在個別機型PopupWindow動畫結束後dismiss崩潰，日誌：

<pre name="code" class="plain">E/libEGL(28187): call to OpenGL ES API with no current context (logged once per thread)

可能是bug，導致onAnimationEnd在錯誤的執行緒執行或者狀態錯誤之類的，修改後問題解決：

public static PopupWindow showGainCoinPopup(Activity activity, View parent, int coinCount, final Runnable runnable){
		LayoutInflater li = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
		View v = li.inflate(R.layout.popupwindow_get_coin, null);
		TextView textGetCoin = (TextView) v.findViewById(R.id.textGetCoin);
		textGetCoin.setText("+" + coinCount + "金幣");

		final PopupWindow pw = new PopupWindow(v, LayoutParams.WRAP_CONTENT, LayoutParams.MATCH_PARENT);
		pw.setBackgroundDrawable(new BitmapDrawable());
		pw.setOutsideTouchable(false);
		pw.setFocusable(false);
		//pw.setAnimationStyle(R.anim.popup_enter);

		TranslateAnimation ani = new TranslateAnimation(0, 0, 0, -150);
		ani.setDuration(700);
		ani.setAnimationListener(new AnimationListener() {
			
			@Override
			public void onAnimationStart(Animation animation) {
			}
			
			@Override
			public void onAnimationRepeat(Animation animation) {
			}
			
			@Override
			public void onAnimationEnd(Animation animation) {
				
				// 在有些手機中dismiss會崩潰
				new Handler().post(new Runnable() {
		            @Override
		            public void run() {
		            	if (runnable!=null){
							runnable.run();
						}
						pw.dismiss();
		            }
		        });
			}
		});
		pw.showAtLocation(parent, Gravity.CENTER, 0, 0);
		v.startAnimation(ani);
		return pw;
	}
