刪除接近警報不起作用

Question

我有刪除接近警報的問題，並且對於測試，我嘗試添加ProximityAlert並在之後立即將其刪除。 我有這樣的功能：

public void addproximity(View v) { 
    SharedPreferences sharedPref = getSharedPreferences("proximityService", Context.MODE_PRIVATE); 

    int unique_id = sharedPref.getInt("PENDING_ID", 0); 
    unique_id = unique_id+1; 

    SharedPreferences.Editor editor = sharedPref.edit(); 
    editor.putInt("PENDING_ID", unique_id); 
    editor.commit(); 
    Intent intentNew = new Intent(PROX_ALERT_INTENT); 

    LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 

    double latitude = 43.9297615; 
    double longitude = 10.2035046; 
    PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), unique_id, intentNew, 0); 
    lm.addProximityAlert(latitude, longitude, 200, -1, pi); 
    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { 
     return; 
    } 
    IntentFilter filter = new IntentFilter(PROX_ALERT_INTENT); 
    mHandleMessageReceiver = new ProximityAlertReceiver(); 
    registerReceiver(mHandleMessageReceiver, filter); 


    lm.removeProximityAlert(pi); 

} 

但我用假的GPS測試，接近不刪除，廣播仍然收到事件。 我錯了什麼？

in addProximityAlert()您正在傳遞-1作爲到期值的方法，這意味着您的geofrence不會過期（Geofence.NEVER_EXPIRE）。這就是geofrence不能移除的原因。更改此標誌並重試。
