Answer 1

Here how to retrieve the list of the apps installed on an Android device, and the permissions used by every app.

private static final String TAG = "MyActivity";  
...

final PackageManager pm = getPackageManager();
final List installedApps = pm.getInstalledApplications(PackageManager.GET_META_DATA);

for ( ApplicationInfo app : installedApps ) {
    //Details:
    Log.d(TAG, "Package: " + app.packageName);
    Log.d(TAG, "UID: " + app.uid);
    Log.d(TAG, "Directory: " + app.sourceDir);

    //Permissions:
    StringBuffer permissions = new StringBuffer();

    try {
        PackageInfo packageInfo = pm.getPackageInfo(app.packageName, PackageManager.GET_PERMISSIONS);

        String[] requestedPermissions = packageInfo.requestedPermissions;
        if ( requestedPermissions != null ) {
            for (int i = 0; i < requestedPermissions.length; i++) {
                permissions.append(requestedPermissions[i] + "\n");
            }

            Log.d(TAG, "Permissions: " + permissions);
        }
    }
    catch ( PackageManager.NameNotFoundException e ) {
        e.printStackTrace();
    }
}
