I'm developing a coloring book app, how do I ensure that the black outlines of my drawing are not colored by the paint brush? I thought of decreasing the alpha value of the paint brush to show the black outlines when painting over them but upon painting the same area again, the black outlines will be painted over.

1) I want to ensure I am using a current 'fixed' location and not a previously stored one, so I am trying to avoid using getLastKnownLocation, but cannot seem to figure out the alternate to this?
2) What is the best way to display a "please wait" message or something along those lines while the GPS service is attempting to get a fix (and ideally periodically allow the user to cancel out)?

View 1 Replies View RelatedI have a service that will monitor location changes daily. What I know so far that to start a service at boot, I have to follow the linked tutorial. This way I can get the service started at boot, but to save battery I need it only between 9am-9pm.

How can I ensure a service is started at 9am and stopped 9pm every day?
Can someone explain what the different colored text means for each element? Should this be obvious? It seems to be more than an association with certain elements. Or even if just that, does it help you figure out new combinations, or just indicate what's already been combined?

View 2 Replies View RelatedMy application opens in Activity A1. None of the views in A1 are focused at startup, until I use the arrow keys to navigate through the views. A button press in A1 launches activity A2. When A2 opens, the first Button in A2 is focused by default. I do not want this happen. What I want is when A2 opens, none of the buttons are focused until arrow keys are used to naviagte through them(just like it is in A1).

View 3 Replies View RelatedI open an Activity which has a number of elements... some TextViews, some Buttons, and an EditText. For some reason, when the activity starts, the EditText is focused by default, which causes the keypad to appear hiding the screen. I only want this EditText to be in focus if the user clicks into it. How can I ensure that this View isn't in focus when the activity starts? I've tried calling requestFocus() on one of the buttons, but it hasn't changed anything. Ideally, I don't want anything in focus at all.
View 7 Replies View RelatedI am the developer of a heavily used application (over 110.000 active installs) and got one problem with the Android platform. One of the features in my application uses the normal way of the Android SDK to display a LED notification with a selectable color. The color can be set by ledARGB flag in http://developer.android.com/reference/android/app/Notification.html. This had been working with the emulator, the HTC G1 and the HTC Magic (myTouch) but now users starting to report that the HTC Hero does not show up different colors. (although the charging LED for the HTC Hero is orange and the normal notification color is green). The same thing occurs for setting a vibrate pattern. (flag -> vibrate in http://developer.android.com/reference/android/app/Notification.html) This does not work on the HTC Hero US. (it does work on the EU/GSM version of the Hero).....

View 1 Replies View Relatedi have a problem with double values i need to store in an android homed sqlite database. since these double values represent gps values (lat & lng), i really NEED an absolute precision down to the 9th number after the comma.when reading lng from this table into some (java) double variable, i get a value like "0.999956837" - this renders the values pretty useless to me.is there a way to enforce the precision i need other than storing the values as "text" fields (what would make expensive casts neccessary) or storing them as integers (meaning i need to multiply/divide at each write/read-op)?
View 2 Replies View Relatedi am using android.opengl.GLSurfaceView in my game, which is working well expect under one condition: Starting the game a second time after leaving it by pushing the home button, causes the game to flicker, because the rendering thread from the previous instance is still running and firing OpenGL commands. Now the question is, how can i ensure that only one instance of GLSurfaceView/GLSurfaceView.Renderer gets created?
To solve/workaround the problem i've tried to set the following properties in the manifest file to to ensure the activity gets shut down if it gets inactive.
android:configChanges="keyboardHidden|orientation"
android:launchMode="singleTask"
android:multiprocess="false"
android:noHistory="true">
But without success, the activity/rendering thread still keeps running. Do you know of any certain way to exit the rendering thread/free GLSurfaceView?
do I use the imageview as the skin of the colored listview or is there better ways to create them?

I'm new to Android and Java programming and I've manage to create a simple paint program, but how do I add a zoom feature? Right now I'm just extending the View class and using the "on Draw()" method. Do I have to use a Drawable to be able to add zooming functionality? I'm not really understanding the differences between the two. If I am way off base then please point me to a good tutorial on paint/zooming.
View 1 Replies View RelatedMy app uses a custom View that does a lot of text drawing.To ensure my text is always readable I've been using the result of calling getTextSize() on a newly-created Paint() instance as the minimum size. Docs say calling 'new Paint()' sets attributes like text size to default values.One of my European users just got a Motorola Milestone phone and reports that some text is unreadably small.I believe I've duplicated this using the WVGA854 skin in a 2.1 emulator.Run in that emulator my app's smallest TextViews look fine, but the text I'm drawing myself using Paint instances where I haven't changed the text size from the default is too small. I confirmed this by commenting out all setTextSize() calls in my View subclass: the text becomes too small to read comfortably.

View 4 Replies View RelatedTo explain i have a bitmap which is constructed as follows
Paint a rectangle color yellow I want now to paint a smaller circle over the top of the rectangle, but i want to use transparency. so that the circle results as a hole in the rectangle. {like swiss cheese with holes }
So if i painted the bitmap over a background the background would still be visible in the Circle/hole.
setting the drawcolor drawColor(Color.TRANSPARENT) just paints a transparent object. i.e. it doesn't erase the circle area of the rectangle.
How to do...?
One option is to set the circle color to say black and then look for an option to replace black with transparent within the bitmap.... but i can't find a solution for this either.
