android-mediascanner

问题 Background: In Android 4.4, Google decided that apps should not have write access to SD cards. However, apps can write to /SDCard/Android/data/App Package Name. So this is what I've done. I have written an MP3 file to /Android/data/. I then want this MP3 file to show up in Android music players. I've tried the following... sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://" + filePath))); and.... MediaScannerConnection.scanFile(this, new String[] { file.toString() }, new

问题 My App downloads some mp3 files to sdcard. I want to play them with other music players installed on the device. But the other music players don't automatically find my downloaded files. How can I force the MediaScanner to run so that my media files will be playable from the stock Music application? I download the files using this code public void run() { loaded = 0; try{ java.io.BufferedInputStream in = new java.io.BufferedInputStream(new java.net.URL(url).openStream()); java.io

问题 In my app I store information about an image or an image album by storing it's MediaStore id. Later on I may have to perform operations that require these images/albums. Is the MediaStore id a safe way to keep image\album information? More specifically: 1) If an image/album whose id I have stored gets deleted, is it possible a new picture/album could take this id resulting in me using the wrong picture/album ? 2) when pictures/abums are renamed or moved ( using a file browser on the phone or

问题 I managed to download a file to the local storage but I can't manage to pass it's path to the media scanner so it gets added to the gallery. I've added a plugin that does the media scanner work. The function that tries to do the trick is this one. private boolean mediaScanner(String absolutePath, CallbackContext callbackContext) throws InterruptedException, JSONException { Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE); String path = Uri.parse(absolutePath).getPath

问题 I'm trying to delete some files or directories from the internal memory (ASUS TF101) using the commands File.delete(). However, using the Android File explorer I can see how the files are removed, but using the Windows explorer they still show there. I solved a similar issue when adding files just creating a MediaScannerConection (and using the method scanFile). Does anyone know how to solve this problem? Of course it´s not acceptable to restart the device as the final user will not like this

问题 I have the following code (this is a plugin to save a base64 as an image file on the phone) @Override public boolean execute(String action, JSONArray args, CallbackContext callbackContext) { if (!action.equals("saveImage")) { return false; } try { String b64String = args.getString(0); if (b64String.startsWith("data:image")) { b64String = b64String.substring(b64String.indexOf(',') + 1); } JSONObject params = args.getJSONObject(1); //Optional parameter String filename = params.has("filename") ?

问题 I am currently developing an Android Application where users take pictures which are stored in External Memory on the device then I am trying to also get the Gallery to scan the file to add the new media to the Gallery however this does not seem to update until the device reboots. The code I am using is as follows: Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE); File f = new File(mCurrentPhotoPath); Log.v("INFO", mCurrentPhotoPath.toString()); Uri contentUri = Uri

问题 When I save an image to new location and then use MediaScanner to refresh the gallery then everything is fine - thumbnails and images are refreshed well. But when I save an image to EXISTING location and then use MediaScanner - then only 'new' thumbnail isnt refreshed. (even though file is overwritten). How to solve it? Here is my code : File file = new File(SDCARD_PATH, filename); try { FileOutputStream out = new FileOutputStream(file); bmp.compress(format, BEST_IMAGE_QUALITY, out); }catch

问题 Question: how to make the media store to refresh its entry of a DELETED file? After deleting a photo in code from the external storage, I still see a slot for the deleted photo in the gallery - blank photo. It seems that the gallery reflects the media store and the deleted photo is found in the media store until the phone is restarted or generally - until the media is rescanned. Trying to scan the deleted file did not help scanning deleted files (works just for new or existing files):

问题 When deleting the images on Android’s SD Card, sometime the images are correctly removed but in the gallery still remain a preview of the removed image. When tapping on it, it is loaded as a black image. To resolve it, you need to run MediaScanner. But this code won't work and still the preview of review image remain in the Gallery. Anyone knows how to resolve this. Uri contentUri = Uri.fromFile(file); Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,contentUri);
