Android: Getting A File URI From A Content URI?


Answer :

Just use getContentResolver().openInputStream(uri) to get an InputStream from a URI.

http://developer.android.com/reference/android/content/ContentResolver.html#openInputStream(android.net.Uri)


This is an old answer with deprecated and hacky way of overcoming some specific content resolver pain points. Take it with some huge grains of salt and use the proper openInputStream API if at all possible.

You can use the Content Resolver to get a file:// path from the content:// URI:

String filePath = null; Uri _uri = data.getData(); Log.d("","URI = "+ _uri);                                        if (_uri != null && "content".equals(_uri.getScheme())) {     Cursor cursor = this.getContentResolver().query(_uri, new String[] { android.provider.MediaStore.Images.ImageColumns.DATA }, null, null, null);     cursor.moveToFirst();        filePath = cursor.getString(0);     cursor.close(); } else {     filePath = _uri.getPath(); } Log.d("","Chosen path = "+ filePath);

If you have a content Uri with content://com.externalstorage... you can use this method to get absolute path of a folder or file on Android 19 or above.

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)) {         System.out.println("getPath() uri: " + uri.toString());         System.out.println("getPath() uri authority: " + uri.getAuthority());         System.out.println("getPath() uri path: " + uri.getPath());          // ExternalStorageProvider         if ("com.android.externalstorage.documents".equals(uri.getAuthority())) {             final String docId = DocumentsContract.getDocumentId(uri);             final String[] split = docId.split(":");             final String type = split[0];             System.out.println("getPath() docId: " + docId + ", split: " + split.length + ", type: " + type);              // This is for checking Main Memory             if ("primary".equalsIgnoreCase(type)) {                 if (split.length > 1) {                     return Environment.getExternalStorageDirectory() + "/" + split[1] + "/";                 } else {                     return Environment.getExternalStorageDirectory() + "/";                 }                 // This is for checking SD Card             } else {                 return "storage" + "/" + docId.replace(":", "/");             }          }     }     return null; }

You can check each part of Uri using println. Returned values for my SD card and device main memory are listed below. You can access and delete if file is on memory, but I wasn't able to delete file from SD card using this method, only read or opened image using this absolute path. If you find a solution to delete using this method, please share.

SD CARD

getPath() uri: content://com.android.externalstorage.documents/tree/612E-B7BF%3A/document/612E-B7BF%3A getPath() uri authority: com.android.externalstorage.documents getPath() uri path: /tree/612E-B7BF:/document/612E-B7BF: getPath() docId: 612E-B7BF:, split: 1, type: 612E-B7BF

MAIN MEMORY

getPath() uri: content://com.android.externalstorage.documents/tree/primary%3A/document/primary%3A getPath() uri authority: com.android.externalstorage.documents getPath() uri path: /tree/primary:/document/primary: getPath() docId: primary:, split: 1, type: primary

If you wish to get Uri with file:/// after getting path use

DocumentFile documentFile = DocumentFile.fromFile(new File(path)); documentFile.getUri() // will return a Uri with file Uri

Converting A String To Int In Groovy

Answer : Use the toInteger() method to convert a String to an Integer , e.g. int value = "99".toInteger() An alternative, which avoids using a deprecated method (see below) is int value = "66" as Integer If you need to check whether the String can be converted before performing the conversion, use String number = "66" if (number.isInteger()) { int value = number as Integer } Deprecation Update In recent versions of Groovy one of the toInteger() methods has been deprecated. The following is taken from org.codehaus.groovy.runtime.StringGroovyMethods in Groovy 2.4.4 /** * Parse a CharSequence into an Integer * * @param self a CharSequence * @return an Integer * @since 1.8.2 */ public static Integer toInteger(CharSequence self) { return Integer.valueOf(self.toString().trim()); } /** * @deprecated Use the CharSequence version * @see #toInteger(CharSequence) */ @Deprecated public static Integer toInteger(String self) { return toInteg

"Cannot Create Cache Directory /home//.composer/cache/repo/https---packagist.org/, Or Directory Is Not Writable. Proceeding Without Cache"

Answer : if anyone pass through here, this is shorter solution: sudo chown -R $USER $HOME/.composer it seems to me the group information is missing in your command sudo chown -R <user> /home/<user>/.composer/cache/repo/https---packagist.org Shoud be sudo chown -R <user>:<group> /home/<user>/.composer/cache/repo/https---packagist.org But to avoid other permission issues, I would rather advise: sudo chown -R <user>:<group> /home/<user>/.composer/cache (you'll need access to other folders in there) and sudo chown <user>:<group> /home/<user>/.composer To make sure your user has permissions enough on the global composer folder. Mind the missing recursion so the user don't own keys created by root. If you need to find out the group: groups <user>

Android How Can I Convert A String To A Editable

Answer : As you probably found out, Editable is an interface so you cannot call new Editable() . However an Editable is nothing more than a String with Spannables, so use SpannableStringBuilder: Editable editable = new SpannableStringBuilder("Pass a string here"); If you only want to change the Spannables, never the text itself, you can use a basic SpannableString. Use Editable.Factory.getInstance().newEditable(str) From the android documentation: Returns a new SpannedStringBuilder from the specified CharSequence. You can override this to provide a different kind of Spanned.
