The answer given by user370305 is generally the correct one. Your third-party code should adequately document what permissions it needs -- combine that with the permissions your own code needs, and you should be set.

If you feel that this is insufficient, then:

Step #1: Write a unit test suite.

Step #2: Add tests to the suite until you have complete statement coverage.

Step #3: Get all tests passing in the unit test suite.

Step #4: Remove a permission and see if tests fail. Restore the permissions that cause test suite failure. Repeat for all permissions you are uncertain of.

For Android Studio:

1) Find which permissions are added (app\build\intermediates\manifests)

2) Add these permissions with tools:node="remove"

Example:

I found that I have unwanted permission:

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

And I removed it by adding this to my app manifest:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:node="remove"/>

You can remove the permission and check the lint results. If the results are clean then the permission is not being used.

Analyse -> Run Inspection by Name -> Type "Missing Permissions" -> Run
