I'm developing an Android application with database storage.
I want to test some classes that I use to access database.
I've found ActivityInstrumentationTestCase2 to test Activities but I haven't found anything to test classes.
How can I do that? I haven't used jUnit before.

I'm developing an Android application.I have a package to access SQLite3. It isn't a ContentProvider. How can I test the package's classes using JUnit?
View 1 Replies View RelatedI'm trying to start unit testing on my application (should have done so from the beginning). I've got an Eclipse project structure set up and everything seems to work well, but...
I'm subclassing SQLiteOpenHelper to access the application database. This works well for the application, but when using the same class in the unit tests, it writes to the same database as the actual application. This is obviously rather irritating, since unit test data shows up when developing and testing the actual application.
What's the best way to make the SQLiteOpenHelper class write to a different database file when being called from the unit tests?
I wrote a simplest test based on android.test.ActivityInstrumentationTestCase2.

I've been exploring the Android test package and I'm very confused on how to implement functional testing for endpoint-to-endpoint.
Consider the example below, I have 4 activities: 1. A Contact List Activity 2. A View Contact Activity 3. An Add/Edit Contact Activity 4. A Sync Contact List activity
I want to automate a few tests that will go through multiple test cases simulating a user experience: From launching the application, to selecting 'Add contact;' opening the add contact activity, entering data, saving it, going back to the list activity, and verifying the new contact was saved properly.
As I understand it, ActivityInstrumentationTestCase<T extends Activity> and ActivityUnitTestCase<T extends Activity>, are only useful for testing single activity functionality.
But what if I need to switch between 2 or more activities inside a single functional test case?
I'm developing a Android AppWidget for my application. For updating my appwidget I need to download data from network. But when I try to do that in onUpdate method, my appWidget is killed by Android system. I learnt that time consuming operations can't be done in receivers so I launched a service from onUpdate method and launched a thread from that. But still the problem persists.
Can anyone please let me know how to do network operations in Appwidget?
OK I'm reading this page:
http://developer.android.com/guide/appendix/faq/commontasks.html#thre...
The code is as in the example (see below). In my application, the worker thread has done loading of large bitmaps, and I need to notify the UI thread the filename of the bitmap that was loaded as they get loaded. How can I notify the UI thread of the filename of the bitmap just loaded? I can see anyway to for updateResultsInUi() to be able to take a parameter from the example below.
public class MyActivity extends Activity {
[ . . . ]
// Need handler for callbacks to the UI thread final Handler mHandler = new Handler();
// Create runnable for posting final Runnable mUpdateResults = new Runnable() { public void run() { updateResultsInUi();
} };
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
[ . . . ]
} protected void startLongRunningOperation() {
// Fire off a thread to do some work that we shouldn't do directly in the UI thread
Thread t = new Thread() { public void run() {
mResults = doSomethingExpensive();
mHandler.post(mUpdateResults);
} };
t.start();
} private void updateResultsInUi() {
// Back in the UI thread -- update our UI elements based on the data in mResults
[ . . . ]
}

The HTML 5 canvas supports composite operations (See here).
Is this possible in an Android Canvas? I scanned the API of the Canvas class but couldn't find anything useful. I need at least the composite operation "source-in" or (if this isn't possible) "source-atop".
Is it possible to have low level access in Android with Java/NDK to create for example card scanner like scandisk or card defragmenter? I move a lots of stuff around my card and it gets fragmented quickly. I have experience with FAT32 defragmenting on Windows, but I'dliek to do this on Android.

View 2 Replies View RelatedI've read this in a few articles, that one should avoid floating point operations within the physics update of a game.
But how do you really achieve this? Surely all half decent games are going to involve this kind of maths?
Does it mean, convert all your variables to int, or use double instead, or simply just cut it out as much as possible?
I've downloaded the android 4.4, but when i'm going to settings, security, the program crash the operations.

View 2 Replies View RelatedI'm having troubles with ADT and JUnit Testing.
When I use HttpClient classes, my JUnit tests fail with errors like: java.lang.NoClassDefFoundError: org/apache/http/client/HttpClient.
I run my tests in Eclipse as "JUnit Tests" (not "Android JUnit Tests") with the "Android Test Launcher". An idea about how to resolve this problem?
Been slowly building my app and now JUnit is crashing regularly with logcat as below.
There are no other real hints. No relevant code as this can happen at multiple points of the code. There are no other errors or exceptions thrown. As far as I can tell there is plenty of memory left and my app does not appear to have any leaks I can find during a run outside of JUnit.

As the first step of the port of my existing Java swing application to Android, I'd like to get the non-UI logic unit tests running on the Android device. The unit tests are written against JUnit 4. It looks like Android 2.2 comes with JUnit 3 as the default. Is there an easy way (or any way) to bootstrap JUnit 4 as the test runner?
I am using IDEA as my dev environment, but it doesn't appear there's any settings that will allow me to specify JUnit 4.
So i was wondering if its possible to for an application that i would write to be constantly running in the background and alter regular phone operations. For example this could be something like as soon as you receive a text from anyone you forward it automatically to another number. Is something like this at all possible? Just to be clear I don't want to solve that particular problem through some other means, just want to know if apps can accomplish that. Also if that is possible is it possible for an app that i write to alter more immediate and instant things, like an incoming call.

I am developing a simple android application using eclipse.I wrote a JUnit TestCase for a class I wrote.One particular test compares two 2d arrays so see if they are equal. If they are not equal the test fails.When the test fails I would like to print out the contents of the offending array to see what went wrong. I have tried System.out.print and it doesn't show up in the console or JUnit results.What am I doing wrong?Is it even possible?
View 1 Replies View RelatedAfter following some instructions on Diego Torres blog I am able to test my classes using the regular Eclipse JUnit test-runner, however I also want to be able to run my unit tests from within the emulated android environment. For now this should make no real difference since the classes I am working on do very basic numerical or networking tasks, but obviously anything which involves the UI or Android API specific functions can only ever be tested on the emulator.
I set up a new run configuration of type AndroidJUnitTest wich uses the ndroid.test.InstrumentationTestRunner, however whenever I fire up the test I get the following error in the console:

View 2 Replies View RelatedIt appears that Android supports JUnit 3 out of the box.�However, I have some pre-existing JUnit 4 unit tests that I'd like to try on Android. I've tried adding the JUnit 4 jar to eclipse and compiling/ running the tests by pointing a standard JUnit run against them, but nothing seems to happen.�There's no evidence in the eclipse console or the Android emulator that any tests have been run.
Can anyone with knowledge about this subject comment?�Is it even possible to run JUnit 4 tests under Android, and if so, is there a step-by-step explanation as to how to achieve this (preferably under Jetbrains IDEA IDE, and/or Eclipse).
The problem is, that I wanted to write a JUnit-Test for some of my classes - but this stupid Anroid SDK does always lauch this absolutely lame AVD!
So I came up with the idea to move all my non-Android related classes out of the actual Android project into standard Java project. There I can easily test my classes and by adding this standard Java project to the BuildPath of the Android project, I can easily access and use my classes: no error is shown in the IDE - everything is fine.
But if I launch my full application in the AVD, it exits with following exception: NoClassDefFoundError!
I found out, how to run a normal test from an Android project. But why is it not possible to reference to a non-Android project? Regarding code reuse, this is really big disadvantage!
I do a lot of Android app testing. I use my regular phone, where I have my contacts and my regular gmail account. I never used a credit card on this account. I mostly use APK files to install the apps. I have 2 questions:
1. can an app display some permissions when installing, but have others hidden permissions ?
Example: instal APK file > says permissions "Network access" and that's it.
Can this app also read my data or make phone calls, even though those permissions were not displayed ?
What is I use an app to display ALL permissions ? Can it really display all or is there an way to still have hidden permissions ? I use Android 2.3.7 root and 4.1 no root.
2. Can an app make unauthorized hidden operations, like place phone calls or send texts or steal my gmail password ?
Like I said, I never used a credit card, so at least that's not a problem. But I have my SIM card - can an app place a value added call or SMS (I don't know the exact English term - expensive call), without me knowing about it ?
Or compromise my Gmail account ? I have an alternate email for recovery.
