之前用的一直都是

    /**          * 获取视频缩略图          * @param videoPath          * @param width          * @param height          * @param kind          * @return          */           private Bitmap getVideoThumbnail(String videoPath, int width , int height, int kind){            Bitmap bitmap = null;            bitmap = ThumbnailUtils.createVideoThumbnail(videoPath, kind);            bitmap = ThumbnailUtils.extractThumbnail(bitmap, width, height, ThumbnailUtils.OPTIONS_RECYCLE_INPUT);          return bitmap;           }

但是发现在2.x系统下可用，API LEVEL > 14时却只能返回null

通过上网搜索发现http://www.tuicool.com/articles/uqmUFfY：

import android.media.MediaMetadataRetriever; import android.provider.MediaStore.Images;import java.util.HashMap;import android.os.Build;        /**          * 获取视频缩略图          * @param videoPath          * @param width          * @param height          * @param kind          * @return          */        private Bitmap createVideoThumbnail(String url, int width, int height,int kind) {        Bitmap bitmap = null;        MediaMetadataRetriever retriever = new MediaMetadataRetriever();        //int kind = MediaStore.Video.Thumbnails.MINI_KIND;        try {          if (Build.VERSION.SDK_INT >= 14) {            retriever.setDataSource(url, new HashMap<String, String>());          } else {            retriever.setDataSource(url);          }          bitmap = retriever.getFrameAtTime();        } catch (IllegalArgumentException ex) {          // Assume this is a corrupt video file        } catch (RuntimeException ex) {          // Assume this is a corrupt video file.        } finally {          try {            retriever.release();          } catch (RuntimeException ex) {            // Ignore failures while cleaning up.          }        }        if (kind == Images.Thumbnails.MICRO_KIND && bitmap != null) {          bitmap = ThumbnailUtils.extractThumbnail(bitmap, width, height,              ThumbnailUtils.OPTIONS_RECYCLE_INPUT);        }        return bitmap;  }

完美解决！！
