android 6之前版本判断应用是否有某个权限

1) 判断应用是否具有某个权限

PackageManager pm = getPackageManager();  
        boolean permission = (PackageManager.PERMISSION_GRANTED ==   
                pm.checkPermission("android.permission.RECORD_AUDIO", "packageName"));  
        if (permission) {  
            showToast("有这个权限");  
        }else {  
            showToast("木有这个权限");  
        }  

2)获取某个应用的权限清单

try {  
            PackageInfo pack = pm.getPackageInfo("packageName",PackageManager.GET_PERMISSIONS); 
            String[] permissionStrings = pack.requestedPermissions;  
            showToast("权限清单--->" + permissionStrings.toString());  
        } catch (NameNotFoundException e) {  
            e.printStackTrace();  
        }  

permissionStrings 是一个这样的字符串数组 

[android.permission.INTERNET,   
         android.permission.READ_PHONE_STATE,   
         android.permission.READ_CONTACTS,   
         ……  
         android.permission.READ_EXTERNAL_STORAGE,   
         android.permission.READ_CALL_LOG,   
         android.permission.WRITE_CALL_LOG]
