最近在學(xué)習(xí)使用unidgb，調(diào)試模式學(xué)起來(lái)
unidgb 有3種調(diào)試模式：

public enum  DebuggerType {

    /**
     * console debugger
     */
    CONSOLE,

    /**
     * gdb server
     */
    GDB_SERVER,

    /**
     * ida android server v7.x
     */
    ANDROID_SERVER_V7

}

源碼寫(xiě)得很清楚了，分別是 CONSOLE、GDB_SERVER、ANDROID_SERVER_V7
暫時(shí)只懂CONSOLE模式，那就分享下吧

開(kāi)啟調(diào)試模式：

只需要增加下面得代碼，自己決定在哪個(gè)位置斷點(diǎn)

       Debugger MyDbg = emulator.attach(DebuggerType.CONSOLE);
       MyDbg.addBreakPoint(module.base + 0x2D180); //斷點(diǎn)地址

調(diào)試方法

運(yùn)行得時(shí)候，就會(huì)自動(dòng)斷點(diǎn)了，控制臺(tái)模式最重要得是知道命令：（unidbg會(huì)有提示的）

c: continue
n: step over
bt: back trace

st hex: search stack
shw hex: search writable heap
shr hex: search readable heap
shx hex: search executable heap

nb: break at next block
s|si: step into
s[decimal]: execute specified amount instruction
s(blx): execute util BLX mnemonic, low performance

m(op) [size]: show memory, default size is 0x70, size may hex or decimal
mr0-mr7, mfp, mip, msp [size]: show memory of specified register
m(address) [size]: show memory of specified address, address must start with 0x

wr0-wr7, wfp, wip, wsp <value>: write specified register
wb(address), ws(address), wi(address) <value>: write (byte, short, integer) memory of specified address, address must start with 0x
wx(address) <hex>: write bytes to memory at specified address, address must start with 0x

b(address): add temporarily breakpoint, address must start with 0x, can be module offset
b: add breakpoint of register PC
r: remove breakpoint of register PC
blr: add temporarily breakpoint of register LR

p (assembly): patch assembly at PC address
where: show java stack trace

trace [begin end]: Set trace instructions
traceRead [begin end]: Set trace memory read
traceWrite [begin end]: Set trace memory write
vm: view loaded modules
vbs: view breakpoints
d|dis: show disassemble
d(0x): show disassemble at specify address
stop: stop emulation
run [arg]: run test
cc size: convert asm from 0x4002d182 - 0x4002d182 + size bytes to c function

命令簡(jiǎn)單學(xué)習(xí)

暫時(shí)會(huì)的命令說(shuō)明類比(同idea類比)下（好記性不如爛筆頭）：
c - F8
n - F9
d - Varibles 窗口

輸入：

d

輸出：
