vibration

问题 Ok so I'm very new to android. My gf asked me to make a very simple app for her so she could easily switch from always vibrate to never vibrate. Seemed like a simple enough task. So I've got a toggle button, and it changes the setting, but I keep running into one big issue. It won't change between always and never. if I set it to always it will swap between always and only in silent mode, or if I set it to never it switches between only not in silent mode and never. did I miss some obvious

问题 i made an app that messes with the system vibrate settings. namely, it turns them off. AudioManager audioManager = (AudioManager)ctx.getSystemService(Context.AUDIO_SERVICE); audioManager.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER, AudioManager.VIBRATE_SETTING_OFF); audioManager.setVibrateSetting(AudioManager.VIBRATE_TYPE_NOTIFICATION, AudioManager.VIBRATE_SETTING_OFF); System.putInt(ctx.getContentResolver(), VIBRATE_IN_SILENT, 0); i wonder now, where i can turn the vibration manually

问题 I would write as much as I could write here, but the Title pretty much says it all. I've tested it in several different situations: 1) Phone on, silent mode off, app on, in foreground, screen unlocked I know that this goes through app delegate's didReceiveLocalNotification and didn't expect a sound or vibration, except for the handling code that I included under didReceiveLocalNotification. The handling code actually called NSURL *Sound = [[NSBundle mainBundle] URLForResource: self

问题 I'm making a vibrate toggling widget (in fact, its first version is already in the Market) but I'm having some problems with the vibrate settings of Android 2.2. Up to Android 2.1 I have no problem, when I want to disable vibrate I do am.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER,AudioManager.VIBRATE_SETTING_OFF); am.setVibrateSetting(AudioManager.VIBRATE_TYPE_NOTIFICATION,AudioManager.VIBRATE_SETTING_OFF); and the same but with VIBRATE_SETTING_ON on both lines to turn it on, and it

问题 I am trying to create an android application where I filter one specific frequency of a beep and make the phone vibrate. I am taking input from the MIC of mobile and using MediaRecorder class, by using this class, I can record, save and play the input. Now I need my mobile to vibrate whenever there is a beep/or any sound. The input is given by a wire to the Headphone jack of the mobile so I know that there is only one frequency being input. I have a button, Clicking which starts recording. I

问题 How can I manually trigger a single click-like vibration like the ones that happen when using peek&pop, or application shortcuts? 回答1: It seems that these guys have found a way to do it for iOS 9 for phones with Taptic Engine (including the iPhone 6S). http://unifiedsense.com/development/using-taptic-engine-on-ios.html I'm not sure if it applies to iOS 8 or any other phones. They've essentially retrieved the Taptic Engine interface from UIDevice and called actuateFeedback with an integer
