Android 11
targetApi 30
do not request READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE
use SAF api to get a uri like this:
"content://com.android.providers.media.documents/document/document%3"
and parse the uri like this:
public static String getRealPath(uri) {
String docId = DocumentsContract.getDocumentId(uri);
String[] split = docId.split(":");
String type = split[0];
Uri contentUri;
switch (type) {
case "image":
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
break;
case "video":
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
break;
case "audio":
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
break;
default:
contentUri = MediaStore.Files.getContentUri("external");
}
String selection = "_id=?";
String[] selectionArgs = new String[]{
split[1]
};
return getDataColumn(getContext(), contentUri, selection, selectionArgs);
}
public static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs) {
Cursor cursor = null;
String column = "_data";
String[] projection = {
column
};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs, null);
if (cursor != null && cursor.moveToFirst()) {
int column_index = cursor.getColumnIndexOrThrow(column);
String value = cursor.getString(column_index);
if (value.startsWith("content://") || !value.startsWith("/") && !value.startsWith("file://")) {
return null;
}
return value;
}
} catch (Exception e) {
e.printStackTrace();
} finally {
if (cursor != null) {
cursor.close();
}
}
return null;
}
and I get normal value on mobile phones below android 11, but empty value on android 11 mobile phones
Well, I want to get the file's real path or name
Can someone help me？
Thanks!
