Android :: Launching Instrumentation From ApiDemos
Mar 1, 2010
Going through the ApiDemos sample code (in Android 2.1 platform), I saw that there are two activities that make use of the Instrumentation class: ContactsFilter and LocalSample. However, I'm having trouble finding the menu that will launch any one of these activities from the ApiDemos application. I just want to be able to run ApiDemos and hit the breakpoint in one of these Activities so I can understand how the Instrumentation class works. proper navigation in ApiDemos to launch ContactsFilter or LocalSample?

I am running the android-7 ApiDemo sample project on a Nexus One device. I am interested specifically in the Graphics/CameraPreview sample code. The project works fine, but when I select Camera the device displays a Force Quit message. I am not receiving any error information in the debugger. The CameraPreview code works fine in the emulator.

Would like to know the best place to get more details on this tag 'instrumentation' for the manifest file.
<instrumentation android:targetPackage='com.tejasoft.tezzd.mobile.android' android:name='android.test.InstrumentationTestRunner' android:label='TestTezzD' android:functionalTest='true' android:handleProfiling='true'/>
Unable to understand its working, specially, how does the InstrumentationTestRunner find all the test cases and what is the way to write the manifest so that it runs only perticular suite and not all the test cases.

I am trying to write a simple test framework. This is what I want to do: My actual test is an apk file on android device, and I write a TestCase or some instrumentation for that which runs on host side. I trigger the test using adb commands or some IDE.I am able to refer to some examples which does above.Now what I want to know is any way of getting results back using any api available in TestCase or such class.This result can be any string value or an object too.
1. can I use TestResult for this purpose ? I expect it ot be similar to function calland return value from function.i.e. on completion of test I should get back the result in a structured way probably defined by me.Is this possible at all.
2. or return value is always going to be put to stdout? or logcat?
3.how do I parse and collect stdout or logcat prints into a file?
any input would be of great help.

I have separated java code from Android code and have two projects. Android dependent on Java project. Now i want to get the memory trace of the Java project on Android. For that I have created Androd Junit Project implementing Android Instrumentation, and a dummy android project dependent on my actual java project.(as I only want to get memory trace of java project on android).Problem is when I execute Android Junit project, and give a reference of dummy project removing java project dependency, all tests(dummy) run fine.But when I run junit project, with dummy android proj keeping dependency on java project, my application crashes.I get an error message like : "Process crash" not getting any error message in logcat. No clue whats wrong with code.Any help is highly needed.

We are able to run instrumentation tests of Android from the command line on Windows by launching: adb shell am instrument -w <package.test>/android.test.InstrumentationTestRunner. This gives us good results. Using the same architecture, we are unable to run the same in Kubuntu. We have the same setup in Kubuntu. Can someone let us know, if there are packages with same name.. Then what package will the adb shell point? How will the emulator connect with adb shell from cmd line? DO we need to do any changes to do so in Kubuntu?

I use the following instrumentation testrunner command line to run JUnit tests on my project :
code:........
and it runs OK.
I am now trying to pass a property value argument to my instrumentation test runner, something equivalent to the eclipse vm argument -Dcom.myApplication.myProperty="String" The value ("String") of a property (com.myApplication.myProperty) must be defined in the command line. I tried to bend my command line to make this work, changing it for example into :
code:..............
but didn't manage to make it work correctly. Is there a way to make this work ?

We are currently working on an instrumentation test suite which runs on our build server, but while the tests pass on a dev machine using a normal Android emulator, the builds fail on the build server since there we only run a headless emulator with the -no-window flag.The failure occurs when trying to invoke the InstrumentationTestCase.sendKeys() method to programatically open the options menu.We also tried to let the instrumentation test app and the app under test share the same Linux user ID using android:sharedUserId and run in the same process (android:process -- we weren't sure if that was already the case), but still no luck. Does this mean it's currently impossible to run instrumentations which contain key events on a headless emulator, or are we missing something?

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 want to do some automated testcase with Instrumentation . Suggest that my AUT has 2 Activity. After clicking the button in ther first Activity, the second one will be shown with new content base on what we enter in the first Activity.) Instrumentation provides us the function called startActivitySync() and return the Activity object for processing. My question is how we can get the pointer of the second Activity after the it is shown by clicking the button on the first activity.?

I have written an application which calls native methods through JNI. In the native library 4 threads are started. On USB removal, the application is to be closed including the native threads. Upon receiving the USB removal event, we are trying to kill the threads (pthread_kill() ) and then finish (using finish()) the activity. After reconnecting the USB, the application is not launching due to memory corruption. In DDMS, it shows the threads are still attached to bionic. As the threads are not closed, I feel the resources were not released properly. If I reconnect again then application launches and works fine and the same repeats on every launch.
To solve this problem Can I use System.gc() ? Can I use pthread_exit() 1st and then pthread_join instead of pthread_kill ? Whats the procedure in Android to kill the native threads and also the application ? After the application is closed, will it not be listed in DDMS ?

I have an application with three tabs. Through various interactions with the items in the tabs I end up launching other activities. The client has reviewed this and would like the activities launched "within" the tabs, so the tabs remain visible and if the user clicks the tab it goes back to the original activity defined in the setContent function. Is this possible and how would I go about this from other activities? (ie the child activities, not the one that defines the TabHost and has access to call setContent)?

I know this has been asked a lot of times in StackOverflow already, but I haven't quite found a solution yet. My app sends an email with a link in it that when clicked should launch the app. According to @hackbod, the best way to do it is to make use of the Intent URI (see this). Here's my code that sets the intent and puts it in the email body: Code...
