How can I test if there's a ContentProvider for a Uri ?
I'm currently doing a query on it and checking for a null cursor, but that generates an error in the system log each time, which I don't like to do.

I'm trying to open a file in android like this:
CODE:..........
But in case the file does not exists a file not found exception is thrown . I'd like to know how could I test if the file exists before attempting to open it.
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 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 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_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.

View 5 Replies View RelatedI 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 would like to check whether there is any direct API available to check whether a particular Database exists or not ?
Currently, to initialize data for the first time (not repeatedly), we try of open the db and if it fails we know the database does not exists otherwise it is already created and initialized.
Is there any simple API available to check whether DB exists or not ?
I couldn't find Calendar application in the emulator, is there any plug-in to have all the applications enabled in emulator?
If Calendar app exists, what is the service API for Calendar application supported by android.
I have created a database for my android app which contains static data and does not require update/delete functionality thus when the app starts, I want to check if the db exists and if not then execute my dbAdapter class. I know its a simple if statement but I was just wondering the most efficient way to query whether the db exists.

I need to find out the state of the pending intent, in other word, is this pending intent working or not. Boz i may need to cancel this pending intent, but before canceling it i want to make sure it's active.
But i see no function in AlarmManager can read this status.
I am struggling to find a way to determine if a valid network is available to an app. specifically, if there's a problem making a network connection, i would like to be determine if it's on the client (app) side, or a problem with the remote server. i happen to be attempting a URL connection (using http client) and the wide and varied possible exceptions don't seem like a reliable method. for example, when the network is down on the phone, i received "unknown host exception", which doesn't really indicate the root cause ... it's possible to get that exception with a valid network connection also. at other times i get other exceptions, such as socket exception. is there a way to ask the phone if it's network ready? the other option i thought was to ping a known good server to see if it responds ... with an IP address. kind of a heavy weight option and not foolproof.

I have a database of notes and lists, with three association tables.
Basically, lists are parents of notes and other lists, and notes can be parents of other notes in a outline like hierarchy.
I am using this query to return all notes within a list as well as the number of subnotes each note has.
CODE:...................
This query works just fine, but it's overkill. I don't need to return count(n2.note_id) as Num_Subnotes because I'm only using that value to check if the note has ANY SUBNOTES AT ALL. Essentially it's a boolean value where 0 is false and > 0 is true.
It seems to me that counting all those records is a waste of time when I could just return 1 after finding the first matching value.
Is there a more efficient way to check if count(n2.note_id)>0 in the above query?
I am using a ContentProvider for caching results from a web-service query. It is an HTTP request and the response content is XML. Most of the data is cached, so I simply query the DB, if not found, request from webservice, insert in DB and requery the DB. Thus the response is always a Cursor from SQLiteDatabaseHelper.
I have one result set that is not stored in the DB and since it is 100% transient, but I would like to provide the appearance of it coming from the DB's Cursor. Is there an easy way to do this? For example, if I could project it onto the cursor with a cursor.setValue("string", objectValue) or some other existing implementation.
If not, I will either bypass the DB for this content result, or stuff it into a trivial table that is constantly reused.

View 1 Replies View RelatedI want to add an extra field to the phonebook on android. The field contains a new contact method and when clicked it should start my own application/intent. I have created my own content provider that stores the information. I want to add this contentProvider to the phonebook in the same way organizations and email are added to the phone book. So how do i do this? I tried adding a new contact method but the field KIND needs an integer input which seems to be predefined to some specific methods (EMAIL, IM, ADDRESS etc)
So do i need to add a new type of KIND or can I link my contentProvider to the phone book so that it shows up as an extra field in the phone book?
