63 grants the permission automatically. If you list a dangerous permission, the
84 is 22 or lower: If you list a dangerous permission in your manifest, the user
85 has to grant the permission when they install the app; if they do not grant
86 the permission, the system does not install the app at all.

92 is running. The user can grant or deny each permission, and the app can

102 it's missing a needed permission, regardless of what API level your app
118 If your app needs a dangerous permission, you must check whether you have
119 that permission every time you perform an operation that requires that
120 permission. The user is always free to revoke the permission, so even if the
121 app used the camera yesterday, it can't assume it still has that permission
126 To check if you have a permission, call the {@link

142 the app has to explicitly ask the user for permission.
148 If your app needs a dangerous permission that was listed in the app manifest,
149 it must ask the user to grant the permission. Android provides several
150 methods you can use to request a permission. Calling these methods brings up a

168 app needs a permission. For example, if a user launches a photography app,
169 the user probably won't be surprised that the app asks for permission to use
171 user's location or contacts. Before you request a permission, you should
179 already turned down that permission request. If a user keeps trying to use
180 functionality that requires a permission, but keeps turning down the
181 permission request, that probably shows that the user doesn't understand why
182 the app needs the permission to provide that functionality. In a situation

195 <strong>Note:</strong> If the user turned down the permission request in the
196 past and chose the <strong>Don't ask again</strong> option in the permission

205 If your app doesn't already have the permission it needs, the app must call
209 an integer <em>request code</em> that you specify to identify this permission
219 The following code checks if the app has permission to read the user's
220 contacts, and requests the permission if necessary:
225 Manifest.permission.READ_CONTACTS)
230 Manifest.permission.READ_CONTACTS)) {
234 // sees the explanation, try again to request the permission.
238 // No explanation needed, we can request the permission.

341 If the user denies a permission request, your app should take appropriate
