[英]HeadphoneFence.unplugged in the Google Awareness API fires regardless of the state
我正在使用Nexus 5X手机并尝试使用Google Awareness API HeadphoneFence.unplugged() https://developers.google.com/android/reference/com/google/android/gms/awareness/fence/HeadphoneFence
我发现,第一次添加围栏时,它会触发我的未决意图,然后无论我插入或拔出耳机,它都将触发,即使它只是为拔出插头而触发。
我的代码不是很有趣,因为它直接来自指南。
Awareness.FenceApi.updateFences(
getGoogleApiClient(),
new FenceUpdateRequest.Builder()
.addFence(
"something",
HeadphoneFence.unplugging();,
createSendHeadphoneUnpluggedMessagePendingIntent(context))
.build())
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(@NonNull Status status) {
if(status.isSuccess()) {
Log.i(TAG, "Headphone unplugged fence was successfully registered.");
} else {
Log.e(TAG, "Headphone unplugged fence could not be registered: " + status);
}
}
});
@Herman似乎的确是这样。 它会在启动应用程序时(注册了围栏/接收器时)以及在您插入/拔下耳机时为您提供耳机的状态。
从某种程度上讲,我认为这是有道理的,如果连接了耳机,则您没有拔掉它们,因此它会触发FenceState.FALSE,而当您拔下它们时,它将触发FenceState.TRUE。 但是,您可以选择在
switch (fenceState.getCurrentState()) {
case FenceState.TRUE:
Log.i(TAG, "Fence > Headphones plugged out");
break;
case FenceState.FALSE:
Log.i(TAG, "Fence > Headphones are NOT plugged out.");
break;
case FenceState.UNKNOWN:
Log.i(TAG, "Fence > The headphone fence is in an unknown state.");
break;
}
