Google Play says my apk uses two Native Platforms ( my libraries) and so it supports 0 devices

烂漫一生 提交于 2019-12-01 05:42:14
问题 When i publish the .apk on Google Play it says: 0 devices supported. And on the bottom of the apk description it's written: Native Platforms: actionbarsherlock, SherlockNavigatorDrawer. These are the libraries i used for my project. They are not .jars, they are folders i put into the libs folder of the app. The problem is this: Google Play considers these two libraries as "Native Platforms" (I'm not sure what it exactly means or is), and this causes a filtering in the support of devices. I'm

Scanning for a Human Interface Device (HID) using C#

徘徊边缘 提交于 2019-12-01 05:27:30
I am developing a C# .NET 2.0 application wherein I need to scan for an attached HID. How can this be done? Because it is a HID, Windows does not assign a COM port to it. I only need to programmatically determine if the device is attached. Thank you. ADDITIONAL INFORMATION When I connect the USB device to my computer two entries appear under Human Interface Devices in the Device Manager. Clicking into their Properties yields this information in their respective Details tabs: HID-compliant device Device Instance Id: HID\VID_1795&PID_6004\7&2694D932&0&0000 USB Human Interface Device Device

How do I detect which iOS device my user is using?

北城以北 提交于 2019-12-01 03:59:02
I'm searching for a way to detect the device my app is running on. I am not interested in software version. I searched many questions but none of them (surprisingly) satisfy my needs for following reasons: Solution 1: NSString *deviceType = [UIDevice currentDevice].model; This does not work because it gives me just "iPad". I want to know whether it is iPad, iPad 2, new iPad, iPhone 3GS, iPhone4 etc. Solution 2: Not testing for device type, checking for individual capabilities This does not apply because I want this data to collect user statistics, not to perform any device specific operation.

Android Multiple Device Development

て烟熏妆下的殇ゞ 提交于 2019-12-01 03:15:03
问题 I am new to programming in general and have been teaching myself using Android SDK in Eclipse. Lately I have had a lot of iPhone developers telling me to ditch Android and go to iPhone because it is simply too hard to develop for the whole spectrum of Android devices. When I look at the dev guide, I see a page about developing for multiple screens, and it seems pretty straight forward. Has anyone had a hard time developing for multiple devices on the Android platform? 回答1: Developing for

java midi latency

问题 I´m trying to make a java application that is able to play notes on the computer after detecting a midi device. Once I get the desired midi device I´m seting the receiver to which the device´s transmitter will deliver MIDI messages. device.getTransmitter().setReceiver( new MyReceiver()) ; class MyReceiver looks like: public class MyReceiver implements Receiver { MidiChannel[] channels ; public MyReceiver (){ try { Synthesizer synthesizer = MidiSystem.getSynthesizer(); synthesizer.open();

Which /dev/… (devices) are the microphone and speaker in Mac OS X?

梦想的初衷 提交于 2019-12-01 02:13:45
问题 I have a MacBook Alluminium and I want to capture the microphone in a RAW format and output a RAW audio through the speakers, in a standard way, i.e., using the terminal with standard Unix commands and using the standard /dev/??? devices. So, the question/s: Which devices are the microphone and speakers? Those both should start with /dev/... Are they different if they are built-in or external? Which ones? (Also they have to start with /dev/...) If you know also the unix commands to print the

What is the path of photos album on iPhone device?

為{幸葍}努か 提交于 2019-12-01 01:35:46
I was trying to save a PNG file to photos albums folder on the iPhone device with a .png extension so that the transparency remains.. My question is: What is the path of photos album UIImageWriteToSavedPhotosAlbum function is using? I am using data write to file method.. Thanks You can't access assets on the file system directly (assuming this isn't a jailbreak question). In addition to UIImageWriteToSavedPhotosAlbum, the Assets Library Framework provides access to the photo library if you're targeting newer versions of iOS.

CUDA device to host copy very slow

I'm running windows 7 64 bits, cuda 4.2, visual studio 2010. First, I run some code on cuda, then download the data back to host. Then do some processing and move back to the device. Then I did the following copy from device to host, it runs very fast, like 1ms. clock_t start, end; count=1000000; thrust::host_vector <int> h_a(count); thrust::device_vector <int> d_b(count,0); int *d_bPtr = thrust::raw_pointer_cast(&d_b[0]); start=clock(); thrust::copy(d_b.begin(), d_b.end(), h_a.begin()); end=clock(); cout<<"Time Spent:"<<end-start<<endl; It takes ~1ms to finish. Then I ran some other code on
