在我的Android logcat的日誌，我看到：爲什麼機器人在對待ANR程序的時候是在彎針等
01-02 02:01:46.523 E/ActivityManager( 459): ANR in com.android.phone (com.android.phone/.InCallScreen)
，然後當我去/data/anr/traces.txt，我見
Cmd line: com.android.phone

我的問題是爲什麼android認爲應用程序在ANR中時，堆棧跟蹤顯示Looper等待消息中的主線程？這對我來說似乎很正常。當主線程正在下載某個東西/執行長操作時，我明白android顯示ANR。但它似乎很正常，它正在等待一條消息。如果我錯了，請覈對我。
