I am successfully able to select file programmatically. But, when I am getting uri from that file
content://com.android.providers.downloads.documents/document/3356
content://com.android.providers.downloads.documents/document/3331
Unfortunately, wherever the file is my uri is always locating at downloads.documents
I think it doesn't fact. Cause, everyone get the uri by data.getData(). So, I think the uri is correct.
Last year, I was working with Audio, Video, File and Image uploading to server. I was trying that source code to get path.
String mediaPath, mediaPath1;
String[] mediaColumns = {MediaStore.Video.Media._ID};
// Get the file from data
String path = data.getStringExtra(mediaPath);
File file = new File(path);
Uri selectedFile = Uri.fromFile(new File(file.getAbsolutePath()));
String[] filePathColumn = {MediaStore.Files.FileColumns.MEDIA_TYPE};
Cursor cursor = getContentResolver().query(selectedFile, filePathColumn, null, null, null);
assert cursor != null;
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
mediaPath = cursor.getString(columnIndex);
txt.setText(path);
// Set the Image in ImageView for Previewing the Media
cursor.close();
Unfortunately,That is returning null pointerexception. After researching little bit, I found another source code(PathUtils)
public class PathUtils {
public static String getPath(final Context context, final Uri uri) {
// DocumentProvider
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && DocumentsContract.isDocumentUri(context, uri)) {
if (isExternalStorageDocument(uri)) {// ExternalStorageProvider
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
String storageDefinition;
if("primary".equalsIgnoreCase(type)){
return Environment.getExternalStorageDirectory() + "/" + split[1];
} else {
if(Environment.isExternalStorageRemovable()){
storageDefinition = "EXTERNAL_STORAGE";
} else{
storageDefinition = "SECONDARY_STORAGE";
}
return System.getenv(storageDefinition) + "/" + split[1];
}
} else if (isDownloadsDocument(uri)) {// DownloadsProvider
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);
} else if (isMediaDocument(uri)) {// MediaProvider
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);
}
} else if ("content".equalsIgnoreCase(uri.getScheme())) {// MediaStore (and general)
// Return the remote address
if (isGooglePhotosUri(uri))
return uri.getLastPathSegment();
return getDataColumn(context, uri, null, null);
} else if ("file".equalsIgnoreCase(uri.getScheme())) {// File
return uri.getPath();
}
return null;
}
public static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs) {
Cursor cursor = null;
final String column = "_data";
final String[] projection = {
column
};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs, null);
if (cursor != null && cursor.moveToFirst()) {
final int column_index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(column_index);
}
} finally {
if (cursor != null)
cursor.close();
}
return null;
}
public static boolean isExternalStorageDocument(Uri uri) {
return "com.android.externalstorage.documents".equals(uri.getAuthority());
}
public static boolean isDownloadsDocument(Uri uri) {
return "com.android.providers.downloads.documents".equals(uri.getAuthority());
}
public static boolean isMediaDocument(Uri uri) {
return "com.android.providers.media.documents".equals(uri.getAuthority());
}
public static boolean isGooglePhotosUri(Uri uri) {
return "com.google.android.apps.photos.content".equals(uri.getAuthority());
}
}
I am not getting any error. But, Path is always locating at Downloads file. I don't know why. After looking at uri I noticed my uri is always returning downloads.documents. I am not sure is it the issue.
There is lot of question similar to this question in stackoverflow. To tell everyone none worked for me. So, I will request to not flag it.
