[android-developers] How do I enable the phone's key guard programmatically?
Hi! How do I enable the phone's key guard programmatically? The use case is that I want to make an app that enables the key guard when I use my Bluetooth headset to answer a call. Currently with my HTC Hero there's no way for me to physically enable the key guard during a call since the phone's lock button doubles as a hang-up button during calls. And if I answer a call with my phone in my pocket the phone tends to hang up on me after a while... PowerManager.goToSleep() looks promising, but apparently I'm not allowed to call that without the DEVICE_POWER permission which I can't have. And even if I could call it, would it do the right thing during a call? KeyLockManager only seems useful for people who want to *prevent* the lock screen from appearing, but I want to trigger it.

This might be a bit crude, but what I usually do is this: 1. Search Google for: mediarecorder.java site:.kernel.org 2. Click on the first hit. 3. Find MediaRecorder.java on that page and click on the "blob" link next to it. 4. Click on HEAD. I've always found the source code I wanted this way. YMMV.

To answer my own question in case somebody else wants to know, what people do is simply to change the description of the app after every release, so that it includes a description of the latest change.

The wiki page says it's a radius if I interpret it correctly: " In order to apply the CEP concept in these conditions, we can define CEP as the [...] radius of a circle within which 50% of rounds will land.

If I do Location.getAccuracy() I get a number of meters. Is that number a radius or a diameter? I thought it would be a radius, but Google's MyLocationOverlay uses that value as a diameter.

[android-developers] Geocoder.getFromLocationName() has bad javadocs
There is a Geocoder.getFromLocationName(name, max, lat, lon, lat, lon) method. The documentation says it should search inside the (lat, lon, lat, lon) bounding box: http://developer.android.com/reference/android/location/Geocoder.html#getFromLocationName(java.lang.String, int, double, double, double, double) In reality I get lots of hits outside of that box and none inside it when I use that method.

[android-developers] Geocoder.getFromLocationName() vs bounding box?
Hi!
I'm trying to use Geocoder.getFromLocationName() with a bounding box,
but:
* On 1.5 I get lots of results outside of my box.
* On 1.6 I get no results at all.
How should I use Geocoder.getFromLocationName() with a bounding box so
that I get results inside of the box but not outside of it?
Here's what I'm trying to do. The example address "Storgatan 5" is
very common in Sweden and exists in lots of cities, so it's a good
test case. The bounding box covers the Stockholm area:
/**
* Try to find Storgatan 5 in Stockholm using {...@link
Geocoder#getFromLocationName(String, int, double, double, double,
double)}.
*
* On 1.5, this example finds tons of "Storgatan 5"s, none of them
inside the
* box unfortunately.
*
* On 1.6 I get no results at all from this code.
*

Solution is to run all tests on the simulator (or the real device).
Visually it still looks the same in Eclipse, thank you Eclipse ADT

Is this documented anywhere? I looked here...

[android-developers] Re: How do I know whether my device is currently charging?
Thanks Mark, that was the hint I needed.
What I really wanted to know was whether or not the battery was
currently in use, and for anybody else following this thread, here's
the method I came up with:
"
/**
* Is the battery currently discharging?
*
* @return True if our battery is discharging. False otherwise.
*/
private boolean isDischarging() {
// Contact the battery manager
Intent batteryIntent =
registerReceiver(null, new IntentFilter
(Intent.ACTION_BATTERY_CHANGED));
if (batteryIntent == null) {
Log.w(DrainOMeter.LOGGING_TAG,
"Failed to talk to the battery manager, assuming
we're on battery power");
return true;
}
// Ask about battery charging status
int batteryStatus = BatteryManager.BATTERY_STATUS_UNKNOWN;
if (batteryIntent != null) {
batteryStatus =
batteryIntent.getIntExtra("status",
BatteryManager.BATTERY_STATUS_UNKNOWN);
}
if (batteryStatus == BatteryManager.BATTERY_STATUS_UNKNOWN) {
Log.w(DrainOMeter.LOGGING_TAG,
"Failed to get battery charging status, assuming
we're on battery power");
return true;
}
return batteryStatus ==
BatteryManager.BATTERY_STATUS_DISCHARGING;
}
"

[android-developers] How do I know whether my device is currently charging?
I want to know if my device is currently charging. How do I find that out? I've been looking a bit at the Intents API, but AFAIU I can just subscribe to events from there, and a subscription is not what I'm after. And even if I *did* want updates, I'd still need to know the initial state. I just want to ask a one-shot "are we charging" question. How can I do that?

[android-developers] Re: Probing for an already set Alarm?
I'm not a big fan of doing double bookkeeping like this, but it should be doable here if I have a Preference stored with the time at which I expect the next alarm to trigger. Then I could just unconditionally re-trigger that alarm both from the UI and from the sampler. That said, I still feel that I'm trying to duplicate the AlarmManager's bookkeeping here, and just being able to ask it about its state would feel cleaner. Thanks for all your feedback!

[android-developers] Re: Probing for an already set Alarm?
Let's say I change my code to: Pseudo code for the UI: 1. Set an updating alarm in 15s, request INITIAL. 2. Show UI based on existing data. Pseudo code for the sampler: 0. If INITIAL, and we have samples in the database, return without doing anything. 1. Take a sample and store it in a database. 2. Schedule a new alarm in 10 minutes, request KEEP_GOING. Was that what you had in mind? Then let's assume i re-start my phone, and launch the UI: 1. UI sets an alarm requesting INITIAL. 2. The sampler receives the alarm, sees that there are already samples in the database, and never initiates the sample-and-set-up-another- alarm chain. So in the above case I still don't see how I can get around not being able to check for pending alarms :-(.

It has a thread that wakes up regularly to take a snapshot of /proc:
http://bazaar.launchpad.net/~walles/drain-o-meter/trunk/annotate/head%3A/src/net/launchpad/drainometer/StatisticsCollector.java
private void doPeriodicUpdates() throws InterruptedException {
// Make two updates in quick succession to begin with to

display
// any data.
doUpdate();
if (done()) {
return;
}
Thread.sleep(15000);
doUpdate();
while (!done()) {
Thread.sleep(SAMPLING_INTERVAL_SECONDS * 1000);
doUpdate();
}
}

With the alarm implementation, starting the UI means taking one
sample.
What I really want is for the samples to be taken independently of
when the UI starts.
Pseudo code for the UI:
1. Set an updating alarm in 15s.
2. Show UI based on existing data.
Pseudo code for the sampler:
1. Take a sample and store it in a database.
2. Schedule a new alarm in 10 minutes (exact number still being
tuned).
The first time the UI code is called (when no sampling has occurred),
everything is fine. Sampling starts after 15s.
The second time the UI code is called (when we have been sampling for
a while), a new alarm is set to trigger a new sample in 15s. The
existing alarm (in 10 minutes) is thrown out implicitly by the
system. The setting of this new alarm, and the throwing out of the
existing alarm is what I want to avoid.

If I do it badly it will show up in the stats, and I even highlight
the Drain-O-Meter itself in the listing for this precise reason.
Overhead is still OK :-).

[android-developers] Re: Probing for an already set Alarm?
Good point :-), here's the plan: I'm writing an app to find out what apps are using the most CPU time (which I hope will correlate with battery drain). It's possible to get a snapshot picture of this by looking at /proc: http://bazaar.launchpad.net/~walles/drain-o-meter/trunk/annotate/head%3A/src/net/launchpad/drainometer/proc/ProcSnapshot.java A single snapshot picture will however miss apps that start, run for some time and then exit. So what I want to do is to take *regular* snapshots. I take the difference between the last two snapshots and add the difference to a process name -> number of ticks Map. Snapshotting rules are: * Snapshots should be taken at regular intervals. * The first two snapshots should be taken in quick succession to be able to quickly present the first measurement to the user. * It must be possible for an UI app to look at the result of the snapshotting. To get the whole thing going, I'm letting the UI part of the application start the sampler in the background. When the sampling is first started it needs to take two snapshots quickly (see above). The rest of the samples should be taken at longer intervals. I first tried to do this using alarms, but I didn't manage to get the "two quick samples first and the rest further apart" behavior with alarms: http://bazaar.launchpad.net/~walles/drain-o-meter/trunk/files/39 I now have a working implementation with a background service: http://bazaar.launchpad.net/~walles/drain-o-meter/trunk/files/57 Suggestions on how I should *really* be doing welcome :-).

[android-developers] Getting longer stack traces from DDMS?
I read this blog about how to use DDMS to track memory allocations. http://android-developers.blogspot.com/2009/02/track-memory-allocations.html Using those instructions, I was able to get allocation stack traces. Unfortunately the stack traces only go 8 deep (at least when running against the simulator), and that's too little for me to know where in my code the allocations really originate. How can I raise the limit from 8 to something higher? Regards //Johan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

I'll use a Service instead of an Alarm and keep it running in the
background. That way I can keep track of it myself.

[android-developers] Probing for an already set Alarm?
Hi!
How can I probe for whether a specific alarm has been set? I set the
alarm as illustrated below, but how can I ask the OS whether or not
the below code has been called? The point is not to overwrite an
existing alarm with a new one.
public static void scheduleNextUpdate(Context context, long
delay_seconds) {
Intent intent = new Intent(context, Updater.class);
PendingIntent pendingIntent =
PendingIntent.getBroadcast(context, 0, intent, 0);
AlarmManager alarmManger =
(AlarmManager)context.getSystemService
(Context.ALARM_SERVICE);
long now = System.currentTimeMillis();
long later = now + delay_seconds * 1000;
Log.d(DrainOMeter.LOGGING_TAG, "Scheduling next update in "
+ delay_seconds
+ "s at "
+ new Date(later));
alarmManger.set(AlarmManager.RTC, later, pendingIntent);
}

[android-developers] How to improve existing Android applications?
How do I get (for example) the Android Calendar app into Eclipse so I can modify it and send in patches? There's a ton of documentation on how to create *new* apps, but so far I've been unable to find any info on how to get *existing* apps into Eclipse. And my own attempts have gone so-so :-p. A good place for this information would be the developer FAQ for example: http://developer.android.com/guide/appendix/faq/commontasks.html Regards //Johan --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
