In my application I have a feature like Google Maps' shake to feedback so I initialized the seismic inside my BaseActivity and extend every Activity from that. This causes leaks, is there another way to have shake detection in every activity I have?

Samsung overrides motion gestures like shake and it seems like this library is not compatible with their modified Android system. If there is a secret device setting to make it work, please document it.

I'm trying to do an app that send you notifications every time a certain seismic wave happens,and send you a notification to your phone if you have the app downloaded.

I assume Seismic does not need any specific Proguard protections?

I need to have way more sensitivity.

Half a second, and more than 75 % of samples is not acceptable for my use case. I can pick the phone from table and put it back withou triggering hearShake. And I've senstivity set to 10.

I need to detect the phone flipping over from synchronization cradle.

I've added this library to my android project, but I'm noticing that I've to shake it very hard to trigger the hearShake method, is there a way to set sensitivity? If not, could such methods be publicly exposed?

This is because motorola have a default shake gesture which opens camera. Is there a way to possible override this while using the app?

The results show that the shaking occurs about seven times in two seconds.
However, I want to increase the number of shaking measures.
Can I increase the number of detections per second with the code in the library?

The test:

@Test public void testPurge() {
  ShakeDetector.SampleQueue q = new ShakeDetector.SampleQueue();
  q.add(1, true);
  q.add(2, true);
  q.add(3, true);
  q.add(4, true);
  q.add(5, true);
  q.add(6, true);
  q.add(7, true);
  q.add(8, true);
  q.add(9, true);
  assertThat(q.asList()).hasSize(9);
  q.purge(3);
  assertThat(q.asList()).hasSize(7);
  q.purge(8);
  assertThat(q.asList()).hasSize(4); // MIN_QUEUE_SIZE
}

The last assert fails, the size is 3.

On android 12 a new permission has been added when the sampling rate is set to 0 microseconds. Would be possible to have this value configurable? Are we able to detect the shake gesture with a sampling rate lower than 200 Hz?

The issue that I'm getting right now when initializing the ShakeDetector is this one:

java.lang.SecurityException: To use the sampling rate of 0 microseconds, app needs to declare the normal permission HIGH_SAMPLING_RATE_SENSORS.

In class "Demo" had next line:

package com.squareup.seismic.sample; 

This is a mistake, the correct value:

package main.java.com.squareup.seismic.sample;

I put sd.stop(); in onPause(), onDestroy(), and onBackPressed() but when I leave the application and shake the device on my homescreen for example it still performs the specified action.
