java.io.FileNotFoundException: /app.properties: open failed: EROFS (Read-only file system)

Question

I would like to create file of format .properties in android app. Unfortunately, I am getting error java.io.FileNotFoundException: /app.properties: open failed: EROFS (Read-only file system) Any idea why?

and also check that you gave WRITE_EXTERNAL_STORAGE permission in manifest.. — Ranjit, Mar 14 '14 at 11:40

try to use "android.permission.WRITE_INTERNAL_STORAGE" insert it to AndroidManifest.xml example's below:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.megazy.android"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="15"
        android:targetSdkVersion="17" />

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_INTERNAL_STORAGE" />

This answer is utterly false - **There is no such permision** – Chris Stratton Apr 23 '16 at 02:07
Yes there is no such permission, WRITE_INTERNAL_STORAGE. This should not be marked as correct-answer. – Hassan Siddique Apr 24 '16 at 13:23

Of course you cannot write to a file called

 /app.properties

as that would be located in the top-level or root directory of the device, to which application code will never have write access.

See the Saving Files section of the developer docs to learn about valid places to store a file, and which do and do not require additional attainable permissions.
