How to Save the Image to Sd Card on Button Click Android

How to save the image to SD card on button Click android

First, you need to get your Bitmap. You can already have it as an object Bitmap, or you can try to get it from the ImageView such as:

    BitmapDrawable drawable = (BitmapDrawable) mImageView1.getDrawable();
    Bitmap bitmap = drawable.getBitmap();

Then you must get to directory (a File object) from SD Card such as:

    File sdCardDirectory = Environment.getExternalStorageDirectory();

Next, create your specific file for image storage:

    File image = new File(sdCardDirectory, "test.png");

After that, you just have to write the Bitmap thanks to its method compress such as:

    boolean success = false;

    // Encode the file as a PNG image.
    FileOutputStream outStream;
    try {

        outStream = new FileOutputStream(image);
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream); 
        /* 100 to keep full quality of the image */

        outStream.flush();
        outStream.close();
        success = true;
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }

Finally, just deal with the boolean result if needed. Such as:

    if (success) {
        Toast.makeText(getApplicationContext(), "Image saved with success",
                Toast.LENGTH_LONG).show();
    } else {
        Toast.makeText(getApplicationContext(),
                "Error during image saving", Toast.LENGTH_LONG).show();
    }

Don't forget to add the following permission in your Manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

How can I save my current shown image when I click a imageview(button)?

Try this code:

imageview.setDrawingCacheEnabled(true); //Add this line.
imageview.buildDrawingCache();
Bitmap bm=imageview.getDrawingCache();

To save it in a file:

OutputStream fOut = null;
    Uri outputFileUri;
    try {
         File root = new File(Environment.getExternalStorageDirectory()
          + File.separator + "folder_name" + File.separator);
         root.mkdirs();
         File sdImageMainDirectory = new File(root, "myPicName.jpg");
         outputFileUri = Uri.fromFile(sdImageMainDirectory);
         fOut = new FileOutputStream(sdImageMainDirectory);
    } catch (Exception e) {
         Toast.makeText(this, "Error occured. Please try again later.",
         Toast.LENGTH_SHORT).show();
    }

    try {
        bm.compress(Bitmap.CompressFormat.PNG, 100, fOut);
        fOut.flush();
        fOut.close();
    } catch (Exception e) 
}

And don't forget to add permission in manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Hope it will help you :)

Android Studio: save image in SD Card

First, you need to get your Bitmap. You can already have it as an object Bitmap, or you can try to get it from the ImageView such as:

BitmapDrawable drawable = (BitmapDrawable) mImageView1.getDrawable();
Bitmap bitmap = drawable.getBitmap();

Then you must get to directory (a File object) from SD Card such as:

File sdCardDirectory = Environment.getExternalStorageDirectory();

Next, create your specific file for image storage:

File image = new File(sdCardDirectory, "test.png");

After that, you just have to write the Bitmap thanks to its method compress such as:

boolean success = false;

// Encode the file as a PNG image.
FileOutputStream outStream;
try {

    outStream = new FileOutputStream(image);
    bitmap.compress(Bitmap.CompressFormat.PNG, 100, outStream); 
    /* 100 to keep full quality of the image */

    outStream.flush();
    outStream.close();
    success = true;
} catch (FileNotFoundException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

Finally, just deal with the boolean result if needed. Such as:

if (success) {
    Toast.makeText(getApplicationContext(), "Image saved with success",
            Toast.LENGTH_LONG).show();
} else {
    Toast.makeText(getApplicationContext(),
            "Error during image saving", Toast.LENGTH_LONG).show();
}

Don't forget to add the following permission in your Manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Save ImageView to sdcard android

Use the below methods to save it to SdCard:

@Override
protected void onActivityResult(int reqCode, int resCode, Intent data) {
    if(resCode == RESULT_OK){
        if(reqCode == 1)
            imageView.setImageURI(data.getData());
            Bitmap bm=((BitmapDrawable)imageView.getDrawable()).getBitmap();
            saveImageFile(bm);
    }
}

    public String saveImageFile(Bitmap bitmap) {
            FileOutputStream out = null;
            String filename = getFilename();
            try {
                out = new FileOutputStream(filename);
                bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
            } catch (FileNotFoundException e) {
                e.printStackTrace();
            }
            return filename;
        }

        private String getFilename() {
            File file = new File(Environment.getExternalStorageDirectory()
                    .getPath(), "TestFolder");
            if (!file.exists()) {
                file.mkdirs();
            }
            String uriSting = (file.getAbsolutePath() + "/"
                    + System.currentTimeMillis() + ".jpg");
            return uriSting;
        }

How to save transformed image to SD card

Add a Callback to the Picasso proccess:

 .into(photo,new com.squareup.picasso.Callback() {
                    @Override
                    public void onSuccess() {
                        //Save image method
                    }

                    @Override
                    public void onError() {
                        //Error loading the image
                    }
                });

I hope that I have answered your question :)

Save image to sdcard from drawable resource on Android

The process of saving a file (which is image in your case) is described here: save-file-to-sd-card

---

Saving image to sdcard from drawble resource:

Say you have an image namely ic_launcher in your drawable. Then get a bitmap object from this image like:

Bitmap bm = BitmapFactory.decodeResource( getResources(), R.drawable.ic_launcher);

The path to SD Card can be retrieved using:

String extStorageDirectory = Environment.getExternalStorageDirectory().toString();

Then save to sdcard on button click using:

File file = new File(extStorageDirectory, "ic_launcher.PNG");
    FileOutputStream outStream = new FileOutputStream(file);
    bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
    outStream.flush();
    outStream.close();

Don't forget to add android.permission.WRITE_EXTERNAL_STORAGE permission.

Here is the modified file for saving from drawable: SaveToSd
, a complete sample project: SaveImage
