答案 0 :(得分：1)
您需要设置运行时权限。
$ cd bar
$ realpath --no-symlinks file
/home/pet3r/test/foo/file
与写呼叫日志相同
您的MainActivity应该会这样
String wantPermission = Manifest.permission.READ_CALL_LOG;
// called in a standard activity, use ContextCompat.checkSelfPermission for AppCompActivity
int permissionCheck = checkSelfPermission(this, wantPermission);
if (!permissionCheck == PackageManager.PERMISSION_GRANTED) {
// user may have declined earlier, ask Android if we should show him a reason
if (shouldShowRequestPermissionRationale(MainActivity.this, wantPermission)) {
// show an explanation to the user
} else {
// request the permission.
// CALLBACK_NUMBER is a integer constants
requestPermissions(MainActivity.this, new String[]{wantPermission}, CALLBACK_NUMBER);
}
} else {
// got permission, use it
}
