android Smali注入

来源：互联网发布：淘宝一元拍卖是真的吗编辑：程序博客网时间：2024/06/02 02:46

1，Log注入

const-string v1,"SN"
invoke-static {v1,v0}, Landroid/util/log;->v(Ljava/lang/String;Ljava/lang/String;)I

2，alertDialog

java代码
new AlertDialog.Builder(self)
.setTitle("普通对话框")
.setMessage("你好，Android!")
.show();

Smali代码
new-instance v1,Landroid/app/AlertDialog$Builder;
invoke-direct {v1,p0}, Landroid/app/AlertDialog$Builder;-><init>(Landroid/content/Context;)V
.line 29
.local v1,builder:Landroid/app/AlertDialog$Builder;
const-string v2,"\u666e\u901a\u5bf9\u8bdd\u6846"
invoke-virtual {v1,v2}, Landroid/app/AlertDialog$Builder;->setTitle(Ljava/lang/CharSequence;)Landroid/app/AlertDialog$Builder;
.line 31
const-string v2,"\u4f60\u597d\uff0cAndroid!"
invoke-virtual {v1,v2},Landroid/app/AlertDialog$Builder;->setMessage(Ljava/lang/CharSequence;)Landroid/app/AlertDialog$Builder;
.line 52
invoke-virtual {v1},Landroid/app/AlertDialog$Builder;->create()Landroid/app/AlertDialog;
move-result-object v2
invoke-virtual {v2},Landroid/app/AlertDialog;->show()V
将上述smali代码插入MainActivity.smali中的create函数的return-void语句前面

3，卡住程序运行

方法一：
try{
      Thread.sleep(60*1000);
}catch(InterruptedException e){
      e.printStackTrace();
}
.line 69
const-wide/32 v1,0xeff0
:try_start_0
#v1=(LongLo);v2=(LongHi);
invoke-static {v1,v2},Ljava/lang/Thread;->Sleep(J)V
:try_end_0
.catch Ljava/lang/InterruptedException; {:try_start_0 .. try_end_0} :catch_0
.line 87
:goto_0
#v0=(Conflicted);
#此后面是try后的内容
return-void
.line 70
:catch_0
#v0=(Uninit);
move-exception v0
.line 72
.local v0, e:Ljava/lang/InterruptedException;
#v0=(Reference);
invoke-virtual {v0}, Ljava/lang/InterruptedException;->printStackTrace()V
goto :goto_0
方法二:
android.os.SystemClock.sleep(60*1000);
smali
const-wide/32 v0, 0xea60
invoke-static {v0, v1}, Landroid/os/SystemClock;->sleep(J)V

4.栈跟踪(调用关系)

#new Exception("print trace").printStackTrace();
new-instance v0,Ljava/lang/Exception;
const-string v1,"print trace"
invoke-direct {v0,v1}, Ljava/lang/Exception;-><init>(Ljava/lang/String;)V
invoke-virtual {v0}, Ljava/lang/Exception;->printStackTrace()V
栈跟踪信息记录了程序从启动到printStackTrace()被执行期间所有被调用过的方法。从下往上查看栈跟踪信息，
找到第一条以com.android.stackTrace开头的信息。
栈跟踪信息是WARN级别，而且Tag名称被系统命令为System.err. 命令行：adb logcat -s System.err:V *:W

5.Method Profiling(调用关系)

#android.os.Debug.startMethodTracing("123"); "123"为文件名
#a();
#android.os.Debug.stopMethodTracing();
Android-Manifest.xml添加SD卡写入权限
<user-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
#android.os.Debug.startMethodTracing("123");
const-string v0, "123"
invoke-static {v0}, Landroid/os/Debug;->startMethodTracing(Ljava/lang/String;) V
#android.os.Debug.stopMethodTracing();
invoke-static {}, Landroid/os/Debug;->stopMethodTracing() V
SD卡的根目录生成123.trace
分析命令：
adb pull /mnt/sdcard/123.trace
traceview 123.trace
