Android : Show Pictures In WebView That Aren't In Filesystem
Aug 31, 2010
How can I show pictures in WebView without saving images into file system?
I have tried to implement my custom Content Provider, but method openFile returns ParcelFileDescriptor that points into filesystem (or socket). My pictures are in filesystem, but in encrypted form.
I have tried also URL.setURLStreamHandlerFactory, but in android java it is useless (because custom streamHandler can be register in jvm that is not allowed). I also try html code "img src="data:image.gif;base64,R0lGODlhiAAkAMQAANOOk...", but in embedded chrome it's not working.

I am new on android and building an application which uses webservice to collect user information in XML. I also get path for a small jpeg picture of each user. (Currently there are about 200 users) I am parsing the XML and storing the information in SQLiteDatabase. Pictures are stored as blob and able to retrieve them.
I display names of users on listview with images as well. But is this a good solution for storing pictures in SQLite Database ? or should consider storing it in file system ? Which is suitable in terms of performance , as well as memory and any other pro and cons on Android.
Also like to know which is best performing XML parser for Android ?
My purpose is only to parse xml files which I get through web services and sort out the data to store in storage. And lastly my memory goes off easily when I load all images to display in list view after making thumbnails of each (which is obvious).
Was wondering is there any library/framework/app available which dynamically loads images as and when required (when that list item is on display) something like Gallery program ?

Was wondering why some apps that don't need to open to update there info like weather bug, show up in Advanced task kill running? Like an alarm clock or spare parts app.Or why does weather bug show up even inside the 6 hour time frame I set up for it to update.Also wondering If I use the weather bug short cut on my home screen and not the WB widget will that stop it from ever opening/updating unless I open it by tapping the short cut icon.

I have a little question, perhaps it's quite easy, but I've been looking for it for over a week now.
When I search on the market for a specific application, say "shazam", I get a message;
Suggestion
- Make sure all words are spelled correctly
- Try other keywords
- Try less specific keywords
However in the top bar it says
"1 result for Shazam"
But the result isn't showed. I have this problem with up to 9 search results.
I'm using a HTC Hero. Any suggestions on this one?

I am using a TabWidget that contains a List in one tab. What I want to do is when a user selects an item, a webview is shown in that tab.
If the user then wants to go back to the list, they would click on the list tab.
I can get the webview up that replaces the whole tabwidget but don't know how to leave the tabs and show a webview.

I am using the webview control in android to show the html content. But I face a problem that in webview I have to fix the height so thats why if html content contains less data then it wasted the space. Is there any solution to solve this problem that how can I show only same content as html has in the webview without any wasted space please help. following xml i used to draw webview is this right? In this i give fix height to webview. if i am not giving fix height then it will show only 1 line data with scroll.

I declared a WebView activity in the manifest like this. code...
When I start this activity within my main activity, only the title of the dialog, containing the apps name, is visible but not the WebView. If I add a TextView to the LinearLayout, it is shown as well, but still the WebView is missing.
If I don't apply android:theme="@android:style/Theme.Dialog" in the manifest, the WebView is displayed.
Why is that and how can I show a WebView in a dialog?

I am having issue while showing a WebView in an activity in the middle of the screen. I have an activity and I want to show a webview in the center of screen. My activity is transparent so background activity will be visible. Whenever I try to create a webview and add it to activity using setContentView(webview) it always shows the view on the top left corner of the screen. Is their a way to workaround this?I am trying to do this via pure code only.
Here is my code.

Is there a way to show that a WebView item contained as a item in a ListView is selected? Right now the WebView does not seem to display its contents transparently like every other control so it takes up the entire view and does not show its state as selected.
Also, when the content of the WebView is selected, scrolling down with the track back does not seem to cause the WebView to loose focus. If I continue to scroll down with the track ball, all of a sudden an item in the middle of the ListView gets selected.

I have encountered a problem with focused text fields in a WebView not showing entered text values.As long as a WebView text field has focus it will not show text or even the blinking cursor.You can select and highlight the text or unfocus the field to see it, but when it gains focus it will not show the text as if the foreground color of the text is white.The simplest code to demonstrate this is below.With the setTheme using a Light background, try typing values into the Email text field to notice that the text is not visible when the field is focused.

I just installed Handcent on my Droid and am having two problems. I checked the settings and can't figure out why these things aren't working properly.
1. The pictures from my contact list do not show up next to the texts. Every one of my contacts has a silhouette and question mark in place of the picture - which shows up fine in the default messaging app.
2. When a new text comes in, the new text notification pops up on the taskbar. I do not receive a handcent notification icon, and if I open the text with Handcent, the default message notification does not disappear.

I guess this question has been asked before, but I can't seem to find a proper answer/solution. Have a note-taking app, which allows to take pictures. For that I start an intent, that starts up the built-in camera-app. So far so good. But when I show that image in my app, it's in a much smaller format The funny/weird thing is, that the camera-app did take a full-resolution picture! But for some reason I can't get the full version to show in my app? So, when I use the standard Android Gallery app, and go to that picture, it is very obvious that it's full size (I can zoom in and see details I really can't see when I zoom in, in my own app). Also, the dimensions are really those of the original picture, taken with the 5MP camera. In my app, they are very small. My phone has Android 2.2, but the same happens on my emulator (Android 2.1). How should I retrieve the pictures in my app? Tried a couple of ways, but none works :( Don't need a complete example (allthough that's very welcome), just a few clues are enough to search for myself.
