Android : NetworkInfo.getTypeName() - Nullpointer Exception

Mar 14, 2010

I have an activity which shows some List entries. When I click on a list item my app checks which connection type is available ("WIF" or "MOBILE"), through NetworkInfo.getTypeName(). As soon as I call this method I get a NullpointerException. Why? I tested this on the emulator, cause my phone is currently not available (it's broken...). I assume this is the problem? This is the only explanation that I have, if that's not the case I have no idea why this would be null. Code...

Android :: SQLite Query Throwing Exception

Jul 29, 2010

Im trying to get an object form my SQLite database in my Android application. I know that the contact is in the database because when I add it and try finding by ID, it returns the object. When I try finding by first and last name, though, it throws an exception and Im left with a null reference.

Here is the query:

CODE:..........

Ive also tried to find just by first name and just by last name. Same result as above.

The exception is an SQLite exception

no such column: aurelius: , while compiling: SELECT _id, last_name, first_name,
email_address, organization_name, label, label_position FROM contacts WHERE
first_name=marcus AND last_name=aurelius

And also happens when trying to select just first or last name

no such column: marcus: , while compiling: SELECT _id, last_name, first_name,
email_address, organization_name, label, label_position FROM contacts WHERE
first_name=marcus

I created a TextView and put an url to it, using setText(Html.fromHtml("");. Its opening the web page in the built-in browser and when I press back, its coming back to the application.

I don't want to come back to the application, so in activity's onResume(), I call finish(). Its exiting at the first time. But when I open the application again, its throwing some exception.

Any other way to close the application, other than this way.

Android :: Custom MapView Throwing NoSuchMethodException?

Sep 10, 2010

I'm trying to implement a custom MapView. Inside my MapActivity (named mainmap) I have an inner class which extends MapView:

CODE:........

I have my main.xml formatted to find the inner class like so:

CODE:................

Also, in Androidmanifest.xml, I have the appropriate <uses-library android:name="com.google.android.maps"/> entry.

When I try to run my app, I get (amongst other things) in logcat:

CODE:..............

This is caused by this entry I find in logcat:

CODE:...............

If I understand correctly, my app is crashing because Android is saying it doesn't find the appropriate constructor for my custom MapView (the Lmapview class). As you can see above, however, it is defined and it matches the signature it is looking for.

Android :: Android SqlLite ContextWrapper.openOrCreateDatabase() Nullpointer?

Nov 18, 2010

I have created a program, with a service - the service is "START_STICKY". So when i close the program (i am using Advanced Task Killer, to kill programs) the service is restarted automatically, but this presents a problem cause i get an error when trying to call ContextWrapper.openOrCreateDatabase(ContextWrapper.java:203) (see stacktrace below).

I have created a class to handle context, which will return my Activity's context if it is not null, or a fake one i created if the activity's context is null - and the activity's context is null so the fake one is used, i suspect this may be the problem, but have no idea.

In my activity i have a constructor which gives a reference of it self to the contexthandling class, but it seems the activity is not instantiated (not before the service is started at least) when the system is restarting my service.

There is of cause no problem when the program is just started normally, the service starts fine then... which is why i am suspecting the fake context, i created it as follows (and it is referenced in the manifest application tag with android:name=FakeContext):

CODE:...........

Stacktrace:

Android :: FindViewById In A Subclassed SurfaceView Throwing RuntimeException

Oct 9, 2010

This code works fine if I move the findViewById call in to the Activity. Any hints as to why it doesn't work from inside the LearningView class? I've tried moving the TextView inside the com.example.LearningView tag but no joy. I'd prefer to get the TextView from within the SurfaceView subclass as I feel it's more logical to treat the TV as a "child" of the SV.

This is a contrived example I wrote to figure out the problem in a larger application, but the gist of it is the same, and the stack trace is basically the same.

For what it is worth, the findViewById call is returning null, which obviously threw NullPointerExceptions in some attempts to fix this.

As you can probably gather from my attempts I'm flying blind on this one.

Learning.java:

main.xml:

Android :: GL DEBUG_CHECK_GL_ERROR Throwing UnsupportedOperationExceptions For Things That Work

Sep 12, 2009

I turned on DEBUG_CHECK_GL_ERROR for my GLSurfaceView to try to figure out why I'm having a problem on pause/ resume/reload everything, and when I turned it on, I got an UnsupportedOperationException when calling GL11.glGenBuffers() (for creating Vertex Buffer Objects).

Why is it saying that operation is unsupported when:

1) The vertex_buffer_object extension is listed on the target device and my code checks for it before trying to use VBOs.

2) VBOs are working correctly (and really well might I add).

This is on a G1. Yes, I know the G1 is only OpenGL ES 1.0 compliant and I'm trying to use a 1.1 extension, but if the phone lists the extension, doesn't that mean I can use it? Also - the extension works! Does this mean that it works but use-at-your-own-risk, kinda like how SoundPool was in Android 1.0?

Android :: Java Socket Not Throwing Exceptions On Dead Socket?

Jun 29, 2010

We have a simple client server architecture between our mobile device and our server both written in Java. An extremely simple ServerSocket and Socket implementation. However one problem is that when the client terminates abruptly (without closing the socket properly) the server does not know that it is disconnected. Furthermore, the server can continue to write to this socket without getting any exceptions. Why? According to documentation Java sockets should throw exceptions if you try to write to a socket that is not reachable on the other end!

Android :: Out Of Memory Exception

Sep 2, 2010

I have a problem with a strange out of memory exception that only occurs on some devices (mostly HTC Desire). It happens there every time a user starts a certain activity (no matter how - there are two paths to that activity) and i'm really puzzled as to why (i checked for leaks and couldn't find any)...

The error is either thrown when calling setContentView or shortly after.

This is the code block that throws the error:

CODE:.........

As i said - the error is usually thrown when calling setContentView or when calling getMonthTimeStamps()

getMonthTimeStamps is a helper function which creates a list of dates available in the internal database. It creates a couple of (small objects) and returns an ArrayList.

Here is the function:

CODE:.............

I'm not claiming that my code is flawless or perfect, but i really don't understand why this error is thrown. The XML-layout doesn't contain any references to images and not very complicated (textview, spinner, tablelayout).

Here is the error log i received from one user:

I read somewhere not to exception handle when developing in Android, is that true?

If one does need to exception handle are there any logging tools for 2.1 and above?

If shouldn't exception handle, why is it not recommended to at least use the below?
try {body-code} catch (exception-classname variable-name) {handler-code}
