How I can check if user accepted permission for read/write Contacts?

my app read contacts from cell phone so when it run he get for permission.

How I ask again or check if the user gave permission?

Thank you very much.

Answer 1

User's don't really have the option to chose which permissions they approve or not. It's either they approve everything and your app installs, or they chose to decline and then your app doesn't install.

However, to answer your question you can use the checkPermission method in the PackageManager

PackageManager manager = getPackageManager();
int hasPermission = manager.checkPermission ("android.permission.READ_CONTACTS", "com.your.package")
if (hasPermission == PackageManager.PERMISSION_GRANTED) {
    //you have permission
}
