onPause后,PhoneGap会继续在Android上运行 [英] PhoneGap keep running on Android after onPause
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
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
< 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.
