Android :: How To Test App Shown On Market For All Screensizes?
Nov 12, 2009
We have uploaded a new version of our app where we added the following to the manifest: <supports-screens android:smallScreens="true" android:normalScreens="true" android:largeScreens="true" android:anyDensity="true" /> However, we are receiving complaints that users cannot find the app on the market using their HTC Tattoo and HTC Dragon phones. Any ideas what we are doing wrong, and is there a way for the developers to test if the app is visible on the market?

I published several free and paid app in the Market. I recently get several complains from customers about not finding my app in the 2.1 Market. Even if they have bought them before, they can't find it in the market or their download list after updating to 2.1.

I am learning how to program on Android phone. However I am unsure how to make my application work for the different screen sizes and resolutions.
I read the tutorial on the android site and still unsure how to do it.
First I know there are different files so could make a layout for each of the sizes but my problem is most of the screen needs to be dynamically created so there would not be much to put in these files.
So I am not sure how to android to re size dynamic controls based on the screen size.
I have also read it is bad practice to make controls in anything but the xml file as it separates view logic and programming logic. However they never talk about if you need to make these controls dynamically what you should do.
So is there some other way to do it that is considered good practice?
Edit
I get this error when I try to run the switcher application.

To your question: It's dynamic because
the buttons in my example grow and
shrink depending on one of the 3
possibles sizes, because they use
scaled pixel (You probably know that
you don't have to deal with screen
sizes itself). So a scaled pixel
compared to a real a pixel has a size
of 0.75px, 1.0px or 1.5px. Android
automatically and dynamically adjusts
it to the actual size. So you don't
have to care about this in your code.
So if I use scaled pixels then I don't have to worry about different screen sizes?
At the moment I don't know an example
except in games where you have to deal
with "real" pixel. But if you want use
it, multiply it with the value of the
current density. This is your "ratio".
I don't have the example with the ball
anymore but I have another which uses
the same technics. You can run it on
different screen sizes and you will
see that the buttons will always fit
into the layout. You could use the
same technics for your intents. In
this example you can scroll with the
"Scrn" buttons from one view to
another of 4 views. (At the moment
they all have a black background so
you don't see that they are different
views). The "Enter" button exits the
test. It's an Eclipse project. You can
download
So if I want to deal with ratio then I use real pixels and not scaled pixels? What advantage does this give me?
will scaled pixels work with changing from portrait to landscape( ie will it fill up the new found space)?
Finally should I make the controls now through code or is there another way? As I said I am getting data from a webservice that must look like this
checkbox label label
It can be one record or 10,000 records I don't know so these have to be appended to something that is like a window panel( the controls in there get a scroll bar).

I'm writing an Android JUnit test and want to copy/reset a test fixture file (it's an SQLite database file.) If I were within the main application, I know I could just place the file in the assets directory and use getResources().getAssets().open(sourceFile).However, this API appears to be unavailable from the ActivityInstrumentationTestCase2 class.Is there an easy way to copy a file over from the testing PC, or should I just keep a fresh copy of a test fixture on the device and copy it over a temporary file?

I am using ActivityInstrumentationTestCase2 to do some test for an activity. I get a button in the setUp() method like this: protected void setUp() throws Exception {super.setUp(); act = getActivity(); btn = Button)act.find ViewById ( R.id.bike_button ); // this button has been defined in layout} Then I use this button to perform a click in a test method like this: public void testBikeButton(){ //click the bike button btn.performClick();}

I have never used JUnit before, and now I'm trying to set it up on an Android project.My project under test is fairly complex, including some JNI, but my test project, at the moment, is completely trivial. I have found many examples (that look totally different) online of how to make a test project, but it seems that no matter which one I follow, I get the same results.Here's my JUnit project code:package com.mycompany.myproject.test;
import android.test.AndroidTestCase;public class SimpleTestCaseExample extends Android TestCase {public void test_testOne() {fail("Just Always Fail");When I run, I see the following in Logcat:
stdout INSTRUMENTATION_STATUS: numtests=2
stdout INSTRUMENTATION_STATUS: test=test_testOne
stdout INSTRUMENTATION_STATUS_CODE: 0
stdout INSTRUMENTATION_STATUS: id=InstrumentationTestRunner
stdout INSTRUMENTATION_STATUS: current=2
stdout INSTRUMENTATION_STATUS: class=com.mycompany.myproject.test.SimpleTestCaseExample
stdout INSTRUMENTATION_STATUS: stream=
stdout INSTRUMENTATION_STATUS: numtests=2
stdout INSTRUMENTATION_STATUS: test=testAndroidTestCaseSetupProperly
stdout INSTRUMENTATION_STATUS_CODE: 1
stdout INSTRUMENTATION_STATUS: id=InstrumentationTestRunner
stdout INSTRUMENTATION_STATUS: current=2
stdout INSTRUMENTATION_STATUS: class=com.mycompany.myproject.test.SimpleTestCaseExample
stdout INSTRUMENTATION_STATUS: stream=.
stdout INSTRUMENTATION_STATUS: numtests=2
stdout INSTRUMENTATION_STATUS: test=testAndroidTestCaseSetupProperly
stdout INSTRUMENTATION_STATUS_CODE: 0
stdout INSTRUMENTATION_RESULT: stream=
stdout Test results for InstrumentationTestRunner=..
stdout Time: 0.07
stdout OK (2 tests)
stdout INSTRUMENTATION_CODE: -1
But, I get the following in the Console:Launching instrumentation android.test. Instrumentation TestRunner on device emulator-5554 Collecting test information Test run failed: No test results I have tried a variety of different things, messing with the basic TestCase class, or the TestSuite class, or a variety of other options. I tried to just go for the most trivial example because I'm really still trying to learn how this works.Whatever I try, I see this error.

I'm working on a school project and I'm researching testing possibilities for Android applications. On this page: http: // developer . android . com/ resources / tutorials /testing /hello android. Google writes about a unit test. Is this really a unit test? A Unit test will not integrate all classes and will not test in his context. So my opinion is it is not a Unit Test but an Integration Test.

I have a project (that compiles and runs in the emulator.) I have a test project that tests part of this project. This test project also compiles with no problems, but when I try to run (test) it in the emulator, I get a NoClassDefFoundError exception on one of the classes my test class tests (I hope that made sense!) when it starts to run in the emulator. This is coming out of the adb log. I looked in the bin directory (of the test project) for the missing class, but could not find it... Should it be there? I found no reference (apk, etc) of the project I am trying to test either in the test projects bin directory. How does the test project get the classes it needs to test against (in the classpath, I assume.) How do the tested classes get moved to the emulator? I did try running the app before testing, so I know it is installed and runs correctly. BTW, I am using netbeans with the nbandroid plugin.

I followed the instructions from the google hellomapview tutorial. I get a working mapview etc. But the two items that are added to the map are not shown. It seems they are there somewhere because tapping at the specified location shows the message that was added to the items.
Here is my source code. It should be very close to the google tutorial source code.

1/I don't want to notify user if this one is already running my app in foreground,is it possible before create nofification to check if my app is not in front? 2/if app is in background, is it possible to bring last state in front? I know that Os can destroy some Activity, but is it possible to restore last state, don't start a new Intent? because if i start a new Intent and i push back, old Intent appear it's not very beautiful to have 2 identical intent launch...............

If the BACK button is pressed when the soft keyboard is being displayed, no Back keycode event is generated (when it's not shown, and Back is pressed, then my View's onKeyDown()/onKeyUp() methods get called back).
Is this expected behaviour? I'm trying to catch when the IME is hidden upon BACK being pressed. I'm currently working around this in the endBatchEdit() method (I'm implementing BaseInputConnection).

The application I have uploaded into my cellular device is shown without the pictures I have insert to it. While the APK runs without problems on emulator when installed on Motorola milestone picture and icon doesn't shown as they were on emulator.
Steps I have done in order to install:
- I have inserted the xxx.apk file into the device via usb
- I downloaded an apps installer via the Market
- I opened the app using the installer and instead of picture an white background appeared
when I opened the xxx.apk file using file system I found the pictures.
Note: even an application icon weren't appearing. Apparently the res library having problem to be bined to application.
- I might need to add something to my appliction manifest?
- I might need to change something on my device ? (I already made a change and enabled user's not Market application).
I also tried an example as shown in hello android book the same example worked perfectly on the emulator where on my android device (Motorola milestone) the picture and icon weren't shown. Please tell me what I might be doing wrong guys I need to apply my project back at uni (I was the only one in uni who did it on android and in my country most of pep don't even know what android is so getting help outside of forum's like this is not an option).

I've seen this posted before however I'd really like to revisit it. In dealing with a small res device I would like to hide the status bar, my current solution has been to make it transparent and 'make a mess' of the framework and xml so that certain icons are no longer shown, for example the battery icon only shows a png when it's low, the ticker font is transparent etc. I'd much rather do this the proper way, via the source in android 2.1 So who has ideas for; Making the status bar hide when the launcher is open? not having the notification ticker at all? Disabling the status bar completely?

It is perfectly legal for a URL to contain an embedded space in certain situations, such as in this example:
http://maps.google.com/maps?q=37.265632,+-122.2468(10:33 PM)&iwloc=A&hl=en.
But when this URL is pasted into the body of an email from Android code, it breaks at the space, rendering it useless as a clickable link. Is this a bug or a feature?

I feel silly asking this but can't figure it out. I use my gmail account specifically to get messages from a google groups boating forum. I have a work account w outlook and I use k-9 on my phone for that. I know that google doesn't have folders, but labels. I created a label 'xyz' for all email coming from that google group. My question is, how do I not have all these items show in my inbox?
In outlook, I can set up a rule that all email coming from abc@xyz.com goes into the xyz folder, and doesn't clutter my inbox. How do I do this in gmail. I have all my email messages showing that they belong to xyz label, so my rule is working, but I want them not showing in my inbox.

I'm playing some MediaPlayer instances at the same time (4 or 5) but sometimes when I try to start a new media player it doesn't work and an error is shown on the log:
E/AudioFlinger( 1073): no more track names availlable E/AudioTrack( 1073): AudioFlinger could not create track, status: -12 E/AudioSink( 1073): Unable to create audio track E/VorbisPlayer( 1073): mAudioSink open failed
It also happens when there're only 3 or 2 MediaPlayer playing at the same time. What does it mean this error? How can I workaround with it? Actually checking the isPlaying() after the start() call does not seem very helpful as every call returns true. I've to say that every MediaPlayer is created once via MediaPlayer.create.

Has anyone seen a a onItemSelected not being called when using a spinner inside a listviewActivity. I have the code below Inside a listViewActivity. The spinner is shown on screen by pressing a button (not the spinner) which in turn calls performClick() on the spinner. When I select an item from the spinner the onItemSelected function is not called. Does anyone know why this might be? Code...

I have a few elements in a RelativeView with the align bottom attribute set, when the soft keyboard comes up the elements are hidden by the soft keyboard. I would like them to move up so that if there is enough screen space they are shown above the keyboard, or to make the section above the keyboard scrollable so the user can still see the elements.

I have a problem when trying to see use the Android for development on Ubuntu. The device is shown as offline. Although it detects the device.
when I type % adb devices List of devices attached HT845GZ50600 offline
I am using: Ubuntu 9.04 (Jaunty)
Few things I tried:
1. I have changed the 50-android.rules file and reloaded the udev. [ as suggested by docs] 2. 51-android.rules ( if there was another 50 then this would have worked) and it worked for some users [ diff thread in the forum] .
2. I also killed adb server and restarted it.
3. It works on Windows, but I want to develop on Ubuntu ( and curious why it doesnt work).
