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?

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 have a GestureOverlayView over the top of a TextView. The TextView has Linkify.addLinks(tv, Linkify.ALL) called on it.
If you click on an URL in the TextView the following exception is thrown Running 2.2 (apparently a pre-release version)

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.

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:

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.

I am trying to execute following code:
CODE:........
Both above lines are throwing exception W/System.err(762): java.lang.SecurityException: Injecting to another application requires INJECT_EVENT permission.
Do we need anything else too to get it working ?

I have noticed that there is a thread on tips for getting web pages from a PC to the phone for viewing ((How to) get a web page from computer to phone. - Android Forums). I don't have a problem with this and I use the qr code extension method with Firefox. What I would like to know is if anyone has come up with an equally simple & quick way to throw a web page found on the phone to their PC? I know of some ways to do it..I'm looking for the most time efficient/easy way to do it.

Anyone else experiencing this problem or know of a solution? I have a Digicert signed https certificate that is throwing an SSLException (Not trusted server certificate). This doesn't make any sense as Digicert is a recognized certificate authority. I can connect to my https url without a problem via IE, Firefox, and Safari so they appear to have no issue with the certificate. Here's the code I'm using. Very simple stuff......................

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!

I'm new here and I want to start things out by asking you guys about certain things Android is lacking. As many of you know, the OS is only a year old but is rapidly evolving. I don't own an Android device yet (I currently have the HTC HD2). I'm waiting for Android to grow considerably bigger so I won't have to worry about future upgrades. Android is an awesome OS and a lot of devices carrying the OS is very good, but I feel there are some things is still lacking. In your opinions, what are the things still lacking? I can only think of one (only because my brain is dried out from work): full flash support. I guess you can also add: more memory but this is more of a micro-SD card issue instead of Android.

I just about got this, but I have a small problem in the order of things going off.
Specifically, in my thread() I am setting up an array that is used by a Spinner. Problem is the Spinner is all set and done basically before my thread() is finished, so it sets itself up with a null array.
How do I associate the spinners ArrayAdapter with an array that is being loaded by another thread?
I've cut the code down to what I think is necessary to understand the problem, but just let me know if more is needed. The problem occurs whether or not refreshData() is called.
Along the same lines, sometimes I want to call loadData() from the menu. Directly following loadData() if I try to fire a toast on the next line this causes a forceclose, which is also because of how I'm implementing ProgressDialog.
CODE:...............
I tried changing onCreate() to the following after Jims suggestion.
Not sure if I did this right, still doesn't work:
CODE:....................

To get pictures/music/apps onto your phone from your PC and avoid having to use a USB cable, an easy method is to install dropbox from the marketplace and install on your computer. You can then easily place any file into the dropbox on your computer and it will automatically sync. A great feature of the android dropbox is that is allows instalation of .apk files as well, saving time all round. Thought I'd pass on this bit of advice here as i found it to be very useful. If your looking to register with dropbox, follow the link below.
