Answer 1

ANR超时在File InputDispatcher.cpp(frameworks\base\libs\ui)中定义.复制并粘贴下面的那段代码.

// Default input dispatching timeout if there is no focused application or paused window
// from which to determine an appropriate dispatching timeout.
const nsecs_t DEFAULT_INPUT_DISPATCHING_TIMEOUT = 5000 * 1000000LL; // 5 sec
