在這個應用程序，我試圖讓一個小的Button橫跨屏幕移動，並讓用戶嘗試並避免屏幕上緩慢下降的塊。應用程序凍結，Android工作室錯誤？

多其餘的文件是相似的。這些文件爲點之間的過渡設置了動畫。按鈕將在三個不同的區域之間移動。這意味着動畫並不是那麼重要，因爲它們可以工作，當我點擊文本視圖時，應用程序會凍結。這也是在主循環被調用時。這可能是問題嗎？

當我運行的應用程序我三星Galaxy S5，其中具有足夠的RAM和內存，程序凍結和錯誤出現說該應用程序已停止加工。
任何想法？
當應用程序凍結時，您可以顯示log cat的輸出嗎？ –
我已更新它，包括logcat –
這是錯誤日誌嗎？我認爲這不是應用程序凍結的地方。 –
