Android：取得应用拥有的权限

Log输出某APP拥有的权限

PackageManager pm = context.getPackageManager();PackageInfo pi;try {    // 参数2必须是PackageManager.GET_PERMISSIONS    pi = pm.getPackageInfo(packageName, PackageManager.GET_PERMISSIONS);    String[] permissions = pi.requestedPermissions;    if(permissions != null){        for(String str : permissions){            Log.i(TAG, str);        }    }} catch (NameNotFoundException e) {    e.printStackTrace();}

上述代码中，packageName是目标APP的包名。

以List集合返回某APP拥有的权限信息

基于上述代码，修改为如下方式：

List<PermissionInfo> permissionInfoList = new ArrayList<PermissionInfo>();PackageManager pm = context.getPackageManager();PackageInfo pi;try {    pi = pm.getPackageInfo(packageName, PackageManager.GET_PERMISSIONS);    String[] permissions = pi.requestedPermissions;    if(permissions != null){        for(String str : permissions){            PermissionInfo permissionInfo = context.getPackageManager().getPermissionInfo(str, 0);            permissionInfoList.add(permissionInfo);        }    }} catch (NameNotFoundException e) {    e.printStackTrace();}return permissionInfoList;

基于上述代码，便可获得更为丰富的权限信息。
