App Inventor Image Sprite Move To Specific Coordinates?

Nov 8, 2011

I'm using App Inventor to develop a small game as Mole Bash.

The tutorial I'm following shows me how to make an Image Sprite appear on random locations given a certain amount of time.

I'd like to give the Image Sprite a list of 9 coordinates where he should position the image after the given amount of time in a random way.

So, I believe it should go something like this:

Procedure - Moveto - x1 OR x2 OR x3 AND y1 OR y2 OR y3

I can't seem to get the logic command OR on this procedure, since it will only let me give a min and max number for both x and y.

Android :: Mismatch Of Event Coordinates And View Coordinates

Jun 30, 2010

I've been trying to write a little application that recognizes custom events in Android: you hold your finger over a TextView for a certain length of time, and it changes color.I'm using the MotionEvent coordinates and checking if they are within the bounds of a particular TextView, which is within a table.I am just attaching the onTouch listener to the table within the activity.But I get weird errors: the coordinates seem to be off by one view (i.e. if I touch the view below the view above reacts); or sometimes one will react, and the other will not. Any idea what might be going on?

General :: Disable Specific App Permission For Specific Or All Apps

Mar 12, 2014

I have had androids for over two years now and am getting more and more concerned every time I download an app and seeing that it wants to READ my SMS message and Contacts.

Is there a way I can disable reading of SMS messages or any one of the other permissions by specific apps, or all apps?

Are we living in a world where any "joe schmo" can upload an app the to the app store and wait for those inadvertent downloads and collect all your personal information, and that's after all the time we spend protecting our identity and personal details?

Android :: Using Customized UI Components In XML

Oct 9, 2009

When I use customized components in XML, could I use a short name of component instead of a fully qualified class name? I wonder if some configuration file exists to do that work.

For example, my customized components is ex.object.RoundRect,

I should use it in xml file like this: <ex.object.RoundRect android:id="@+id/mainRoundRect01" ... />

But

I want to use it like this: <RoundRect android:id="@+id/mainRoundRect01" ... />

Is it possible? Is there a configuration file that can map the fully qualified class name to a short name?

Android :: Updates To Several Different Components In The SDK?

Dec 3, 2009

Earlier today, we released updates to several different components in the Android SDK. Xav announced these updates via the Android Developers blog: http://android-developers.blogspot.com/2009/12/android-sdk-updates.html. If you want to follow the blog via Twitter, you can now do so via [url]

In addition to the new tools and platforms, there's one other important change that I wanted to point out. We've added additional clarification to the docs about android:maxSdkVersion and what effects it might have on your app if you use it. You can see these details here: [url]

Android :: Sharable Custom UI Components

Aug 11, 2010

I want to develop and distribute some custom UI components for android apps. This custom component can do some network communicatioon too with my server. So by this I want to hide the communication protocol from my component users, and will show the content as provided by my control eg sponsor ads. This concept is same as Apple's iAD. Issue: 1. I want to hide my custom component code from its users so that they just need to include it in their antivity rest its upto me. 2. I have not implemented but sure that a UI component can do network communication.

Android :: Accelerometer Gravity Components

Jun 7, 2010

I know this question is definitely solved somewhere many times already, please enlighten me if you know of their existence,

Quick rundown:
I want to compute from a 3 axis accelerometer the gravity component on each of these 3 axes.
I have used 2 axes free body diagrams to work out the accelerometer's gravity component in the world X-Z, Y-Z and X-Y axes. But the solution seems slightly off, it's acceptable for extreme cases when only 1 accelerometer axis is exposed to gravity, but for a pitch and roll of both 45 degrees, the combined total magnitude is greater than gravity (obtained by Xa^2+Ya^2+Za^2=g^2; Xa, Ya and Za are accelerometer readings in its X, Y and Z axis).

More detail:
The device is a Nexus One, and have a magnetic field sensor for azimuth, pitch and roll in addition to the 3-axis accelerometer.In the world's axis (with Z in the same direction as gravity, and either X or Y points to the north pole, don't think this matters much?), I assumed my device has a pitch (P) on the Y-Z axis, and a roll (R) on the X-Z axis. With that I used simple trig to get:
Sin(R)=Ax/Gxz
Cos(R)=Az/Gxz
Tan(R)=Ax/Az
There is another set for pitch, P.Now I defined gravity to have 3 components in the world's axis, a Gxz that is measurable only in the X-Z axis, a Gyz for Y-Z, and a Gxy for X-Y axis.Gxz^2+Gyz^2+Gxy^2=2*G^2 the 2G is because gravity is effectively included twice in this definition. Oh and the X-Y axis produce something more exotic I'll explain if required later.From these equations I obtained a formula for Az, and removed the tan operations because I don't know how to handle tan90 calculations (it's infinity?).So my question is, anyone know whether I did this right/wrong or able to point me to the right direction?

Android :: OpenGL ES Missing Some Components?

Oct 1, 2009

I'm trying to run the "HelloTriangle" example, from The OpenGL ES 2.0 Programming Guide, in the Android emulator.I import egl.EGLConfig and opengles.GL10 from javax.microedition.khronos, but the ESContext type and definitions such as GL_COMPILE_STATUS and GL_FRAGMENT_SHADER can't be resolved.I reworked the triangle example somewhat for Android in that I'm using GLSurfaceView. I undertand that it is supposed to be used instead of OpenGLContext in the newer versions of the SDK.Am I using a "non-Android" approach to OpenGL ES? If so, what's the right one?

Android :: Add Views Dynamically Or On Top Of Other Components

Nov 19, 2010

I use a LinearLayout and first I have a MapView and below the map I have a TableLayout with informations fields.

Now I would like to add additional information fields (e.g. a new TableLayout) when the user select a specific menu item on the Options Menu. I would like to have these fields either between the MapView and the TableLayout, or on top of the bottom area of the MapView.

How can I add this TableLayout with additional information fields dynamically after the user has selected a menu item? How can I show it below the MapView or on top of the bottom area of the MapView?

Android :: Control Hierarchy In Custom Components

Oct 7, 2010

I'm reading the android docs on custom component development and i'm a little confused. If you're creating an activity, you can add add a hierarchy of views via setContent. however, if you're creating a custom component, you have to handle everything in the draw() overload.if i want to build a custom component that relies on a view hierarchy, is the model simply to create a hierarchy internally and then in draw call myViewHierarchy.Draw() or something?

The major challenge I face is aligning the components at desired positions. Please refer the three buttons(icons) and the way they are positioned.

Literally, going nuts, thinking how to position those exactly at the desired places.

Android :: Possible To Download SDK Components Without Using SDK Management Utility?

Feb 4, 2010

During the installation of my Android SDK, I am getting stuck during the process where the manager goes out and downloads all the revisions of the APIs and the SDKs.

It is potentially due to a socket issue that typically occurs when a database query is called and there are a large number of TCP connections... according to googling my error (No buffer space available (maximum connections reached?): recv failed )...

So I just need to know if there is a way, other then using the Android download manager, to download / update my computer with the following Android SDK components:

Android :: Understanding Custom Components And Multiple Resolutions

Dec 21, 2009

I had posted a similar thread a while back and received no feedback, so let me try to be more clear.I am able to use Androids components to build the most basic layouts, which include images, buttons, text areas, etc. These are like Android Lego! I can build the castle. BUT I want to design my own component, my own Lego, that draws on the screen and uses the available area that the Android components have not used. ie, I want to have a top layer of buttons, and the rest of the screen, whatever it is, I want to use to draw 2d graphics. So, I want to make my own Lego, and use it with the other Android Lego. However, I'm also trying to be a good developer and making this for whatever resolution is thrown my way. What is the best way to do this considering the deluge of different resolutions Android developers must cope with? Is there a way to do a table view and return the remaining screen size? Or, am I stuck making an entire new box of Lego here?

Android :: Which Components Does Call State Ringing Block?

Apr 20, 2009

I am writing a service which listens an incoming call. I have a function but it behaves differently under these cases when i call the function in case case Telephony Manager . CALL _STATE_OFFHOOK: it works! when I call the same function in case case Telephony Manager. CALL _STATE_RINGING: it doesnt work. it seems that when an incoming call happens the system blocks some components. what should I do to prevent from this situation. Should I move my calculation to a background thread? Does it work in that way?

Android :: Using External Source Inside Program (Eliminating Swing Components)

Dec 5, 2009

I am having a little trouble using some external source files. I am new to eclipse and the methods used to import external source files. Basically this is what I have done. Downloaded the source files for a java project called "TrueLicense" via CVS. Imported this library by going to "Projects" and adding the "TrueLicense" project (I am not sure if I should do this in "Source", "projects" or "Libraries"?) Imported the required classes into my android project without any compile errors.

When I run the program I get:
12-05 15:52:28.632: WARN/dalvikvm(724): VFY: unable to find class referenced in signature (Ljavax/swing/filechooser/FileFilter;)
Then a whole lot of other errors. This seems sensible as there is a sections of the TrueLicense package that used Swing. How do I only import the parts of TrueLicense that I need?
