Android: Get real path from uri
I want to generate a file to the server and I need to get the real path from the uri.
My code:
public String getPathFromURI(Context context, Uri contentUri) {
if ( contentUri.toString().indexOf("file:///") > -1 ){
return contentUri.getPath();
}
Cursor cursor = null;
try {
String[] proj = { MediaStore.Images.Media.DATA };
cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}finally {
if (cursor != null) {
cursor.close();
}
}
}
And onActivityResult:
... imageName = data.getData(); imagePath = getPathFromURI(getBaseContext(),imageName); Picasso.with(getBaseContext()).load(imageName).into(imageView); ...
How is it possible that the image is displayed in the ImageView, but the imagePath is ALWAYS empty? :) Thanks
EDIT:
How to send an image to the server
HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpPost httpPost = new HttpPost([URL TO A SERVER]);
MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);
entity.addPart("uploaded_file_1", new FileBody(new File( imagePath )));
httpPost.setEntity(entity);
httpClient.execute(httpPost, localContext);

I went through several stack answers and found a solution ...
public static String getPathFromURI(final Context context, final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
// DocumentProvider
if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
// ExternalStorageProvider
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
}
}
// DownloadsProvider
else if (isDownloadsDocument(uri)) {
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);
}
// MediaProvider
else if (isMediaDocument(uri)) {
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);
}
}
// MediaStore (and general)
else if ("content".equalsIgnoreCase(uri.getScheme())) {
return getDataColumn(context, uri, null, null);
}
// File
else if ("file".equalsIgnoreCase(uri.getScheme())) {
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());
}
This will find the real path in every case even for kitkat (that was the problem ... kitkat)

here is my simple code ... it will work 100% and for android version> 23
and if you get an error when selecting an image from the gallery it is recommended
public String getPathFromUri(Uri uri, Activity activity) {
String[] projection = {MediaStore.MediaColumns.DATA};
Cursor cursor = activity.managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}

I couldn't find a way to share media over the phone from Marshmallow from Google Photos to my app. I will try to explain why this is happening.
I have not found any official documentation to substantiate my thoughts, but I will share them with you to see if we can find a solution through the collaboration of different people.
My theory is that Google Photos does not physically have media on the phone, they are probably thumbnails or online. So when you share some photos, they are uploaded temporarily and are probably stored in the internal storage of the app, so you cannot access them (along the way).
The only workaround I've found to get the file path is to copy it to my app's internal storage. I don't like it, but everything I tried didn't work for me.
