Got Hooked Up With Nullpointerexception
Feb 25, 2013
I am getting a nullpointerexception. Only thing is, it doesn't appear to be there at all devices, so is rather strange to me.. an idea is that it would be Bitmap, but since I declare it myself I guess this is not correct? Since it is not happening on my own device I just have to be sure...
[HIGH]Bitmap bm = BitmapFactory.decodeResource(C.getResources(), resId);
Bitmap result = mark(bm);
public static Bitmap mark(Bitmap src) {
int w = src.getWidth();
// int w = 150;
[code]...

I'm on Aloysius v6 and just flashed the 2.41.00.03.10-eris.zip radio update. Ever since then when I connect to my computer with the USB cord, it constantly reboots.

Picked up my HTC EVO on the 4th, and had Sprint order me the HDMI cable. Came last night. Tried to hook it up to my 37" 08' Samsung LCD HDTV, but was only getting AUDIO through to the TV, no VIDEO? I tried all three HDMI outlets on my LCD HDTV but got the same result on each one? Anyone know whats going on here? Anyone else experience this? Anyone have success trying to do what I was trying to do?

Wondering if there's an app that works really well to stream music from my phone (HTC Evo 4g LTE) to my speakers that are hooked to an airport extreme. The ones I have been able to find on the market don't work very well.

Cannot figure out how to STOP Droid from redialing a BUNCH of times my last call made -- when I have the VErizon bluetooth hooked up.
Frustrating & embarrassing!
Suspected bluetooth getting "pressed" when stuffed in my purse - bur can't replicate (make it happen on purpose.)
Have tried changing settings - no luck.
Something about putting Droid & bluetooth in purse makes 6 redials +++ happen.

I am (supposedly) catching NullPointerException and returning 0 if that happens. But occasionally I get NullPointerException failure anyway. Is catching it this way no enough to prevent this failure?
private char getCharBehindCursor (int offset){ // get a single char behind cursor + offsett CharSequence cSeq; InputConnection inputConnection = getCurrentInputConnection(); if (inputConnection != null){ try { cSeq = inputConnection.getTextBeforeCursor (offset + 1, 0); } catch (NullPointerException npe) { /* failure*/ return (char)0; }
if (cSeq.length() == offset+1){ return cSeq.charAt(0); } } return (char)0;

I'm using a lazy image loader for my ListView with the following code inside getView():
CODE:.........
And the following inside the AsyncImageLoader class:
CODE:........
For an unknown reason to me, after to switched from using the common SQLiteOpenHelper to a custom one which allows me to store my database on the SD card, every 6th or 7th image that is loaded throws a NullPointer at:
imageCallback.imageLoaded((Bitmap) message.obj, wallpaperNumber);
I've checked everything and don't actually know what variable is actually null.

I'm trying to use NinePatchDrawables in a LayerDrawable, but for some reason I get a NullPointerException. I've isolated the problem to the getPadding() method; the following code reproduces the problem:
CODE:...............
What am I missing? Do I have to do anything special with the NinePatch? The program seems to work if I use the NinePatch directly (instead of putting it in a LayerDrawable).

I'm trying to change the content of a row in ListView programmatically. In one row there are 3 TextView and a ProgressBar. I want to animate the ProgressBar if the 'result' column of the current row is zero.
After reading some tutorials and docs, I came to the conclusion that LayoutInflater has to be used and getView() - overriden. Maybe I am wrong on this. code...

I'm getting this crazy error on multiple projects, even when I revert back to prior versions that compiled just fine. Unknown Error - java.lang.NullPointerException Android Packaging Problem Path is blank Location is Unknown. 1 - Project -> Clean -> All 2 - Deleting .metadata folder 3 - reimporting projects into the eclipse 4 - reverting my projects back to prior working versions using git.

I have a Service Receiver and a phone state listener class to determine the status of the phone. When the state is "CALL_STATE_RINGING", I call upon the method stopAllPlayback() in my main Activity. It is at this point that users report "Forced Close" messages. Can you help me determine where the problem might be? I'm new to Java so I'm not 100% sure how to troubleshoot based on a stack trace.
Here's the stack trace:...............

Im trying to display this listview, but I keep getting a: 07-17 21:14:22.233: ERROR/AndroidRuntime(349): java.lang.NullPointerException
I think I know what the problem is but I dont know how to fix it.
I have a String array which I will be using to be displayed in my list
CODE:.....
Dont worry the parser works great. the only problem I see with it is that the parser doesnt know how many strings the website will have so I am setting the String array in the parser to be very big: String substr[] = new String[250];
But I know that mostly there are only like 11 to 13 values that I will be storing in that array, the problem I think is when i do this:
CODE:..............
Since the String array is set to have up to 250 values in it and I only actually store say 12 then there are a null entries so when I run the code it shows me my list view, but when I get to the bottom of the view it force closes and the log tells me that there was nullpointer. I can tell how many entries I collected while I am parsing, but how do I tell my listview to only show say 12 items in the list so there wont be any null entries. or is there any other solution for my problem.
I tried doing what you said, but now I am getting a:
CODE:......
This is what I did:
CODE:.................

i am getting this error java.lang.NullPointerException at android.content.ContextWrapper.getPackageManager when am trying to get list of all installed applications on the device. Well let me explain what my program is doing. I have a server that starts when my application is started, and the client pings the server and asks to get a list of installed applications. The Server then asks the getPackageManager() and gets all the installed applications. But the getPackageManager returns the nullpointerexception. The Server is written in a java environment and is started from my android application. Could someone please tell me what am missing and why i am getting this error? hanks alot!!!Please find the code...

I am getting a NullPointerException at android.app.ActivityThread$PackageInfo$ServiceDispatcher.doConnected(ActivityThread.java:1012). My application is not even in the stack trace, so I have no idea what is going on. I am trying to connect to a service when it happens.

I've tried the Tab Layout example, and I've also fixed the few typos in the example (and added all the activities to the manifest). However, when I run it on the emulator I get a NullPointerException on the first line that says
tabHost.addTab(spec);
So my question, of course, is. What is wrong with the example that would cause this exception? I'm using Eclipse Galileo and set the target package as Android 1.5. So far I've had no other problems with the other examples on the android dev site.

I cannot for the life of me figure out why I'm getting a NullPointerException.
When a user clicks on a particular image, a dialog window is supposed to pop-up and display a larger version of said image:
CODE:..............
The associated onCreateDialog looks like this:
CODE:.........
For reference, this is cover_dialog.xml:
CODE:....................
Now, when the image previously described is clicked, the application immediately crashes and throws the following error through LogCat:
CODE:......................
The line in question refers to this line inside of onCreateDialog:
coverLarge.setImageBitmap(book.getCover());
I don't get why coverLarge is null at that point.
