Re: [android-developers] newbie needs help - play a sound when app opens

[chicago chuck]

Thanks for the reply Steve.

I have the following in my MainActivity.java:

MediaPlayer mediaPlayer = MediaPlayer.create(context, R.raw.mysound);
mediaPlayer.start();

But Studio doesn't like context for some reason (cannot resolve symbol).  I do 
have 
import android.media.MediaPlayer;

[android-developers] newbie needs help - play a sound when app opens

[chicago chuck]

Hello,

I'm a newbie with Android Studio.

I've created a very basic app with various TextViews and ImageViews. I want 
to take the next step and have my app play a sound when it opens.

I've googled around and found a lot of info about playing a sound when a 
button is clicked, but I didn't want to start getting into buttons yet. I 
just want it to play my mp3 when it first opens.

I figured out how to create the raw folder and paste my mp3 file into it.

Is there a way to play a sound when my app first opens?

Note that this is my first attempt at doing anything with 
MainActivity.java, so if you have a code example, please let me know where 
it goes.

thanks!

[android-developers] Undocumented screen tags needed in Android Manifest to ensure app does not get filtered by default on Google Play Store for LG G3 (Clash of Clans affected too)?!

[Chuck Moyes]

I have a user with an LG G3 running Android 5 Lollipop whose Google Play 
store claims that my app is not compatible with his device, and so he 
cannot download the app from the Google Play Store.

As you can see here, the LG G3 family of devices are and were all 
compatible with my APK:



I did some digging, apparently LG G3 users are also having 
compatibility/filtering issues with Clash of Clans.

It turns out (and I kid you not) the device has an unorthodox screen 
resolution and undocumented screen density "640" that ostensibly is causing 
it to get filtered even though the Google Play Store UI has it listed as 
compatible:
http://stackoverflow.com/questions/25221643/app-not-visible-on-google-play-for-qhd-lg-g3

It's not in the documented list, and it's "blacklisted by default":
http://developer.android.com/guide/practices/screens_support.html

>From the aforementioned SO post, you have to manually add the screen 
density to the AndroidManifest using the compatible-screens tag 
(previously, my "vanilla" AndroidManifest did not have supports-screens 
tags and it also did not have compatible-screens tags).

What IS this crap?!

So I came up with what should be the most "permissive" screen resolution 
configuration possible (because my app is a 3D game that is actually 
resolution-independent, and so it should be able to run on any 
size/density/resolution screen):






















































I did this, going against Google's recommendation (I actually agree with 
Google's recommendation) because I really need my app to run on LG G3 
devices:

*Caution:* Normally, *you should not use this manifest element*. Using this 
> element can dramatically reduce the potential user base for your 
> application, by not allowing users to install your application if they have

> with specific screen configurations. Instead of using this element, you 
> should follow the guide to Supporting Multiple Screens 
>  to

>

However, when I upload the new APK to the Google Play Store, I now see that 
some (by some, I mean hundreds) devices are getting filtered (with no 
specified DPI):



I even tried adding screen tags for each screenSize without any 
screenDensity (e.g. ) to 
compatible-screens, despite my Android Studio IDE complaining that these 
tags needed to have screenDensity, but it did not work.

How can I distribute my app to LG G3 users using Google Play Store -- 
without filtering _other_ devices without specific screen densities?

In my opinion, there should not be undocumented screenDensity tags that are 
required -- and a permissive configuration shouldn't blacklist devices by 
default -- in other words, I should be able to distribute my app with a 
vanilla manifest that does not contain any special screen-related tags, and 
my app should run on all screen resolutions/sizes by default. Moreover, 
when Google Play Store says a device is compatible in the UI, it should not 
get filtered. These behaviors are creating real headaches for developers 
like Clash of Clans and myself.

Re: [android-developers] How Are Content Providers To Interpret Section 5.3 of Google Play Developer Distribution Agreement?

[Chuck Crisler]

The section sounds like they want to provide support to their current/your
former customers. I doubt that Google would sell copies of your app without
compensating you. They have too much to lose. However, for an authoritative
legal opinion you need to hire an attorney to contact the Google legal
department.

One obvious reason to buy your own app is simply to checkout the entire

insure that it goes smoothly. That is a normal part of SQA.

Re: [android-developers] thanks to all

[Chuck Crisler]

Start by reading the online Google documentation. Read/build/execute the
samples. Work to understand how they work. If you already know how to
program, it isn't hard. When you have a specific problem, after trying to
solve it yourself and looking here and in Stack Overflow, post a specific
question. Good luck.

Re: [android-developers] Access to Music Player App Source Code possible?

[Chuck Crisler]

GStreamer is another option. It is an open source framework that is used to
construct pipelines that do things, like read audio files, decode them and
play the result. You could construct your transform as a GStreamer element
that receives buffers of audio data, transforms it and then passes the
buffers onto a sink, either to save (file), transmit to another system
(udp) or render locally over speakers.

http://gstreamer.freedesktop.org/

There is a lot of documentation, examples and support forums. Yes, it also
runs on Android.

Re: [android-developers] Is anyway to make apps support 'app streaming' right now?

[Chuck Crisler]

I haven't looked at your link and I am not sure exactly what you mean by
'app streaming', but you should look at GStreamer. It is an open source
media framework that works on many platforms, including Android.

[android-developers] gesture driver

[Chuck Han]

Is there a way to create gesture drivers for the Android environment. 
 For example, I want to implement a new gesture that all apps can use.

Thanks in advance, Chuck

[android-developers] Re: How to handle dismiss of DialogFragment (support lib) while app is in background

[Chuck Krutsinger]

I already have a solid way to handle if the activity is stopped.  What I'm 
struggling with is how to handle if the activity is paused due to being in 
the background.  If the Activity is paused, then calling Android 
Compatibility Package's (ACP) DialogFragment.dismiss() triggers an 
InvalidStateException.  In that same paused state, if I call 
Activity.dismissDialog(int), the framework correctly handles the dismissal 
without causing an exception.  If I were using true DialogFragments (not 
from the ACP), I could use dismissAllowingStateLoss() and I believe it 
would be fine.  However, since I'm using ACP, there is no 
dismissAllowingStateLoss().  There is more detail on the Stack Exchange 
post for this issue, which remains open:  stack 
exchangehttp://stackoverflow.com/questions/10760809/how-can-you-handle-dismissing-a-dialogfragment-compatibility-lib-upon-completi/10761170#10761170

[android-developers] How to handle dismiss of DialogFragment (support lib) while app is in background

[Chuck Krutsinger]

I have an AsyncTask that may need to dismiss a FragmentDialog upon 
successful completion.  In a regular Activity, the dismissDialog() method 
correctly handled removing a dialog even if the app was in the background. 
 However, using a FragmentActivity and a FragmentDialog, there is no 
equivalent approach that I can find.  The compatibility library does not 
have dismissAllowingStateLoss() like the real DialogFragment class does. 
 If someFragmentDialog.dismiss() is called while the app is in the 
background, I get a crash with an IllegalStateException.

What is the correct way to dismiss a FragmentDialog upon completion of an 
AsyncTask so that I don't get this exception?

[android-developers] How can I use a junit.extensions.TestSetup in an android junit test so I can have a one-time setup and teardown fixture for the entire TestCase?

Since android.jar does not include junit.extensions package, how can I
create a fixture that only runs setup and teardown once per TestCase,
similar to how @BeforeClass and @AfterClass works in junit 4?  As you
know, android supports junit 3.8.2, not junit 4.x.  On StackOverflow
I've described my attempts to accomplish this and the issues I've
encountered (see

[android-developers] Re: No validating SAX parser for android?

[Chuck Krutsinger]

Here is the code for Android's SAXParserFactoryImpl.java:


@Override
public SAXParser newSAXParser() throws
ParserConfigurationException {
if (isValidating()) {
throw new ParserConfigurationException(
No validating SAXParser implementation
available);
}

try {
return new SAXParserImpl(features);
} catch (Exception ex) {
throw new ParserConfigurationException(ex.toString());
}
}

The Android DOM parser DocumentBuilderFactory has something very
similar.  Neither supports validation.  You have to find a 3rd party
parser of you want to validate.

[android-developers] Re: Java.lang.ArrayIndexOutOfBoundsException

[Chuck Krutsinger]

I think the problem may be with this line:

                 java.text.DateFormat dateFormat
 =android.text.format.DateFormat.getDateFormat(context);

This will get the format according to the current locale, which may
not be mm/dd/ and from what I see here doesn't even seem to
contain any '/' characters.  That is why you are getting an array
length of 1 from the .split(/) call.

Here is the warning from Android web site on this exact issue:
http://developer.android.com/reference/java/util/Locale.html#default_locale

Instead, construct the date format you were expecting to parse using
SimpleDateFormat.  For example:

java.text.DateFormat dateFormat = new
SimpleDateFormat(MM/dd/);

This should work better if you force the format to be what you were
expecting to parse.

[android-developers] Re: OnKeyListener is not working, why?

[Chuck Krutsinger]

Are you trying to capture the back key which normally would act like
cancel?   Or are you trying to capture the backspace key, which
deletes the previous character?  If it is the latter, you should use
KeyEvent.KEYCODE_DEL.  If it is the former, you might try changing
your code as follows to get more diagnostic info:

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
 Bundle savedInstanceState) {

          View myView = inflater.inflate(R.layout.note, null);

         myView.setOnKeyListener(
                 new OnKeyListener(){
                         @Override
                         public boolean onKey( View v, int keyCode, KeyEvent 
 event ){
 Log.V(keyCode= + keyCode);
                                         if( keyCode == KeyEvent.KEYCODE_BACK 
 ){
                                                 Log.v(CALL ME, I am 
 called);
                                                 return true;
                                          }
                                         return false;
                          }
         });

       return myView;

 }


This will confirm whether or not your onKey() is even being called and
what keyCode value is being received.

[android-developers] Re: Android compatibility clarification

[Chuck Krutsinger]

If you want your program to run on your phone, you will have to stick
to the 2.2 version of Android.  If you want to develop to later
versions, you can, but you will have to use an emulator to run and
test the application and you won't be able to deploy to your phone
until you upgrade to those versions.  If you write to the 2.2 version,
it should still run on the later releases, but not the other way
around.

[android-developers] WebView and Response Processing

[Chuck Kasek]

Currently, I use a regular activity with some EditText fields as a
registration screen in my application.  The inputs are used to
construct a soap message which is posted to the registration server,
with the response being parsed to do some configuration of the
application.

I'd like to change this to have the registration page load in a
WebView instance, so that the registration process takes place on an
external web page.  This would make it easier to make changes to the
registration process without having to deploy a new build, as it would
just be a matter of changing the web page that is loaded in the
WebView.

The question is - would there be any way for me to get the response
that is sent back from my registration server to the client?  From
what I can tell, if I went this route, there wouldn't be a way for me
to parse the response like I currently do to initialize the
application settings.  Any help is appreciated!

 If you are loading resources, you should strongly consider making this a

 If your singleton is doing things you know are global to the app -- for

 configuration, and loading shared preferences under an explicit name -- then
 truly making it a singleton is fine.  Just have the call to get the
 singleton take a Context, and when called the first time and constructing
 the singleton use getApplicationContext() on that to keep the context you
 will be holding in your singleton.  This is essentially the context for your
 package, which is also your class loader, which you are singleton of.  There
 is nothing funky or wrong with putting things together like that.

 So doing a singleton this way is in my mind the simplest, and as long as you

 nothing incorrect or not robust about it.

[android-developers] Re: Singleton object with context?

[Chuck Lega]

Thanks for great input!
I guess the Application object may be a simple way to store some
common data, but when implementing an Util/Mgr-like class with state
and context I think a separate class is to prefer.
Passing context with each call may be clean, but does not cover all
cases. For instance, say I register a listener in the singleton. The
callbacks to the listener does not contain a context, and I am back at
square one again...

So, I guess init-ing the singleton with a context is the simplest way,
and making it a service the most robust/correct(?).

 The Context you have from extending Application is the same context you get
 with Context.getApplicationContext().  I generally recommend that people use
 singletons instead of extending Application, and the semantics of Context
 here isn't different between the two

[android-developers] Re: Singleton object with context?

[Chuck Lega]

Ok, I may be a bit vague, but say I want an utility class to do some
common stuff, including resources and shared prefs. Then I need a
context. If I put a SharedPreferenceListener into the class, I am lost
if I want to do something using a context when receiving the
callbacks.

This is how I think about it now: singleton object with init(ctx).
Init is called from App, i.e. with appctx.
What would typically this (app)context not be suitable for?

Sorry for deviating...

 What listeners and callbacks are we talking about? You may want to provide
 more, um, context (har har) about how you're using a singleton, callbacks,
 listeners, and the Context. There's probably a better way than initializing
 the singleton with the Context object.

 And making your singleton a Service may not necessarily be the most robust
 /correct - it depends on what you're trying to achieve with this singleton.

[android-developers] Singleton object with context?

[Chuck Lega]

Hi,

I often run into the following dilemma: I need some singleton-like
object in my app (typically some central manager-like thing) and this
object needs a context for various things. This means that I either
have to pass a context to all methods needing one or have some sort of
init-pattern to the object. Neither is pretty I think. What is the
correct way of doing this? Or is this simply (even the definition of)
a Service?

Anyone have any thoughts on this?

Re: [android-developers] Avoiding GPL

[Chuck Tilbury]

 As I understand it (and I disclaim any responsibility for your 
actions, whatsoever) is that if your thing adds to a GPL'ed thing, 
then you have to GPL your work as well.  However, if your thingy simply 
uses something that is GPL'ed, then your do not have to place your work 
under the GPL.  The basic intent of GPL is to make sure that the 
software remains available as source code to anyone that wants it.  A 
good example of this is the standard C++ libraries for the GNU compiler 
set.  There is also the LGPL, that allows you to add to the software 
that is under that license without open-sourcing it.  If you use a 
GPL'ed software to create your own (separate) software, then you have to 
supply at least a pointer to the GPL'ed source code.  You do not have to 
supply your own source code if it is not GPL'ed.  Take a look at how 
they do it on transgaming.com.


I think that many corporations buy licenses for open sourced software 
for a number of reasons that do not involve open-sourcing their 
applications.  For example, if a corporation creates an application and 
then only uses it internally, it does not have to be open sourced AT 
ALL.  PERIOD.  To open source or not to open source is only a question 
for situations where you plan to make money by selling the actual 
software.  Corporations buy support and development services from 
companies such as MySQL.


Assuming your software is released under the GPL: The GPL license does 
not deprive you of ownership of your software.  There are many instances 
of people changing the license that they release software under.  GPL 
does not deprive you of the ability to sell your software.  It only 
stipulates that you cannot deprive anyone who asks for the source code.

Chuck T.

 See Red Hat for an example of how that works..)

But I was referring to MySQL, not the connector. Also, sure there will
be also corporates who pay for not using the GPL, but my point was
that one is not forced to pay to use it. Now I think we are made clear
our points, and MySQL was only an example.

 And; the INTENT of MySQL is that if you use the GPL version of the
 MySQL database, your application should also be GPL. But, of
 course, there are loopholes. However, using these loopholes in a
 way that is obviously a circumvention is against this INTENT.

 If you want people to respect YOUR intellectual property, you
 should respect others as well, and not exploit their software in an
 unintended manner.

Licenses arbitrate how much land each entity has the right to own, in
other words they establish borders in a objective way that everybody
agrees on, not a subjective or moralistic one. So while I personally
might have some interest in what other people are willing to do
(subjective and moral position), not everybody is compelled to do
that, but only respect the law. Everybody uses licenses to try to
place that border in the most convenient possible way. An author of
FLOSS software tries to place the border in the best possible position
in his perspective, and a user of a FLOSS software has the same right,
in his perspective.

PS MySQL intent was to make money, and GPL is one of the best way to
do that, because of the double licensing thing. In fact, they made a
lot of money. Note that the owner of MySQL has changed many times and
the intents of the original founders, of Sun Microsystems and Oracle
might have been changed. Frankly, if I used MySQL I wouldn't be
interested in what their intents are, only in what I can do.

[android-developers] Disabling intent-filter in runtime

[Chuck Lega]

Hi,

Is it possible to disable or even remove an intent filter for an
activity in runtime when the filter initially was set in the manifest?
Example:
activity
android:name=com.bla.bla
...
intent-filter
action android:name=android.intent.action.SEND /
category
android:name=android.intent.category.DEFAULT /
data android:mimeType=image/* /
/intent-filter
 /activity

...and then sometimes don't want my app to turn up in list of apps
being able to send images.

Possible? Permanently remove?
I was thinking PacketManager, but cannot find anything suitable there.

[android-developers] Disable intent filters

[Chuck Lega]

Hi,

Is there a way to turn off or remove an intent filter of an activity
that is set in the manifest? This would typically be usable if the app/
activity for some reason don't want to show up in the CHOOSER list for
say images/SEND.

[android-developers] Vietnamese language?

[Chuck]

Just a quick query and suggestion from a NON-DEVELOPER -- but a
consumer, sorry for the non-technical intrusion.

I HOPE someone is developing some language flexibility with the new
phone.  I finally ditched my Palm Treo 650 and ONLY because it offered
no way to adapt Vietnamese language tones, and switched to a Nokia E71
mainly because it DOES allow me to use the Vietnamese language tone
marks -- sometimes critical to accurate spellings and meanings, even
for a foreigner like me, not particularly literate in Vietnamese.  But
sometimes that option for accuracy is important.

I hope developers are thinking about that feature, which likely
applies for other languages as well, with words that are dependent on
an acute or grave accent, a cedilla or tilde or other diacritical
marks.

Thanks.
