MTK FMRadio 修改工做頻率範圍的方法

全球大部分國家的調頻廣播頻率範圍基本都是87.5-108.0 Mhz，但也有些例外，好比日本的爲76.0-90.0Mhz。

mtk平臺默認都是87.5-108.0Mhz，若是該機型銷往日本，那麼咱們就須要修改FM頻率範圍。

MTK已經預留好宏和變量，改個值就好，代碼是基於O的，可是這一塊基本沒什麼變化，O以前以及以後應該也是適用的，可能文件路徑會有改變

一、device/mediatek/common/kernel-headers/linux/fm.h 找到如下宏修改以下

#define FMR_BAND 3 //FM radio band, 1:87.5MHz~108.0MHz; 2:76.0MHz~90.0MHz; 3:76.0MHz~108.0MHz; 4:special
#define FMR_BAND_FREQ_L 760 //FM radio special band low freq(Default 87.5MHz)
#define FMR_BAND_FREQ_H 1080 //FM radio special band high freq(Default 108.0MHz)

#define FM_BAND_DEFAULT FM_BAND_JAPANW

#define FM_RAIDO_BAND FM_BAND_JAPANW
複製代碼

二、vendor/mediatek/proprietary/packages/apps/FMRadio/src/com/android/fmradio/FmUtils.java

修改以下幾個變量

// maximum station frequency
private static final int HIGHEST_STATION = 1080;
// minimum station frequency
private static final int LOWEST_STATION = 760;
// maximum station frequency 50khz
private static final int HIGHEST_STATION_50KHZ = 10800;
// minimum station frequency 50khz
private static final int LOWEST_STATION_50KHZ = 7600;

第三方應用白名單

不少出貨國內要使用freeme os的客戶，好比天龍世紀、南極星，基本都要內置某個對講類的app。因爲 freeme os的對第三方應用的限制不少，內置這些應用時須要注意解除一些限制，保證此類app功能正常運行。

針對freeme 8.1 （android O1）總結以下：

一、默認賦予該應用申請的全部權限

vendor/freeme/frameworks/base/data/etc/default-permissions-freeme.xml
具體寫法可參考該文件的內容，好比：  
<exception
package="com.ctchat.sample"
type=""
trust="true" >
</exception>
複製代碼

二、設置-應用-自啓動管理，默認打開開關後臺服務才能收到開機廣播或者其餘廣播

vendor/freeme/packages/providers/FreemeConfigProvider/RRO/res/values/arrays.xml，添加item便可默認打開
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string-array name="config_atlas_custom_white_list" translatable="false">
<item>com.ctchat.sample</item>
</string-array>
</resources>
複製代碼

三、點擊最近應用裏的清理會殺死不帶鎖的應用，須要默認上鎖

vendor/freeme/packages/providers/FreemeSettingsProvider/res/values/defaults.xml
<string name="def_sysui_recent_locked_tasks" translatable="false">com.ctchat.sample</string>
複製代碼

四、桌面一鍵清理、設置-安全中內心的懸浮窗管理和通知管理，這三項都須要找負責安全中心來客制，他會提供給你如下文件去override便可

vendor/freeme/packages/apps/security/Security/default_local_config

五、進程保活，低內存時不輕易被系統殺掉

vendor/freeme/frameworks/base/core/java/com/freeme/internal/util/FreemeCustomizedOom.java
private static final Map<String, Integer> DEFAULT_APP_ADJ_MAP = new HashMap<String, Integer>() {{
     put("com.ctchat.sample", HEAVY_WEIGHT_APP_ADJ);
}};
