Problem
Assume we have a heavyweight window, and a service with START_REDELIVER_INTENT. If the app is closed (for low memory, or any other reason), and the service is restarted by the OS, launching the app shows only a black screen.
What's Worse
Because heavyweight/lightweight is being antiquated, and every window will now be heavyweight, the latest master builds exhibit this problem on every window. Using older versions of the SDK (3.1.3.GA), making the window lightweight would avoid this issue, somewhat, but properties like exitOnClose don't work properly.
Example
Follow the 4 steps in the app to reproduce this.
{panel:title=app.js}
// Make a window.
var win = Ti.UI.createWindow({
backgroundColor: 'white'
});
win.add(Ti.UI.createLabel({
text: 'Great! Please:' +
'\n' +
'1) press the home button,\n' +
'2) force-close the app,\n' +
'3) watch the logs for the service to restart itself,\n' +
'4) then try to launch the app again (it should be black).',
left: 20, right: 20
}));
win.open();
// Start an interval service.
var intent = Ti.Android.createServiceIntent({
url: 'service.js',
startMode: Ti.Android.START_REDELIVER_INTENT
});
intent.putExtra('interval', 1000);
Ti.Android.startService(intent);{panel}
{panel:title=service.js}
console.log('Hello from service.js!');{panel}
{panel:title=tiapp.xml}
<android xmlns:android="http://schemas.android.com/apk/res/android">
<services>
<service type="interval" url="service.js"/>
</services>
<manifest android:versionCode="100" android:versionName="1.0.0"/>
</android>{panel}

I can't reproduce this issue, even on 3.1.3.GA. I killed the app, waited for the service to restart, and the launched the app again, and I don't see a black screen. I did notice that there are two instances of the service running.
Did you try with the latest master? Do you have
Just tried this on master, without the setting the useLegacyWindow flag, and a clean build. I could not reproduce the issue. Maybe there is something special in your project? Could you attach a project that shows this behavior?
Closing ticket as the issue cannot be reproduced.
