android6.0 如何修改BUILD_ID

過程及步驟記錄：

1、在device-commom.mk裏重寫：

BUILD_NUMBER := 0.0.1
BUILD_ID := flying123123123

重新編譯後發現system/build.prop 裏面ro.build.id沒有改變還是默認值

2、嘗試直接修改build\core\build_id.mk

export BUILD_ID=MRA58K

修改爲export BUILD_ID=flying123123123

編譯錯誤：error: ro.build.fingerprint cannot exceed 91 bytes

網上找到對應方法：

3、編譯成功後升級發現開機後彈出窗口：

您的設備內部出現了問題，請聯繫您的設備製造商瞭解詳情

從打印信息中發現：

4、

frameworks\base\core\java\android\os\SystemProperties.java

public static final int PROP_VALUE_MAX = 91;//149;//91;            

system\core\debuggerd\test\sys\system_properties.h

#define PROP_VALUE_MAX  92//150//92
