问题 I am currently working on an android application where I have to log all the sensor values. I got the sensor event timestamp from "event.timestamp" and I converted this value into a unix timestamp. long currTimeRelativeToBootMs = SystemClock.uptimeMillis(); long currTimeAbsoluteMs = System.currentTimeMillis(); mStartTimeAbsoluteS = ((double)(currTimeAbsoluteMs - currTimeRelativeToBootMs))/(double)1000.0; ... //timestampRelativeInNs = event.timestamp double temp = mStartTimeAbsoluteS+((double

问题 I'm having an issue comparing font sizes between pages on my layout. I have the font set on the body with font-size: 100%; and on my paragraph tags with font-size: 1em; . I have a two column page set with CSS columns and a single column layout. The font is rendering larger on the single column page. It's also rendering differently with font-size: .75em; in the footer and on a main section of my site. I've determined that it's Chrome only and appearing to cause the issue on the Nexus 7. The

问题 I'm trying to handle layout for different screen but I found it hard because emulators always use default layout. I cannot understand why. I create a Nexus 7 emulator and I expected to use layout-sw600dp. The same with Nexus 10 emulator. How came?! Thanks in advance R. 回答1: There are 2 versions of the nexus 7 that you can choose from. There's the newer model and the 2012 version. Choose the 2012 version and it should work as expected. 回答2: Check your layout directories once again, you might

问题 I am having trouble running an app I am developing in Android Studio on my Nexus 7. I have successfully gotten this to work before using the same tablet and computer (running Windows 8), but since having my laptop repaired and everything wiped I'm convinced something with my dev environment is messed up. When I go to run the project, there are no available devices, so it is not recognizing my Nexus 7 anymore. Things I have tried making sure my computer recognizes the device and that I have

问题 I'm having a very difficult problem creating a shader program on android. when I call glCreateShader or glCreateProgram each always returns 0. I've covered all my bases with regards to troubleshooting: I checked to make sure I had an ogl context (I do, i tested this by clearing the frame buffer with various colors, which worked). I tried glGetError but it returned nothing (GL_NO_ERROR) I'm not an opengl or android expert so I don't know of any thing else that could be causing this. I've been

问题 I'm developing an application for tablet 7 inch Kindle Fire HD and Nexus 7 . These two applications are the same size and the same screen resolution. However, I run my application, it is very different. Why? it seems this is because the nexus 7 is detected as TVDPI, and the Kindle Fire HD is HDPI. How to have a same rendering based on a model 1280 * 800? Thank you 回答1: Well, it seems you've already discovered why the two have differences, it's because they report different density scale

问题 I am building an app that will form part of an exhibition. It will be displayed on a Nexus 7 which will be securely mounted. The app has touchscreen functionality and will display interactive content. I need to be able to disable as many features as possible whilst on display as I do not want the public to be able to get to anything other than the app. The main thing I am struggling with is the back/home/recent app list button. I have found some examples of disabling home button (child lock
