Android 6.0權限授予

在android 6.0以及sdk23以上，權限就被分爲normal和dangerous

Dangerous Permision：

Permission Group	Permissions
CALENDAR	READ_CALENDAR WRITE_CALENDAR
CAMERA	CAMERA
CONTACTS	READ_CONTACTS WRITE_CONTACTS GET_ACCOUNTS
LOCATION	ACCESS_FINE_LOCATION ACCESS_COARSE_LOCATION
MICROPHONE	RECORD_AUDIO
PHONE	READ_PHONE_STATE CALL_PHONE READ_CALL_LOG WRITE_CALL_LOG ADD_VOICEMAIL USE_SIP PROCESS_OUTGOING_CALLS
SENSORS	BODY_SENSORS
SMS	SEND_SMS RECEIVE_SMS READ_SMS RECEIVE_WAP_PUSH RECEIVE_MMS
STORAGE	READ_EXTERNAL_STORAGE WRITE_EXTERNAL_STORAGE

危險權限設置：

int hasPermision = checkSelfPermission(Manifest.permission.CAMERA);
            if (hasPermision != PackageManager.PERMISSION_GRANTED) {
                if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA)) {
                    
                    AlertDialog dialog = new AlertDialog.Builder(this)
                            .setMessage("該相冊須要賦予訪問存儲的權限，不開啓將沒法正常工做, 是否受權?")
                            .setPositiveButton("肯定", new DialogInterface.OnClickListener() {
                                @Override
                                public void onClick(DialogInterface dialog, int which) {
                                    dialog.dismiss();
                                    ActivityCompat.requestPermissions(MainActivity.this,
                                            new String[]{Manifest.permission.CAMERA},
                                            PERMISION_ID);
                                }
                            })
                            .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                                @Override
                                public void onClick(DialogInterface dialog, int which) {
                                    dialog.dismiss();
                                    System.exit(0);
                                }
                            }).create();
                    dialog.show();
                } else {
                    
                    ActivityCompat.requestPermissions(this,
                            new String[]{Manifest.permission.CAMERA},
                            PERMISION_ID);
                }

checkSelfPermission(Manifest.permission.CAMERA)：判斷權限是否被授予

ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA)：判斷權限授予是否被拒絕，若是第一次權限授予的時候用戶拒絕授予權限，再次運行這段代碼時返回ture

 

處理權限申請回調：

@Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        if (requestCode == PERMISION_ID) {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                //權限授予成功
            } else {
                //權限授予失敗
            }
        }
    }

ps：若是權限在AndroidManifest中沒有申請過，是不會有權限授予彈出框出來的
