adk

问题 I wonder if there is any native support for andengine or ADK to ask question-toasts? For example if I press the back button, I want some box to popup asking if I really want to quit the application and give me the option to answer yes or no. 回答1: Better to use alert dialog use this code, hope work same like that @Override public boolean onKeyDown(int keyCode, KeyEvent event) { // TODO Auto-generated method stub switch(keyCode) { case KeyEvent.KEYCODE_BACK: AlertDialog.Builder ab = new

问题 Am trying to understand how the Android Open Accessory API works with the Arduino ADK board, I've been able send and receive information but I just want to know how everything works. I got to this function description: int AndroidAccessory::read(void *buff, int len, unsigned int nakLimit) { return usb.newInTransfer(1, in, len, (char *)buff, nakLimit); } From some googling I figured that NAK is some code that gets sent if something went wrong during the handshake, so is NAK limit the number of

问题 I'm programming android adk program (http://developer.android.com/guide/topics/usb/adk.html) on Samsung galaxy tab 10.1 (version 3.2). I have managed to get it working on simulator by using Google API level 12, but not on actual device. Here is my DemoKit program. When I run it on galaxy tab, "force to close" error and I have some error on LogCat during downloading and installing DemoKit.apk. I do not know about LogCat so I have attached LogCat file as reference to detect error. (LogCat file

问题 I have a library-only Android eclipse project (no main class, only library classes) that I want to include in my main Android Application project. I went to the Build Path and added the library project to the "Required projects on the build path" on the Projects tab, and checked it on the "Order and Export" tab. However, when the application is run, it emits VerifyError exception, because the class from the library project didn't happen to be packaged together in the apk. Any solution to this

问题 Does anyone know how to check for this? I just bought a Samsung Galaxy Tab 2 (7" version running Android 4.0.3) with the intention of using it to connect to my Arduino Mega ADK board. But I am unsure if the galaxy tab has the necessary Open Accessory Mode listed here: http://developer.android.com/guide/topics/usb/adk.html It seems that just because the software is right doesn't mean that the device is compatible and this varies per manufacture. Since this is a new tablet I am not finding

问题 Unfortunately, the Samsung Galaxy Tab 10.1 I received at Google IO does not support accessory mode (http://stackoverflow.com/questions/6355031/how-can-i-get-the-adk-demokit-example-working-on-a-google-i-o-galaxy-tab-10-1). Which Android tablet currently does? I spoke with one of the Google engineer's at the conference who was running the DemoKit app on a tablet, but I didn't catch which one he was using, and whether that device was rooted or not. Is there a tablet out there running Honeycomb
