Android: add missing properties in AndroidManifest.xml

Some missing values has to be defined in AndroidManifest.xml, otherwise,
warnings might be thrown.

* android:exported="true": because the manifest sets an intent-filter,
and it then has to explicitly to avoid the warning [1].
* android:allowBackup="true": this has to be explicitly set, we set it
to the default value here [2].
* android:fullBackupOnly="false": SDK 23+ use this to deteremine to
user auto backup or not, we set it to the default value here [3].
