Android how to store my jpeg file in Mobile internal Storage. It doesn't have an SD CARD

Question

I want to save a picture file from Internet to my mobile. I have used both Internet and externalstorage Permission in AndroidManifest file. But it gives an error given below. I think it is because my device don't have an SD CARD. If so then I want to know how to store in Internal storage.

myError

java.io.FileNotFoundException: /storage/emulated/0/Pictures/GettyImages-460712009-560x450.jpg: open failed: EACCES (Permission denied Caused by: android.system.ErrnoException: open failed: EACCES (Permission denied)

Below is my code.

try {
        URL urlobj = new URL(url);
        connection= (HttpURLConnection) urlobj.openConnection();
        inputStream=connection.getInputStream();

           file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES).getAbsolutePath() + "/"+ Uri.parse(url).getLastPathSegment());

            FileOutputStream fileOutputStream = new FileOutputStream(file);

            int reed = -1;
            byte[] buffer = new byte[1024];

            // if no data is return -1 keep reading until -1
            while( ( reed=inputStream.read(buffer) )!= -1){

            fileOutputStream.write(buffer,0,reed);               
}

You are getting Permission denied Exception because you are not implementing Run Time permission for Devices having Android Marshmallow and above version ..

This is how you can achieve this :

Add following permission to manifest like earlier :

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

Match if the user has already granted the permission. If yes, skip asking for permission and continue with your work else ask user for permission :

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if (!Settings.System.canWrite(this)) {
            requestPermissions(new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,
                    Manifest.permission.READ_EXTERNAL_STORAGE}, 2909);
        } else {
            // your code
        }
    } else {
        // your code
    }

Permission result callback:

@Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case 2909: {
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    Log.e("Permission", "Granted");
                } else {
                    Log.e("Permission", "Denied");
                }
                return;
            }
        }
    }

To save an image in internal memory use this code.

You should add permission in you manifast file <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

You need run time permission in marshmallow and above version, for that use Amit sharma Answer.

Here is the code to save a file in Default picture directory.

private File createImageFile() throws IOException {
    // Create an image file name
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
    String imageFileName = "JPEG_" + timeStamp + "_";
    File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
    File image = File.createTempFile(
        imageFileName,  /* prefix */
        ".jpg",         /* suffix */
        storageDir      /* directory */
    );

    // Save a file: path for use with ACTION_VIEW intents
    mCurrentPhotoPath = image.getAbsolutePath();
    return image;
}
