android退出应用时候清除数据

退出应用的时候调用下面方法，就可以清楚数据了。

+        ActivityManager am = (ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);

+        boolean res = am.clearApplicationUserData();

+        if (!res) {

+            // Clearing data failed for some obscure reason. Just log error for now

+            Log.i("brower", "Couldnt clear application user data");

+  }
