My app allows users to take a picture with the camera and saves it to a custom folder. This works fine. The issue being seen by users (Samsung devices) is that the Gallery app crashes when launched. The only way to fix this is to go into Pictures folder on the device and remove the myApp custom directory.
Has anybody seen this issue before? I can paste the image creation/saving code if needed but that is working just fine.
Is this a permissions issue?
Could this be the issue?
You can try update system according to system version:
File mediaStorageDir = new File(getPictureDirectory());
Uri contentUri = Uri.fromFile(mediaStorageDir);
if(Build.VERSION.SDK_INT >= 19){
Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
mediaScanIntent.setData(contentUri);
getApplication().sendBroadcast(mediaScanIntent);
}else{
getApplication().sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, contentUri));
}
It works for me. Hope it help!

I am new to android development.
I am trying to open the default gallery app to view an image like this:
Uri u = Uri.parse((String) gridView.getAdapter().getItem(position);
Intent i = new Intent();
i.setDataAndType(u, "image/*");
i.setAction(Intent.ACTION_VIEW);
i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivity(i);
I provide the file paths to my images like this:
/storage/emulated/0/WhatsApp/Media/WhatsApp Images/IMG-20191023-WA0045.jpg
/storage/emulated/0/Pictures/9GAG/1565987862000.jpg
My App and Google Photos can display the image given this path, the Samsung Gallery( tested on Android Oreo) or the Xiaomi Gallery App (tested on Android X) can't find the image; also if i try to add "content://" or "file://" at the beginning.
I suspect that the apps want to have a Content URI or some kind of symbolic link without the "/storage/emulated/0/" part instead of a File URI. I searched for methods to get the content URI out of the file path, but didn't find any examples for Android X.
So what is the correct URI to pass on through the Intent and how do i get it?
Or maybe somebody knows a better way to just open the gallery app to a specific picture i provide by an absolute file path (Both External Storage and SD Card)?
Thank you in advance and greetings!
copied from this question here , this might work for you
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("content://media/external/images/media/16"))); /** replace with your own uri */
I am very new to Android development!
I am working on a camera-related app, and I encountered a problem that the pictures taken are not immediately displayed in 'Photos' app in Android 5.0.1, but when I restart the phone, and take a picture one more time, the previous pictures would all be displayed in 'Photos' app. And this problem only occurs in Android 5.0.1. I tried it on Android 4.3, and there isn't the problem.
And I do add the following codes in my program:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Intent mediaScanIntent = new Intent(
Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri contentUri = Uri.fromFile(new File("file://" + Environment.getExternalStorageDirectory() + "/DCIM")); //out is your output file
mediaScanIntent.setData(contentUri);
sendBroadcast(mediaScanIntent);
}
Could anybody help me out there please????
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.fromFile(f);
mediaScanIntent.setData(contentUri);
this.sendBroadcast(mediaScanIntent);
After taking a picture with my app I can verify it exists using a file manager app on the device and also Logging the file path it appears to be correct before passing it to Media Scanner
file:/storage/emulated/0/Pictures/JPEG_20140712_163043_1418054327.jpg
Thanks Aaron
I managed to solve this. The issue was due to, where I setup the mCurrentPhotoPath. So I updated the code to use
photoFile = createImageFile();
mCurrentPhotoPath = photoFile.getAbsolutePath();
Media Scanner take some to scan and insert show results after calling sendBroadcast you can use MediaScannerConnection method onScanCompleted
and then check image in gallery.

Note- even though im using phonegap, the question is not about some issue in that.
Hi, im developing a android app. my app is using phonegap 1.3.
mi problem...
Im using phonegap apis to take a picture and display it in my app. But whats happening is due to some reason the os kills my app after the camera is launched, so that after the photo is clicked, my app is relaunched and it doesnt get the info abt the taken picture.
As a workaround to this problem (the problem), i designed a phonegap plugin which on app start checks if the app had crashed while taking a picture (some flags in code), and if it is restarting after crash, it retrieves the Pic.jpg taken by the camera and tries to displays it. The problem is that its not able to get the right image, or even a proper .jpg file for that matter.
mi code...
Phonegap makes an intent to start the camera and passes the uri for the Pic.jpg that it creates into that intent which it passes to startActivityForResult.
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
File photo = new File(DirectoryManager.getTempDirectoryPath(ctx), "Pic.jpg");
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo));
this.imageUri = Uri.fromFile(photo);
this.ctx.startActivityForResult((Plugin) this, intent, 0);
Note- The above code is from the file CameraLauncher.java of Phonegap.
Now, im assuming that the startActivityForResult stores the picture the user captures at the file which was created by 'photo' in the above code. So even if after the os closes the app while the camera is open (refer - the problem) the photo will be stored there. PLEASE correct me if this assumption is wrong, or if the photo might be being saved somewhere else.
So taking into account this assumption i wrote a plugin which retrieves this image using the same logic which Phonegap uses in CameraLauncher.java
Uri imageUri;
ExifHelper exif = new ExifHelper();
exif.createInFile(getTempDirectoryPath(ctx) + "/Pic.jpg");
exif.readExifData();
File photo = new File(getTempDirectoryPath(ctx), "Pic.jpg");
imageUri = Uri.fromFile(photo);
Bitmap bitmap = null;
bitmap = android.provider.MediaStore.Images.Media.getBitmap(this.ctx.getContentResolver(), imageUri);
ContentValues values = new ContentValues();
values.put(android.provider.MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
Uri uri = null;
try {
uri = this.ctx.getContentResolver().insert(android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
} catch (UnsupportedOperationException e) {
uri = this.ctx.getContentResolver().insert(android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI, values);
}
// Add compressed version of captured image to returned media store Uri
OutputStream os = this.ctx.getContentResolver().openOutputStream(uri);
bitmap.compress(Bitmap.CompressFormat.JPEG, 20, os);
os.close();
exif.createOutFile(getRealPathFromURI(uri, this.ctx));
exif.writeExifData();
bitmap.recycle();
bitmap = null;
System.gc();
result = new PluginResult(Status.OK, uri.toString());
This is roughly the same logic as Phonegap uses. (I've removed all exception handling n all for posting. So assume there are no compile errors n all.) So, im basically trying to retrieve the Pic.jpg and return it to my phonegap app. BUT whats happening is that im getting a corrupted file of abt 150kb that isn't even a jpg (doesnt open).
Please tell me if its even possible to retrieve images in this manner after the activity that started the camera as died. And if its possible then, what am i doing wrong. Please help!
As I mentioned over in your other SO question,
phonegap android app crashing due to low memory on opening camera
the problem is most probably the Sony implementation of the camera intent. You should try testing by adding a third party camera app and when you take a picture select that app and see if it still crashes. It probably won't.
The issue here was because of some changed code in the FileTransfer plugin of Phonegap.
I was able to retrieve an image taken by the camera, after my app restarted after the crash using the above code only. :)
I am trying to open a jpg image file in gallery. This gives a error. I am using the code below
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.parse("/mnt/sdcard/image123.jpg"),"image/jpeg");
startActivityForResult(intent, 900);
This gives a option to open file in gallery. I select Gallery from the list. But it does not open up. I use ASTRO file manager and open the same image file. It opens up fine now. Please let me know if something is wrong.
Where do you got /mnt/sdcard. Try Environment.getExternalStorageDirectory().getAbsolutePath() instead.
Specified Image Path? You can't. Please Refer My Question as How to access different File Manager specific path. Refer this link and then you got a answer.
