If got a String and I want to convert it into a Bitmap.
View 1 Replies View RelatedI have a problem in converting base64 string to bitmap in android. I am using the camera to fetch the image and i am convert the image to base64 string to post to the server. I want to show that image in the imageview so how can i show the image in the ImageView after fetching the image from the camera.
View 1 Replies View RelatedI have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?
I am 1) taking a picture and 2) then draw another Bitmap on top of it 3) then I store it
I am doing it as follows and it works on the emulator.
On the device I get a OutOfMemoryError: bitmap size exceeds VM budget android.graphics.Bitmap.nativeCopy(Native Method) android.graphics.Bitmap.copy(Bitmap.java:199) in the line copy the Bitmap to get a mutable Bitmap.
CODE:...........
What I am asking:
a) Is there a better way to do what I am doing? 1) take a picture 2) draw another Bitmap on top of it 3) then I store it
b) What is the best way to create a mutable Bitmap from the picture I just took with the camera?
In my app, resolution is not an issue. If it works better for small photos that would be fine.
I have the localized strings file that is used in the Iphone app that I work on to port to Android. Are there any tools that go through the file taken from the xcode project and build the xml needed to use the strings in android? This tool should be easy to build but I appreciate any pointers to already working tools.
View 4 Replies View RelatedIn Android, capturing date from datepicker and storing as string in sqlite. Sorting by date doesn't work because they're strings (unless I'm doing it wrong.I've googled this issue for ~5 days, and it looks like there should be a way to capture the date from the date picker, convert it to a Long, store it in sqlite as a Long, select and sort on the Long date value, then convert the Long back to a "mm/dd/yyyy" string for display. I've tried various combinations of parse statements, Date, FormatDate, etc. with no luck at all.On activity start, get today's date and display it in button which calls the datepicker.Capture new date from datepicker (if one is entered), save it as a long to sqlite.On opening an activity showing a listview of records, select from sqlite with orderby on date (Long), convert Long to "mm/dd/yyyy" string for display in ListView.

View 5 Replies View RelatedI have two questions actually:
Is it better to draw an image on a bitmap or create a bitmap as resource and then draw it over a bitmap? Performance wise... which one is better?
If I want to draw something transparent over a bitmap, how would I go about doing it?
If I want to overlay one transparent bitmap over another, how would I do it?
My goal is the draw a bitmap onto another bitmap but rotated 90 degress. whats the most efficient way to do that. My current method is as follows which is horribly bad because it creates a new bitmap every time.

I have preferences where you can enable/disable what items will show up on the menu. There are 17 items. I made a string array in values/arrays.xml with titles for each of these 17 items.
I have preferences.xml which has the layout for my preferences file, and I would like to reference a single item from the string array to use as the title.
In the Android developer reference, I see how I can reference a single string with XML, but now how I can reference a string from an array resource in XML.
Can anybody give me some clue that how to convert binary string into a string(english). I have tried and googled so much but couldn't find an answer.
View 1 Replies View RelatedI have a class that creates a view to gather data via a function getView() that provides a view with an EditText.This class has also has variable answer.When the user chances the EditText I want to store the content of the EditText in answer.If I would use an onKeyListener I fear that the answer will probably get stored before the last letter is entered.Is there a good way to handle this in the getView() function via some other listener?

View 3 Replies View RelatedDoes anyone have any idea how to find the n-th field (string) in a delimited string where the delimiters (separator) could be either a single char or several chars.and the syntax for user-defined function is FindNthField(string,separator,position)so position 3 would return three,The separator in use would actually be Chr(13).This has to run on Android and so should be efficient.

I'm currently developing my own Android widgets. To help me in future projects and speed up my developments, I've been trying to create a private jar that contains all those widgets (that extend from Android classes such as View or ViewGroup). To do that, I created a project and included all files (.Java and resources) in this project. I exported this as a jar file. To test this jar file I created a new project and tried to include my widgets using an XML layout. Unfortunately, it seems that the system does not "see" my resources. Looking at the Android source code, I noticed that android.jar contains its own resources so I assume this is possible.
I'm sure I've done something wrong...but what? What is the problem? And how to solve it?

View 4 Replies View RelatedMost of my work phone calls are unknown number and lately I kept getting a phone call from a private number every half hour or so and it only ring once then hang up.

View 7 Replies View RelatedI've integrated lots of private information like accounting, messaging, emails, tasks and so on, into desktop widgets and everywhere around the phone. Every so often, someone wants to take a look at the phone and play around. Reading some important stuff is one thing, but people tend to mess the stuff around as well. Have you found a program or a way to protect from that? (other than denying to the people :> ) I guess some kind of shell program that you turn over when someone wants to demo the phone would be a nice solution.
View 7 Replies View RelatediFMW was upgraded: Mobile site for public person or private file share for secret person in one app.
It has two inversion functions on one app.
Public person can get his/her own public web site on the phone and secret person can use only private file sharing directly on the phone without uploading.
Those who want two demands above will use whole functions.
What will you choose of those choices?

View 6 Replies View RelatedI am developing an application that involves some sensitive user information. I retrieve this information via a private web API. I am trying to determine the best way to get this data into my app. Right now I'm exploring creating a content provider that can do so; my hesitation is in making it secure. I want this data to be usable only by my application. Ideally, no other apps would even know it exists.
Do you have any pointers or advice on how to do this effectively and securely? Any info on content providers who's data source is a remote OAuth'd API?
I say content provider, but if that isn't the best way to do what I need, by all means let me know what else to look into.
I just want to read <string-array> resource elements into a String array. I don't want to make a view or anything and mess with adapters - just want to transfer the elements. Is there a built in class for this? Or do I need to treat the resource file as a regular file?
