Required Behaviour: I use following code to save images, and want to show them up in gallery(as we get to see images from whatsapp).
boolean downloadImage(Bitmap image) {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(MainActivity.this, "Download started..", Toast.LENGTH_SHORT).show();
}
});
ContentResolver resolver = getApplicationContext().getContentResolver();
Uri imageCollection;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
imageCollection = MediaStore.Images.Media
.getContentUri(MediaStore.VOLUME_EXTERNAL_PRIMARY);
} else {
imageCollection = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
}
String imgName = "IMG_"+System.currentTimeMillis()+".jpg";
ContentValues imgDetails = new ContentValues();
imgDetails.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");
imgDetails.put(MediaStore.Images.Media.DISPLAY_NAME, imgName);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
imgDetails.put(MediaStore.Images.Media.IS_PENDING, 1);
imgDetails.put(MediaStore.Images.Media.RELATIVE_PATH, "DCIM/DownloaderApp");
}
Uri imgUri = resolver.insert(imageCollection, imgDetails);
try {
OutputStream outputStream = resolver.openOutputStream(imgUri);
boolean saveResult = image.compress(Bitmap.CompressFormat.JPEG, 90, outputStream);
outputStream.close();
imgDetails.clear();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
imgDetails.put(MediaStore.Images.Media.IS_PENDING, 0);
}
resolver.update(imageCollection, imgDetails, null, null);
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(
MainActivity.this,
(saveResult) ?"Image Path: "+imgUri.getPath() :"Failed to save image!",
Toast.LENGTH_SHORT).show();
}
});
outputStream.close();
return saveResult;
} catch(Exception e) {
e.printStackTrace();
return false;
}
}
Current Situation: I can see images getting saved in File Manager at exact location DCIM/DownloaderApp, but these pictures do not appear in gallery, i.e. they are not publically visibe through MediaStore API(what I feel).
Targetted Android: Android 10
I know, I can use android:requestLegacyExternalStorage="true" in manifest. But I want the app to be perfectly compatible with android 11 as well. So don't want to do this.
