來(lái)點(diǎn)前奏說(shuō)明
當(dāng)你打開(kāi)這個(gè)文檔的時(shí)候残腌，你已經(jīng)做好準(zhǔn)備了叠艳，話(huà)不多說(shuō)開(kāi)搞烁登。前提你得有源碼职烧，源碼參考
Android源碼開(kāi)發(fā)篇（一）9.0/10.0源碼下載 編譯 刷機(jī)
在Android升級(jí)到P之后，Google默認(rèn)強(qiáng)制打開(kāi)了pre-odex防泵，導(dǎo)致本地調(diào)試的時(shí)候修改fw代碼push之后不work或者開(kāi)不了機(jī)器蚀之。原因在于打開(kāi)pre-odex的情況下，對(duì)于bootclasspath系統(tǒng)會(huì)默認(rèn)生成oat/art/vdex等文件捷泞，這些jar包之間相互依賴(lài)足删，耦合非常高。一旦修改push輕則不work锁右，重則系統(tǒng)出現(xiàn)未知的異常失受。
這對(duì)于本地編譯rom的調(diào)試帶來(lái)極大不便，這里提供一些方案盡量減少本地編譯的時(shí)間咏瑟，方便push調(diào)試拂到。
1、關(guān)閉pre-odex開(kāi)關(guān)
A 修改以下文件

source build/envsetup.sh
lunch aosp_sailfish-userdebug
B 配置如下宏關(guān)閉pre-odex
export WITH_DEXPREOPT=false
編譯framework.jar和services.jar
make framework -j8 && make services -j8
在aosp/out/target/product/sailfish/system/framework目錄下
adb root
adb remount
adb disable-verity
adb reboot
adb root
adb remount
adb push framework.jar system/framework/
如何驗(yàn)證framework.jar 是否成功和有效
我的做法修改LayoutInflater.java文件的
DEBUG修改為true
過(guò)濾LayoutInflater 這個(gè)關(guān)鍵字 隨機(jī)打開(kāi)應(yīng)用一般都會(huì)打印log的 如果輸出了就成功了 之后繼續(xù)搞起來(lái)吧码泞。兄旬。。

源碼導(dǎo)入Studio
source build/envsetup.sh
lunch aosp_sailfish-userdebug
mmm development/tools/idegen/
development/tools/idegen/idegen.sh
會(huì)在根目錄下面生成android.ipr和android.iml
過(guò)濾一些模塊
如果把Android所有的源碼全部導(dǎo)入到Android Studio里面去宋舷，工程將會(huì)非常大绪撵，而且會(huì)很耗時(shí)間，那么我們就可以把不需要的模塊給過(guò)濾掉祝蝠。
打開(kāi)android.iml文件音诈，加入以下代碼，修改excludeFolder的配置：
<excludeFolder url="file://$MODULE_DIR$/.repo"/>
<excludeFolder url="file://$MODULE_DIR$/abi"/>
<excludeFolder url="file://$MODULE_DIR$/frameworks/base/docs"/>
<excludeFolder url="file://$MODULE_DIR$/art"/>
<excludeFolder url="file://$MODULE_DIR$/bionic"/>
<excludeFolder url="file://$MODULE_DIR$/bootable"/>
<excludeFolder url="file://$MODULE_DIR$/build"/>
<excludeFolder url="file://$MODULE_DIR$/cts"/>
<excludeFolder url="file://$MODULE_DIR$/dalvik"/>
<excludeFolder url="file://$MODULE_DIR$/developers"/>
<excludeFolder url="file://$MODULE_DIR$/development"/>

<excludeFolder url="file://$MODULE_DIR$/system"/>
<excludeFolder url="file://$MODULE_DIR$/tools"/>
<excludeFolder url="file://$MODULE_DIR$/trusty"/>
<excludeFolder url="file://$MODULE_DIR$/vendor"/>
然后File -> Open---android.ipr 等待一大會(huì) 性能低的可能會(huì)卡住
