逆向工具-java2smali

首先得安装查看smali代码的插件:java2smali

安装完成之后得重启AS,重启之后再build里面有操作选项进行转换操作.

转换完成之后就可以查看转换之后的smali代码了.

转换的java代码如下:

package msl.cc.com.mmmm;

import android.content.Context;
import android.database.ContentObserver;
import android.os.Handler;

public class SMSContentObserver extends ContentObserver {
    private static final int MSG_INBOX = 1;
    private Context mContext;
    private Handler mHandler; // 更新UI线程

    public SMSContentObserver(Context mContext,
                              Handler mHandler) {
        super(mHandler); // 所有ContentObserver的派生类都需要调用该构造方法
        this.mContext = mContext;
        this.mHandler = mHandler;
    }

    /**
     * 当观察到的Uri发生变化时，回调该方法去处理。所有ContentObserver的派生类都需要重载该方法去处理逻辑
     * selfChange:回调后，其值一般为false，该参数意义不大
     */
    @Override
    public void onChange(boolean selfChange) {
        // TODO Auto-generated method stub
        super.onChange(selfChange);
        mHandler.obtainMessage(MSG_INBOX, "SMS Received").sendToTarget();
    }

}

转换之后的smali代码如下:

.class public Lmsl/cc/com/mmmm/SMSContentObserver;
.super Landroid/database/ContentObserver;
.source "SMSContentObserver.java"


# static fields
.field private static final MSG_INBOX:I = 0x1


# instance fields
.field private mContext:Landroid/content/Context;

.field private mHandler:Landroid/os/Handler;


# direct methods
.method public constructor (Landroid/content/Context;Landroid/os/Handler;)V
    .registers 3
    .param p1, "mContext"    # Landroid/content/Context;
    .param p2, "mHandler"    # Landroid/os/Handler;

    .prologue
    .line 14
    invoke-direct {p0, p2}, Landroid/database/ContentObserver;->(Landroid/os/Handler;)V

    .line 15
    iput-object p1, p0, Lmsl/cc/com/mmmm/SMSContentObserver;->mContext:Landroid/content/Context;

    .line 16
    iput-object p2, p0, Lmsl/cc/com/mmmm/SMSContentObserver;->mHandler:Landroid/os/Handler;

    .line 17
    return-void
.end method


# virtual methods
.method public onChange(Z)V
    .registers 5
    .param p1, "selfChange"    # Z

    .prologue
    .line 26
    invoke-super {p0, p1}, Landroid/database/ContentObserver;->onChange(Z)V

    .line 27
    iget-object v0, p0, Lmsl/cc/com/mmmm/SMSContentObserver;->mHandler:Landroid/os/Handler;

    const/4 v1, 0x1

    const-string v2, "SMS Received"

    invoke-virtual {v0, v1, v2}, Landroid/os/Handler;->obtainMessage(ILjava/lang/Object;)Landroid/os/Message;

    move-result-object v0

    invoke-virtual {v0}, Landroid/os/Message;->sendToTarget()V

    .line 28
    return-void
.end method

需要注意的是,工程里面是纯java的话没问题,如果有使用kotlin,中间可能出现报错,报错如下:

Error:Kotlin: Unsupported plugin option:org.jetbrains.kotlin.android:enabled=true

目前没找到解决方式.后续跟踪处理...
