frameworks/base/core/res/res/values-zh-rCN/strings.xml
frameworks/base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java
在strings.xml文件中有该字段android_checking_file_system_title 

<string name="android_checking_file_system_title">"Android 正在检查文件系统..."</string>

在PhoneWindowManager.java文件中showBootMessage()方法中isNormal字段表示是否是正常开机启动，如果是异常开机启动就会弹出该对话框 " Android 正在检查文件系统…" 

publicvoidshowBootMessage(final CharSequence msg, final boolean always){if(mHeadless)return;

            @Override publicvoidrun(){if(mBootMsgDialog ==null){
