每当我播放媒体时，它都会在DDMS 应该已经设置了字幕控制器中显示警告
我的代码:
private void start() {
mediaPlayer.start();
mediaPlayer.setOnCompletionListener(new OnCompletionListener() {
@Override
public void onCompletion(MediaPlayer mp) {
mp.stop();
mp.release();
}
});
}
DDMS日志(log)
应该已经设置了字幕控制器
信息/警告(2，0)
当我在谷歌上搜索时，甚至没有一个与之相关的主题.我如何摆脱或禁用它？
一位开发商最近added subtitle support to VideoView岁.
当MediaPlayer开始播放音乐(或其他来源)时，它会判断是否有字幕控制器，如果没有设置，则会显示此消息.
Short answer:.不要在意这个"例外".
Edit :个
Lollipop年后仍然存在，
如果MediaPlayer仅用于播放音频文件，并且您确实希望在logcat中删除这些错误，那么下面的代码将empty SubtitleController设置为MediaPlayer.
It should not be used in production environment and may have some side effects.个
static MediaPlayer getMediaPlayer(Context context){
MediaPlayer mediaplayer = new MediaPlayer();
if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.KITKAT) {
return mediaplayer;
}
try {
Class<?> cMediaTimeProvider = Class.forName( "android.media.MediaTimeProvider" );
Class<?> cSubtitleController = Class.forName( "android.media.SubtitleController" );
Class<?> iSubtitleControllerAnchor = Class.forName( "android.media.SubtitleController$Anchor" );
Class<?> iSubtitleControllerListener = Class.forName( "android.media.SubtitleController$Listener" );
Constructor constructor = cSubtitleController.getConstructor(new Class[]{Context.class, cMediaTimeProvider, iSubtitleControllerListener});
Object subtitleInstance = constructor.newInstance(context, null, null);
Field f = cSubtitleController.getDeclaredField("mHandler");
f.setAccessible(true);
try {
f.set(subtitleInstance, new Handler());
}
catch (IllegalAccessException e) {return mediaplayer;}
finally {
f.setAccessible(false);
}
Method setsubtitleanchor = mediaplayer.getClass().getMethod("setSubtitleAnchor", cSubtitleController, iSubtitleControllerAnchor);
setsubtitleanchor.invoke(mediaplayer, subtitleInstance, null);
//Log.e("", "subtitle is setted :p");
} catch (Exception e) {}
return mediaplayer;
}
此代码try 从隐藏的API执行以下操作
SubtitleController sc = new SubtitleController(context, null, null);
sc.mHandler = new Handler();
mediaplayer.setSubtitleAnchor(sc, null)
