The author recently developed the Android mobile app app using Eclipse, and there's actually a feature to load the Web page with the WebView control that comes with the Android system. Development is smooth and browsing is normal. However, one of the more special is that there is a

Android uses WebView to browse a webpage with sound or video. After WebView is disabled, the solution does not stop sound or video. I recently used Eclipse to develop an Android mobile app. In fact, one function is to use the WebView control provided by

Android uses SoundPool to play sound effects, and androidsoundpool In Android development, we often use MediaPlayer to play audio files. However, MediaPlayer has some shortcomings, such as high resource usage, long latency, and not support simultaneous playback of multiple audios. These disadvantages determine that MediaPlayer is not ideal in some scenarios, for

)Rate playback rate (1.0 = normal playback, range 0.5 to 2.0) To use SoundPool to play a sound, follow these steps: Call the SoundPool constructor to create the SoundPool object. Call the load () method of the SoundPool object to load the sound from the specified resource, file, it is best to use HashMap To manage the loaded sounds Call the play method of SoundPool to play the

According to different sounds, music is usually divided into two parts: music and sound effects. Music can be used for background music and is in consideration of performance. If long music is stored in the memory, resource shortage may occur, android is required for general sound effects. media. soundpool implementation. The procedure is as follows: 1. construct

There are unwritten rules in the industry that phone companies must have a prompt when they click the photo and video keys for camera. Therefore, google also put the function of playing the photo sound in the cameraService to prevent developers from developing a non-audible camera. Therefore, as long as the camera function is called, it will surely sound, this is written to the framework. This rule is a bi

, data shows that we use mobile phones to view information on average about 150 times a day. Every time we do this, it is possible to get lost in other applications, often consuming a lot of unnecessary time in a task program, and sometimes even forgetting the most important information we have to query.The first batch of Android Wear hot up is Samsung Gear Live and LG G Watch, the two devices were released at the June Google I/O conference.

When it comes to audio applications, the first thing to think about is the music player. Some players can play streaming media, and some can play local music files. With the evolution of the Android platform, more advanced audio APIs are needed. Fortunately, Google has added this API to support low-latency audio streaming and recording.The Android Audio API offers some advanced features that developers can

I mainly want to summarize the ideas about Android mobile app in the forum. I think they can be implemented or interesting, and they can be used if they are not creative in the future. I also hope to help you. If you have any good ideas, remember to comment and leave a spark of your thoughts !!!!! 1.
