I know you can't take a screenshot without having root access, but is there a way to render an activity and all the contents to an image file?
anyone have code to do this? it would be nice to have any dialogs, menus, etc... as well, but not required.

I want to use a WebView to enable dynamic loading of ads in my app. I'm currently running on a HDPI device, and images width a width of 480px are clipped/scrolled. If I use images with a size of 320px, they are zoomed in and rendered at too low a resolution.The content of the loaded WebView url is a simple web page with just an image tag wrapped in a link, as well a simple head. I've tried playing with the viewport meta-tag, but without any luck.
View 2 Replies View RelatedI 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...

View 2 Replies View RelatedI figured out how to pass a String value between activites thanks to this site, however I'm having trouble passing an image. What I'm trying to to is have a user click a button that opens the gallery and allows selecting of a picture. Then I have another button that opens another activity that displays an ImageView. I want to be able to have that ImageView's image be the chosen one from the previous activity.
Here is the class that has the button I'm clicking to open the gallery and retrieve the chosen image: code...
What I'm not sure about is in the OnActivityResult if I should pass the selectedImage or the chosenimage in the b.putExtra("bitmap", selectedimage); line. I tried both but I didn't see an image on the second activity. Also I wasn't sure in the PreviewScreen class if I'm setting the imageview correctly. Any help is appreciated. Thanks.

View 1 Replies View RelatedI have been trying to create a ListView Activity with an ImageView in every row. I've used this tutorial: http://developer.android.com/resources/samples/ApiDemos/src/com/examp... The issue is that there are always some dividers missing whenever I run the example. The dividers are disappearing/appearing and flickering as i scroll the list (tested in emulator and HTC Tattoo). Strange is that the same example downloaded from the market (API Demos app) behaves correctly. Here is a screenshot of how it looks: http://yfrog.com/4cnokp.

View 1 Replies View RelatedMy goal is to develop a GUI application on top of a background image with buttons in specific places on the image. The first step is to display the background.
The image can be displayed with resources and is described in several FAQs including this one:
how-to-add-background-image-to-activity
It compiles and runs without errors, but the background is black. Here is the main.xml file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/rootRL" xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/background">
</RelativeLayout>
The image has been in png, 9.png, and jpg format with basenames of 'main' and 'background'. It builds but does not display. Making clean and recompiling does not help.
This behavior occurs on both the emulator and on hardware -- an Atmel AT91SAM9M10-G45-EK. The SDK version is 2.0.1.
I have two png image files that I would like my android app to combine programmatically into one png image file and am wondering if it is possible to do so? If so, what I would like to do is just overlay them on each other to create one file. The idea behind this is that I have a handful of png files, some with a portion of the image on the left with the rest transparent and the others with an image on the right and the rest transparent. And based on user input it will combine the two to make one file to display. (And I cant just display the two images side by side, they need to be one file). Is this possible to do programmatically in android and how so?

View 1 Replies View RelatedIn the app I am making, I would like to take a Base64 image that is received from a server, and save it to a file for displaying later. My question is where should I store this file? It needs to be dynamic, and may be empty when the program launches. I am unsure how exactly the file system on Android works, such as how file paths look.
Ideally I would like to be able to write the data to the image file using a FileOutputStream, and then display that image somehow.
I want to reduce the size of my image file to transfer it over the network. Do anybody know how can I reduce the file size using andriod APIs.
