Android Studio 2.1.2, API 23 Error: java.lang.SecurityException: No permission to write to/storage/emulated/0/Download/aabd.pdf: Neither user 10059 nor current process ha

Solution 1:

You have to check permission like this if you have targetSdk 23

if (Build.VERSION.SDK_INT == Build.VERSION_CODES.M) {
        checkPermission();
    }
    else {

    Filefile=newFile(Environment.getExternalStoragePublicDirectory
        (Environment.DIRECTORY_DOWNLOADS), nameOfFile);
            request.setDestinationInExternalPublicDir
        (Environment.DIRECTORY_DOWNLOADS, nameOfFile);
        request.setVisibleInDownloadsUi(true);
        myDownloadReference = downloadManager.enqueue(request);
    }


privatevoidcheckPermission() {
            if (ContextCompat.checkSelfPermission(this,
                    Manifest.permission.WRITE_EXTERNAL_STORAGE)
                    != PackageManager.PERMISSION_GRANTED && ContextCompat.checkSelfPermission(this,
                Manifest.permission.READ_EXTERNAL_STORAGE)
                != PackageManager.PERMISSION_GRANTED) {//Can add more as per requirement

                ActivityCompat.requestPermissions(this,
                        newString[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE},
                        123);

            } else {

            }
}

@OverridepublicvoidonRequestPermissionsResult(int requestCode,
                                       String permissions[], int[] grantResults) {
    switch (requestCode) {
        case123: {
            // If request is cancelled, the result arrays are empty.if (grantResults.length > 0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
         Filefile=newFile(Environment.getExternalStoragePublicDirectory
        (Environment.DIRECTORY_DOWNLOADS), nameOfFile);
            request.setDestinationInExternalPublicDir
        (Environment.DIRECTORY_DOWNLOADS, nameOfFile);
        request.setVisibleInDownloadsUi(true);
        myDownloadReference = downloadManager.enqueue(request);

            } else {

                checkPermission();
            }
            return;
        }
    }
}

Solution 2:

Is sd card emulation is enabled in emulator? you may want to use Genymotion emulator instead of built-in
