General :: Allwinner A20 Tv Box - Change Screen Res / DPI / Aspect Ratio - System GUI Always Stops
Mar 23, 2014
I have an Allwinner A20 tv box, I trying to use it on a device with an old, low res, 4:3, 5" screen. It works but I have a few problems - firstly the box has "pal" and ntsc" settings for use with AV out, but when connected the picture is squashed inwards so circles are represented as ovals. I ve tried to mod the aspect ratio/resolution but nothing works, the picture is always distorted.
On top of that everything is too small for the screen, it is readable but things really need to appear bigger, so I also played about with the dpi, this does make things bigger and a better match for the screen, even though the device doesnt actually have a screen itself.
I ve done both these mods with several apps and modding the build prop and I always get "sorry systemGUI has stopped", constantly - when you close it, it opens again straight away. Clearly settings doesnt like these mods, so I m trying to work what I need to change so it DOES accept them.
How I can successfully mod the setting.db and get this working at the correct aspect ratio and a dpi that is suitable for use on a low res screen ?

I want to use my MK802 IIIS with a projector but I am having aspect ratio/resolution issues. Namely my projector supports 800x600 and 1024x768 but on my Android stick I get chose 1920x1080, 1280x720 or 720x480 (Settings->Display->HDMI modes). The stick has only HDMI output and I am using a cheap chinese adapter to connect it to the projectors vga input. For example with 720x480 I do get the picture but at left side a slice of it is cut off.
Ideal would be if I could set the video output to 1024x768 (with 4:3 aspect ratio).So, how could I change it?
Is there any Xorg like solution, that is, add resolutions by editing some conf file?I should create a custom ROM, build custom firmware...

In android, I defined an ImageView's layoutWidth to be 'fill_parent' (which takes up the full width of the phone). My question is if the Image i put to ImageView is bigger than the layoutWidth, android will scale it, right? But what about the height? when android scale it, will it keeps the aspect ratio? What I find out is, there is some 'white space' at the top/bottom of the ImageView when android scales an image which is bigger than the ImageView. Is that true? If yes, how can I eliminate that white spaces?

I'm wondering if anyone has figured out yet what the best resolution and/or aspect ratio is for custom contact photos? Most of my contact photos come from Facebook, but some I will edit on my PC and load onto the phone's SD card. I know there are issues with decent photos becoming low-res pixelated, so I'm wondering if I start with the best size and/or aspect ratio, maybe the phone won't have to resample the photos itself.

I'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.

I received a generic Chinese table. it worked well for about two-and-a-half months. Then, just recently, I discovered rooting and the wonderful things it allowed you to do. I decided to download a system-tweak app, which included a CPU control. I was a little wary of overclocking my CPU, having heard it may decrease its life expectancy, but finally I thought "What the heck?" and in a brilliant stroke of genius cranked my 1Ghz processor up to 1.5Ghz, and it promptly froze, forcing me to power it down. When I turned it back on, I discovered that it had been factory reset. I re-installed my apps, including the system-tweak app, and decided not to touch the CPU controls for a while. Soon after, while at my sister's talent show, I discovered I had about 30% battery life, and I was still supposed to record her. So I figured I'd underclock it to save the battery.
Unfortunately, as my finger touched the slider, my brother bumped my arm and caused me to lower the CPU frequency to its lowest setting. It became extremely sluggish, almost to the point of being unresponsive, and finally I had to shut it down. When I restarted it, it started to boot but then got stuck on the shimmering Android logo, and now that's all it does. I can't even boot into recovery mode, and unfortunately I had just turned off USB debugging that same day.

I have an Allwinner A10 clone (Kurio 7), it is designed for kids but otherwise a standard android tablet. After hours of googling I rooted and installed CWM & Gapps (not included in the stock ROM). So far so good. The stock ROM was causing issues with some apps, it needed to go.
I flashed CM10 and it worked but no touch screen. It needed a compatibility flash to make it work. You can guess what's coming. I picked the wrong one and now the device does the following:
Reboot loop
Black screen (backlight though)
PWR+Vol up no longer gets to recovery
Vibrates constantly between reboots (due to wrong patch I'm guessing)
ADB picks up the device for a split second between reboots but "adb reboot recovery" does nothing. Even when using wait command. Tried "fastboot flash recovery cwm.img" after wait command, no luck. Is there anything else I can try?

I tracked the behaviour of the different screen sizes when I increased the position of a graphic by 10 pixel. Unfortunately happened what I already thought. When the display is bigger, I'm able move a graphic a lot of times more to get to the bottom of the screen. So the ratio between the graphic and its environment is not correct anymore (so not 10 pixel as on normal screen) although the change of the graphic on the different screens looks correct (On big screen it is bigger, on small screens it is smaller). When I move the graphic from the top of the screen to the bottom, I can move that on 480x800 about 65 times, on 480x854 70 times, and on the 320x480 screen only about 25 times. So the target must be to calculate the right ratio so that 10 pixels on the small screen are 17 pixel (or sth. similar) on big screens. What approaches do I have to do that? I already thought about getting the value of res.getConfiguration().screenLayout to know if I have a small, normal, or big size to be able to calculate anyhow the right ratio, but this both seems to be pretty cumbersome and moreover I get values from res.getConfiguration().screenLayout I can't explain. I launched 6 emulator instances and got the following values from res.getConfiguration().screenLayout:
240x320 QVGA low density: 17 320x480 HVGA medium density: 18 480x854 WVGA high density: 34 480x800 WVGA high density: 34 240x400 WQVGA low density: 34 240x432 WQVGA low density: 266435490 (yes, I really get this value!)
This approach seems to be useless because I cannot even distinguish between 480x854 and 480x800, much less of the last value which seems to be corrupt.
How can I solve it to move a graphic on the different screens with the right ratio? How do game developers solve this when they support all screens?

(Galaxy note 2, Sungsonic ROM)
When streaming from Grooveshark in a web-browser, the audio-streaming stops (after finishing current song) when the screen shuts/locks. I have tried several browsers with the same result.
Audio-streaming from audio-specific apps (i.e. TuneIn) works just fine.
Someone mentioned somewhere that it has to do with the browsers not being set to over-ride the screen-lock.

I'm writing an app part of whose functionality is to record audio through the microphone. The recording seems to stop as soon as the screen times out and the phone enters what I think is sleep mode. I've noticed that some apps(Tokasiki's Voice Recorder, for one) don't seem to have this problem on this phone(Motorola Atrix) and continue to record audio long after the screen has faded to black. I've tried using a partial wake lock but it doesn't seem to maintain the recording. Should I use AudioRecord instead of MediaRecorder? Voice Recorder seems to get by without using AudioRecord.

When playing music with the stock Music Player application on my phone and turning the phone screen off or multitasking, the music is still able to play in the background. Is it possible to do the same with the stock YouTube app? I want to let the audio of the YouTube video I am watching to keep playing when I either exit out of the app or when I press the power button on my phone to turn off the screen to save battery. Although I can just set my phone screen to not go off when idle for a certain amount of time, but then again, that is battery consuming.
Phone information:
-Samsung Galaxy S Relay 4G from T-Mobile
-Ice Cream Sandwich 4.0.4
-Rooted
-No Custom Rom Installed

I've just upgrade my S2 from andriod 2.3ish to 4.1.2. Before doing so I changed the default system sound to that droplet sound (in the normal settings view, no root, nothing special with this phone) but now I've upgraded the 'normal' setting to change 'system sound' has gone. Have they really just scrapped that option?
