ahh, can says on page ted mentioned, , use handler show toast. code need add activity.

private handler handler = new handler;  private broadcastreceiver mbatinforeceiver = new broadcastreceiver() {     @override     public void onreceive(final context context, intent intent) {         int level = intent.getintextra(batterymanager.extra_level, 0);         int scale = intent.getintextra(batterymanager.extra_scale, 100);         log.i(tag, "level: " + level + "; scale: " + scale);         int percent = (level*100)/scale;          final string text = string.valueof(percent) + "%";         handler.post( new runnable() {              public void run() {                 toast.maketext(context, text, toast.length_short).show();             }         });      } };
