我已經創建了一個類和一個BroadcastReceiver，以便在行走或運行結束時從意識API獲取回調。 我沒有得到及時的回調，起初我以爲是因爲我註冊了一個'停止'回調，但是在將手機關機後，我確實收到了幾次回調！但這與我停止行走的時間相距甚遠。停車後至少5分鐘。 即使Google健身應用記錄活動，有時候我也不會收到回傳。Awareness API顯着延遲活動回調
由於我已經得到回調至少幾次，我知道註冊是好的。爲什麼這些電話會延遲並且有時會丟失？
對於背景參考，我將這些回調註冊在onStart主活動上，即啓動感知當時在活動的onstart內被調用。我從來沒有取消他們的註冊。 我不打算在生產中以這種方式使用它，它只是用於測試。再加上我的註冊應用程序上下文失敗的原因。
以下是我設置的Google客戶端和柵欄的註冊助手類。
public class AwarenessHelper {
public static final String WALKING_ENDED_FENCE = "walkingEndedKey";
public static final String RUNNING_ENDED_FENCE = "runningEndedKey";
public static final String TYPE_2_WALKING = "duringWalkingKey";
public static final String TYPE_2_RUNNING = "duringRunningKey";
private String tag = AwarenessHelper.class.getSimpleName();
public void initiateAwareness(final Activity context)
{
final GoogleApiClient googleApiClient = buildClient(context);
Log.d(tag, "Initiating blocking connect");
googleApiClient.registerConnectionCallbacks(new GoogleApiClient.ConnectionCallbacks() {
@Override
public void onConnected(@Nullable Bundle bundle) {
if (googleApiClient.isConnected())
{
Log.d(tag, "Client connected, initiating awareness fence registration");
registerAwarenessFences(context, googleApiClient);
}
else
{
Log.d(tag, "Couldn't connect");
}
}
@Override
public void onConnectionSuspended(int i) {
}
});
googleApiClient.connect();
}
private void registerAwarenessFences(Context context, GoogleApiClient mGoogleApiClient) {
Awareness.FenceApi.updateFences(
mGoogleApiClient,
new FenceUpdateRequest.Builder()
.addFence(WALKING_ENDED_FENCE, DetectedActivityFence.stopping(DetectedActivityFence.WALKING), getBroadcastPendingIntent(context))
.addFence(RUNNING_ENDED_FENCE, DetectedActivityFence.stopping(DetectedActivityFence.RUNNING), getBroadcastPendingIntent(context))
.addFence(TYPE_2_WALKING, DetectedActivityFence.during(DetectedActivityFence.WALKING), getBroadcastPendingIntent(context))
.addFence(TYPE_2_RUNNING, DetectedActivityFence.stopping(DetectedActivityFence.RUNNING), getBroadcastPendingIntent(context))
.build())
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(@NonNull Status status) {
if (status.isSuccess()) {
Log.i(tag, "Fence was successfully registered.");
} else {
Log.e(tag, "Fence could not be registered: " + status);
}
}
});
}
private GoogleApiClient buildClient(final Activity activity)
{
GoogleApiClient client = new GoogleApiClient.Builder(activity)
.addApi(Awareness.API)
.addOnConnectionFailedListener(new GoogleApiClient.OnConnectionFailedListener() {
@Override
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {
if (connectionResult.hasResolution() && connectionResult.getErrorCode() == CommonStatusCodes.SIGN_IN_REQUIRED)
{
try {
connectionResult.startResolutionForResult(activity, GOOGLE_FIT_AUTHORIZATION_REQUEST_CODE);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
}
}
})
.build();
return client;
}
private PendingIntent getBroadcastPendingIntent(Context context)
{
Intent intent = new Intent(AWARENESS_BROADCAST_ACTION);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
return pendingIntent;
}
}

我得到的通知，但大規模的延遲後，有時根本沒有。 我開始多次活動，所以也許圍欄被反覆註冊？這是一個相關的事實嗎？ 也是一個服務或廣播接收機上下文適合感知客戶端和圍牆的初始化？
