Android获取某应用所申请的权限

来源：互联网发布：数控编程过程编辑：程序博客网时间：2024/06/05 16:45

应用在执行某些动作时需要向系统申请权限，比如启动摄像头，打电话等。如何知道某个应用申请了哪些权限？在安装时候可以看到，也可以在权限管理的应用中看到。还可以写一个应用来获取。我这里把写死了。其实可以做一个对话框，输入应用的包名，然后获取该应用所申请的权限。代码不多，直接贴出来。

package com.shengteng.checkpermissions;import android.app.Activity;import android.content.pm.PackageManager;import android.os.Bundle;import android.util.Log;import android.widget.TextView;public class MainActivity extends Activity {    //想要查看申请权限的包的包名    String mPackName = "com.fey.bclient";    boolean[] mPM=new boolean[13];    String[] mPermissionName={"连接互联网权限","连接网络权限","改变网络连接权限","改变wifi状态权限","连接wifi权限","读取电话号码权限","发送短信权限","读短信权限","写短信权限","删除短信权限","挂载-卸载文件系统权限","写SD卡权限","读SD卡权限"};    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        TextView textView = (TextView) findViewById(R.id.gettextview);        textView.setText("");        //获取包管理工具        PackageManager pm = getPackageManager();        mPM[0] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.INTERNET", mPackName));        mPM[1] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.ACCESS_NETWORK_STATE", mPackName));        mPM[2] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.CHANGE_NETWORK_STATE", mPackName));        mPM[3] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.CHANGE_WIFI_STATE", mPackName));        mPM[4] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.ACCESS_WIFI_STATE", mPackName));        mPM[5] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.READ_PHONE_STATE", mPackName));        mPM[6] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.SEND_SMS", mPackName));        mPM[7] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.READ_SMS", mPackName));        mPM[8] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.WRITE_SMS", mPackName));        mPM[9] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.RECEIVE_SMS", mPackName));        mPM[10] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.MOUNT_UNMOUNT_FILESYSTEMS", mPackName));        mPM[11] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.WRITE_EXTERNAL_STORAGE", mPackName));        mPM[12] = (PackageManager.PERMISSION_GRANTED == pm.checkPermission("android.permission.READ_EXTERNAL_STORAGE", mPackName));        for(int i=0;i< mPM.length;i++){            if(mPM[i]){                Log.i("TAG",""+mPM[i]);                textView.append(mPermissionName[i]+"  "+"true"+"\n");            }else{                //textView.setTextColor(Color.rgb(255, 0, 0));                textView.append(mPermissionName[i]+"  "+"false"+"\n");            }        }    }}
