Accessing Internal and External Storage
- Starting with Android 4.4, reading or writing files in your app's private directories does not require the READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE permissions
- Therefor you can declare the permission should be requested only on the lower versions of Android by adding the maxSdkVersion attribute:
<manifest ...>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
android:maxSdkVersion="18" />
...
</manifest>
