如何将从一个活动录制的视频发送到另一个活动？

Question

我正在尝试将我录制的视频从一个活动发送到另一个活动。我想发送地址但不能这样做。

    public void startRecordingVideo(View view) {
    if (getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_FRONT)) {
        Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
        File mediaFile = new File(
                Environment.getExternalStorageDirectory().getAbsolutePath() + "/myvideo.mp4");
        videoUri = Uri.fromFile(mediaFile);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, videoUri);
        startActivityForResult(intent, VIDEO_CAPTURE);
    } else {
        Toast.makeText(this, "No camera on device", Toast.LENGTH_LONG).show();
    }
}

public void convert（查看视图）{

    Intent i = new Intent(getApplicationContext(),convertVid.class);
    File mediaFile = new File(
            Environment.getExternalStorageDirectory().getAbsolutePath() + "/myvideo.mp4");
    videoUri = Uri.fromFile(mediaFile);
    i.putExtra("video1",videoUri);
    startActivityForResult(i,1);
}

}
