actually made app detects shaking of device , responds. responds when give command change label.text names or when call function contains audio recording functions crashes. here code:-

from kivy.app import app kivy.lang import builder kivy.clock import clock plyer import accelerometer kivy.uix .relativelayout import relativelayout kivy.properties import objectproperty, numericproperty  builder.load_string(""" <accel>:     boxlayout:         orientation:'vertical'          label:             id: x_val             text: 'x:'         label:             id: y_val             text: 'y:'         label:             id: z_val             text: 'z:'          label:             id: x_tst             text: 'value:'      boxlayout:         size_hint_y: none         height: '48dp'         padding: '4dp'          togglebutton:             id: start_btn             text: 'start accelerometer'             on_press: root.accelerometer() """)  class accel(relativelayout):       audio = objectproperty()     time = numericproperty()      has_record = false      def __init__(self):         super(accel, self).__init__()         self.sensorenabled=false         self.counter=0         self.x_axis=[0,0,0,0,0]         self.pan=0      def record(self):          state = self.audio.state         if state == 'ready':             self.audio.start()             self.ids.x_tst.text = "recording started"      def accelerometer(self):           if not self.sensorenabled:             accelerometer.enable()             clock.schedule_interval(self.accelerate, 1/5)             self.sensorenabled =true             self.ids.start_btn.text="stop"         else:             accelerometer.disable()             clock.unschedule(self.accelerate)             self.sensorenabled =false             self.ids.start_btn.text = "start"      def accelerate(self,dt):         val=accelerometer.acceleration[:3]           if not val==(none,none,none):             self.ids.x_val.text="x:" +str(val[0])             self.ids.y_val.text="y:" +str(val[1])             self.ids.z_val.text="z:" +str(val[2])                if self.counter<5:                 self.x_axis[self.counter] = val[0]                 self.k=self.x_axis[self.counter]-self.x_axis[self.counter-1]                 if self.k>8:                     self.record()                 self.counter += 1             else:                 self.counter=0  class meterapp(app):     def build(self):         return accel()  if __name__=="__main__":     meterapp().run()
