Android :: How To Test Content Providers On Android?
Aug 1, 2009
I am trying to test my DB using Provider Test Case2<T>. I can see the test DB being created. As such I suppose, the tested content provider should use the test DB. But as soon as I try any calls against the Mock Content Resolver (or the one created with new Resolver With Content Provider From Sql), I get an Unsupported Operation Exception. This is documented for the Mock Content Resolver as normal behavior. As such I am a bit unsure on the purpose of the Provider Test Case2. How do you test your content providers?

This may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?

Everything is working fine, I can access the provider. The problem is that I want to create a demo version of my app and I want it to share the same content provider so when the user install the full version, the data is kept in sync. Also, it should be possible to install only the full or the demo version. Therefore, I have to include my content provider in both.Now, when I try to install both apps error message, obviously because both AndroidManifest declare the same content provider.Is there a way to tell in the Manifest that this content provider should be used only if it doesn't already exists ? Or another workaround ?A solution would be that the full version migrate the data from a demo content provider to the full version content provider, but I would rather avoid that.

I have a doubt regarding content provider.My doubt is I create a app1 that creates Content Provider and in second application(app2) i am using app1's content provider methods(like insert, update etc). It's working fine but i want to set some permissions in app1, so that if any other app wants to use that provider it must have to get this permissions(<uses- permissions) then only it should be able to use providers.

I am having trouble understanding content providers in Android. Do you use intents to call content providers as well as managed queries?
Also, an activity has an intent filter. The intent filter has a element which has a mimeType attribute. How does Android know which content provider this mimetype is referring to?
The tag in the manifest just lists an authority but not the full content_uri. Further, the content_uri is typically defined in an encapsulated class that seems to only consist of constants but no methods, so I don't see how that links over to the content provider class.

Is there a way to programmatically list all available content providers on a device? No real use case, I just thought it might be neat to see what apps I have installed on my phone that have exposed content providers.

I have a plethora of data which is currently stored in 1000 different very small text files, I want to store this data in an SQ Lite database as I feel that this will be more space efficient and hopefully time efficient as I presume a database query is faster than opening and parsing a text file (please stop me now if this isn't the case!). The data does not need to be available to other applications and will be used internally only. My first question is whether or not to create a content provider anyway, is there any benefit to this? My second question is where to initialize the database, is it possible to ship an application with a database included already populated? Do I have to populate it in the on Create method of the SQ Lite Open Helper subclass? If I have to include the 1000 text files and read, parse and insert the data at inst all time I have a feeling this would be slow. Is it possible for me to populate the database now, dump it to a single file and then bulk insert from the file in the on Create method?

Just found out that I don't need content providers if I don't need to share data with other applications. But since the examples I've seen all use content providers, I'm not sure how to proceed without them and populate activities with data derived from accessing my application's database directly.

I am in desperate need of good tutorials on Content Providers in Android. I have been searching in the web for the tutorials but none could give me a clear idea on how content providers work. I'll be grateful if anyone can provide me with sample codes of the projects that implement content providers...

I'm attempting to make a custom Content Provider so that more than one application (activity?) has access to it. I have several questions about how to do this, How do I declare in the code that it is a Content Provider? How do other applications (activities?) use or import the Content Provider?

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'm just looking at the Android's native IM app and wondering if it's possible to create new providers? I know other people have written seperate IM clients but it'd be great to add to list in the native IM app.
The 3 I'd like to work on is Facebook, MySpaceIM, Skype.

My application requires current location of the user. For this I have implemented the code and I am able to get the current location. The code tries to get the best provider first and then fetches location information. The problem is that the current location is returned from NETWORK_PROVIDER if GPS_PROVIDER is disabled. If both NETWORK_PROVIDER and GPS_PROVIDER are enabled then the best provider will be GPS_PROVIDER and this takes too much time to get the current location.
So, is it alright if we set the location provider as NETWORK_PROVIDER only so that it will not matter whether GPS_PROVIDER is enabled or not.

I want my app to be able to retrieve a fine location, but also to be able to get it's location as quick as possible. What I'm trying to implement is something like the way it works in maps, i.e. it gets a coarse location via network and then refines that location using GPS.
If I set the criteria to ACCUARCY_FINE it automatically tries to use GPS to get the location. The problem is that if a user is indoors then this may take several minutes, if it finds it at all. Is there an easy way to tell the manager to use network provider and then GPS, or will I have to do this myself? If so what's the best way to go about this? Will I need to thread it in some way?
I'm sorry if these questions have been answered already. I've found various location examples but none that seem to do what I'm asking.

I'm trying to get a list of the available cellular network providers. Unfortunately i can't find any service or class that might help me out :( Does anyone have an idea on how to manage this? It has to be possible since you can see the list when you go to the settings on your Android device..

How do I enable/disable GPS and Wifi providers? I check to see if they are enabled by using this code:
locationManager.isProviderEnabled("gps") locationManager.isProviderEnabled("network")
If both are false, I'd like to turn enable the GPS provider and/or the Network provider so that the above checks would return true. Is this possible? If so, what permissions does it require?

I'm considering switching from T-mobile to verizon for this phone. I was this close to getting the motocliq but this device seems to be much better as long as the keyboard is functional since I'm not even a social networker. How many of you are considering switching carriers for this phone and do you think its worth it?
Is it true there's a 30 day buyer's remorse period on verizon so if I just get it and don't like it for whatever reason, I'm safe to remain with t-mobile and not be committed?

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.
