Button showmapButton = (Button)findViewById(R.id.showmap);showmapButton.setOnClickListener(new View. OnClick Listener() {public void onClick(View v) {Intent intent = new Intent(HomePage.this, ShowMap.class); intent. putExtra("username", value);startActivity(intent);In my main menu i have a button 'ShowMap' Everytime i click on showmap my map will hit a null pointer exception causing the program to crash. ShowMap' works fine if i launch straight to that page without having a need to click button to call that activity.I tried changing all my files to "extends MapActivity" instead of regular activitiy but the program will still crash whenever i click on show map

I have an application that works fine with smaller images (say 1024x768 or so) but when you rotate the phone into a different orientation (say landscape to portrait) mode with a larger image on the screen, and then call ImageView.setImageUri() it goes into the BitmapFactory.class and never returns.So the app eventually times out. Never throws an exception, just never returns. Has anyone else seen this? Sounds like a bug in the Android code more than something I am doing since it works fine for smaller images.

I am very new to Android (and Java) originally a C# developer.. and am struggling with the concepts and terminology.
I have been through almost all the tutorials and have decided to start on my first test app.The first part of my app is going to involve using the gallery widget (based on the hello gallery tutorial) to display a load of images. (these images will eventually come from the phones camera, but I will cross that bridge later!) My images are currently stored in the drawable folder in my project.As a first step I want to just have the user click on an image and it pops up full screen, just so I know how to get reference to it, but I am struggling. Evetually I want the user to click an image, then a window/activity(?) will open asking them for a bit of text. This will then be store in sqllite against the image. Code...

I am working on my own app. It appears that when I switch to other tasks after opening and navigating through my app, and switch back to my app later, it crashes. When not task switching, it seems perfectly stable, but task switching tends to make this crash. This does not always happen. If I only quickly switch to email and back, it works perfectly, but if I run several games, and then switch back, the problem occurs. I guess it is something in Android's memory manager that my app doesn't work properly with, but I can't figure out what exactly the problem is.This is my log:

I have an Android application that allows the user to select a photo that has already been taken. Once the user selects a photo, I grab the URI information for that photo, use that information to create a bitmap, and then I set the bitmap in an ImageView. This all works perfectly fine.I then give the user the option to select the picture for viewing. When the user chooses to view the picture, I launch an ACTION_VIEW intent, passing the URI data. Intent intent = new Intent(Intent.ACTION_VIEW, pictureUri);startActivity(intent);As you can see, this is very simple code, nothing special going on. The problem is that, when I run this code on my Droid running Android 2.1, about 6 or 7 times out of 10, the application will display the correct picture. But the other 3 or 4 times, I get shown the wrong picture. Also, each time the wrong picture is shown, its always the same incorrect picture being shown. The fact that I see the right picture the majority of the time leads me to believe everything I'm doing in code is fine, so can anyone tell me if you have seen this problem before, and better yet, is there a solution? Here is the exact sequence that I observe on my Droid when I run this (Note: Image URI is already saved before I start the Activity):
- I choose "View Photo" in the Activity
- When things work, I get taken to the gallery and shown image 74
- Each time things do not work, I get shown image 82
Keep in mind that when I start the Activity with the URI already saved (retrieved from database), I set an ImageView based on the URI data in onCreate(), and the Image being shown in the ImageView is ALWAYS the correct image. It's not until I actually decide to view the image using ACTION_VIEW that I see odd behavior. And I know it's not something specific about these 2 photos. I observed this behavior using other photos in the past, and got the same behavior.

I have an app that displays a video using VideoView. The layout consists of a Clock and a VideoView laid out in a simple vertical LinearLayout. Here's my code snippet that I use:
VideoView mVideoView = new VideoView(this);
mVideoView.setVideoPath(myVideoURL);
mVideoView.requestFocus();
mVideoView.start();
Since the buffering of the video takes about 8-10 seconds, the layout comes up with the Clock, but the VideoView stays blank. What I want to achieve is this:
- Display an ImageView for the 10s while the video is buffering
- Detect when the video is ready to be played (onPrepared?)
- Show the Clock and VideoView and start the Video

My app shows a list of items, where each line is an item title with its image asides, the line reserves 70% of space for text and 30% for image. Imagine what iphone app store looks like. Which view/layout combo is recommended for this purpose? I googled and find this article

In all of the screen shots showing off Google Now, there is always an image of a card showing meeting with someone at a particular location, the time it takes to arrive at that location, and a map of the meeting location. I have not been able to figure out how to get Google now to do this.
Presumably, that is a function that arises from a Google Calendar appointment. I've created meeting appointments and used specific addresses for the meeting location, but when Google Now displays that appointment, it displays the name of the meeting and the address only - no travel time and no map. In contrast, for places that I visit regularly, Google Now does display a map and travel time to those locations. But those are not regular appointments.

I believe this is pretty trivial but I can't get it to work. I want to display a default image in gallery elements (ImageViews) while their actual image is being fetched from the net. Right now, nothing is shown for an ImageView which its image has yet to arrive. Once it arrives it is immediately shown. What I tried is right after the instantiation of the ImageView to call its setImageResource function like so:
final ImageView i = new ImageView(mContext);
i.setImageResource(R.drawable.loading);
But it doesn't seem to work. Below is the full getView() function.
public View getView(int position, View convertView, ViewGroup parent) {
final ImageView i = new ImageView(mContext);
i.setImageResource(R.drawable.loading);
// if the drawbale is in the buffer - fetch it from there
Drawable bufferedImage = DataManager.getInstance().getImagesBuffer()[position];
if (bufferedImage != null){ i.setImageDrawable(bufferedImage);
BitmapDrawable drawable = (BitmapDrawable) i.getDrawable();
drawable.setAntiAlias(true);
} // if drawable is not in buffer - fetch it from the net via AsyncImageLoader
else { String imageUrl = DataManager.getInstance().getImageBufferInstance().getImageUrl(position);
Drawable downloadedImage = AsyncImageLoader.getInstance().loadDrawable(imageUrl, new ImageCallback() {
public void imageLoaded(Drawable imageDrawable, String imageUrl) {
if (imageDrawable == null) { imageDrawable = getResources().getDrawable(R.drawable.icon);
} i.setImageDrawable(imageDrawable); BitmapDrawable drawable = (BitmapDrawable) i.getDrawable();
drawable.setAntiAlias(true);
} } ); i.setImageDrawable(downloadedImage);
} i.setLayoutParams(new CoverFlow.LayoutParams(Utils.getInstance().getScreenWidth() / 2, Utils.getInstance().getScreenHeight() / 2));
i.setScaleType(ImageView.ScaleType.CENTER_INSIDE); return i;
