[android-developers] Instrumentaion - running multiple istrumentation simultaneously
Hello All,
This is what I have,say:
TestCases : TestCase 1 to TestCase10 , all have several test methods
in it (all extends base class InstrumentationTestCase)
TestSuite:
TestSuite 1 - Adds 'TestCase 1 to TestCase10' in
its suite
All of the above is in single APK.
Instrumentation Runer used is - android.test.InstrumenationTestRunner
itself.
--
This is what I am trying:
- I launched Emulator having above apk
- I opened three terminals , two to run instrumentation and third one
to log results i.e.
Terminal 1 : adb shell am instrument -w -e class
com.InstrTest.TestSuite1 com.InstrTest/
android.test.InstrumentationTestRunner
com.InstrTest.TestCase1:
com.InstrTest.TestCase2:
com.InstrTest.TestCase3:
com.InstrTest.TestCase4:
com.InstrTest.TestCase5:
com.InstrTest.TestCase6:...INSTRUMENTATION_RESULT:
shortMsg=Process crashed.
INSTRUMENTATION_CODE: 0
Terminal 2:
terminal 1 : adb shell am instrument -w -e class
com.MyInstr.TestSuite1 com.MyInstr/
android.test.InstrumentationTestRunner
DDM dispatch reg wait timeout
Can't dispatch DDM chunk 52454151: no handler defined
Can't dispatch DDM chunk 48454c4f: no handler defined
com.InstrTest.TestCase1:
com.InstrTest.TestCase2:
com.InstrTest.TestCase3:
com.InstrTest.TestCase4:
com.InstrTest.TestCase5:
com.InstrTest.TestCase6:
com.InstrTest.TestCase7:
com.InstrTest.TestCase8:
com.InstrTest.TestCase9:
com.InstrTest.TestCase10:
Test results for
InstrumentationTestRunner=.
...
Time: 11.191
OK (10 tests)
Terminal 3: This is what I saw in the middle of logcat dump:
..
..
..
D/ActivityManager( 564): Uninstalling process com.InstrTest
D/ActivityManager( 564): Force removing process ProcessRecord
{4379dad0 785:tr.nth/10041} (tr.nth/10041)
W/ActivityManager( 564): Crash of app com.InstrTest running
instrumentation ComponentInfo{com.InstrTest/
android.test.InstrumentationTestRunner}
D/ActivityManager( 564): Uninstalling process com.InstrTest
D/AndroidRuntime( 776): Shutting down VM
..
..
..
Queries:
1. Is not it possible to run instrumentation in above manner?
2. I tried another TestSuite2 in terminal 2 instead of TestSuite1 ,
this also gave same results.
My aim is to run 2 testsuites parallel, using same apk. Is it
possible?
Or I have to use two different apks? Is there any way that this is
possible?
Any input would be appreciated.
Regards,
Dev

[android-developers] Rotating image using setImageMatrix()
Hi all, I rotate image using setImageMatrix() function. I first use getImageMatrix() function to get matrix then i use matrix.postRotate (90). Rotation works fine.

[android-developers] Re: Instrumentaion - running multiple istrumentation simultaneously
More to add on the same:
I tried 2 different apk's with test suites I want to run.
i.e.
apk1 has testsuite1
and apk2 has testsuite2
tried running them in two terminals simultaneously.
What I saw was, though I did not get any crash, they don't run
simultaneously.
Execution was one followed by other, I continued getting "DDM dispatch
reg wait timeout
Can't dispatch DDM chunk 52454151: no handler defined " messages too.
So Is not it possible to run two instrumentation tests together?
Regards,
dev

[android-developers] Re: concurrency of AsyncTasks
Interesting issue. I can see the need to make this configurable
though. In some cases it would be nice to make sure that these
background tasks do not run concurrently as concurrency issues can
result.
For example, I might have a URL fetch tied to a user interface
button. When the URL returns, I update an internal model with new
data. If the fetch is slow to load, the user will keep mashing the
button, resulting in multiple requests. It would be nice to have
those requests single threaded, rather than having to worry about 5
requests returning asychronously, and having to synchronize my model
update code.
Also, as it appears that the default is currently single threading, a
change to make the pool larger could break any apps that depend on the
single threading behavior.

That's great. Thanks. Unfortunately this tells me I have to live with what I have since it's beyond my control. I don't mind if other email clients (gmail or whatever) pick up the intent - it's the user's choice - I'd just rather not pick up apps that are not especially suited to my purpose. So it goes.

[android-developers] How to draw tracks on gmaps in apps
I've been struggling to efficently draw tracks over the top of maps embedded in my app. I've been redrawing the track with the ondraw method however as the number of points the app and eventually the phone crawls to a halt and I get a bunch of force close/wait messages as a result. I've been toying with the idea to some how draw the track on a bitmap or canvas and every time GPS updates, update the canvas/bitmap and display it as an overlay but I don't really know how I would or should go about this.

楊健 wrote: > How can i save a Bitmap instance to a *.bmp file?Anyone knows? Option #1: Don't do it. So, for example, if this is a question of uploading data to some server, let the server do the conversion from PNG. Option #2: See if there is a way, through the implementation of Bitmap in the open source code, for C/C++ code to get its hands on the raw byte array that is the image. Then, use the newly-released NDK to write yourself a utility method somewhere that works like compress(), but writes out BMP files, perhaps using some existing BMP-encoding C code you find somewhere. > Is it strange that we can only save a bitmap instance to a png or jpg > file? No. BMP files are huge (compared to a PNG edition of the same image), and huge is not something you typically want on a mobile phone. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy _Android Programming Tutorials_ Version 1.0 Available! --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: Default number of Views constructed for a BaseAdapter?
Have you tried *not* caching the component views in your ViewHolder

You may find that the list is re-using objects, and your image issue
is simply an artifact of that.

Thanks. But I need help in combine your 2 ideas together.
In creating file using MODE_WORLD_READABLE , it returns a reference of
FileOutputStream, not File, how can i get call the getAbsolutePath?
File#getAbsolutePath() to get the fully-qualified path.
try {
FileOutputStream fos = openFileOutput
("temp-picture",
MODE_WORLD_WRITEABLE);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block

File f = getFileStreamPath("mypicture");
Just because you use openFileOutput() does not mean you are forevermore
blocked from calling getFileStreamPath(). Just call getFileStreamPath()
on the file you just created.

Thank you. I appreciate your help. I tried your suggestions. But I
still cant' get it to work.
I am trying to launch ACTION_IMAGE_CAPTURE activity using the
MediaStore.EXTRA_OUTPUT parameter to specify the URL of the captured
image.
Here is my code, but my activity's protected void onActivityResult()
never get called.
Can you please tell me what am I doing wrong?
Intent i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE, null);
File f = getFileStreamPath("temp-picture");
(new File(f.getParent())).mkdirs();
String mTempFilePath = f.getAbsolutePath();
f.delete();
FileOutputStream fos =null;
try {
fos = openFileOutput ("temp-picture", MODE_WORLD_WRITEABLE);
} catch (FileNotFoundException e) {
} finally {
if (fos != null) {
try {
fos.close();
} catch (IOException e) {
}
}
}
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.parse("file:/" + mTempFilePath));
i.putExtra("outputFormat",Bitmap.CompressFormat.PNG.name());
System.out.println (" catpure
picture 4");
// i.putExtra("crop", "circle");
//i.putExtra("return-data", true);

Install an application that responds to that Intent.
There is no video player on Android by default, AFAIK. However, there
may be third party video players that will honor your request, depending
on what mCurrentVideoFilename is.

/**
* Demonstrates required behavior of saving and restoring dynamic
activity
* state, so that an activity will restart with the correct state if
it is
* stopped by the system.
*
* In general, any activity that has been paused may be stopped by
the system
* at any time if it needs more resources for the currently running
activity.
* To handle this, before being paused the
* {...@link android.app.Activity#onSaveInstanceState onSaveInstanceState
()} method is called before
* an activity is paused, allowing it to supply its current state. If
that
* activity then needs to be stopped, upon restarting it will receive
its
* last saved state in
* {...@link android.app.Activity#onCreate}.
* In this example we are currently saving and restoring the state
of the
* top text editor, but not of the bottom text editor. You can see
the difference
* by editing the two text fields, then going to a couple different
* applications while the demo is running and then returning back to
it. The
* system takes care of saving a view's state as long as an id has
been
* assigned to the view, so we assign an ID to the view being saved
but not
* one to the view that isn't being saved.
* Demo
