Model: Samsung SM-G900F (Android 5.0)
Code to launch camera:
File file = new File(getExternalFilesDir(null),"video.mp4");
Uri uri = FileProvider.getUriForFile(this, "example.com.myapplication.fileprovider", file);
final Intent takePictureIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
takePictureIntent.addFlags(Intent.FLAG_GRANT_WRITE_URI_PERMISSION| Intent.FLAG_GRANT_READ_URI_PERMISSION);
} else {
final List<ResolveInfo> resInfoList =
getPackageManager()
.queryIntentActivities(takePictureIntent, PackageManager.MATCH_DEFAULT_ONLY);
for (final ResolveInfo resolveInfo : resInfoList) {
final String packageName = resolveInfo.activityInfo.packageName;
grantUriPermission(packageName, uri,
Intent.FLAG_GRANT_WRITE_URI_PERMISSION |
Intent.FLAG_GRANT_READ_URI_PERMISSION);
}
}
startActivityForResult(takePictureIntent, 42);

Looks like video capturing works only with file uri and doesn't work with content uri.
Do you have the same issues? Could you suggest some general solution?
回答1:
This helped me:
Uri uri;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
uri = FileProvider.getUriForFile(context, context.getApplicationContext().getPackageName() + ".provider", f);
} else {
uri = Uri.fromFile(f);
}
intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
回答2:
This is working for me.
private void launchCamera() {
Intent captureVideoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
if (captureVideoIntent.resolveActivity(getPackageManager()) != null)
{
Uri videoUri = null;
try {
videoUri = getOutputMediaFileUri();
} catch (Exception ex) {
// Error occurred while creating the File
ex.printStackTrace();
}
// Continue only if the File was successfully created
if (videoUri != null) {
captureVideoIntent.putExtra(MediaStore.EXTRA_OUTPUT, videoUri);
startActivityForResult(captureVideoIntent, REQUEST_CAMERA);
}
}
}
/**
* Creating file uri to store image/video
*/
private Uri getOutputMediaFileUri() {
if(Build.VERSION.SDK_INT >= 24) {
// For android N you need to use the file provider
return FileProvider.getUriForFile(this, getResources().getString(R.string.file_provider_name), getOutputMediaFile());
} else {
return Uri.fromFile(getOutputMediaFile());
}
}
/**
* returning file to store image / video
*/
private File getOutputMediaFile() {
// External sdcard location
File mediaStorageDir = new File(
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
"DirectoryNameWhereYouWantToStore");
// Create the storage directory if it does not exist
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
Log.d(TAG, "Oops! Failed to create directory");
return null;
}
}
// Create a media file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(new Date());
return new File(mediaStorageDir.getPath() + File.separator + "IMG_" + timeStamp + ".mp4");
}
