问题描述
function test2(x){
$('< div>< / div>',{text:x.cmd})。appendTo($('#list'));
}
$(function(){test2({cmd:start});});
function cb_pause(){test2({cmd:pause});}
function cb_resume(){test2({cmd:resume});} {test2({cmd:timer+ timer}); timer ++; setTimeout(tick,1000);}
document.addEventListener(pause,cb_pause,false);
document.addEventListener(resume,cb_resume,false);
tick();
打印暂停和<$ c $在 onPause 和 onResume 上键入 resume 。
并每秒打印 timer0 , timer1 等。
即使我离开应用程序并开始玩游戏,它也在打印。
我知道我可以并应该停止定时器在 onPause 但仍然。它看起来错了。我期望android会冻结WebView。
我知道后台线程在后台应用程序中不会停止,直到它被卸载。
所以问题是:有办法在 onPause 上冻结/暂停/卸载webview,并解冻/恢复/加载 onResume
当我说载入时,我的意思是当用户离开应用程序时应处于相同的状态。
当我说冻结,我的意思是我的代码将暂停,即使它会继续调用 setTimeout
I猜猜我期望Android的行为像iOS。
我迟到了回复。在phonegap中有 KeepRunning param在 config.xml
您必须在 config.xml
中添加以下行:< platform name =android>
...
< preference name =KeepRunningvalue =false/>
它会调用 pauseTimers()所有WebViews。 pauseTimers()不是隐藏的方法,不需要反射。
I decided to test if phonegap WebView is live when app is in a background.
function test2(x){ $('<div></div>', {text: x.cmd}).appendTo($('#list')); } $(function(){test2({cmd:"start"});}); function cb_pause(){test2({cmd:"pause"});} function cb_resume(){ test2({cmd:"resume"});} function tick(){test2({cmd:"timer" + timer});timer++;setTimeout(tick, 1000);} document.addEventListener("pause", cb_pause, false); document.addEventListener("resume", cb_resume, false); tick();
It prints pause and resume on onPause and onResume.and print timer0, timer1, etc every second.
It was printing even when I left app and started playing game.I know I can and should stop timer in onPause but still. It looks wrong. I expected android will freeze WebView.
I know background thread will not stop if in background app until it is unloaded.
So question is: Is there way to freeze/suspend/unload webview on onPause and unfreeze/resume/load on onResume
When I say load I mean it should be in same state when user left app.
When I say freeze, I mean that my code to will pause even when it will continue to call setTimeout
I guess I expect Android to behave like iOS.
I am late with response. In phonegap there is KeepRunning param in config.xml
You must add following line to config.xml
<platform name="android"> ... <preference name="KeepRunning" value="false" />
It will call pauseTimers() and pause all WebViews. pauseTimers() is not hidden method and no reflection is needed.
