Example 61 with HandlerThread

use of android.os.HandlerThread in project android_frameworks_base by ResurrectionRemix.

the class MediaPlayer method addTimedTextSource.

/**
     * Adds an external timed text file (FileDescriptor).
     *
     * It is the caller's responsibility to close the file descriptor.
     * It is safe to do so as soon as this call returns.
     *
     * Currently supported format is SubRip. Note that a single external timed text source may
     * contain multiple tracks in it. One can find the total number of available tracks
     * using {@link #getTrackInfo()} to see what additional tracks become available
     * after this method call.
     *
     * @param fd the FileDescriptor for the file you want to play
     * @param offset the offset into the file where the data to be played starts, in bytes
     * @param length the length in bytes of the data to be played
     * @param mime The mime type of the file. Must be one of the mime types listed above.
     * @throws IllegalArgumentException if the mimeType is not supported.
     * @throws IllegalStateException if called in an invalid state.
