Question

I wrote an Android application. These are the permissions I requested:

• INTERNET
• ACCESS-COARSE-LOCATION
• ACCESS-FINE-LOCATION
• ACCESS-NETWORK-STATE
• CHANGE-NETWORK-STATE

On 1.5 devices, it looks fine. I tried on a 2.0 device, and it also shows an additional permission when installing the app:

• SD CARD READ / WRITE

Is that just coming up by default now on any 2.0 device we install apps on? I do use Context.openFileOutput() to write a file to disk, but only to the app sandbox location, never to SD card.

Thanks

From the API docs, applications targeting DONUT or higher:

…must explicitly request the
WRITE_EXTERNAL_STORAGE permission to
be able to modify the contents of the
SD card. (Apps targeting earlier
versions will always request the
permission.)

Hence, if you are building a 1.5 app, you automatically get WRITE_EXTERNAL_STORAGE.
