Android : Way To Determine Programmatically / Install Time For Droid App?
Jun 27, 2010
Is there any way to determine programmatically the time at which an Android application was installed? I don't see anything in PackageInfo, etc.
--EDIT--
To clarify, App A is installed at Time X. At some later time, Time Y, App B is installed. Is there any way App B can know when App A was installed? The link http://stackoverflow.com/questions/2831333/how-to-get-app-install-time-from-android/2920310#2920310 indicates that reading the modify time on the source dir of the App is sufficient. Is this really correct? Why?

By any means, programmatically can I get the install date & time of the already installed apps on the android device. The ApplicationInfo doesn't provide this info. While digging through the /data folder through the DDMS perspective, I saw the installed apk's do contains the Date & time of when it was installed, but the sad part is that this /data folder is not accessible on the device programmatically.

I'm trying to programmatically determine what audio applications are installed on an Android phone. I'm able to enumerate all the installed applications, but don't yet see a way to figure out which ones are capable of playing audio? What property of the application would have to queried to determine if is capable of playing audio?

I have an application that's offered in and outside of the MarketPlace.Is there a way of determining from within the code where the application came from? I've got a few indirect methods
1) I could simply infer from whether they have "Allow installation of non-Market applications" ticked.
2) Or I could just make separate builds and make it explicit in the code.

How can I determine if the current time is between two other time objects?
For example: current: 15:23, startTime: 22:00, endTime: 06:00. So the current time is not between this two other times, but this "23:47" is.
*I don't care about the date, only the time
I tried to do it like this:
Code:
Time startTime = getStartTime();
Time endTime = getEndTime();
Calendar c = Calendar.getInstance();
Time now = new Time(c.getTimeInMillis());
[Code]...
but it dosen't work well. their aren't any errors but it just dosen't work.
To be more precise the problem is that 15:35.after(22:00) return true... and I don't know why. I think that the problem is something with the dates but I don't know what

I was hoping to write a service on Android that would list all applications installed as per previous post.Then, It would decide to update automatically some apps and install others. Is there any class on the SDK that has this kind of functionality? That is, can I call some API or code to install an application on the phone? Can I force some updates as well?

Let's say I have 2 files on Desktop: (Note that I have another file than .apk application.)
.apk file
.zip file (wich contains a large of data that .apk must unizp and do some work with it).
I want to plug an Android device and programmatically copy these both files to Android.
The application must be visible to user and the .zip file must be "visible" to the application, wich will unzip it and do some work with it.
With PalmOS, I use HotSync API. With WinMobile I use ActiveSync (rapi) API. How to do it on Android?

I am new to the whole rotting thing, I installed the bugless beast on my droid 2 days ago and everything went great and it worked fine, I'm just having an issue with it being really lagy at times and the biggest problem is that it freezes everytime I open or close the keyoard, I have to forse close and wait for it to load everything up again, a message is desplayed and it says:
The application launcher+(process android.process.acore) has stopped unexpectedly. Please try again. Then I hit forse close, it usually only happens when I open or close the keyboard but sometime it will happen at random. Does anyone know why this is happening and how to fix it.

I have made a little application pushed in /system/app with adb qui connect to a server and sometime download apk for updating/installing apk on the device.
My application is a kind of "updater". I alreay can : install new apk
But I can't update an apk which is already installed in /system/app/
I don't know why, but the update is in /data/app/my-update-1.apk
The application use the new version but, if i reboot the device (a Tao3530 tsunami board), the apk in /data/app/ is deleted and the old /system/app/original.apk version used.
How could i update an /system/app apk ? (without using ADb of course). If i need to use SU command (to push from download folder to /system/app, how could i root the board ?*

I'm writing an application and would like to have some files extracted from the .apk during _installation_ time, as the files can be quite large and extracting them from the .apk during the first run results in a noticeable slowdown which I would prefer to avoid.
After lots of experimentation, I have found one way to make this work, but I'm unsure about the "long-term" ramifications of this approach, specifically: will this actually work in android-9 and later?
The approach is to name the files I want extracted at installation time as "lib*.so", and place them into the appropriate lib/ABI folder within the apk file, e.g. the .apk contains:
lib/armeabi/libMyLargeFile.dat.so and at installation time this is (nicely) installed as:
$APPDIR/lib/libMyLargeFile.dat.so
My concern is that 'libMyLargeFile.dat.so' is NOT an ELF shared library. This approach only works because PackageManagerService only checks for files matching the `lib/ABI/lib*.so` pattern (which is followed) and does not check the contents of the extracted file.
This approach works for Android 1.6 through Android 2.2. I'm wondering if this will continue to work in the future, or if I need to investigate an alternate mechanism.

Does anyone know if there is a way to identify (in code, not LogCat) when the GC has run? Perhaps an intent is fired? I could analyze the LogCat output, but it would be ideal if I could determine when the GC has run from my code.

I'm experimenting with Android's audio recording and playback. Is there a way to enumerate the available audio parameters on my device?
Right now, when I pass a combination of parameters that the hardware (or emulator) doesn't like, I just get an error. So I am having to "guess":code...
Surely there's a better way!
This chart indicates that the only supported audio input sampling rate is 8 kHz? Is that correct?

Is there a way I can find what resource a particular ImageButton is set to, at any given time?
For eg: I have an ImageButton that I set to R.drawable.btn_on onCreate. Later, at some point, the ImageButton gets set to R.drawable.btn_off. I want to be able to check what resource the ImageButton is set to in my code.

I have a layout that looks something like this:
[TextView 1] [TextView 2]
[ TextView 2 spill-over ]
Essentially, I need the contents of TextView 2 to wrap to the next line, but start where TextView 1 starts. I was thinking that if I knew how much text would fit into TextView 2 before it runs out of space on line one, I could take the rest of the text and put it in another TextView below the first two. So I need to measure how much text will fit into a TextView (which can be tricky because as far as I can tell, Android will try to break the text in a TextView at a good location so that it won't break a word in the middle if it can be avoided) or I need a new idea on how to lay this out.

I know how to get the API level, android.os.Build.VERSION.SDK_INT, but there are also several revisions of each level release, e.g. for 2.1 there's rev 1 and 2. How do I determine the revision of a build?
The reason i'd like to know this is that I have a workaround for a bug in Android 2.1 (and 2.2), and this workaround will break the moment the corresponding bug is fixed. So right now i'm in the odd position of hoping that the bug won't be fixed (at least not until I can find an answer to above question).

How does Android determine whether to move the layout up when showing the softkeyboard?
Note: I am aware that the activity property android:windowSoftInputMode="adjustResize|adjustResize|adjustUnspecified"
exists, as described here http://developer.android.com/guide/topics/manifest/activity-element.html#wsoft
, but in my case it doesn't seem to have any effect. This is my problem:
I have two activities, pretty much the same layout, but the first one is using a ListView that holds a list of buttons. The second activity holds a scrollview with buttons.
The rest is the same, same number of buttons, same height of elements, etc.
Now, when I press the search button to open the search input bar, in my first activity, the entire layouts gets moved up.
While on the second activity, the layout is not being moved up but the softkeyboard just displays on top of it. This is actually how I want it to behave. How can I achieve the same with my activity that's using the ListView?
In my manifest, initially I didn't specify any android:windowSoftInputMode attribute, but even if I do, it doesn't make any difference; I tried all three values (adjustPan, adjustResize, adjustUndefined, without any difference).
This is my layout:
1) http://pastebin.com/5zzVxjbK
2) http://pastebin.com/KFtPuHvP
Interestingly though: when I set my ListView visibility in my layout 1 (left) to View.INVISIBLE, then the layout doesn not get moved up!
