display size 改为small

display size默认是default
改为small
frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java
private void loadSecureSettings(SQLiteDatabase db) {
…

•                   loadStringSetting(stmt, Settings.Secure.DISPLAY_DENSITY_FORCED,
  

•                R.string.def_display_size);
  

先把display size手动设为small,
通过获取手机物理密度的命令：adb shell wm density
获取def_display_size需要设置的值
