Android アプリで動画をストリーミングするための簡単なコードを作成しました。私は Vitamio Library を使用し、プロジェクトに統合するために必要なすべての手順に従いました。ビデオが再生されず、ロード時にアプリがクラッシュします。
package com.test.bufferapp;
import io.vov.vitamio.LibsChecker;

import io.vov.vitamio.widget.MediaController;
import io.vov.vitamio.widget.VideoView;

private VideoView mVideoView;
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
if (!LibsChecker.checkVitamioLibs(this))
return;
setContentView(R.layout.activity_main);

mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer mediaPlayer) {
// optional need Vitamio 4.0
mediaPlayer.setPlaybackSpeed(1.0f);
}
