I'm not getting Path from image or video from uri that I receive from whatsApp.
Uri comes like this: content://com.whatsapp.provider.media/item/16695
Media coming from Gallery, Downloads ands others are fine.
Anyone know how to get Path? This is the code I'm using:
public String getMediaPath(Context context, Uri uri) {
if (DEBUG)
Log.d(TAG + " File -",
"Authority: " + uri.getAuthority() +
", Fragment: " + uri.getFragment() +
", Port: " + uri.getPort() +
", Query: " + uri.getQuery() +
", Scheme: " + uri.getScheme() +
", Host: " + uri.getHost() +
", Segments: " + uri.getPathSegments().toString()
);
// DocumentProvider
if (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 the remote address
if (isGooglePhotosUri(uri)) {
return uri.getLastPathSegment();
}
return getDataColumn(context, uri, null, null);
}
// File
else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null;
}
public String getDataColumn(Context context, Uri uri, String selection,
String[] selectionArgs) {
Cursor cursor = null;
final String[] column = { MediaStore.Images.Media.DATA };
final String[] projection = {
column[0]
};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs,
null);
if (cursor != null && cursor.moveToFirst()) {
if (DEBUG)
DatabaseUtils.dumpCursor(cursor);
final int index = cursor.getColumnIndexOrThrow(column[0]);
return cursor.getString(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());
}
public static boolean isGooglePhotosUri(Uri uri) {
return "com.google.android.apps.photos.contentprovider".equals(uri.getAuthority());
}
The result of this log:
if (DEBUG)
Log.d(TAG + " File -",
"Authority: " + uri.getAuthority() +
", Fragment: " + uri.getFragment() +
", Port: " + uri.getPort() +
", Query: " + uri.getQuery() +
", Scheme: " + uri.getScheme() +
", Host: " + uri.getHost() +
", Segments: " + uri.getPathSegments().toString()
);
is this:
Authority: com.whatsapp.provider.media, Fragment: null, Port: -1, Query: null, Scheme: content, Host: com.whatsapp.provider.media, Segments: [item, 16348]
And the cursor on getDataColumn looks like this:
>>>>> Dumping cursor
android.content.ContentResolver$CursorWrapperInner@1fc81ac

You can try this it will help for you.You can't get path from WhatsApp directly.If you need an file path first copy file and send new file path. Using the code below
public static String getFilePathFromURI(Context context, Uri contentUri) {
String fileName = getFileName(contentUri);
if (!TextUtils.isEmpty(fileName)) {
File copyFile = new File(TEMP_DIR_PATH + fileName+".jpg");
copy(context, contentUri, copyFile);
return copyFile.getAbsolutePath();
}
return null;
}
public static String getFileName(Uri uri) {
if (uri == null) return null;
String fileName = null;
String path = uri.getPath();
int cut = path.lastIndexOf('/');
if (cut != -1) {
fileName = path.substring(cut + 1);
}
return fileName;
}
public static void copy(Context context, Uri srcUri, File dstFile) {
try {
InputStream inputStream = context.getContentResolver().openInputStream(srcUri);
if (inputStream == null) return;
OutputStream outputStream = new FileOutputStream(dstFile);
IOUtils.copy(inputStream, outputStream);
inputStream.close();
outputStream.close();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
Then IOUtils class is like below
public class IOUtils {
private static final int BUFFER_SIZE = 1024 * 2;
private IOUtils() {
// Utility class.
}
public static int copy(InputStream input, OutputStream output) throws Exception, IOException {
byte[] buffer = new byte[BUFFER_SIZE];
BufferedInputStream in = new BufferedInputStream(input, BUFFER_SIZE);
BufferedOutputStream out = new BufferedOutputStream(output, BUFFER_SIZE);
int count = 0, n = 0;
try {
while ((n = in.read(buffer, 0, BUFFER_SIZE)) != -1) {
out.write(buffer, 0, n);
count += n;
}
out.flush();
} finally {
try {
out.close();
} catch (IOException e) {
Log.e(e.getMessage(), e.toString());
}
try {
in.close();
} catch (IOException e) {
Log.e(e.getMessage(), e.toString());
}
}
return count;
}
}
It works for me for opening small text file... I didn't try in other file
protected void viewhelper(Intent intent) {
Uri a = intent.getData();
if (!a.toString().startsWith("content:")) {
return;
}
//Ok Let's do it
String content = readUri(a);
//do something with this content
}
here is the readUri(Uri uri) method
private String readUri(Uri uri) {
InputStream inputStream = null;
try {
inputStream = getContentResolver().openInputStream(uri);
if (inputStream != null) {
byte[] buffer = new byte[1024];
int result;
String content = "";
while ((result = inputStream.read(buffer)) != -1) {
content = content.concat(new String(buffer, 0, result));
}
return content;
}
} catch (IOException e) {
Log.e("receiver", "IOException when reading uri", e);
} finally {
if (inputStream != null) {
try {
inputStream.close();
} catch (IOException e) {
Log.e("receiver", "IOException when closing stream", e);
}
}
}
return null;
}
I got it from this repository https://github.com/zhutq/android-file-provider-demo/blob/master/FileReceiver/app/src/main/java/com/demo/filereceiver/MainActivity.java
I modified some code so that it work.
Manifest file:
<activity android:name=".MainActivity">
<intent-filter >
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<data android:mimeType="*/*" />
</intent-filter>
</activity>
You need to add
@Override
protected void onCreate(Bundle savedInstanceState) {
/*
* Your OnCreate
*/
Intent intent = getIntent();
String action = intent.getAction();
String type = intent.getType();
//VIEW"
if (Intent.ACTION_VIEW.equals(action) && type != null) {
viewhelper(intent); // Handle text being sent
}
}
Using the code example below will return to you the bitmap :
BitmapFactory.decodeStream(getContentResolver().openInputStream(Uri.parse("content://com.whatsapp.provider.media/item/128752")))
After that you all know what you have to do.
You can't get a path to file from WhatsApp. They don't expose it now. The only thing you can get is InputStream:
InputStream is = getContentResolver().openInputStream(Uri.parse("content://com.whatsapp.provider.media/item/16695"));
Using is you can show a picture from WhatsApp in your app.
protected void onCreate(Bundle savedInstanceState) { /* * Your OnCreate */ Intent intent = getIntent(); String action = intent.getAction(); String type = intent.getType();
//VIEW"
if (Intent.ACTION_VIEW.equals(action) && type != null) {viewhekper(intent);//Handle text being sent}
you can try to this , then you get a bitmap of selected image and then you can easily find it's native path from Device Default Gallery.
Bitmap roughBitmap= null;
try {
// Works with content://, file://, or android.resource:// URIs
InputStream inputStream =
getContentResolver().openInputStream(uri);
roughBitmap= BitmapFactory.decodeStream(inputStream);
// calc exact destination size
Matrix m = new Matrix();
RectF inRect = new RectF(0, 0, roughBitmap.Width, roughBitmap.Height);
RectF outRect = new RectF(0, 0, dstWidth, dstHeight);
m.SetRectToRect(inRect, outRect, Matrix.ScaleToFit.Center);
float[] values = new float[9];
m.GetValues(values);
// resize bitmap if needed
Bitmap resizedBitmap = Bitmap.CreateScaledBitmap(roughBitmap, (int) (roughBitmap.Width * values[0]), (int) (roughBitmap.Height * values[4]), true);
string name = "IMG_" + new Java.Text.SimpleDateFormat("yyyyMMdd_HHmmss").Format(new Java.Util.Date()) + ".png";
var sdCardPath= Environment.GetExternalStoragePublicDirectory("DCIM").AbsolutePath;
Java.IO.File file = new Java.IO.File(sdCardPath);
if (!file.Exists())
{
file.Mkdir();
}
var filePath = System.IO.Path.Combine(sdCardPath, name);
} catch (FileNotFoundException e) {
// Inform the user that things have gone horribly wrong
}
You can also convert the URI to file and then to bytes if you want to upload the photo to your server.
