Hold the image on the Activity

I use this code to pick an image from the device but when the activity is closed the image disappears. How to save it so whenever I open the Activity the image is still there?
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_LOAD_IMAGE:
if (resultCode == RESULT_OK && data!= null) {
Uri imageData = data.getData() ;
imageView.setImageURI(imageData);
}
}
}

So what you need is save the selected imageUri in local preferences of the activity.
Please check the code below:
public class Prefs {
private static Prefs INSTANCE;
private static SharedPreferences prefs;
public static Prefs getInstance(Context context) {
if (INSTANCE == null) {
INSTANCE = new Prefs();
prefs = context.getSharedPreferences("prefs", Context.MODE_PRIVATE);
}
return INSTANCE;
}
public void setImage(String image) {
prefs.edit().putString("image", image).apply();
}
public String getImage() {
return prefs.getString("image", "");
}
Then in your activity:
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_layout);
if(!TextUtils.isEmpty(Prefs.getInstance(applicationContext).getImage()){
val imgFile = File(Prefs.getInstance(getApl).getImage())
if (imgFile.exists()) {
val myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath())
imageView.setImageBitmap(myBitmap)
}
}
In your onActivityResult:
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case RESULT_LOAD_IMAGE:
if (resultCode == RESULT_OK && data!= null) {
Uri imageData = data.getData() ;
imageView.setImageURI(imageData);
Prefs.getInstance(applicationContext).setImage(PathUtils.getPath(applicationContext,imageData));
}
}
}
public class PathUtils {
public static String getPath(final Context context, final Uri uri) {
// DocumentProvider
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && DocumentsContract.isDocumentUri(context, uri)) {
if (isExternalStorageDocument(uri)) {// ExternalStorageProvider
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
String storageDefinition;
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
} else {
if (Environment.isExternalStorageRemovable()) {
storageDefinition = "EXTERNAL_STORAGE";
} else {
storageDefinition = "SECONDARY_STORAGE";
}
return System.getenv(storageDefinition) + "/" + split[1];
}
} else if (isDownloadsDocument(uri)) {// DownloadsProvider
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);
} else if (isMediaDocument(uri)) {// MediaProvider
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);
}
} else if ("content".equalsIgnoreCase(uri.getScheme())) {// MediaStore (and general)
// Return the remote address
if (isGooglePhotosUri(uri))
return uri.getLastPathSegment();
return getDataColumn(context, uri, null, null);
} else if ("file".equalsIgnoreCase(uri.getScheme())) {// File
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 = {

};
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());

}

first, you must use cursor for catch media path, then you can store on the hawk or shared preferences with a special key. then open the image with data stored in Hawk or shared preferences.
eg :
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
mediaPath = cursor.getString(columnIndex);
Hawk.put("image",mediaPath);
//after_reset =>
String mediaPath1 = Hawk.get("image").toString();
channelImage.setImageBitmap(BitmapFactory.decodeFile(mediaPath1));

Unable to pickup file from SDCARD in Oreo

I am New in Android, Working on one functionality in which I have to pick up a file from internal storage and SDCARD. I have implemented some code. With the help of below code, I am able to pick up or select a file from SDcard and internal storage in the Android pie version(9 API level 28) and Android Nougat version(7) but I am not able to get pdf file in from SDCARD in Android Oreo(8 api level 26) version and for Marshmallow it is unable to select file from internal as well as SDCARD. I am not able to figure out what is the problem. Same code working for one not working for another. There is any universal way to access files(pdf and images).Thanks in advance

Get correct Uri from file chooser with google drive

so here is my problem, i need to get a file in phone and then upload it to my parse-server. I've made a file chooser for document, download, external, media folder but android file chooser also propose GoogleDrive option. So i got te Uri but i can't find a way to access that "local copy?".
Do i need to use GoogleDrive SDK to access it? Or can't android just be smart enough and give me methods to handle that Uri ?
I did success getting file name.

Here is my file chooser and handler:

EDIT :
I've made some try but i got a problem when deleting the temporary file
Here is my code:
public static void copyFile(final Context context, final Uri uri, final ParseObject dataSource, final String field, final String name, final Data.Source target, final Handler handler) {
new AsyncTask<Void, Void, Boolean>() {
#Override
protected Boolean doInBackground(Void... params) {
try {
InputStream inputStream = context.getContentResolver().openInputStream(uri);
if (inputStream != null) {
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
byte[] bytes = new byte[1024];
int length;
while ((length = inputStream.read(bytes)) != -1) {
byteArrayOutputStream.write(bytes, 0, length);
}
dataSource.put(field, new ParseFile(name, byteArrayOutputStream.toByteArray()));
byteArrayOutputStream.close();
inputStream.close();
return true;
} else {
return false;
}
} catch (IOException e) {
e.printStackTrace();
return false;
}
}
#Override
protected void onPostExecute(final Boolean success) {
dataSource.getParseFile(field).saveInBackground(new SaveCallback() {
#Override
public void done(ParseException e) {
if (e == null) {
if (handler != null) {
handler.success();
}
}
}
}, new ProgressCallback() {
#Override
public void done(Integer percentDone) {
if (handler != null) {
handler.progress(percentDone);
}
}
});
}
}.execute();
}
Final Edit:
Here my code is correct, temporary file are created and put in cache by Parse himself, so its out of my range. Hope he can help.

So i got te Uri but i can't find a way to access that "local copy?".
There is no "local copy", at least one that you can access.
Or can't android just be smart enough and give me methods to handle that Uri ?
Use ContentResolver and openInputStream() to get an InputStream on the content identified by the Uri. Either use that directly with your "parse-server", or use it to create a temporary "local copy" to a file that you control. Upload that local copy, deleting it when you are done.
Here is my file chooser and handler:
pick() is fine. upload() might be fine; I have not used Parse. The rest of that code is junk, copied from prior junk. It makes many unfounded, unreliable assumptions, and it will not work for Uri values from arbitrary apps (e.g., served via FileProvider).

Android: All file ain't readable. File finder

i'am trying to make a finder to get '.pdf', i got my Uri the file exist but he always return false for File.canRead()
Just before trying to upload that document on my parse server i log this:
final File file = new File(path);
Log.d("=== TAG ====", file.getAbsolutePath());
Log.d("=== TAG ====", String.valueOf(file.exists()));
Log.d("=== TAG ====", String.valueOf(file.canRead()));
Give me this:
06-27 10:58:03.746 24136-24136/bruce.team D/=== TAG ====: /storage/emulated/0/Download/random.pdf
06-27 10:58:03.747 24136-24136/bruce.team D/=== TAG ====: true
06-27 10:58:03.747 24136-24136/bruce.team D/=== TAG ====: false
Then it's just fail uploading after 15 sec, my parse-server isn't access so it must be the read problem !
Manifest:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
My way to pick it:
public static void pick(final Controller controller) {
final Intent chooseFileIntent = new Intent(Intent.ACTION_GET_CONTENT);
chooseFileIntent.setType("application/pdf");
chooseFileIntent.addCategory(Intent.CATEGORY_OPENABLE);
if (chooseFileIntent.resolveActivity(controller.getContext().getPackageManager()) != null) {
controller.startActivityForResult(chooseFileIntent, Configuration.Request.Code.Pdf.Pdf);
}
}
So my question why canRead always return false ? How can I read it?
EDIT: The way I get my Path that seems good for me.

My on activity result :

final Document document = new Document(Session.User);
document.setCategory(Document.Category.CurriculumVitae);
document.setType("PDF");
document.save(getContext(), fileUri, new Uploader.Handler() {
#Override
public void progress(Integer percentage) {
Log.d("=====", String.valueOf(percentage));
if (isLoading()) {
int progressValue = 0;
progressValue += document.uploaded;
documentProgressBar.setProgress(60 * progressValue);
}
}
#Override

Just maybe you dont have permissions to read the file. The file can be stored with permission that doesnt allow you to read in other applications.

Okey so for everyone who can be in the same situation, just re-check if your application didn't loose permission :/ I'am sad
