Which permissions should I ask at runtime and which I don't have to ask runtime in Android?

Question

How does I determine which permissions should I ask at runtime and which one is 'enough' to have declared in the manifest?

Answer 1

From the documentation:

System permissions are divided into two categories, normal and dangerous:

• Normal permissions do not directly risk the user's privacy. If your app lists a normal permission in its manifest, the system grants the permission automatically.

• Dangerous permissions can give the app access to the user's confidential data. If your app lists a normal permission in its manifest, the system grants the permission automatically. If you list a dangerous permission, the user has to explicitly give approval to your app.

See the documentation on normal permissions and dangerous permissions for more details.
