Ok, following this information and some other advice (I created a custom 
subdir of "DCIM" for my app), I ended up with the following:

sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, 
Uri.parse("file://" + outputFilePath)));


 The problem is, it's not clear to me that this is doing anything.  After 
storing one of these and calling this, I exit my app and run the Photos 
app, and the new video is not shown there.  I've verified that the video is 
stored and viewable.

 Despite the fact that this is a custom app, as much as possible I'd

 at 
 least means storing them in the same place, with a consistent naming and

 the stock camera app will store videos, along with any other configuration

 How can I get this information within my custom app?

Note that I did already say that I'd found multiple ways to do this, and I 
was looking for advice on the actual best (or at least better) way to do 
this, and you pointed me to a selection of choices, with no information on 
tradeoffs.

In any case, I tried the first one (creating an AudioTrack and then playing 
it), and wrapping it with a Runnable and a started Thread, and I heard no 
sound from my device when the code executed.

If it matters, here's the method I ended up with:

private void playTone() {
new Thread(new Runnable() {
@Override
public void run() {
int minSize = AudioTrack.getMinBufferSize(8000, 
AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT);
AudioTrack  audioTrack  = new AudioTrack(AudioManager.STREAM_MUSIC, 
8000, AudioFormat.CHANNEL_CONFIGURATION_MONO,
AudioFormat.ENCODING_PCM_16BIT, minSize, 
AudioTrack.MODE_STREAM);
audioTrack.play();
}
}).start();
}

[android-developers] Checking out and building a custom kernel for shamu (Nexus 6) ROM

[Yile Ku]

Hi,

I am currently building the aosp_shamu-userdebug ROM image.  The setup is 
working.  I now want to build a kernel.  I am following the instructions 
on: http://source.android.com/source/building-kernels.html.  I checkout the 
msm source tree using git: git clone https:
//android.googlesource.com/kernel/msm.git.  I get an empty 'msm' 
directory.  The instructions then say to:

$ git clone https://android.googlesource.com/device/ti/panda
$ cd panda
$ git log --max-count=1 kernel

If I do a 'git log --max-count=1 kernel' command in the 'msm' directory I get: 
yile@ubuntu:~/msm$ git log --max-count=1 kernel
fatal: ambiguous argument 'kernel': unknown revision or path not in the working 
tree.
Use '--' to separate paths from revisions, like this:
'git  [...] -- [...]'
yile@ubuntu:~/msm$ 

Whats up?

I am building shamu 6.0.  which kernel version should I build for this release 
of android?  Also how does one tell what version the zImage-dtb is ?

Thanks
Y-

[android-developers] Re: How to store videos with similar naming scheme as stock camera, but in custom camera app

[gjs]

Hi again,

Actually ../DCIM/Camera is the expected sub folder for the default Camera 
app, my apologies.

What I've seen on some devices is that different apps will create 
additional subfolders beneath ../DCIM for example the Google Cardboard 
Camera app creates ../DCIM/CardboardCamera

On a Non Google Nexus phone device I see -

../DCIM/100ANDRO
../DCIM/Camera
../DCIM/CardboardCamera
../DCIM/Screenshots

- so perhaps following that convention and create your own subfolder 
beneath ../DCIM that way it is still within the expected media folder 
hierarchy and importantly your media files probably won't get deleted when 
someone uninstalls your app (!)

Regards

[android-developers] Relative accelerometer reading.

[Tobiah]

Given that I can read the effects of gravity on my device on three axes, 
I'm looking for some math that will get me a more logical view of what's 
happening to the device in my hands. I want to create a two dimensional 
control based on tilting the device forward and back, and tilting the 
device to the right and left.


The seemingly complex part is that I'd like to have the controls behave 
in a predictable way regardless of the starting position that the device 
happened to be in when starting the controls. For instance, if the user 
is in bed holding the phone upside down above their head, everything 
should still work the same from the user's perspective even though the 
numbers coming off of the accelerometer will be entirely different. I 
can envision some sort of transformation that would yield numbers that 
look like the device is starting off on a flat table, given the actual 
state of the device when the controls start to be used.


Thanks for any help.

[android-developers] Re: How to store videos with similar naming scheme as stock camera, but in custom camera app

[gjs]

Hi,

If your phone is not a Google Nexus variety then that's not surprising, but 
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM) is 
what's recommended.

In some respects it does not really matter which folder you use to store 
media generated by your app (*), provided you go to the trouble of 
'cataloging' the media generated using MediaScannerConnection - 
http://developer.android.com/reference/android/media/MediaScannerConnection.html#scanFile(android.content.Context,
 
java.lang.String[], java.lang.String[], 
android.media.MediaScannerConnection.OnScanCompletedListener) then your 
photos / video will quickly show up in the default 'Photos' app, without 
having to wait for it to scan the device periodically to find new media 
files.

(*) And is some other respects it really, really does matter what folder 
you use - if you don't want the media files deleted when your app in 
uninstalled (!) Be very careful about what you decide, here's some 
'interesting' history 
- https://groups.google.com/forum/#!topic/android-platform/14VUiIgwUjY%5B1-25%5D

 Because I can't bring up the stock camera app with just a video 
 record/stop button (I'm using a remote bluetooth button to start/stop 
 recording), I've written a custom app that just displays the camera 
 preview 
 and a video record/stop button.

 Despite the fact that this is a custom app, as much as possible I'd 
 like to store the videos as if they were taken with the stock app.  This 
 at 
 least means storing them in the same place, with a consistent naming and 
 metadata scheme.  I might consider having custom preferences in the app, 
 but for now I'd just like to retrieve properties that will tell me where 
 the stock camera app will store videos, along with any other configuration 
 that should describe how I store the videos.

 How can I get this information within my custom app?

Re: [android-developers] i have problem, in android studio "Cannot resolve symbol 'SetOnClickListener' ".how to handle. thanks

Hi aang,


AdapterView does not support onClickListener. You should  use
OntemClickListener instead of onclickListener. go through this link.

And see nested class documentation.

[android-developers] SharedPreferences doesn't work for my app but other apps is ok.

[Cihan KALOĞLU]

Hi,

I tried all ways how many i know.

That is my code block for test. (MainActivity.onCreate())

String REMEMBERME_PREF_NAME = "rememberme";
SharedPreferences sharedpreferences = 
this.getSharedPreferences(REMEMBERME_PREF_NAME, Context.MODE_PRIVATE);
if (sharedpreferences.getString("email", "").equals("")) {
Log.d("SHARED PREF", "onCreate() returned: " + "CAN'T REMEMBER");
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.clear();
editor.putString("email", "REMEMBERED");
editor.commit();
}
Log.d("SHARED PREF", "onCreate() returned: " + 
sharedpreferences.getString("email", ":("));




This code working for all new apps or other existing apps but it still 
doesn't work for my app.

What is wrong with my app?

Could anybody help me?

Thank you.
