OutOfMemoryError Растровое изображение в строку Base64

Question

У меня ошибка в Android, кто-то может мне помочь?

мой код активности:

    profileImage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            ActivityCompat.requestPermissions(
                    Connect.this,new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},CODE_GALLERY_REQUEST
            );
        }

    });



}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

    if(requestCode==CODE_GALLERY_REQUEST){
        if(grantResults.length>0 && grantResults[0]== PackageManager.PERMISSION_GRANTED){
            Intent intent = new Intent(Intent.ACTION_PICK);
            intent.setType("image/*");
            startActivityForResult(Intent.createChooser(intent,"Select Image"),CODE_GALLERY_REQUEST);
        }else {
            Toast.makeText(this," Pour créer une  photo de profil merci de nous donner la permission",Toast.LENGTH_SHORT);
        }
        return;
    }

    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}

@Override

    if(requestCode==CODE_GALLERY_REQUEST&&resultCode==RESULT_OK&&data!=null){

        Uri filePath=data.getData();
        try {
            InputStream inputStream = getContentResolver().openInputStream(filePath);
            bitmap = BitmapFactory.decodeStream(inputStream);
            imagedata = imageToString(bitmap);
            profileImage.setImageBitmap(bitmap);
        } catch (FileNotFoundException e) {
