The highest API level is which this permission should is granted to your app. Setting This attribute is useful if the permission your app requires are no longer needed beginningat a certain API level.

For example, beginning with Android 4.4 (API level), it's no longer necessary for your Appto request the WRITE_EXTERNAL_STORAGE Permissi On while YourApp wants to write to the IT own application-specific directories on external storage (the directoriesprovided by getExternalFilesDir()). However,the permission is required for API level and lower. So you can declare, that thispermission are needed only on the API level and a declaration such as this:

<uses-permission   android:name="Android.permission.WRITE_EXTERNAL_STORAGE"    Android:maxsdkversion="/> "

This is, beginning with API level, the system would no longer grant your app the WRITE_EXTERNAL_STORAGE permission.

API Level 1
