This works great for files.I marked the location needing refactoring to get it to work with a bitmap. I can't seem to find a compatible ContentBody for .addPart.The problem I am trying to solve is that I already have the image in an ImageView within an Activity, so rather than read it again from the SD cara, I want to pass it to this method directly.I will probably scale it while I am at it.
View 1 Replies View RelatedI want to call a bitmap from a method in my main class and am unsure how to do it - I have a method: Code...
So basically, how can I place the bitmap in my detectFaces method in my main class and pass it as a bitmap on my imageview in my false class?
I 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 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.

What's a suitable html parser for Android?
View 2 Replies View RelatedWe're seeking advice for our application in the Android Market, in relation to nominating a suitable minimum SDK version for the APK files published through the market. We understand that at this juncture there's no facility to provide associate multiple APK files (supporting different minimum SDK versions) within a single listing in the Market.
We have updated our existing application with new Android 1.6 API features and are keen to release it to the Market. However we're concerned about the general availability (and uptake) of version 1.6 firmware and seeking to ensure that we don't inadvertently release an updated APK should there be limited release of this firmware.
Can anyone provide an indication as to how widely the 1.6 firmware has been released? To that end, what are generally acceptable practices for supporting multiple SDK versions from within the market?
I need to know how to decide which package is best suitable for testing my app. Some info is provided in this link..
View 3 Replies View RelatedWhat I need is to perform some network operations in background inside a service. I want them to run in a service because, as pointed out in the "developing rest client application" talk from google io, I don't want to loose the result if the activity is brought in background. What sounds quite obvious is to use an Intent Service, and get the result as a broadcast. In this way I am sure the service will die and no consume any other resources when its done, but I need to convert the actions I want to perform to intents and back. Well, I was now wondering if it makes sense to bind to the service instead, at least for getting the result. And a more general question: is the bind mechanism suitable for one shot services, or it just make sense for persistent services? What happens if I call the startService method but the service is already active? Will it start another service, or will it call the onStartCommand of the same service? I am asking this because if I use "regular" non sticky service, it could happen that I need it to perform some action and I don't know if it is already active (and I don't want to have a queue of action waiting for onServiceConnected to be called.
View 7 Replies View RelatedI can see that I'm going to have to get an actual phone sooner than later, and for various reasons I'll need to get an "unlocked" version. As long as I'm laying out that many $$$, I might as well get one that I can use personally and shop some apps, etc.So would the Samsung Galaxy S be suitable for development work? I assume that a general unlocked version would have all the expected Android built-in apps and would not have restrictions on what apps can be installed and from what sources. Any comments on this device?(This also assumes that I can actually get one. The effects of that chip shortage that they've been talking about seems to be hitting the supply lines already.)

I'm trying to override the onBackPressed() method of the ActivityGroup class:

but I'm getting the error The method onBackPressed() of type MyClass must override a superclass method. I'm relatively new to Java, I've seen here that people do it and it works for them Why I'm getting this error? I'm writing an app for android 1.5, could the problem be here?
In Eclipse, when I mouse hover over a built-in method, it displays a method definition including stuff like what the method does, input objects, return objects etc. If I have a yellow line (warning) under the method I'm trying to use, I can't get the mouse-over to show the definition. If I try hitting F3, I get a "The Jar of this class file belongs to container "Android 1.6" How do I show the definition of the method I am using when there is a warning?

View 1 Replies View RelatedI'm looking to buy a slightly bigger card for my hero, especially since apps2sd has stolen some of the space on my card now. This is the card I was thinking of going with, Play.com (UK) - Mobile - Free Delivery But since I've never purchased anything like this before, just wanted to check this is the right thing. It's listed as 'Micro SDHC Plus', but I take it that's just marketing spiel for plain old Micro SD rather than a different type of card?
View 19 Replies View RelatedI currently have an official orange HTC Hero running on official 2.1. No problems, I actually like it a lot but browsing this sections of the forums, I've seen that people have taken advantage of rooting so. Are there any ROMs that you would pick over the official 2.1 that don't:
Eat battery life
Cause glitches(that are very noticeable)
And can:
be updated to directly from official 2.1
If you have any guides or info or links that are in English, I'd appreciate it if you could show them to me. But the most important thing is whether it's worth it.

View 4 Replies View RelatedI'm not real savvy about the power situation for the Sprint Hero that I just bought. The OEM power source says that the input is standard 100-240V. The OEM output shows as 5V=1A. Now, I have other USB chargers (e.g., for my iPod). The input is the same (100-240V), but the output is:
Output: 5.0V=400mA. Can anyone tell me (a) whether this will HARM my Hero, and (b) whether this will effectively CHARGE my Hero? Also Connecting to my computer via the USB cable: does the charge take longer than if connected directly to a wall charger?
i have a Samsung galaxy s3 clone . it was bought from shop in china . dont know who actually made it .
i made its backup with mtkdroid root tools 2.3 but its corrupted.
i tried few roms and flashed it with wrong preloader and dsp_bl .. which gave me total brick .. no charging . no display. no detection by pc. after a lot of hit and trial i somehow unbricked it . now it has android 4.0.4 . but it has few problems.
1: Cameras are not working
2: Sim management is greyed out /disabled .. and no imei ..
3: No baseband ..
now since my own created backup is corrupt and this set is not branded so no real way of identifying it how can i find its factory rom ? from which information I can decide whether a ROM is compatible with my device?
all the details along with pics of my set are here ..
These were taken with stock ROM ..

Whilst trying to update through the Android AVD Manager, I receive the message:
"No suitable XML Schema Validator could be found in your Java environment"
It therefore can't parse the repository.xml and I can't download any updates.
How can I get rid of this error? I am guessing it might be caused by GIJ being the default Java implementation on my platform (Debian), however I have also installed the Sun JRE/JDK now.
I am creating an Android app that includes a third party jar. That third party jar utilizes internal logging that is failing to initialize when I run the app, with this error: "org.apache.commons.logging.LogConfigurationException: No suitable Log implementation".
The 3rd party jar appears to be using org.apache.commons.logging and to depend on log4j, specifically log4j-1.2.14.jar. I have packaged the log4j jar into the Android app. The third party jar was packaged with a log4j.xml configuration file, which I have tried packaging into the app as an XML resource (and also as a raw resource).
The "No suitable Log implementation" error message is not very descriptive, and I have no immediate familiarity with Java logging. So I am looking for likely causes of the problem (what class or configuration resources might I be missing?) or for some debugging technique that will result in a different error message that is more explicit about the problem. I do not have access to source code for the 3rd party jar.
Here is the exception stack trace. When I run the app, I get the following exception as soon as one of the third party jar classes attempts to initialize its internal logging. code...
