有時候需要判斷手機(jī)系統(tǒng)的ROM，檢測ROM是MIUI、EMUI還是Flyme，可以使用getprop命令，去系統(tǒng)build.prop文件查找是否有對應(yīng)屬性來判斷是什么ROM。build.prop的介紹可以看Android build.prop簡介

1. 小米

小米官方文檔：如何識別小米設(shè)備/MIUI系統(tǒng)
判斷小米設(shè)備
Build.MANUFACTURER是否為Xiaomi
查詢build.prop是否有ro.miui.ui.version.name屬性
ps:Build.MODEL是機(jī)器型號，小米2是MI 2
判斷MIUI版本
ro.miui.ui.version.name返回V5表示是MIUI V5系統(tǒng)，V6表示MIUI V6系統(tǒng)

2. 華為

查詢build.prop是否有ro.build.version.emui屬性

3. OPPO

查詢build.prop是否有ro.build.version.opporom屬性

4. VIVO

查詢build.prop是否有ro.vivo.os.version屬性

5. 錘子

查詢build.prop是否有ro.smartisan.version屬性

6. 魅族

Build.DISPLAY是否包含“FLYME”字符串

7. 360

Build.MANUFACTURER為“QIKU”或“360”

8. 樂視

待測試。。。

如果官方?jīng)]有給出用哪個屬性判斷，就要自己來決定了，一般系統(tǒng)ROM登記都有一個內(nèi)部版本號，是個不錯的選擇，例如小米ro.miui.ui.version.code，華為ro.build.hw_emui_api_level
