Hold the image on the Activity

Hold the image on the Activity - android

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 = {
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());
}
public static boolean isGooglePhotosUri(Uri uri) {
return "com.google.android.apps.photos.content".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));

How to get absolute PATH from Uri picked from Downloads folder? [duplicate]

This question already has answers here:

Android - Get real path of a .txt file selected from the file explorer

Closed 1 year ago.
I want to get absolute path by Uri, when picking some files from Downloads folder. API level 21+.
Currently I have such errors:
Input Uri: content://com.android.providers.downloads.documents/document/1603
Path: content://downloads/public_downloads/1603
Giving error: java.lang.IllegalArgumentException: Unknown URI: content://downloads/public_downloads/1603
or this one:
java.io.FileNotFoundException: /document/msf:64020: open failed: ENOENT (No such file or directory)
java.lang.NumberFormatException: For input string: "msf:64020"
depending on how I access such files. How can I do that properly? Maby you can provide some usuful link to documentation. Thanks.

But it always returns null.

Camera intent issue with different phones android

I am calling camera intent to capture an image and get the image uri in onActivtyResult in my fragment.
this is my captureImage()
private void captureImage() {
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(intent, REQUEST_CAMERA_STORAGE);
}
this is my onActivityResult in fragment
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_CAMERA_STORAGE && resultCode == RESULT_OK) {
Uri targetUri = data.getData();
String imagePath;
if (data.toString().contains(AppConstants.CONTENT)) {
imagePath = getRealPathFromURI(targetUri);
} else if (data.toString().contains(AppConstants.CONTENT)) {
imagePath = targetUri.getPath();
} else {
imagePath = null;
}
Log.d("imageuri",imagePath);
}
this getRealPathFromUri()
public String getRealPathFromURI(Uri uri) {
Cursor cursor = null;
try {
String[] proj = {MediaStore.Images.Media.DATA};
cursor = context.getContentResolver().query(uri, 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();
}
}
}
this works fine in one phone and in some phones, in onActivityResult data.getData() returns null.
to resolve this i came across this Capture Image from Camera and Display in Activity
but here it returns a thumbnail image.
So is there any work around to get the captured image uri from camera.

Try This
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
mImageView.setImageBitmap(imageBitmap);
}
}

Try this in onActivityResult()
Uri imageUri = data.getData ();
and then you can set it to imageview

How to get an image from the gallery, get its name, save it in the internal memory and get the route of that image

(I apologize if I make mistakes writing in English)
I need to do the same as the title says
I only know how to get the image from the gallery. I think this is correct:
(If it is wrong or it is inefficient please let me know)
private final int SELECT_PICTURE = 200;
btnAddImage.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent galeryIntent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
galeryIntent.setType("image/*");
startActivityForResult(galeryIntent.createChooser(galeryIntent, "Sececiona Imagen"), SELECT_PICTURE);
}
});
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode){
case (SELECT_PICTURE):
if(requestCode == RESULT_OK){
Uri path = data.getData();
}
}
break;
}
}
But I don't know how to get the name of the image that I caught from the gallery and save it whit that name in the internal memory of my app.
Then I need the route of the image like "MyAPP/media/ ..." , I don't know the correct name in English for that, and save it in my database (save it in my database is easy) and then use it in my project
I know this is a long message but I need your help because in the Spanish forum of StackOverflow anybody answered me.
