Ik heb een app waarmee ik een video vastleg met de camera. Ik kan het bestandspad van de video krijgen, maar ik heb het nodig als een Uri.
Het bestandspad dat ik krijg:
/storage/emulated/0/DCIM/Camera/20141219_133139.mp4
Wat ik nodig heb is als volgt:
content//media/external/video/media/18576.
Dit is mijn code.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// if the result is capturing Image
if (requestCode == CAMERA_CAPTURE_VIDEO_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
// video successfully recorded
// preview the recorded video
// selectedImageUri = data.getData();
// Uri selectedImage = data.getData();
previewVideo();
tv1.setText(String.valueOf((fileUri.getPath())));
String bedroom=String.valueOf((fileUri.getPath()));
Intent i = new Intent();
i.putExtra(bhk1.BEDROOM2, bedroom);
setResult(RESULT_OK,i);
btnRecordVideo.setText("ReTake Video");
} else if (resultCode == RESULT_CANCELED) {
// user cancelled recording
Toast.makeText(getApplicationContext(),
"User cancelled video recording", Toast.LENGTH_SHORT)
.show();
} else {
// failed to record video
Toast.makeText(getApplicationContext(),
"Sorry! Failed to record video", Toast.LENGTH_SHORT)
.show();
}
}
}
Ik heb een Uri nodig van de String-variabele bedroom.

Probeer de volgende code
Uri.fromFile(new File("/sdcard/sample.jpg"))

Normaal antwoord op deze vraag als je echt iets wilt krijgen als content//media/external/video/media/18576(bijvoorbeeld voor je video mp4 absolute pad) en niet alleen file///storage/emulated/0/DCIM/Camera/20141219_133139.mp4:
MediaScannerConnection.scanFile(this,
new String[] { file.getAbsolutePath() }, null,
new MediaScannerConnection.OnScanCompletedListener() {
public void onScanCompleted(String path, Uri uri) {
Log.i("onScanCompleted", uri.getPath());
}
});
Geaccepteerd antwoord is fout (omdat het content//media/external/video/media/*niet retourneert)
Uri.fromFile(file).toString()retourneert alleen iets als file///storage/emulated/0/*wat een eenvoudig absoluut pad is van een bestand op de sdcard maar met file//prefix (schema)
U kunt ook contenturi krijgen met behulp van de MediaStore-database van Android
TEST(wat Uri.fromFileretourneert en wat MediaScannerConnectionretourneert):
File videoFile = new File("/storage/emulated/0/video.mp4");
Log.i(TAG, Uri.fromFile(videoFile).toString());
MediaScannerConnection.scanFile(this, new String[] { videoFile.getAbsolutePath() }, null,
(path, uri) -> Log.i(TAG, uri.toString()));
Uitvoer:
I/Test: file:///storage/emulated/0/video.mp4
I/Test: content://media/external/video/media/268927

Als u het Uri-pad van String File-pad wilt ophalen, werkt deze code ook in AndroidQ.
String outputFile = context.getExternalFilesDir("DirName") + "/fileName.extension";
File file = new File(outputFile);
Log.e("OutPutFile",outputFile);
Uri uri = FileProvider.getUriForFile(Activity.this,
BuildConfig.APPLICATION_ID + ".provider",file);
declareer provider in applicatie Tag manifest
<provider
android:name="androidx.core.content.FileProvider"
android:authorities="${applicationId}.provider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/provider_paths" />
</provider>
onder res -> xml ->provider_paths.xml
<paths>
<external-path name="external_files" path="."/>
</paths>

Onderstaande code werkt prima voor 18 API:-
public String getRealPathFromURI(Uri contentUri) {
// can post image
String [] proj={MediaStore.Images.Media.DATA};
Cursor cursor = managedQuery( contentUri,
proj, // Which columns to return
null, // WHERE clause; which rows to return (all rows)
null, // WHERE clause selection arguments (none)
null); // Order-by clause (ascending by name)
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
hieronder code gebruiken op kitkat:-
public static String getPath(final Context context, final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
// DocumentProvider
if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
// ExternalStorageProvider
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
}
// TODO handle non-primary volumes
}
// DownloadsProvider
else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);
final Uri contentUri = ContentUris.withAppendedId(
Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
return getDataColumn(context, contentUri, null, null);
}
// MediaProvider
else if (isMediaDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
Uri contentUri = null;
if ("image".equals(type)) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if ("video".equals(type)) {
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
} else if ("audio".equals(type)) {
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
}
final String selection = "_id=?";
final String[] selectionArgs = new String[] {
split[1]
};
return getDataColumn(context, contentUri, selection, selectionArgs);
}
}
// MediaStore (and general)
else if ("content".equalsIgnoreCase(uri.getScheme())) {
return getDataColumn(context, uri, null, null);
}
// File
else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null;
}
