Re: [android-developers] Any suggestions for Ad platform in addition to AdMob

[Miguel Morales]

I suggest you take a look at:
https://github.com/mopub/mopub-android-sdk/wiki/Getting-Started and
https://github.com/mopub/mopub-android-sdk/wiki/Banner-Integration

I'd probably stay away from low paying networks beside the ones stated
before.  Good luck.

Re: [android-developers] Any suggestions for Ad platform in addition to AdMob

[Miguel Morales]

Nathan,

I think you may have to do less work if you use Burstly or Mopub as your
mediation platform and demote admob to a second class citizen.  The require
less SDK integrations.
You are right, the rich media ad units are the ones that will give you the
most bang per impression.  I'm not as familiar with Mopub, but i know
burstly can deliver rich media ad units from many 3rd party networks into
their SDKs.

I *believe* they built their system where it takes into account the
permissions available and delivers the appropriate ads.  At the very least
you could just have the INTERNET permission to be able to load most ad
units.
Doing s2s integrations would take some serious time and resources.  It
boils down to having your own server and support MRAIDv2 in your
application.  Mopub has open source MRAID compliant SDKs that you can drop
into your application.  This will take down bloat and give you full control
but it'll take a long time to develop.

A prepackaged solution like Burstly might be your best choice.  In which
case you could use something like Chartboost (static images, high cpm) and
supplement it with admob or something.
The highest paid networks, though, will have you install an SDK simply
because of the complexities of the ad unit.

There are a few choices and it depends on your scenario.

Re: [android-developers] Any suggestions for Ad platform in addition to AdMob

[Miguel Morales]

Oh, I forgot to mention that banners are probably one of the worst ad units.
Some of these networks have full screen interstitial that'll make you much
more money per impression.

Re: [android-developers] Any suggestions for Ad platform in addition to AdMob

[Miguel Morales]

Hi,

I work for an monetization startup so i think i can weigh in on this.
We're currently not on Android, so i think i can be fair.

The networks beside us I can recommend are:

Chartboost
AdColony
Burstly
Mopub

Most Ad SDKs give you a no fill response so you can always build your own
waterfall or go for a mediation platform.

Miguel.

I'm not sure if anyone else suggested this.  Why don't you just use a web

Re: [android-developers] Regarding Freelancing

[Miguel Morales]

The best way to find a job is to show off your creations.
Employers value developers who take the time and program application on
their own.
Link to the applications you've developed and people will notice.

You need to provide more details and possibly code and screenshots for us

Most likely when you are doing onItemSelected you are not mapping it to the

Again, screenshots would help.

Android does indeed support UDP but I've seen carriers that drop UDP

Re: [android-developers] Re: Rendering off UI thread causes ANR on Samsung Note

[Miguel Morales]

Yeah that's really weird, good luck with your issue.  You may want to start
looking into work-arounds, but what a pain.
Ugh, this just adds to the fuel of the fragmentation flames.

Looking at this page:
http://developer.android.com/guide/topics/graphics/2d-graphics.html you'll
see what you're doing is actually encouraged.

Re: [android-developers] Re: Rendering off UI thread causes ANR on Samsung Note

[Miguel Morales]

Well, try adding a sleep first and then check your results again.  You can
then rule out the CPU consumption there and then.
Otherwise, it indeed may be a bug.  Perhaps that implementation creates a
lock or something and lets the UI thread from continuing.
That is the root of the issue, that the UI thread is not able to delegate
events and maybe stuck waiting for a lock or executing code.

Re: [android-developers] Re: Rendering off UI thread causes ANR on Samsung Note

[Miguel Morales]

Also, if you have a very tight infinite loop.  The scheduler won't know
that there's a break for the processor so that it can do other things.  You
may also want to add a Thread.sleep() call.

I second the OpenGL route.  It's pretty much the only thing that'll give
you the performance you want.  You may also want to check:

Re: [android-developers] How to read the large sized text file

[Miguel Morales]

I think the problem is that you're reading the whole file into a byte
array.  This is bad.  Try using a buffered input stream.  In other words,
stream read the file.  You should also know that phones are very limited in
memory.  Loading more than a few MB into memory spells trouble.

Thanks for suggesting me, but I m actually having a large text file.
And thus it would be much difficult for me to fill database one by one a
lot of records.

Do you have any suggestion for filling my database using that text file?

Re: [android-developers] issue with conditionally choosing first activity to be displayed

[Miguel Morales]

Oh yes that's right.  You can simply have a splash screen launch activity
and have your logic there.  Or still have your own application subclass and
have your launch logic in the application onCreate.  Mostly a matter of
taste on how you do it though.

Re: [android-developers] issue with conditionally choosing first activity to be displayed

[Miguel Morales]

I haven't done this myself but I *think* you dont have to set a default
activity.
You might then be able to subclass the Application class and override
onStart() and launch an intent there.
Again, not even sure if this is possible but might be a bit cleaner.

Re: [android-developers] Re: Memory leaks when using bitmaps in android

[Miguel Morales]

Working with bitmaps is a little hard on Android.
One thing to do is to resize or pack them so that they take up less memory.
Another thing you may want to look into is to reuse the bitmap
object/memory.  You may have to do this in native though.
As other have pointed out System.gc() just gives the system a hint that it
needs to run the garbage collector.

Good luck.

Re: [android-developers] Re: Display many images into the Imageview in 3-4 seconds

[Miguel Morales]

Try the tutorial I sent.  Also, dont load the images into memory that's
your issue.
Save to memory cache, then read them from file right before you need to
draw them.

TimeTask already runs in a different thread, so seems like you're having a
memory issue.

Re: [android-developers] OT How to Automate Build Tasks in Eclipse?

[Miguel Morales]

That's probably because you suck at writing readable Perl.
Perl is as readable as any other language.  Batch is next to useless.
I also use Perl for my iOS autobuild and its libraries made the build
system a breeze.

Re: [android-developers] OT How to Automate Build Tasks in Eclipse?

Simply combine ant with a script.  I use Perl for my build scripts because
Ant can be tedious to work with.  However, use Ant as a base to compile
your projects.

Re: [android-developers] Porting Application

[Miguel Morales]

3D image galleries?  I don't think those are standard in iOS are they?
 IIRC, the iOS default gallery is very similar to the Android gallery.
If you want to make 3d gallery for Android you'll probably have to find an
opensource implementation or program your own.

Re: [android-developers] Re: splash screen

[Miguel Morales]

Well, to be honest you don't really need a splash screen.
What is taking so long is that you are loading the images in the same
thread as the UI thread.
This makes it hang while you load your bitmaps.  I'm surprised you're not
getting an application not responding alert.

What I do in my game is load bitmaps in a background thread.
Simply show a progress dialog while the background thread loads the
bitmaps.  Then tell the UI thread that all the resources are ready to go.

Something like:

void onCreate() {
Handler callbackHandler = new Handler() {
 @Override
 public void handleMessage(Message msg) {
   //all resources have been loaded...
 }
}

class MyThread extends Thread {
Handler handler;
MyThread(Handler cbHandler) {
handler = cbHandler;
}
@Override
public void run() {
//load all the images here...
handler.sendEmptyMessage();//let the UI thread know we're
done.
}
}

//show progress dialog here...
new MyThread(callbackHandler).start();
}

Re: [android-developers] Re: Suspended app

[Miguel Morales]

Haha, nothing in this world is fair.  Come on now, you just got unlucky
that you got caught.
Next time try creating something more original and stop trying to leech off
other companies.

BTW, you should really consult your lawyer.  I'm sure you consulted him/her
before uploading the app.

Unless the app is open source, you can't.

Re: [android-developers] Re: About Phone GAP

[Miguel Morales]

It's ok for what it is.
But, it's just all the layers of abstraction in HTML/JS that make it really
slow.
I doubt they will gain much more speed on mobile devices, perhaps by using
hardware acceleartion.

In either case, it's slow and it looks and feels like crap.
But it's perfect for simple apps, users just want things that work.
 Although they prefer things that work well.

Re: [android-developers] pausing games: dealing with Handler Messages timers

[Miguel Morales]

Well, having neat code is pretty useless in a game is you are going have
sync issues.
Furthermore, it's standard to have a game loop and a draw loop.

Plus, you are adding the overhead of using message queues.  Also, if you
are launching or using a thread for each sprite the game is going to slow
down significantly from all the overhead.

Re: [android-developers] pausing games: dealing with Handler Messages timers

[Miguel Morales]

Why are you using timers?  That seems needlessly complicated.
Use a game loop that keeps a constant frame rate.
Maintain state in your sprite objects, use the game loop to update this
state.
Then on a separate draw loop draw the sprite according to its state.

Then you dont have to worry about weird sync issues.

Re: [android-developers] Re: how do i know if i am on road between two points in android

[Miguel Morales]

This is really easy if you use your own server.
Simply store lat/long values for the points you'd like.
To get points near another point construct a lat/long perimeter around it.
Basically, like a rectangle you'll have a start x,y lat/long pair and an
end lat/long pair.
You can then query your database to pull points within that perimeter.

I suck at math so I used:
http://search.cpan.org/~asp/Geo-Calc-0.04/lib/Geo/Calc.pm
Some APIs may offer something like this.

FYI, as other have pointed out.  This has little to nothing to do with
Android.  Everyone has given you good tips, but come back with Android
specific questions plz.

That's not detailed at all, very bad explanation.
Again, you'll have to post code, logs, etc.

Re: [android-developers] Re: Urgent help required

[Miguel Morales]

Why not have the HTTP server on the PC and use the Android device as a
client?

You'll probably have to post code, logs, etc to get better help.  At least
explain, in much better detail, your issue.

Those aren't really built in, they're just images.  So use images in your

Re: [android-developers] Icon Sets

[Miguel Morales]

It depends on the license of the artwork I believe.
If you're going to purchase art, it's always good to retain the copyright
so that you can use it as you wish.
That's why sometimes it might be better to pay an artist for a custom set
than using licensed images.

Re: [android-developers] Re: TextView -- text transformation

Make it a custom webview and use html?
There's also spannable which lets you define things like clickable links in
text.  I believe it also supports html formatting.

Re: [android-developers] Apple plist files

[Miguel Morales]

Try looking for a simple java library that deals with plists.
It's funny because I've been researching this myself but for Perl.

Re: [android-developers] Bad performance in communication over TCP-Socket

[Miguel Morales]

That seems overly complicated, what are you trying to do?
I *think* your bottle neck is that you're reading 1 byte at a time.
You need to read more, if you simply expand your buffer your code may
work.

The way I've done is is to have a separate thread that's strictly for
TCP communication.  There is no reason to have delays in your code
unless you're trying to throttle it, and even then it's just better to
do it inside a read loop in a separate thread.
So, after reading some bytes in this thread, I simply send these using
a Handler/Message object.
However, at this points the bytes are indeed copied if I'm correct.
If you want to avoid that overhead, you can just use a lock around
your data buffer.

Re: [android-developers] Re: How do I report a bug to htc?

[Miguel Morales]

You need to use a Lock such as:
http://developer.android.com/reference/java/util/concurrent/locks/ReentrantLock.html
This sounds like a race conditions, as others have pointed out.  These
are usually the hardest to narrow down.

Static variables are not a good idea in general unless you know
exactly what you're doing.

Try adding a lock around your static object, like:

private static Object mMyProtectedVar;
private final Lock mLock = new ReentrantLock();

Then before touching the variable, ALWAYS use the lock like so:

mLock.lock();
mMyProtectedVar.something = something;
mLock.unlock();

Java provides some keywords for making variables and methods thread
safe, although I find a lock to be really clear as to its intended
purpose.

Re: [android-developers] Problem with Exceptions that are thrown deep in the System of my app

[Miguel Morales]

That's the thing.  You don't show any dialogs outside of an activity.
This is not good practice, log the trace.
If you want to be messy, you can have a singleton to which activities
register to.
Then call functions in that singleton.

Re: [android-developers] Re: java Thread class vs Android HanderThread: which is better?

[Miguel Morales]

Also, and correct me if I'm wrong.

AsyncTask uses an internal threadpool to balance background requests.
This is really useful if you making many network calls at once but
don't want to start a new thread for each one.
Also, you do get slightly better performance because with AsyncTask
the threads are already running.  If you implement your own thread you
have the overhead of starting the thread.

Hmm, I see.  I would argue it shouldn't be thread safe, since it
violates the don't touch the UI rule.
But yeah, I highly recommend using showDialog/removeDialog and don't
bother holding an instance of the progress dialog yourself.
This, along with the static activity should work ok if you want a
quick fix.  Or, you'll have to use saveinstance to save status of your
app and handle it accordingly in onCreate().

Re: [android-developers] Dialog dismiss()

[Miguel Morales]

Actually, don't use a ProgressDialog, use Activity.showDialog()
instead.  This handles device orientation.

Re: [android-developers] Dialog dismiss()

[Miguel Morales]

The problem is that you are attempting to update the UI in a foreign thread.
This line: progressDialog.dismiss();

You seem to be using a handler, so just change it to:
handler.postRunnable(new Runnable() {
@Override
public void run() {
progressDialog.dismiss();
});

Don't ever touch the UI outside of the UI thread.

To handle rotation, save a static instance of your activity in your
onCreate() method and remove it on onDestroy();
So, something like:

static MyActivity mStaticSelf = null;

onCreate() {
mStaticSelf = this;
}

Then change your handler code to:
@Override
public void run() {
mStaticSelf.progressDialog.dismiss();
});

Re: [android-developers] Activity GUI updated by thread data: implementation error?

[Miguel Morales]

BTW, this line seems strange:

Message msg = Message.obtain(hRefresh, 1, i1, i2);

The way I do it is by using a bundle with the message and putting
whatever data in the bundle.

Re: [android-developers] Re: How to obtain the tweets of a programatically given Twitter user without registering my app on dev.twitter.com?

[Miguel Morales]

That's pretty much what I suggested.

Anyway, parsing html with java is really easy.  Take a look at
WebHarvest, and libraries like xlst and xpath.
It'll be great programming experience and you'll be able to build all
kinds of scrape services.  But, again, this may not be legal unless
you get permission from the site.

Re: [android-developers] Re: How to obtain the tweets of a programatically given Twitter user without registering my app on dev.twitter.com?

I would say, simply have a backend that scrapes the website.
When the user signs up or whatever, scrape their twitter page.
Then query this backend database from your mobile device.
Probably not very legal though.

Re: [android-developers] Accessing activity implementing methods in another class

[Miguel Morales]

If the class only lives as long as the activity does, then you can
probably get away with passing around the activity.
However, for some basic network code, you might as well just keep it
on your activity class.
For example, you can use AsyncTask or just declare a handler and thread.

Re: [android-developers] Re: [ASK] HOW TO SEND LONGITUDE & LATITUDE TO ANOTHER ANDROID PHONE VIA INTERNET..

[Miguel Morales]

Depending on the specs, and if it doesn't need to be realtime you can
just use http and serialize your data with xml or json.

Ultimately, these are skills any good developer should have and as
such you should try really hard to build it yourself and come back
when you have any relevant android questions.

Re: [android-developers] loadData on a WebView

No, it's never ok to touch any views outside of the UI thread.

Re: [android-developers] Re: Combining Canvas with OpenGL

[Miguel Morales]

the simple way is to use a relativelayout as a base, add the
glsurfaceview, and the regular canvas surfaceview on top of that.
the only thing is that opengl uses a different coordinate system than
the canvas, so you'll have to adjust your math accordingly.

Re: [android-developers] Please see this example when i am taking small file then it works but when taking large video size with 1gb approx then outofmemory error

Look up examples on stream reading a file for java.
The problem is you are allocating an extremely large byte array.

Also, there are many other mistakes in your code.
Don't download the file in the UI thread, see:

Also, don't hardcode paths:

Re: [android-developers] Re: Downloading Files Directly in Webview without it opening the browser

[Miguel Morales]

Actually, it's the other way.  You should return true on
shouldOverride, but only when you've detected that your video link was
clicked.
At the moment, you are returning true, but loading the url to the
webview yourself which defeats the purpose.

Re: [android-developers] Re: Downloading Files Directly in Webview without it opening the browser

[Miguel Morales]

You have to return false on shouldOverrideUrlLoading.
That will prevent the browser from initiating the download.
You have to move the code from onLoadResource there, and return false
if you detect the video link.
The onDownloadStart() is irrelevant if you are going to be handling
the downloading of the file yourself.

You have to make sure you read the data in utf-8 and then set that as

Re: [android-developers] Re: App Crash during HTTP Post

[Miguel Morales]

Post the full logcat trace.
Make sure you're not doing any network operations in the UI thread.
Google 'java multi-part upload' for tips on how to chunk the upload.

Re: [android-developers] need thread on UI / lifecycle Gotchas

[Miguel Morales]

Well, if you use findViewById() in a thread, that's plain out wrong.
The function you posted seems wrong in that it first makes a UI call
in that thread context.
Then it attempts to use a queue to post a runnable to so that
setText() runs in the UI thread.
It's redundant if it's already in the UI thread, and broken if it's in
another thread.

Re: [android-developers] Re: Updating UI from second thread

[Miguel Morales]

Yeah you should redesign your app.  Or, come up with some sort of
buffer solution.
Depends on how often your check function runs, and how critical it is
to the UI interaction.
Maybe setup event listeners for every checkbox so that it keeps track
of an internal structure what needs to be checked, and what doesn't.
Then tell your calculation thread to calculate what needs to be checked.
After the calculation is done, the thread tells the ui what to check.

This *might* work.  Where you avoid the thread/queue overhead and
manipulate the UI in batches.  (and really, you should only be
manipulating what's visible on the screen.)

Re: [android-developers] Re: Downloading Files Directly in Webview without it opening the browser

[Miguel Morales]

Simply set a custom webview client on your webview.
Then detect when your download link was clicked.
Then start a download thread to download your file.
Update the webview accordingly.

If you need any further help, consult the android webview documents.

Re: [android-developers] I can't show random images in the ImageView

Add some logging so that you can see what n is.
Then find out why it's not generating a random number.

Re: [android-developers] Re: onDraw() causing "flicker" when drawing new images

[Miguel Morales]

Perhaps you can try adding a synchronized lock that protects your data array.
Lock it before going into onDraw() and unlock it when finished, and do
the same when calculating your array data.
Do you have a separate thread that calculates positions?

You won't do everything right the first time, but you'll learn a lot.

Re: [android-developers] Re: Android -- the forgotten "real" fragmentation

Ok, so this is weird.  It seems that WAL mode is being activated from
the java code.
I just opened the bad database file in 3.7x and ran the command:
PRAGMA journal_mode=DELETE
to disable WAL.  I was then able to open the database file in the 3.6x version.

Yeah, that's right.  That makes sense.  I was going to try to read the

But seems like that's the culprit of the issue.
There might be a way of turning that off.

Re: [android-developers] Re: Android -- the forgotten "real" fragmentation

[Miguel Morales]

It's still possible despite that, read the link I posted.
If the file was in some sort of unfinished operation where the write
ahead log it will change the file format.
The file would still be readable by 3.7 by not by anything below.

Read the file to determine its version.  Or send it over to the sqlite
people as this appears not to be the expected behavior.
Also, how is this database populated?  Via java code or through the
sqlite command line?
