I know that there is too many solutions were given, but I can't get the exact solution. My problem is that I have picked one video from internal storage device and after picking video then I have converted to String and set the video to videoView but then also it shows that "Can't play this video" in videoView.
can anyone please help me to find out the solution :(
here is my code
File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath()+"/Download/videos.mp4");
Log.d("video",""+file);
if (file.exists()) {
Uri uri = Uri.fromFile(file);
String video = String.valueOf(uri);
Log.d("video",""+uri);
videoView.setMediaController(new MediaController(this));
videoView.setVideoURI(Uri.parse(video));
videoView.requestFocus();
videoView.start();
}else {
Toast.makeText(this, "No video found", Toast.LENGTH_SHORT).show();
}
With scoped storage (required from API 30) you can't access files directly unless you request the MANAGE_EXTERNAL_STORAGE (on Google Play you need to request it to Google).
The new way is to use the file uri. You can try those ways:
Ask the user to select the file.
private final ActivityResultLauncher<String[]> openDoc =
registerForActivityResult(new ActivityResultContracts.OpenDocument(),
new ActivityResultCallback<Uri>() {
#Override
public void onActivityResult(Uri uri) {
// use uri
}
});
Call it with:
// Use the mimetype you want (optional). Like "text/plain"
openDoc.launch(new String[]{"text/plain"});

Get the Media file uri with MediaStore

You'll also need the READ_EXTERNAL_STORAGE permission if the file was not created by your app.
I'm developing a stream video app in Android with MediaPlayer. The problem is that I need to show the current bitrate, but I haven't found any valid suggestions on how to do get it?
Here is how I'm setting the video url to play:
mediaPlayer = new MediaPlayer();
try {
mediaPlayer.setDataSource(VIDEO_PATH);
mediaPlayer.prepare();
mediaPlayer.init();
} catch (IOException e) {
e.printStackTrace();
}
I don't know if the only way to get that working is using ExoPlayer (which I've read it may be possible)
Any suggestions?
Thanks!
Apparently you cannot do this with MediaPlayer but you can use MediaMetadataRetriever, which is available since API level 10, i.e., quite a while ago.
int getBitRate(String url) {
final MediaMetadataRetriever mmr = new MediaMetadataRetriever();
try {
mmr.setDataSource(url, Collections.EMPTY_MAP);
return Integer.parseInt(mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_BITRATE));
} catch (NumberFormatException e) {
return 0;
} finally {
mmr.release();
}
}
The disadvantage this can have is that you will make an extra HTTP request for getting the metadata (only an RTT if you are streaming from an URI; if you are reading from an file descriptor it could be more serious). Hopefully no big deal.
I want to play a video from URL by using the Vuforia Android Native API.
I have changed the code in the VideoPlayback sample, as shown below:
VideoPlayback.java
Video from Url
mMovieName[STONES] = "..Youtube Video link..";
mMovieName[CHIPS] = "..Youtube Video link..";
mMovieName[celebVM_LOGO] = "..Youtube Video link..";
I removed some code from VideoPlayerHelper.java as shown below:
for Video from Url, in Load method
AssetFileDescriptor afd = mParentActivity.getAssets().openFd(filename);
mMediaPlayer.setDataSource(afd.getFileDescriptor(),
afd.getStartOffset(), afd.getLength());
afd.close();
Added:
mMediaPlayer.setDataSource(filename);
And removing the code
try {
AssetFileDescriptor afd = mParentActivity.getAssets().openFd(filename);
afd.close();
} catch (Exception e) {
Log.d(LOGTAG, "File does not exist");
mCurrentState = MEDIA_STATE.ERROR;
mMediaPlayerLock.unlock();
mSurfaceTextureLock.unlock();
return false;
}
It's not working, can anybody suggest why? Please refer to this link for more information:
https://developer.vuforia.com/forum/android/how-work-video-url-videoplayback
I believe it will only work with links to the actual videos, for example this one.
mMediaPlayer.setDataSource("../video.mp4"); //or any video type
I am writing code for an Android app using Eclipse that is supposed to download an image from a URL (which is generated by the app, elsewhere in the code, using GPS information), then attach the newly downloaded image to an e-mail to be sent. I am able to, in general, accomplish this without much issue.
My problem is this: I only want one image downloaded by the app to be present in the device's external storage at any given time. Deleting the image after the email intent does not work, because because the app doesn't always call onStop or onDestroy when switching to another app to send the email. Time-sensitive deleting of the image will not work either, because I cannot assume that the user will send only one email from the app per hour. I want to give the user the freedom of sending as many of these emails (with one newly downloaded image, each) as they wish.
My current method (which works MOST of the time) is this: in the downloadFile method, simply check for the file's existence (I call it sensorMap.png), then delete it if it exists, before downloading a new one. This SHOULD ensure that there may be only one sensorMap.png image in external storage at any given time (EDIT: it does do this), and that when it comes time to attach the image to the email intent, there will be exactly one image ready to go. Instead, I see that sometimes a second sensorMap image is sometimes being downloaded into storage (i.e. "sensorMap-1.png"), OR the image cannot be attached to the email due to a "File size: 0 bytes" error, OR the image cannot be attached due to a "File does not exist" error. I am unsure what the difference between the latter two problems is. EDIT: Upon manually examining the contents of the directory I created, it seems that, as intended, I end up with only one image titled "sensorMap.png" at a time; it remains in the directory after the app closes, as expected. However, I still occasionally get the "File size: 0 bytes" message or the "File does not exist." message with no attached image, even though I see that the image DOES exist upon looking in directory afterwards. Other times, everything works just fine. It's rather bewildering.
In addition, there is an issue of the button which sends the email becoming unresponsive occasionally. Most of the time, it prompts the user to select an email client, as intended, but occasionally the button will LOOK as if clicked, but do nothing. When this happens, the logcat does not sense that the button was even clicked (I inserted a println statement to test it).
I am unsure of why my delete-before-download is not working flawlessly; the basic idea, at least, appears to be logically sound. Here is the code pertaining to my issue:
Code used to download file (in MainCountActivity.java):
//Function to download image given URL. Will use to attach image file to email.
public void downloadFile(String uRl) {
//delete existing file first so that only one sensorMap image exists in memory
//at any given time.
File file = new File(Environment.getExternalStorageDirectory()+"/SensorLocationImages");
File checkFile = new File(Environment.getExternalStorageDirectory()+"/SensorLocationImages/sensorMap.png");
if(checkFile.exists())
{
//debugging:
System.out.println("About to delete file!");
//deleteFiles(Environment.getExternalStorageDirectory()+"/SensorLocationImages");
checkFile.delete();
}
DownloadManager mgr = (DownloadManager) getActivity().getSystemService(Context.DOWNLOAD_SERVICE);
Uri downloadUri = Uri.parse(uRl);
DownloadManager.Request request = new DownloadManager.Request(
downloadUri);
request.setAllowedNetworkTypes(
DownloadManager.Request.NETWORK_WIFI
| DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(false).setTitle("Sensor Location Map")
.setDescription("Pinpointed is the location from which the log file was sent.")
.setDestinationInExternalPublicDir("/SensorLocationImages", "sensorMap.png");
mgr.enqueue(request);
}
public Activity getActivity() //I wasn't sure if this would work, but it did. Or at least appears to.
{ return this; }
Method to send email (in MainCountActivity.java):
public void sendEmail(String toAddress, String ccAddress, String bccAddress, String subject, String body, String attachmentMimeType) throws Exception{
try {
Intent emailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
emailIntent.setType(attachmentMimeType); //new
String sToAddress[] = { toAddress };
String sCCAddress[] = { ccAddress};
String sBCCAddress[] = { bccAddress };
emailIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
emailIntent.putExtra(Intent.EXTRA_EMAIL, sToAddress);
emailIntent.putExtra(android.content.Intent.EXTRA_CC, sCCAddress);
emailIntent.putExtra(android.content.Intent.EXTRA_BCC, sBCCAddress);
emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
emailIntent.putExtra(Intent.EXTRA_TEXT, body);
//get URI of logfile
File tempFile = new File(Environment.getExternalStorageDirectory () + MainCountActivity.dirPath);
Uri uri = Uri.fromFile(tempFile);
//create URI arraylist and add first URI
ArrayList<Uri> uris = new ArrayList<Uri>();
uris.add(uri);
//get URI of map image and add to arraylist
//make sure it is there to attach
File file = new File(Environment.getExternalStorageDirectory()+"/SensorLocationImages");
do {
downloadFile(getMapLink());
//createDirectoryAndSaveFile(getBitmapFromURL(getMapLink()), "sensorMap.png");
} while (!file.exists());
uris.add(Uri.fromFile(new File(Environment
.getExternalStorageDirectory()
+ "/SensorLocationImages/sensorMap.png")));
//+ "/sdcard/SensorLocationImages/sensorMap.png")));
emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
startActivity(emailIntent);
}
catch(Exception ex) {
ex.printStackTrace();
throw ex;
}
}
OnClick method, for my occasional button issue (In MaincountActivity.java):
public void onClick(View v){
switch(v.getId())
{
case R.id.textView1:
{
break;
}
case R.id.Reset:
{
//allowCounting will let the program know when to let it to count or not, depending if Start or Stop button are pressed.
logCount=0;
mCounter.setText("Total: 0");
mToggle.setChecked(false);
break;
}
/* case R.id.toggleButton:
{
break;
}*/
case R.id.SendEmail:
{
//for debugging purposes:
System.out.println("Email button being clicked!");
LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);
if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER))
{
Toast.makeText(this, "GPS is enabled in your device", Toast.LENGTH_SHORT).show();
try {
sendEmail("","","","Sensor Log Info",getEmailBody(),"multipart/mixed");
} catch (Exception e) {
e.printStackTrace();
}
}
else
{
showGPSAlertForEmail();
}
break;
}
}
Basically, I really want to know why my delete-then-download method has not worked every time. Logcat errors have provided no insight. Thank you for your time.
Hello everyone,
I'm trying to play mp3 audio from a url (radio) using media player class. It is running but it took too much time to start. I know this question is already asked on this site. But I need help. If their is no solution for that kindly tell me alternative method . Reference code or tutorial would be a great help.here is my java code.
public void streaming(String url)
{
MediaPlayer mediaPlayer = new MediaPlayer();
try {
Log.i("stream", "connecting data source");
mediaPlayer.setDataSource(url);
Log.i("stream", "preparing");
mediaPlayer.prepare();
Log.i("stream", "prepared");
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
}
catch(Exception e){
e.printStackTrace();
}
mediaPlayer.start();
Log.i("stream", "Started");
}
}
