删除SharedPreferences的存储记忆

 1 SharedPreferences mSharedPreferences;
 2     SharedPreferences.Editor editor;
 3 mSharedPreferences = getSharedPreferences("user", MODE_PRIVATE);
 4 
 5         // 存入数据
 6         editor.putInt("INT_KEY", 0);
 7         editor.commit();这里，我们就将其移除：
 8 File file = new File("/data/data/"
 9                             + getPackageName().toString() + "/shared_prefs",
10                             "user.xml");
11                     if (file.exists()) {
12 
13                         boolean flag = file.delete();
14                         if (flag) {
15 
16                             Toast.makeText(UserInfoActivity.this, "删除成功",
17                                     Toast.LENGTH_LONG).show();
18                             UserInfoActivity.this.finish();
19                             Intent intent = new Intent();
20                             intent.setClass(UserInfoActivity.this,
21                                     HomeActivity.class);
22                             startActivity(intent);
23 }
24 else{
25 
26 }
