oncreate

问题 I created an Android TV app, on the onCreate() the app handles a lot of data which take it few seconds to load up. When I press the home button and the app goes to background, from my experince the app should come up in the same state as it went to background. for some reason the helps get destroyed and onCreate called again which takes a bit of time to load. the following logcat apears when the app goes to the background: onDestroy and onRestart both of them aren't called...

问题 when is the "best moment" to load a new ad from AdMob? I'm programming a shopping list application that has an admob banner on its main screen.

问题 I've recently tried to use StrictMode but got a weird violation, so I tried setting up a new 'Empty Activity' project (in Android Studio ) and added an Application class as follows (as described in here): public class TestApplication extends Application { @Override public void onCreate() { setStrictMode(); super.onCreate(); } private void setStrictMode() { if (BuildConfig.DEBUG) { StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder() .detectAll() .penaltyLog() .build()); StrictMode
