Android_设备隐私获取，忽略6.0权限管理
小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

同一組的不論什么一個(gè)權(quán)限被授權(quán)了，其它權(quán)限也自己主動(dòng)被授權(quán)。比如，一旦WRITE_CONTACTS被授權(quán)了，app也有READ_CONTACTS和GET_ACCOUNTS了。
源代碼中被用來(lái)檢查和請(qǐng)求權(quán)限的方法各自是Activity的checkSelfPermission和requestPermissions。這些方法api23引入。

1.前言
(1).因?yàn)镸IUI等部分國(guó)產(chǎn)定制系統(tǒng)也有權(quán)限管理，沒(méi)有相關(guān)api。故無(wú)法推斷用戶是否同意獲取聯(lián)系人等隱私。在Android 6.0之后，新增權(quán)限管理能夠通過(guò)官方api推斷用戶的執(zhí)行狀態(tài)；
(2).我們指定targetSdkVersion為23或者之后我們還須要在執(zhí)行時(shí)請(qǐng)求這些所需的權(quán)限。這非常重要。由于已經(jīng)出現(xiàn)了非常多開(kāi)發(fā)人員把targetSdkVersion飆到了最新。然后發(fā)現(xiàn)自己的app瘋狂的崩潰，這是由于他們沒(méi)有實(shí)現(xiàn)執(zhí)行執(zhí)行時(shí)權(quán)限請(qǐng)求的代碼。當(dāng)你已經(jīng)把一個(gè)targeting API 為23或者之后的app公布到了Google Play上，這更是一個(gè)問(wèn)題。你無(wú)法馬上把那個(gè)apk的targeting API替換成更早的版本號(hào)。
2.權(quán)限分析
從Android6.0開(kāi)始。權(quán)限分為普通權(quán)限和許可權(quán)限。許可權(quán)限分類(lèi)歸組，一個(gè)權(quán)限授權(quán)之后，該組下的權(quán)限均可使用。
(1)普通權(quán)限
僅僅須要在xml申請(qǐng)就可以。用法和之前6.0曾經(jīng)的一樣。在應(yīng)用安裝應(yīng)用時(shí)，會(huì)默認(rèn)獲得許可。
(2)許可權(quán)限
可運(yùn)行 $adb shell pm list permissions -d -g
| android.permission-group.CALENDAR |
|
| android.permission-group.CAMERA |
|
| android.permission-group.CONTACTS |
|
| android.permission-group.LOCATION |
|
| android.permission-group.MICROPHONE |
|
| android.permission-group.PHONE |
|
| android.permission-group.SENSORS |
|
| android.permission-group.SMS |
|
| android.permission-group.STORAGE |
|
同一組的不論什么一個(gè)權(quán)限被授權(quán)了，其它權(quán)限也自己主動(dòng)被授權(quán)。比如，一旦WRITE_CONTACTS被授權(quán)了，app也有READ_CONTACTS和GET_ACCOUNTS了。
源代碼中被用來(lái)檢查和請(qǐng)求權(quán)限的方法各自是Activity的checkSelfPermission和requestPermissions。這些方法api23引入。
3.相關(guān)方法
(1).ContextCompat.checkSelfPermission()
檢查應(yīng)用是否擁有該權(quán)限。被授權(quán)返回值為PERMISSION_GRANTED。否則返回PERMISSION_DENIED
(2).ActivityCompat.requestPermissions()
將彈出請(qǐng)求授權(quán)對(duì)話框，這種方法在M之前版本號(hào)調(diào)用，OnRequestPermissionsResultCallback 直接被調(diào)用，帶著正確的 PERMISSION_GRANTED或者 PERMISSION_DENIED 。
(3).AppCompatActivity.onRequestPermissionsResult()
該方法類(lèi)似于Activity的OnActivityResult()的回調(diào)方法，主要接收請(qǐng)求授權(quán)的返回值

4.封裝
