android无法在onstart方法上播放流媒体

public class MainActivity extends AppCompatActivity {
    private VideoView mVideoView;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        mVideoView = findViewById(R.id.videoView);
        // 设置视频路径
        mVideoView.setVideoPath("http://example.com/video.mp4");
        
        // 可选：为VideoView设置相关事件监听器
        mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mp) {
                // 视频准备完成后的回调
                mp.start(); // 开始播放
            }
        });
    }
    
    @Override
    protected void onResume() {
        super.onResume();
        mVideoView.start(); // 在onResume方法中开始播放
    }
}
