How to find all parts in the code where permissions are needed

Question

I have a large project with lots of features that require permissions. The problem is that the developer who started this project a year ago, just added ALL possible permissions to the manifest. Now the problem is that i need to remove all permissions that are never used. Is there a nice way or tool to do that?

The way i thought about was to remove all permissions, then test, and add one by one after seeing a crash with SECURITY EXCEPTION. Also the stack trace contains a hint for which permission is missing. I do not think it is a nice or safe way to do it...

I tried the method explained here: How to check if Android Permission is actually being used? but it did only partial work. I removed all permissions and run inspection, but not all permissions were found. I use bluetooth in my code, and there were no notice of this permission missing...

Thank You, tried this on newer version of Android Studio and it worked. But not all permissions were found. I use bluetooth in my code, and there were no notice of this permission missing... — Pavel B., Sep 06 '16 at 11:44

in my guess first of All just look at the Dangerous permission list recognize your permissions from manifest file and all these permissions in a list just here in this library they did it in a same way it will handle all permission one by one just look at the example

askCompactPermissions(new String[]{PermissionUtils.Manifest_CAMERA, PermissionUtils.Manifest_WRITE_EXTERNAL_STORAGE}, new PermissionResult() {
        @Override
        public void permissionGranted() {
            //permission granted
            //replace with your action
        }

        @Override
        public void permissionDenied() {
            //permission denied
            //replace with your action
        }
         @Override
                public void permissionForeverDenied() {
                 // user has check 'never ask again'
                 // you need to open setting manually
                 //  Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                 //  Uri uri = Uri.fromParts("package", getPackageName(),  
                  null);
                 //   intent.setData(uri);
                 //  startActivityForResult(intent,   
                 REQUEST_PERMISSION_SETTING); 
                }
    });

for Activity extent yourActivityClass from ActivityManagePermission like below

public class MainActivity extends ActivityManagePermission {

}

and for Fragement extends yourFragmentClass from FragmentManagePermission

public class FragmentHome extends FragmentManagePermission {

}

Thank You, but the problem is that there is a very large amount of code and i need to find which permissions i should ask for... Or, on the opposite, which permissions i do not use, because as for now, my app has all possible permissions in its manifest, but i need to get rid of the unused ones... — Pavel B., Sep 06 '16 at 12:04
that all will be handle when you look at the Dangerous Permissions article the article i give you after that recognize permission from your manifest file and add all of your Dangerous permissions from your manifest file in a list to the method askCompactPermissions(new String[]{yourpermission1, yourpermission2,....}); — Nowshad, Sep 06 '16 at 12:10
The article You provided is very usefull, i read it before even asking the question, but it does not describe the solution to what i ask... — Pavel B., Sep 06 '16 at 12:59
