你好,谁能告诉我如何将mp3 / mp4播放到Android默认浏览器?

我的资源中的原始文件夹中有mp3 / mp4文件。

我尝试过以下代码,但却无视并且无法正常工作,它会打开默认播放器,但没有播放所选文件。

String dataResourceDirectory = "raw";
String dataResoruceFilename = "armin";

Uri uri = Uri.parse("android.resource://" + getPackageName() + "/" + dataResourceDirectory + "/" + dataResoruceFilename);

Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);

File file = new File(uri);
intent.setDataAndType(Uri.fromFile(file), "audio/*");

startActivity(intent);

有人可以建议吗?

您无法将应用程序的私有包中的视频播放到默认视频播放器,因为您的默认视频播放器无法识别此路径。

解决方案1 ​​以SD卡复制文件

File sdCard = Environment.getExternalStorageDirectory();
File dir = new File (sdCard.getAbsolutePath() + "/myfolder");
File video = new File (sdCard.getAbsolutePath() + "/myfolder/video.mp4");
if(!dir.isDirectory()) dir.mkdirs();
if(!video.isFile()){
   InputStream ins = getResources().openRawResource(R.raw.test);
   int size;
   try {
     size = ins.available();
     byte[] buffer = new byte[size];
     ins.read(buffer);
     ins.close();
     FileOutputStream fos = new FileOutputStream(new File(dir,"video.m4v"));
     fos.write(buffer);
     fos.close();
  } catch (IOException e) {
      e.printStackTrace();
  }
}

File myvid = new File(dir, "video.m4v");
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(myvid), "video/*");
this.startActivity(intent);

解决方案2 启动视频观看视频播放器

VideoView videoView = (VideoView)findViewById(R.id.myvideoview);
MediaController mediaController = new MediaController(this);
mediaController.setAnchorView(videoView);
videoView.setMediaController(mediaController);
String path = "android.resource://" + getPackageName() + "/" + R.raw.video_name_without_extension;
videoView.setVideoPath(path);
videoView.start();
