server and it is receiving the messages from the local desktop. So in this application I want to show "Server started.." message when socket server on android started , then a messge "waiting for message.." and then "message receivied.." when message received by android server.All 3 steps are the part of a single activity.
But in my case, I am getting all 3 messages at a time after activity execution completed. Is there any API available, using which I can show the status during the execution also.
I want to have multiple listviews in single activity. But only one listview should be displayed at one time. The listviews will be loaded dynamically. So, how can I fill all the four listviews at the same time and display only one.
If anyone knows the solution then please share it over here. I hope to get a quick response.

View 3 Replies View RelatedDoes anyone know if there's a way to set the sync interval on accounts via sync adapter in pre-froyo? They've added the API to do so in 2.2 but I'm curious to know if there is a workaround in 2.0-2.1. (My backup plan is the alarm manager) What's odd is there doesn't even seem to be any preset interval either .so accounts are never synced!

im working on a audio profile switcher for android and as part of the entire project, i have a service that is running in the background using the following timer code:
Code:
timer.scheduleAtFixedRate( new TimerTask() { public void run() {.....}, 0, nextUpdateInterval);
What im noticing is that the timer is not honoring the dynamically generated next update interval period...the nextUpdateInterval is declared as private static long which is initialized to 30000 (30 seconds) for the first run....then once a profile is found, i do some math and update the nextUpdateInterval...i have converted the nextUpdateInterval value back out to hours/minutes for debugging purpose, and the calculation is working as expected...like it shows me in hours and minutes, when the next timer execution should take place...
nextUpdateInterval calculation:
Code:
long entirePeriodDiff = toTimeMiliseconds - fromTimeMiliseconds;
then once a profile is found, i calculate the elapsedTime like so:
Code:
long elapsedTime = rightNowDate.getTime() - fromDate.getTime();
and then i update the nextUpdateInterval:
Code:
nextUpdateInterval = entirePeriodDiff - elapsedTime;
One example scenario: Profile of 'Work' is set from 9AM to 4:30PM, the service/app is executed at 2:02PM (EST), my toast message is executing constantly (indicating the 'run' method in the timer is being executed) and is acting as a count down telling me how much time is left...in this case 2:28 and decreasing...ideally this should not display until the 2:28 is up...
