古い質問であることは知っていますが、正しい答えが見つかりません。MMS 経由でビデオを共有したいのですが、「添付できません。ファイルがサポートされていません」というエラーが表示され続けます。
以下は私のコードです。最初は私のレコーディングクラスで、2番目はビデオプレーヤーです:
public class VideoComponent extends Activity {
private SurfaceHolder surfaceHolder;
private SurfaceView surfaceView;
public MediaRecorder mrec = new MediaRecorder();
private Button startRecording = null;
private Button stopRecording = null;
private Button play = null;
private Button gallery = null;
int BytesPerElement = 2;
File video;
private Camera mCamera;
File audiofile = null;
boolean recording=false;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main1);
startRecording = (Button)findViewById(R.id.buttonstart);
stopRecording = (Button)findViewById(R.id.share);
play=(Button)findViewById(R.id.play);
gallery= (Button)findViewById(R.id.gallery);
mCamera = Camera.open();
surfaceView = (SurfaceView) findViewById(R.id.surface_camera);
surfaceHolder = surfaceView.getHolder();
surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
startRecording.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
if(recording==false)
startRecording();
} catch (IOException e) {
Log.i("test" , "Video Not starting");
}
}
});
stopRecording.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
recording=false;
stopRecording();
}
});
play.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i= new Intent(getApplicationContext(),VideoPlayer.class);
i.putExtra("URI", audiofile.getAbsolutePath());
startActivity(i);
}
});
gallery.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i= new Intent(getApplicationContext(),Gallery.class);
startActivity(i);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
Log.i("Test" , "Menu thing");
menu.add(0, 0, 0, "StartRecording");
menu.add(0, 1, 0, "StopRecording");
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case 0:
try {
Log.i("Test" , "Start Recording");
startRecording();
} catch (Exception e) {
String message = e.getMessage();
Log.i("Self", "Problem Start"+message);
mrec.release();
}
break;
case 1: //GoToAllNotes
mrec.stop();
mrec.release();
mrec = null;
break;
default:
break;
}
return super.onOptionsItemSelected(item);
}
public void startRecording() throws IOException
{
recording=true;
String path= Environment.getExternalStorageDirectory().toString();
File sampleDir = new File(path+"/DCIM/Camera");
sampleDir.mkdir();
Log.i("Setting Path", sampleDir.toString());
try {
audiofile = File.createTempFile("Video", ".3gp", sampleDir);
} catch (IOException e) {
return;}
int minBufferSize = AudioRecord.getMinBufferSize(8000,
AudioFormat .CHANNEL_IN_MONO,
AudioFormat.ENCODING_PCM_16BIT);
mrec = new MediaRecorder(); // Works well
mCamera.unlock();
mrec.setCamera(mCamera);
mrec.setPreviewDisplay(surfaceHolder.getSurface());
mrec.setVideoSource(MediaRecorder.VideoSource.CAMERA);
mrec.setAudioSource(MediaRecorder.AudioSource.MIC);
mrec.setMaxDuration(60000);
mrec.setAudioSamplingRate(16000);
mrec.setProfile(CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH));
mrec.setPreviewDisplay( surfaceHolder.getSurface());
mrec.setOutputFile(audiofile.getAbsolutePath());
mrec.prepare();
mrec.start();
}
protected void stopRecording() {
mrec.stop();
mrec.release();
mCamera.lock();
mCamera.release();
Log.i("testing","going to call Destroyer");
//surfaceDestroyed(surfaceHolder);
//mCamera.stopPreview();
//finish();
}
private void releaseMediaRecorder(){
Log.i("testing","re;ease Media record");
if (mrec != null) {
mrec.reset(); // clear recorder configuration
mrec.release(); // release the recorder object
mrec = null;
mCamera.lock(); // lock camera for later use
}
}
private void releaseCamera(){
Log.i("testing","re;ease Camera");
if (mCamera != null){
mCamera.release(); // release the camera for other applications
mCamera = null;
}
}
}
これは私の Video Player クラスです
public class VideoPlayer extends Activity {
VideoView videoView;
Button mms=null;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
//Create a VideoView widget in the layout file
//use setContentView method to set content of the activity to the layout file which contains videoView
this.setContentView(R.layout.video);
final Intent i= getIntent();
final String uri=i.getStringExtra("URI");
Log.i("URI","Path is"+Uri.parse(uri));
mms=(Button)findViewById(R.id.mms);
videoView = (VideoView)this.findViewById(R.id.videoView1);
//add controls to a MediaPlayer like play, pause.
MediaController mc = new MediaController(this);
videoView.setMediaController(mc);
//Set the path of Video or URI
videoView.setVideoURI(Uri.parse(uri));
//Set the focus
videoView.requestFocus();
videoView.start();
mms.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(Intent.ACTION_SEND);
i.setClassName("com.android.mms", "com.android.mms.ui.ComposeMessageActivity");
i.putExtra(Intent.EXTRA_STREAM,Uri.parse(uri));
i.setType("video/*");
startActivity(i);
}
});
}
}

編集: ファイル形式は .3gp です。電子メールで機能しているため、パスに問題はありません。EDIT # 2: 完全なコードが添付されています。ビデオの uri を正しく渡す際に問題がないか確認してください。
