Android :: Make Java Assert Statement Work?

May 26, 2010

How do I make the Java assert statement work? By "work" I mean that a failed assertion should either stop program execution or at least log the failure. Currently, neither happens. I understand there is a run- time option to enable this (-ea), but I don't know where to specify it. Changing "PreferencesJavaInstalled JREsEdit JREDefault VM Arguments" has no effect, probably because those settings are not used for the Android execution.

Android :: Enable Assert Statement?

Jan 26, 2010

How can I enable assert statement on Android? I have referred to a url: http://android.git.kernel.org/?p=platform/dalvik.git;a=blob_plain;f=d... and done what it said: adb shell setprop dalvik.vm.enableassertions all but nothing happen! The test code is: Log.v("assert 1","1"); assert false; Log.v("assert 2","2"); No matter what I did, "assert 2" will be printed, which means "assert false" does nothing! What should I do? BTW, I use eclipse as IDE.

Android :: Testing A Java Long Value In An If Statement - Does 0 != 0

Nov 2, 2010

I cannot figure out why I can't get this method to enter the if statement.

CODE:.........

Note that the log and debug mode shows that "start = 0"

I also tried

if (start == 0l) {
if (start == 0L) {

What the heck am I missing here? Does 0 != 0?

I'm developing in Eclipse with Java for Android. Thanks.

@methodin - no sorry, that does not work.

@Aioobe - I have a breakpoint under the IF statement, that never gets made.

Here is the actual code I'm running since you've asked.

Android :: How To Make Java And C Programs Communicate Together?

Apr 29, 2010

I have written a command line interface program in the C language. This kind of programs (as you know) waits for user commands typed in the terminal and reacts on depend of them. In fact, the program implements a callback function which parses the command and invokes the appropriate function in order to respond to the user.Now, I have to make a Java GUI (Graphical user interface) for the desktop (Ubuntu) version of this program and then port the same program to the Android Platform (of course the GUI will respect Android framework), so I'm looking for the best way to do it.I have heard about JNI and JNA and I don't known which one will be the best for me. By the way what are the main differences between JNI and JNA.

Android :: Make Adapter Class To Choose .Java File Depending On Firmware Version

Sep 1, 2010

What I did was create two .java files. One that can compile and run on a 1.5 phone (SDK3) and then one that works on 2.0(SDK5) So for this example i'll call the 1.5 file ExampleOld and the new one Example. I was wondering if i just made activity like this if it would work sort of like a "portal" and pick the activity to load depending on the SDK so there is no crash or compile errors. Are there any changes I should make to my code? Maybe anyone out there that's had to do this before.

Android :: Optimize SQL Statement For Sqlite

I'm developing an application that tracks the user's current position and stores it into a SQLite database. Everything works fine, but now I have the problem when querying the database for a track with more than 1000 records it takes nearly 1.5 minutes. On my Desktop it just takes 1 second. I know it's a query with many subselects but I wasn't able to get the right result another way. In my opinion this belongs to the aggregate functions like avg() and sum().
