Turn from: hereIn Android app development, there are occasional exceptions that cause the app being used to be abnormal and forced to shut down, which leads to an unfriendly user experience. To solve this problem, we need to catch the exception and do the processing. There are two kinds of exceptions in Java, namely error and RuntimeException, the former do not need us to deal with, we often deal with the l

As an audio hub in an Android system, it is also a system service that restarts (providing access to the upper layer) to the boot (to manage audio devices through the HAL). Only by understanding the Audioflinger can we use this as a basis for better depth to other modules, so we put it in front

The next time the Action_down event occurs, it will still be delivered to the view.Additional notes:If it is intercepted in the process of passing down, that is, the Onintercepttouchevent method returns True, then the event will stop passing down, directly by the current Ontouchevent method, if the processing succeeds OK, if the processing is unsuccessful, the event will be passed up.Instance code: http://do

Usually our app will only be designed as a horizontal screen or vertical screen, the way to lock the horizontal screen or vertical screen is to set the attribute android:screenorientation "Landscape" or "portrait" in the Manifest.xml file: Android:name= ". Mainactivity " android:label=" @string/app_name " android:screenorientation=" Landscape "; In fact Screenorientation can also be set to many values: android : Screenorie
