问题 I have an Android Wear watch face that I'm trying to have vibrate the watch on the hour. It is working except in cases where the watch screen is off. According to the log statements, the handler method is called every minute and the chime method is called on the hour. If I'm debugging over bluetooth with the Moto 360, it works even with the screen off. If I install a release apk, it only vibrates if the screen is on. If the screen is off at the top of the hour, it wont vibrate until the

问题 I have used the below code to vibrate the device. public void vibrator() { try { Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); vibrator.vibrate(5000); } catch (Exception e) { Log.d(TAG, "vibrator exception: " + e); } } Can we programmatically detect this event (check is device vibrating)? 回答1: No, you can't. Same question is here. You can check only if the device vibrating is supported: Vibrator mVibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);

问题 Somehow tricky question. I am working with one app through which user can set incoming call custom ringtone and different vibration level for different contacts. I have stuck with vibration level setting. We can set vibration level using, Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); // 1. Vibrate for 1000 milliseconds long milliseconds = 1000; v.vibrate(milliseconds); // 2. Vibrate in a Pattern with 500ms on, 500ms off for 5 times long[] pattern = { 500, 300 }; v

问题 Guys my phone is vibration without any reason. So I want to determine the application which sends vibration command to vibrate. Does Android logging such events? Or can I write an application which will monitor Vibrator::vibrate(TIMEOUT) calls from another application? Note: I have root access. 回答1: If you look in the system log ( logcat -b system ) it will show you the core system service's logs. The VibrateService only makes a couple in the latest version of Android, which will tell you
