How can change image saving location i have created the folder but how to save image in it. all downloaded images are saved in pictures folder
#Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
ContentResolver r = contentResolverWeakReference.get();
AlertDialog alertDialog = alertDialogWeakReference.get();
if (r != null)
file = new File(Environment.getExternalStorageDirectory().getPath() + "/CreativeGraphy");
if (!file.exists()) {
file.mkdir();
}
try {
file.createNewFile();
MediaStore.Images.Media.insertImage(r, bitmap, name, desc);
} catch (Exception e) {
e.printStackTrace();
}
alertDialog.dismiss();
Toast.makeText(context, "Download succeed ", Toast.LENGTH_SHORT).show();
}
Use this method
public static void saveBitmap(String path, Bitmap bitmap) {
FileOutputStream out = null;
try {
out = new FileOutputStream(path);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (out != null) {
out.close();
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
After saving you can call scanFile method to index your file in the gallery.
MediaScannerConnection.scanFile(context, new String[]{path}, null, null);
thanks everyone This works
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
ContentResolver r = contentResolverWeakReference.get();
AlertDialog alertDialog = alertDialogWeakReference.get();
if (r != null)
file_path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/CreativeGraphy";
File dir = new File(file_path);
if (!dir.exists()) {
dir.mkdir();
}
File file = new File(dir,name );
FileOutputStream fOut;
try {
MediaStore.Images.Media.insertImage(r, bitmap, name, desc);
fOut = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
} catch (Exception e) {
e.printStackTrace();
}
alertDialog.dismiss();
Toast.makeText(context, "Download succeed ", Toast.LENGTH_SHORT).show();
}

Im trying to save a bitmap as a file however its failing for some reason
Thats the error I keep getting, it only pops up on 5.0 however I tested it on 6.0 sdk and its working fine
java.io.FileNotFoundException: /storage/sdcard/Pictures/mFile/image1491238127.jpg: open failed: EISDIR (Is a directory)

As I observe on your code I found you creating file.mkdir(); it means you creating a new file not get u need to write the code after try catch return exception.
try {
//it gets file path
file = new File(path);
return Compressor.getDefault(getContext()).compressToFile(file);
}catch (Exception e){
return file;
}
ting the exist file..
So I implement picasso, so I can download images and save them on sd cart, so when I want i can use them on the program.
I have a for loop:
for (int i = 0; i < listaProdutos.size(); i++) {
caminho =listaProdutos.get(i).getImagem();
Picasso.with(getApplicationContext()).load("URL"+listaProdutos.get(i).getImagem()).into(target);
}
But I just get into target once and its the last one of for loop,
target code:
private Target target = new Target() {
#Override
public void onBitmapLoaded(final Bitmap bitmap, Picasso.LoadedFrom from) {
//new Thread(new Runnable() {
//#Override
//public void run() {
/*
File file = new File(Environment.getExternalStorageDirectory().getAbsoluteFile(),caminho);
try
{
file.createNewFile();
FileOutputStream ostream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 75, ostream);
ostream.close();
}
catch (Exception e)
{
e.printStackTrace();
}*/
try {
verifyStoragePermissions(AtividadePrincipal.this);
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/imagensDaApp");
myDir = new File(myDir, caminho);
if (!myDir.exists()) {
myDir.getParentFile().mkdirs();
//myDir.createNewFile();
}
FileOutputStream out = null;
out = new FileOutputStream(myDir);
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
//}
//}).start();
}
#Override
public void onBitmapFailed(Drawable errorDrawable) {
}
#Override
public void onPrepareLoad(Drawable placeHolderDrawable) {
if (placeHolderDrawable != null) {
}
}
};
I commented the thread because it does the same thing with or without, if you want you cant uncomment.
I have alredy search about it, but i couldnt find any answer for this problem, all the URL are ok!
I have been been doing this for 3 days, and it keep the same.
YES listaProdutos.size() = 4;
AND all the url are ok!
If u didnt understand the question, please say.
Why not use the following code? No Targets are used here, so no target is getting gc'ed
I took the freedom to optimize your code a little as well. I've done this without testing the code, but it should work without any problems.
new Thread(new Runnable(){
#Override
public void run(){
for (int i = 0; i < listaProdutos.size(); i++) {
caminho =listaProdutos.get(i).getImagem();
try {
verifyStoragePermissions(AtividadePrincipal.this);
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/imagensDaApp");
myDir = new File(myDir, caminho);
if (!myDir.exists()) {
if(myDir.getParentFile().mkdirs()){
//myDir.createNewFile();
FileOutputStream out = null;
out = new FileOutputStream(myDir);
Picasso.with(getApplicationContext()).load("URL"+listaProdutos.get(i).getImagem()).get().compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
}
}
} catch (FileNotFoundException e){
e.printStackTrace();
}catch{IOException e) {
e.printStackTrace();
}
}
}
}).start();
You can create a class implementingTarget:
class MyTarget implements Target {
String name;
public MyTarget(String name) {
this.name = name;
}
#Override
public void onBitmapLoaded(final Bitmap bitmap, Picasso.LoadedFrom from) {
//new Thread(new Runnable() {
//#Override
//public void run() {
/*
File file = new File(Environment.getExternalStorageDirectory().getAbsoluteFile(),caminho);
try
{
file.createNewFile();
FileOutputStream ostream = new FileOutputStream(file);
bitmap.compress(Bitmap.CompressFormat.JPEG, 75, ostream);
ostream.close();
}
catch (Exception e)
{
e.printStackTrace();
}*/
try {
verifyStoragePermissions(AtividadePrincipal.this);
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/imagensDaApp");
myDir = new File(myDir, name);
if (!myDir.exists()) {
myDir.getParentFile().mkdirs();
//myDir.createNewFile();
}
FileOutputStream out = null;
out = new FileOutputStream(myDir);
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
//}
//}).start();
}
#Override
public void onBitmapFailed(Drawable errorDrawable) {
}
#Override
public void onPrepareLoad(Drawable placeHolderDrawable) {
if (placeHolderDrawable != null) {
}
}
};
And use it inside the cycle:
for (int i = 0; i < listaProdutos.size(); i++) {
caminho =listaProdutos.get(i).getImagem();
Picasso.with(getApplicationContext()).load("URL"+listaProdutos.get(i).getImagem()).into(new MyTarget(caminho ));
}
I'm using this code to save images in the SD card (simulated or real) but all the testers of my app are telling me that the have a new folder in their Photos app with all my images (I don't know why on my Nexus 4 with KK this is not happening).
static public void storeImage(Bitmap image, String imgName) {
String root = Environment.getExternalStorageDirectory().toString();
File myRoot = new File(root + "/files");
if (!myRoot.exists()) {
myRoot.mkdir();
}
File myDir = new File(root + "/images/");
if (!myDir.exists()) {
myDir.mkdir();
}
File file = new File(BasePathToFile(imgName));
if (file.exists()) {
file.delete();
}
try {
file.createNewFile();
FileOutputStream out = new FileOutputStream(file);
image.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
Is it possible to change de visibility, security or something to avoid that the Photos App or any App get access to my folder??
After reading a lot I have found this in the android dev page.
So at the end if you want that your files remain private you have to store them in the device.
So I have change my code to this:
static public void storeImage(Bitmap image, String imgName, Context context) {
File file = new File(context.getFilesDir(), imgName);
if (file.exists()) {
if (file.delete()) {
createFile(image, file);
}
} else {
createFile(image, file);
}
}
static public void createFile(Bitmap image, File file) {
try {
if (file.createNewFile()) {
FileOutputStream out = new FileOutputStream(file);
image.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}
I hope this will be useful to someone.
Happy coding.
A #Sebastian pointed getExternalFilesDir(String type) is a more complete solution so i have changed de code to this:
private static Boolean SdMemoryExist() {
return android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED);
}
static public String BasePath(Context context) {
String _basePathToCheck;
if (SdMemoryExist()) {
_basePathToCheck = context.getExternalFilesDir(null).toString() + File.separator;
} else {
_basePathToCheck = context.getFilesDir().toString() + File.separator;
}
return _basePathToCheck;
}
static public void storeImage(Bitmap image, String imgName, Context context) {
File file = new File(BasePath(context), imgName);
if (file.exists()) {
if (file.delete()) {
createFile(image, file);
}
} else {
createFile(image, file);
}
}
static public void createFile(Bitmap image, File file) {
try {
if (file.createNewFile()) {
FileOutputStream out = new FileOutputStream(file);
image.compress(Bitmap.CompressFormat.PNG, 100, out);
out.flush();
out.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}
Happy coding.
i have a imageview , i am trying to save bitmap from imageview by this method
bmp.compress(Bitmap.CompressFormat.PNG, 100, fos);
fos.close();
the rgb of saved image is not like that it looks in running app,so i am wondering if there is any way to save image view directly to a sd card rather getting the bitmap and then save it to sd card.
please help me i have tried everything.
You can read and write object using below code :
public static void witeObjectToFile(Context context, Object object, String filename)
{
ObjectOutputStream objectOut = null;
try
{
FileOutputStream fileOut = context.openFileOutput(filename, Activity.MODE_PRIVATE);
objectOut = new ObjectOutputStream(fileOut);
objectOut.writeObject(object);
fileOut.getFD().sync();
} catch (IOException e)
{
e.printStackTrace();
} finally
{
if (objectOut != null)
{
try
{
objectOut.close();
} catch (IOException e)
{
// do nowt
}
}
}
}
public static Object readObjectFromFile(Context context, String filename)
{
ObjectInputStream objectIn = null;
Object object = null;
try
{
FileInputStream fileIn = context.getApplicationContext().openFileInput(filename);
objectIn = new ObjectInputStream(fileIn);
object = objectIn.readObject();
} catch (FileNotFoundException e)
{
// Do nothing
} catch (IOException e)
{
e.printStackTrace();
} catch (ClassNotFoundException e)
{
e.printStackTrace();
} finally
{
if (objectIn != null)
{
try
{
objectIn.close();
} catch (IOException e)
{
// do nowt
}
}
}
return object;
}
For example ArrayList can be saved as :
ImageView abcImage = (ImageView) readObjectFromFile(context, AppConstants.FILE_PATH_TO_DATA);
and write as :
witeObjectToFile(context, abcImage, AppConstants.FILE_PATH_TO_DATA);
Try to use this
public void onClick(View v) {
if (v.getId() == R.id.btnSaveImage) {
imageView.setDrawingCacheEnabled(true);
Bitmap bm = imageView.getDrawingCache();
storeImage(bm);
}
}
private boolean storeImage(Bitmap imageData) {
// get path to external storage (SD card)
String iconsStoragePath = Environment.getExternalStorageDirectory() + "/yourappname/";
File sdIconStorageDir = new File(iconsStoragePath);
// create storage directories, if they don't exist
sdIconStorageDir.mkdirs();
try {
File file = new File(sdIconStorageDir.toString() + File.separator + "fileName");
FileOutputStream fileOutputStream = new FileOutputStream(file);
BufferedOutputStream bos = new BufferedOutputStream(fileOutputStream);
imageData.compress(CompressFormat.PNG, 100, bos);
bos.flush();
bos.close();
MediaScannerConnection.scanFile(this, new String[] { file.getPath() },
new String[] { "image/jpeg" }, null);
Toast.makeText(this, "Snapshot Saved to " + file, Toast.LENGTH_SHORT).show();
} catch (FileNotFoundException e) {
return false;
} catch (IOException e) {
return false;
}
return true;
}
i have bitmap image when return result and then i want to save it in Photo Art Camera folder in SD card but it is not saved. it shows the toast "Photo Not Saved Sucessfully".
This is the code:
mSave.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
File cacheDir;
Bitmap bitmap = result;
// String path = Environment.getExternalStorageDirectory().toString();
OutputStream fOut = null;
Date d = new Date();
if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED)) {
cacheDir = new File(android.os.Environment.getExternalStorageDirectory(), "Photo Art Camera");
} else { cacheDir = MainActivity.this.getCacheDir(); }
if (!cacheDir.exists()) { cacheDir.mkdirs(); }
File file = new File(cacheDir, "PhotoMarge" + d.getTime() + ".jpg");
try {
fOut = new FileOutputStream(file);
bitmap.compress(CompressFormat.PNG, 150, fOut);
// getImageBitmap(myurl).compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
Toast.makeText(MainActivity.this, "Photo Saved Sucessfully", 500).show();
// mDialog.dismiss();
// MediaStore.Images.Media.insertImage(getContentResolver(),file.getAbsolutePath(),file.getName(),file.getName());
}
catch (FileNotFoundException e) { e.printStackTrace(); }
catch (Exception e) {
e.printStackTrace();
Toast.makeText(MainActivity.this, "Photo Not Saved Sucessfully", 500).show();
}
}
});
i removed my misstake from code .Actually i am saving another bitmap instead saving and converting framelayout bitmap
File cacheDir;
frame.setDrawingCacheEnabled(true);
icon = Bitmap.createBitmap(frame.getDrawingCache());
Bitmap bitmap = icon;
// String path = Environment.getExternalStorageDirectory().toString();
OutputStream fOut = null;
Date d=new Date();
if (android.os.Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED))
cacheDir=new File(android.os.Environment.getExternalStorageDirectory(),"Photo Art Camera");
else
cacheDir=MainActivity.this.getCacheDir();
if(!cacheDir.exists())
cacheDir.mkdirs();
File file = new File(cacheDir, "PhotoMarge"+d.getTime()+".jpg");
try {
fOut = new FileOutputStream(file);
bitmap.compress(CompressFormat.PNG, 100, fOut);
//getImageBitmap(myurl).compress(Bitmap.CompressFormat.JPEG, 85, fOut);
fOut.flush();
fOut.close();
count();
Toast.makeText(MainActivity.this, "Photo Saved Sucessfully", 500).show();
// mDialog.dismiss();
//MediaStore.Images.Media.insertImage(getContentResolver(),file.getAbsolutePath(),file.getName(),file.getName());
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
Toast.makeText(MainActivity.this, "Photo Not Saved Sucessfully", 500).show();
}
}
});
you are compressing it with different argument make it to 100 or 120 it should work..
OutputStream fOut = new FileOutputStream(output);
merged.compress(Bitmap.CompressFormat.JPEG, 100, fOut);
fOut.flush();
fOut.close();
Toast.makeText(getApplicationContext(), "Saved", Toast.LENGTH_SHORT).show();
OR
String strMyImagePath = f.getAbsolutePath();
FileOutputStream fos = null;
try {
fos = new FileOutputStream(f);
bitmap.compress(Bitmap.CompressFormat.PNG,70, fos);
fos.flush();
fos.close();
// MediaStore.Images.Media.insertImage(getContentResolver(), b, "Screen", "screen");
}catch (FileNotFoundException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
save22.setOnClickListener(new OnClickListener() {
