WRITE_EXTERNAL_STORAGE in Manifest

Question

I know that WRITE_EXTERNAL_STORAGE in the Manifest file allows my android application to write to external storage. Does WRITE_EXTERNAL_STORAGE mean also that my application will be installed automatically into the external storage of the devices from google play?

Thanks.

Answer 2

Does WRITE_EXTERNAL_STORAGE mean also that my application will be installed automatically into the external storage of the devices from google play?

No, however you may specify in the <manifest> tag the preferred install location:

<manifest 
          .....
          android:installLocation="preferExternal" >

Answer 3

No, this will only mean your app will ask for permission to write to external storage.

If you want your app to be installed on external storage your going to have to add the following to your apps manifest.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
android:installLocation="preferExternal"
... >
