运行时权限介绍

Android 6.0在原有的AndroidManifest.xml声明权限的基础上增加了动态申请运行时权限。新增的运行时权限有 身体传感器、日历、摄像头、通讯录、地理位置、麦克风、电话、短信、SD卡存储。

运行时权限处理方式

Android targetSdkVersion在23以下（不包括23），不需要动态申请运行时权限，所以可以通过降低targetSdkVersion的方式可以解决运行时权限申请的问题。这种方式不推荐。还有一种方式就是通过动态申请的方式解决。Android 6.0新增了一套关于权限申请的新的API。checkSelfPermission(...)，requestPermissions(...)来进行动态申请权限。在onRequestPermissionsResult()进行回调处理权限申请的结果。

代码示例如下：

package com.syz.example.permission;import android.Manifest;import android.app.Activity;import android.content.pm.PackageManager;import android.os.Build;import android.os.Bundle;import android.support.v4.content.ContextCompat;/** * Created by SYZ on 2016/12/30. */public class BaseActivity extends Activity {    /**     * 运行时权限 request code     */    private static final int RUNTIME_PERMISSION_REQUEST_CODE = 0X0000;    /**     * SD卡读写权限 request code     */    private static final int WRITE_EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE = 0X0001;    /**     * 摄像头权限 request code     */    private static final int CAMERA_PERMISSION_REQUEST_CODE = 0x0002;    /**     * 麦克风权限 request code     */    private static final int AUDIO_PERMISSION_REQUEST_CODE = 0X0003;    /**     * 日历权限 request code     */    private static final int CALENDAR_PERMISSION_REQUEST_CODE = 0x0004;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        requestPermission();    }    /**     * 请求运行时权限     * 注意：同一时刻只能发一次权限请求     */    private void requestPermission() {        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {            /**申请WRITE_EXTERNAL_STORAGE权限*/            int hasExternalStoragePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);            /** audio 权限*/            int hasAudioPermission = ContextCompat.checkSelfPermission(this, android.Manifest.permission.RECORD_AUDIO);            /** camera 权限*/            int hasVideoPermission = ContextCompat.checkSelfPermission(this, android.Manifest.permission.CAMERA);//            if (hasExternalStoragePermission != PackageManager.PERMISSION_GRANTED) {//                //申请WRITE_EXTERNAL_STORAGE权限//                ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},//                        WRITE_EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE);//            }//////            if (hasAudioPermission != PackageManager.PERMISSION_GRANTED ){//                requestPermissions(new String[]{android.Manifest.permission.RECORD_AUDIO},//                        AUDIO_PERMISSION_REQUEST_CODE);//            }////            if (hasVideoPermission != PackageManager.PERMISSION_GRANTED) {//                requestPermissions(new String[]{android.Manifest.permission.CAMERA},//                        CAMERA_PERMISSION_REQUEST_CODE);//            }            /** 音频麦克风，视频权限*/            if (hasAudioPermission != PackageManager.PERMISSION_GRANTED || hasVideoPermission != PackageManager.PERMISSION_GRANTED) {                requestPermissions(new String[] { android.Manifest.permission.RECORD_AUDIO, android.Manifest.permission.CAMERA },                        RUNTIME_PERMISSION_REQUEST_CODE);            }        }    }    @Override    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {        super.onRequestPermissionsResult(requestCode, permissions, grantResults);        doWithPermissionResult(requestCode,permissions,grantResults);    }    /**     * 运行时权限申请结果处理     * @param requestCode     * @param permissions     * @param grantResults     */    protected void doWithPermissionResult(int requestCode, String[] permissions, int[] grantResults){//        if (requestCode == WRITE_EXTERNAL_STORAGE_PERMISSION_REQUEST_CODE){//申请WRITE_EXTERNAL_STORAGE权限是否通过//            if (grantResults[0] == PackageManager.PERMISSION_GRANTED){//                // Permission Granted//            }else {//                // Permission Denied//            }//        }//        if (requestCode == AUDIO_PERMISSION_REQUEST_CODE){//音频权限//            if (grantResults[0] == PackageManager.PERMISSION_GRANTED){//                // Permission Granted//            }else {//                // Permission Denied//            }//        }//        if (requestCode == CAMERA_PERMISSION_REQUEST_CODE) {//摄像头权限//            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {//                // Permission Granted//            } else {//                // Permission Denied//            }//        }        if (requestCode == RUNTIME_PERMISSION_REQUEST_CODE) {//音频，摄像头权限            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {                // Permission Granted            } else {                // Permission Denied            }            if (grantResults[1] == PackageManager.PERMISSION_GRANTED){                // Permission Granted            } else {                // Permission Denied            }        }    }}
