Is it possible to force Android to use a given LCD density value? For example, if the app is running on a WVGA phone that reports LCD density of 160DPI *and* screen size of 3.7inch, one of those two values must be wrong. Is it possible to tell Android to ignore the 160DPI value and use 240DPI instead (for my Activity only)?

I read the official document about supporting multiple screens http://developer.android.com/guide/practices/screens_support.html
According to that document, I should just create different directories for different resolultion.
Now the question. How to support devices with normal screen and high density or low density?
I ask it because, there are two posibilities (WVGA800 (480x800) and WVGA854 (480x854)) and (WQVGA400 (240x400) and WQVGA432 (240x432)) and I don't know where to store some background images for them.
I would take drawable-normal-hdpi or drawable-normal-ldpi, but how to make difference between 480x800 and 480x854 or between 240x400 and 240x432?!
I've thought there might be a shell script I could run, maybe get an app that can run shell scripts from an icon on the home screen--but I don't know what that script would need to be, since it couldn't be about killing a process because that process ID is probably going to be different every time, and I don't know if it would require root. Rooting my phone is not an option.
I'm going to assume though that there's probably no answer to this and that I'll just have to keep going in by hand to force stop the app via prefs/apps/name-of-app/force stop. I just wish these app makers would have an exit option. Twitter and Vine and Growlr are examples of these programs with this kind of behavior. Facebook as well, but that'll just reload itself when you force quit it because it's a special "system app". I mean, I'm not expecting them to exit when I just go to the home screen, that would be silly, but I'd like SOME sort of option to close them besides going through the hassle of force stopping them via the OS preferences.
I want there to be NO chance whatsoever that these programs are going to access data in some way once I'm done using them. I have no problem with whatever the programs want to do when I WANT them running, but when I'm done using them, I want to be able to quit them, and it has nothing to do with wanting to have more free memory.
I'm experiencing an issue where Hangouts is force closing only when trying to communicate with one specific person. I can contact them fine when using the desktop interface, but when trying to use any form of mobile platform, whether that be phone or tablet, the app force closes. I've tried wiping the data, uninstalling and reinstalling.

2. How do I select a specific ring for mms. I know how to select sms, but I cant figure out how to change the mms.
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?

I'm wondering if it is possible to inflate a layout using a different density value than the default system density. I have a high density layout, which looks good on the Galaxy Tab (1024x600px, hdpi) and I like to use the same layout on another tablet with the same pixel resolution but medium density. The mdpi layout which is used works on the device but the screen just looks really empty and I would prefer to scale things up. So is there a xml argument for scaling the layout, maybe something similar to Bitmap.Options.targetDensity. Or could this be done with a new LayoutInflater class?

How to get the screen density programmatically in android?
I mean How to find the screen dpi of the current device?
Can you please tell me how can I specify dimension of layout for different density of screen?
i.e. the layout are the same across different densities, but some dimension are different.
how can I do that?
I'm getting ready to release my first application the marketplace. It's being written for devices running Android 1.5 and above, however there aren't any specific folders for the three different screen densities (I think those came around in 1.6). Should I make these folders myself? Where should I put image resources for the different densities and what should I put in my Manifest?
View 2 Replies View RelatedI'm being confused by the 'screen density' concept in Android. I knwe that dpi (dot per inch) came from the printing device. 160 dpi means 160 dots in every inch on the paper. However, when dpi is used for the screen density, for example, what's mentioned '160 dpi screen' in Android document, what's the meaning? 160 pixels on every inch of the display?
As described in http://code.google.com/intl/zh-CN/android/reference/available-resourc..., 1 dip (density-independent pixel) means 1 pixel on a 160 dpi screen. Why does the ratio of dp-to-pixel not necessarily change with the screen density in direct proportion?
When the dpi is changed from 160 to 80, how many pixels will 1dp will take? 0.5?
I can hardly understand why dip/dp is introduced into Android.
My project contains three drawable's folders: drawable-hdpi, drawable-mdpi and drawable. I build it with android:minSdkVersion="3". When it runs on Andriod 1.6 or higher it always uses images from drawable-mdpi on high density screens.
How to fix this?
I am trying to develop an application for which I want multiple screen support. I have read the Android article on Best practices for Multiple Screen Support. As per the article we have to follow 3 important things
1. Mention support for different screen sizes(large, medium and small) and any density in AndroidManifest.xml.
2. Place images of 3 dpi's (120, 160, 240) in 3 folders res/ldpi, res/mdpi and res/hdpi.
3. In layout's the dimension should be mentioned in "dip" units. Then Android will take care of the scaling on its own.
I have implemented all these points in my project. The images are picked up correctly from the appropriate folders. But the arrangements of the controls in not same.
e.g. I ran the app on three emulators
1. Resolution 240*320 dpi 120.
2. Resolution 240*320 dpi 160.
3. Resolution 240*320 dpi 240.
(All the emulator have same resolution but different density.)
The problem is the position of the controls is not same on all the three emulator. As per my understanding if the android:layout_marginLeft and android:layout_marginTop are mentioned in "dip" then this problem should not occur. As the density of the emulator increases the controls get placed more towards the right. Is it absolutely necessary that I provide layouts for all combination's of screen dimension and density even if the layout is same for all the devices?

I was working with Eclipse some minutes ago and I simply launched the emulator with a couple of AVDs that I created (QVGA, HVGA and WVGA screens). I've been doing thta for months, in order to check that every time I change something, the app looks fine for each type of phone.
The problem is that suddenly, the emulator in QVGA and WVGA start with huge icons on the desktop. They even overlap and the home of Android is corrupted. And when I run any application to test the emulator, the screen only shows a portion of the main View. It's like everything was zoomed in. I'm blocked because I can't use anymore the emulator. I'm going to remove completely Eclipse and re-install it, but I don't know if it will be enough.
in xml file we can define measuring units along with the values. If I want to set some property through code it only takes "int" value. What is the default unit for this int? px(pixels) or dp(density independent pixels) ?

View 1 Replies View RelatedWe can set the pixel values in custom views by multiplying them with
this.getResources().getDisplayMetrics().density;
This is ok when the screen aspect ratio is normal means not long
But how can we set the pixels along Y-axis when the aspect ration is long.

View 49 Replies View RelatedI'm running cm6 and the Galaxy S Theme. I would like to run my density at 160 because I really love how tiny the icons look on my screen. However, when I run the density to that setting my notification menu bar no longer stretches across the top of the screen, it appears as a small square in the left hand corner. I also have the same problem in the market place, where the grey background should stretch across behind where it says "market". My friend runs his at 160 and has no problems like this, however he is not running cm6 or the theme I am. So, while it doesn't really narrow it down any, I'm sure the problem is in one of the two, more likely the theme in my mind. Any idea's how I can fix or repair this problem?

View 3 Replies View RelatedHas everyone seen that you can change the LCD density on the Desire? (Well, on all Android handsets really). It simulates a higher resolution, fits more text on screen etc. There's an app on the market which does it, although it won't work on the Desire unless you're S-OFF. All you need to do is extract the build.prop file from /system to your PC (in recovery, use ADB PULL), and using a text editor change the value of LCD Density from original 240 to 200, then ADB push it back and reboot. I'm *really* pleased with the result. Combined with Launcher Pro I've a whole new feel to my phone...

1: open root explorer and go to /system
2: open the build prop and locate the line about half way down that says 'LCD density = 240.
3: change the value to 200 and save (it will automatically create a backup in case of a Rom issue)
4: reboot
I'm sure you can copy the build.prop file to your computer and edit and reinsert the file or use astro + god mode script on some Rom. Just be sure to make a backup as root explorer is the only one I know of that makes a backup automatically.You will notice the clock is smaller as well as a host of other great changes. I'm addicted to a smaller size but there are a few issues I've found.
A lot of hay is being made over the iPhone4's 326 ppi screen density. I was just curious, for comparison purposes, what's the pixel density of the Evo screen? This would be an easy calculation to do if I knew what the horizontal and vertical dimensions of the screen were, but I can't seem to find that information anywhere.
If anyone knows the pixel density or even just the exact X and Y dimensions of the screen..
What is the resolution for different density? Does it really matter or always keep 72 as a resolution?
When placing multiple assets do i need to use fill parent always or i can manually make a measurements for different layout?
