Question

I am doing an application with android 2.2, i created a file config.properties in the assets folder, i am trying modify the properties with the following code:

AssetManager am = this.getResources().getAssets();
Properties pp = new Properties();

InputStream isConfig = am.open("config.properties",Context.MODE_PRIVATE);           
pp.load(isConfig);

pp.setProperty("SHOP_URL", "NEW_SHOP_URL");//This key exists

try {
    pp.store(new FileOutputStream("config.properties"), null);
} catch (FileNotFoundException e) {
    e.printStackTrace();
}catch (IOException e) {
    e.printStackTrace();
}

When run the application,throw this error:
java.io.FileNoFoundException: Read-only file system.

I am trying adding permissions to solve this error,but i dont know which add.

Thanks by help

Answer 1

The problem here is the file path. try using

try {
    pp.store(getAssets().openFd("config.properties").createOutputStream(), null);
} catch (FileNotFoundException e) {
    e.printStackTrace();
}catch (IOException e) {
    e.printStackTrace();
}

this should fix the path problem.
