[android-developers] I want to know why my app was rejected from the Google Play./Google Playからリジェクトされる具体的な原因が知りたい。

2015-12-23 Thread 田中誠一

Hi,
My app has been removed from the Google Play.
That app is a free app that displays the ad.
I was told the reason for the rejection, but I have no idea.

The reason for rejection is as follows.
"Dangerous Products: We don't allow content that harms, interferes with the 
operation of, or accesses in an unauthorized manner, networks, servers, 
application programming interfaces (APIs), or other infrastructure.
Malicious scripts and password phishing scams are also prohibited on Google 
Play, as are apps that cause users to unknowingly download or install apps 
from sources outside of Google Play."

Is there something the possible causes when they are rejected for this 
reason?
Please give me some advice.

こんにちは。
私は先日Google Playにリリースしたアプリが削除されました。
削除されたアプリは広告収益モデルのゲームアプリになります。

削除理由を見ても、違反に思い当たる節がなく困っています。

削除理由は
停止の理由: コンテンツ ポリシーの危険なプロダクト条項への違反。
Google Play 以外の不明なソースからアプリをダウンロードまたはインストールするよう誘導するアプリは禁止されています。
です。
https://play.google.com/about/developer-content-policy.html#dangerous

「Google Play 以外の不明なソースからアプリをダウンロードまたはインストールするよう誘導する」
といった機能は当アプリに含んでおりません。

そこで質問なのですが、コンテンツポリシーの危険なプロダクト条項への違反とされるような原因で具体的にどのようなことが考えられるのでしょうか。
どうかアドバイスをお願いいたします。

[android-developers] Audio recording problem - fake sample rate

2015-12-23 Thread Robert Scott

There is an audio recording problem with some devices, even newer ones.
The native audio recording sample rate appears to be a puny 8000 Hz, which
means it can only render frequencies up to 4000 Hz. This is a problem for
my piano tuning app which must detect frequencies above 4000 Hz. to tune
the top few notes.

So far I have only gotten reports of this problem on certain models of the
LG G3 and the Nexus 7 (Asus). The worst part is these devices do not
return an error when we try to set up an audio input stream and request a
sample rate of 22050 Hz. Instead they take their 8000 samples per second
and up-sample by duplicating each sample 2 or 3 times to give us audio that
appears to be sampled at 22050 samples per second as requested, but it
still cannot faithfully render frequencies above 4000 Hz, so our piano
tuning app gives very strange results for the top few notes on the piano.

Does anyone here work with audio input apps and can you confirm this
problem on any other devices? You can test it out by sideloading our app
from

www.tunelab-world.com/atl.html

It will run in free-trial mode well enough to test this out. To test for
the sampling rate problem, tap on the large "A4" and select the note "B7"
by tapping on the "7" first. Then on a different device or computer,
generate a tone at 3950 Hz. One such on-line source is

onlinetonegenerator.com/

If this tone produces just one peak in the spectrum display at 3950 Hz,
then everything is fine. But if this produces two peaks - one at 3950 and
the other at 4050, then you have a device that is sampling at 8000 Hz and
then up-sampling to feed our app a fake 22050 samples per second.

[android-developers] Re: Audio recording problem - fake sample rate

2015-12-23 Thread Robert Scott

I first call *AudioRecord.getMinBufferSize(22050...*  If this returns an 
error (<1) then I call *AudioRecord.getMinBufferSize(44100...*  Whichever 
one of these calls succeeds, I use that rate in my call to "*new 
AudioRecord(..,sampleRate..)*"

I don't actually have one of these misbehaving devices, so my experiments 
so far have been with the help of my customers.

Unfortunately,  my guess was wrong.  I changed  the subdir from the custom 
name for my app to "Camera".  It stored the video in that folder, along 
with the pictures and videos from the stock app, but the videos from my 
custom app are still not visible in the Photos or Gallery app.

I've tried both the "sendBroadcast" and more verbose 
"MediaScannerConnection.scanFile()" approach.  Neither of these fail, and 
the latter does call the "onScanCompleted" callback, but neither of these 
seem to do anything.

Any ideas?

 Hi,

 If your phone is not a Google Nexus variety then that's not surprising,

 In some respects it does not really matter which folder you use to

[android-developers] Using Leanback Support Lib v17 on KitKat v19

2015-12-23 Thread Andy Gale



I'm trying to get the Android TV look and feel on a KitKat device by 
utilizing the Leanback Support Library. In testing the "Videos by Google" 
Leanback Support Library Sample, I've run into an issue where the card grid 
is not displaying properly, as seen here:

















To get it to build successfully with min API 19, I removed the code for 
Recommendations, background image updating with the newly focused video, 
and a few other methods which aren't available in API 19 (newer versions of 
getColor() and getDrawable()).

This stripped-down version runs fine on my Lollipop and Marshmallow 
emulators, but on KitKat emulators and a physical device running AOSP 
KitKat (4.4.2_r2), the issue above is present. 

Does anyone out there have any idea as to why this is happening and/or 
could point me in the right direction?

Re: [android-developers] Audio recording problem - fake sample rate

2015-12-23 Thread Massimo Messore

I've been working with android audio recording for a while.

As far as I know the only guaranteed supported recording sample rate is
44100Hz which means up to 22KHz of bandwidth.

This should be a "real" sampling rate, no upsampling on most devices.

Did you try to set AudioRecord with 44.100Hz as sampling rate?

[android-developers] setResponseHeaders method causes app to crash on certain devices

2015-12-23 Thread devBV

hi,
I'm using shouldInterceptRequest method to intercept the request , edit it 
and send the right response. 
It works on a couple phones I tested, but when I try to run the same code 
on a different Android device - it crashes.

the code is looks like this:

@Override
public WebResourceResponse shouldInterceptRequest( WebView view, String url 
)
{
if( (url.indexOf("Action=DoSomething")>-1 ) ){
 String str = "Success";
 WebResourceResponse response  = new WebResourceResponse( "text/html", 
"charset=UTF-8", new ByteArrayInputStream( 
str.getBytes(StandardCharsets.UTF_8 )) );
 
 HashMap headersMap = new HashMap();
 headersMap.put( "Access-Control-Allow-Headers", "Content-Type" );
 headersMap.put( "Access-Control-Allow-Methods", "GET,POST" );
 headersMap.put( "Access-Control-Allow-Origin", "http:// " 
);
 headersMap.put( "Cache-Control", "private, max-age=0" );
 response.setResponseHeaders( headersMap ); 
 
 return response;
}
else{
 return null;
}
}

I've found that without the the setResponseHeaders the app doesn't crash. 
Otherwise it runs good on phones , but crashes on a certain Android device 
that I want to run this code on.

[android-developers] how is google ADID calculated

2015-12-23 Thread doron zukerman

hey all,
im new to this group and dont know if this is the right place to post this 
but by any chance is there someone here who knows how exactly the google 
ADID is calculated?

what i mean in "calculated" is basically to better understand to what 
identity if the adid connected to? (android Os, device id, google account, 
or anything else...) and how is it reset?

the reason i  want to know this is to better understand when several does 
devices are used by the same user.

thanks in advance!

But if I change the library back to 23.0.1, this issue cannot be reproduced.

The code is very simple:

public class RcuListActivity extends Activity{

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

GuidedStepFragment.add(getFragmentManager(), new SettingtFragment());
}

public static class SettingtFragment extends GuidedStepFragment {

@NonNull
@Override
public GuidanceStylist.Guidance onCreateGuidance(Bundle 
savedInstanceState) {
String title = "RCU List";
String desc = "List of connected RCUs";
Drawable icon = getActivity().getDrawable(R.drawable.ic_launcher);
return new GuidanceStylist.Guidance(title, desc, "", icon);
}
}
}
