Android 6.0 7.0及以上 动态权限

android 6.0版本开始，google粑粑处于安全性考虑，敏感的权限只在manifest注册已经不可以了（例如摄像头权限，定位权限等等），需要在代码中动态注册。

以下对权限做一些介绍（转载）：

以下是需要单独申请的权限，共分为9组，每组只要有一个权限申请成功了，就默认整组权限都可以使用了。

 group:android.permission-group.CONTACTS    permission:android.permission.WRITE_CONTACTS    permission:android.permission.GET_ACCOUNTS        permission:android.permission.READ_CONTACTS  group:android.permission-group.PHONE    permission:android.permission.READ_CALL_LOG    permission:android.permission.READ_PHONE_STATE     permission:android.permission.CALL_PHONE    permission:android.permission.WRITE_CALL_LOG    permission:android.permission.USE_SIP    permission:android.permission.PROCESS_OUTGOING_CALLS    permission:com.android.voicemail.permission.ADD_VOICEMAIL  group:android.permission-group.CALENDAR    permission:android.permission.READ_CALENDAR    permission:android.permission.WRITE_CALENDAR  group:android.permission-group.CAMERA    permission:android.permission.CAMERA  group:android.permission-group.SENSORS    permission:android.permission.BODY_SENSORS  group:android.permission-group.LOCATION    permission:android.permission.ACCESS_FINE_LOCATION    permission:android.permission.ACCESS_COARSE_LOCATION  group:android.permission-group.STORAGE    permission:android.permission.READ_EXTERNAL_STORAGE    permission:android.permission.WRITE_EXTERNAL_STORAGE  group:android.permission-group.MICROPHONE    permission:android.permission.RECORD_AUDIO  group:android.permission-group.SMS    permission:android.permission.READ_SMS    permission:android.permission.RECEIVE_WAP_PUSH    permission:android.permission.RECEIVE_MMS    permission:android.permission.RECEIVE_SMS    permission:android.permission.SEND_SMS    permission:android.permission.READ_CELL_BROADCASTS

以下是普通权限，只需要在AndroidManifest.xml中申请即可：

 android.permission.ACCESS_LOCATION_EXTRA_COMMANDS  android.permission.ACCESS_NETWORK_STATE  android.permission.ACCESS_NOTIFICATION_POLICY  android.permission.ACCESS_WIFI_STATE  android.permission.ACCESS_WIMAX_STATE  android.permission.BLUETOOTH  android.permission.BLUETOOTH_ADMIN  android.permission.BROADCAST_STICKY  android.permission.CHANGE_NETWORK_STATE  android.permission.CHANGE_WIFI_MULTICAST_STATE  android.permission.CHANGE_WIFI_STATE  android.permission.CHANGE_WIMAX_STATE  android.permission.DISABLE_KEYGUARD  android.permission.EXPAND_STATUS_BAR  android.permission.FLASHLIGHT  android.permission.GET_ACCOUNTS  android.permission.GET_PACKAGE_SIZE  android.permission.INTERNET  android.permission.KILL_BACKGROUND_PROCESSES  android.permission.MODIFY_AUDIO_SETTINGS  android.permission.NFC  android.permission.READ_SYNC_SETTINGS  android.permission.READ_SYNC_STATS  android.permission.RECEIVE_BOOT_COMPLETED  android.permission.REORDER_TASKS  android.permission.REQUEST_INSTALL_PACKAGES  android.permission.SET_TIME_ZONE  android.permission.SET_WALLPAPER  android.permission.SET_WALLPAPER_HINTS  android.permission.SUBSCRIBED_FEEDS_READ  android.permission.TRANSMIT_IR  android.permission.USE_FINGERPRINT  android.permission.VIBRATE  android.permission.WAKE_LOCK  android.permission.WRITE_SYNC_SETTINGS  com.android.alarm.permission.SET_ALARM  com.android.launcher.permission.INSTALL_SHORTCUT  com.android.launcher.permission.UNINSTALL_SHORTCUT

此处对动态请求权限提供一个我用的方法，以动态请求相机权限和定位权限为例：

引入一个开源框架，用于权限管理，然后当前布局实现

EasyPermissions.PermissionCallbacks

/**权限管理**/compile 'pub.devrel:easypermissions:0.2.0'

/** * 请求权限 *///比如用到调用相机，调用的方法写在getPermiss（）方法里边private void getPermiss() {    //检查是否已经赋予了所有权限    if (EasyPermissions.hasPermissions(this, Manifest.permission.CAMERA)) {        //相机操作        } else {        //有权限没有被赋予去请求权限        EasyPermissions.requestPermissions(this, "需要请求camera权限", REQUEST_CAMERA_PERM, Manifest.permission.CAMERA);    }}

//定位权限private void getFineLocationPermiss() {    //检查是否已经赋予了所有权限(小米手机拒绝后检测时会误显示授予了权限)    if (EasyPermissions.hasPermissions(this, Manifest.permission.ACCESS_FINE_LOCATION)) {        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {            AppOpsManager appOpsManager = (AppOpsManager) getSystemService(Context.APP_OPS_SERVICE);            int checkOp = appOpsManager.checkOp(AppOpsManager.OPSTR_FINE_LOCATION, Binder.getCallingUid(), getPackageName());            if (checkOp == AppOpsManager.MODE_IGNORED) {                //权限被拒绝了（显示权限弹窗，避免用户多次拒绝后点击不再提示权限请求）               new AppSettingsDialog.Builder(this, "当前App需要申请定位权限,需要打开设置页面么?")                        .setTitle("权限申请")                        .setPositiveButton("确认")                        .setNegativeButton("取消", null  /*click listener*/)                        .setRequestCode(ACCESS_FINE_LOCATION)                        .build()                        .show();            } else {                //定位操作            }        } else {            //版本较低，直接进行定位操作

        }    } else {        //有权限没有被赋予去请求权限        EasyPermissions.requestPermissions(this, "需要请求定位权限", ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION);    }}//重写onRequestPermissionsResult将值传递给EasyPermissions.onRequestPermissionsResult();//固定写法@Overridepublic void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {    super.onRequestPermissionsResult(requestCode, permissions, grantResults);    EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);}/** * 权限请求成功 * * @param requestCode 权限请求码 * @param perms       权限请求集合 */@Overridepublic void onPermissionsGranted(int requestCode, List<String> perms) {}/** * 权限请求失败 * * @param requestCode 权限请求吗 * @param perms       权限集合 */@Overridepublic void onPermissionsDenied(int requestCode, List<String> perms) {    for (String per :            perms) {        Log.e("权限", per);    }

 //权限被拒绝了（显示权限弹窗，避免用户多次拒绝后点击不再提示权限请求）
    if (perms.get(0).equals("android.permission.ACCESS_FINE_LOCATION")) {   

     if (EasyPermissions.somePermissionPermanentlyDenied(this, perms)) {       

     new AppSettingsDialog.Builder(this, "当前App需要申请定位权限,需要打开设置页面么?")        

                      .setTitle("权限申请")                 

      .setPositiveButton("确认")              

            .setNegativeButton("取消", null /* click listener */)      

                      .setRequestCode(ACCESS_FINE_LOCATION)     

                 .build()               

                                           .show();   

     }  

  }   

 if (perms.get(0).equals("android.permission.CAMERA")) {   

     if (EasyPermissions.somePermissionPermanentlyDenied(this, perms)) {     

       new AppSettingsDialog.Builder(this, "当前App需要申请camera权限,需要打开设置页面么?")             

                                            .setTitle("权限申请")             

                 .setPositiveButton("确认")           

            .setNegativeButton("取消", null /* click listener */)        

                                            .setRequestCode(REQUEST_CAMERA_PERM)                

                                            .build()                

                                            .show();        

}   

 }

}/*END*/

此外，提供一个简单的权限请求方式（以读写内存为例）：

public class PermissionUtil {

private static String[] PERMISSIONS_STORAGE = {        Manifest.permission.READ_EXTERNAL_STORAGE,        Manifest.permission.WRITE_EXTERNAL_STORAGE};

private static final int REQUEST_EXTERNAL_STORAGE = 1;//权限请求码

public static void requestPermissions(Activity mActivity) {    int permission = ActivityCompat.checkSelfPermission(mActivity, Manifest.permission.WRITE_EXTERNAL_STORAGE);//检查是否有权限（此处读写权限获取其一就可以）    if (permission != PackageManager.PERMISSION_GRANTED) {        ActivityCompat.requestPermissions(                mActivity,                PERMISSIONS_STORAGE,                REQUEST_EXTERNAL_STORAGE        );          } else {        //已获取权限，进行相关操作    }
}
}
