After writing the ALTER function block, add it before the Alter.show () statement: Alert.getwindow (). SetType (WindowManager.LayoutParams.TYPE_SYSTEM_ALERT); NOTE: Alter is an Alertdialog type Object Then add the permissions in the Androidmanifest.xml: The following is a simple explanation: If you write only the code of the create alter that is used in the activity in the service, the runtime is wrong, because the alter display needs to be dependent on a certain activity class. And the above

Recent projects need to dynamically create a single-selection marquee.The general idea is:1. Dynamically create a radiogroup.2. Create the RadioButton dynamically and add it to the Radiogroup.If you inherit RadioButton, and radiogroup to achieve a variety of other words, accidentally will encounter a variety of diseases.(Ah ah ah, radiogroup I will give you a lot of small monkeys).The most common is the state disorder of RadioButton:(1) A RadioButton is not selected, usually the first one.(2) Ev

QuickTime plugin, but we want a pure browser video stream.Another notable option is Flash Player, which can receive rtmp streams obtained through Wowza conversion rtsp/rtp/h.264. But Flash Player is also a browser plugin, although it is more popular than VLC and QuickTime.In our scenario, we test the same RTSP/RTP stream, but use the WEBRTC compatible browser as the player to play the video without any additional plugins. We set up a conversion server that gets the video stream from the webcam,
