要求權限if (checkSelfPermission(Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation? if (shouldShowRequestPermissionRationale(Manifest.permission.READ_CONTACTS)) {
// Show an expanation to the user *asynchronously* -- don't block // this thread waiting for the user's response! After the user // sees the explanation, try again to request the permission.
} else {
// No explanation needed, we can request the permission.

// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an // app-defined int constant. The callback method gets the // result of the request. }}
處理回應@Overridepublic void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { switch (requestCode) { case MY_PERMISSIONS_REQUEST_READ_CONTACTS: { // If request is cancelled, the result arrays are empty. if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// permission was granted, yay! Do the // contacts-related task you need to do.
} else {
// permission denied, boo! Disable the // functionality that depends on this permission. } return; } }}
處理“不要再詢問我”
shouldShowRequestPermissionRationale(permission) == false
相容性
● 需要檢查 Build.VERSION_CODE < 23● 或是使用 Support v4
Asking for permission
一般時機
● 需要時再要求(map, 定位...)● 永遠不要有預設立場，在onCreate檢查
● 發送 Intent 時也需要權限
Service?1. 一開APP 馬上要求權限
2. 需要時發出Notification3. 隨時提醒使用者
Extras
建議
● 盡量隔離外部資源
● Permission API再包裝一層
Screen overlay● 無法更改權限屬正常行為
偷偷被藏起來的權限...● Manifest.permission.WRITE_SETTINGS● Manifest.permission.CHANGE_NETWORK_STATE● Manifest.permission.SYSTEM_ALERT_WINDOW
pre23| preinstalled permissions● Android M 之後預設無法使用
● Manifest.permission.WRITE_SETTINGS 可以經由 intent ACTION_MANAGE_WRITE_SETTINGS 開啟
