I need to modify the file that I show you below:
I have tried several ways but I always get an error. I leave the following code to know what I'm failing. Thank you very much.
try{
FileOutputStream archivo= new FileOutputStream("assets/prueba.json",true);
archivo.write("hola".getBytes());
} catch (IOException e) {
e.printStackTrace();
}
The Assets directory is read only, so you will not be able to write to it, but you can always use an internal file by doing something similar to:
String FILENAME = "prueba.json";
String string = "Esta es mi prueba";
FileOutputStream fos = openFileOutput(FILENAME, Context.MODE_PRIVATE);
fos.write(string.getBytes());
fos.close();
You can find more information on the subject in the Android developers guide: link
