What I am trying to do:
I am downloading the image from a url and then trying to share the same. To
achieve this I need the Uri, which I am obtaining by saving the image in
MediaStore.Images.Media.
Code Snippet:
A. Obtained downloaded image
//this is returned from onPostExecute method of an asyntask
public void processDownloadedImage(Bitmap bitmap) {
if (bitmap == null) {
Toast.makeText(this,"Image could not be downloaded and
shared!",Toast.LENGTH_LONG).show();
}
else {
downloadedImage = bitmap;
checkPermissionShowShareSheet();
}
}
B. Checking permission for Marshmallow and higher
public void checkPermissionShowShareSheet() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!Settings.System.canWrite(this)){
requestPermissions(new
String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,
Manifest.permission.READ_EXTERNAL_STORAGE},2909);
}
else {
updateImageUri(downloadedImage);
showShareSheet(downloadedImageUri);
}
}
else {
updateImageUri(downloadedImage);
showShareSheet(downloadedImageUri);
}
}
C. Obtaining image Uri
private void updateImageUri(Bitmap inImage){
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
fixMediaDir();
String path =
MediaStore.Images.Media.insertImage(this.getContentResolver(), inImage,
"SomeImage", null);
storePathInSharedPreferences(path);
Uri uri = Uri.parse(path);
downloadedImageUri = uri;
}
void fixMediaDir() {
File sdcard = Environment.getExternalStorageDirectory();
if (sdcard != null) {
File mediaDir = new File(sdcard, "DCIM/Camera");
if (!mediaDir.exists()) {
mediaDir.mkdirs();
}
}
}
D. Manifest file uses permissions
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission
android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission
android:name="android.permission.READ_EXTERNAL_STORAGE" />
Problem: value returned from below line is null
String path =
MediaStore.Images.Media.insertImage(this.getContentResolver(), inImage,
"SomeImage", null);
Any ideas?
