1、APK反编译。

2、在AndroidManifest中找到主Activity：com.mm.cm.sbz.ApplicationDemo

3、打开ApplicationDemo.class，可以很容易发现三个关于付费的成员变量：

4、再往下看，可以看到付费失败和 付费成功的成员方法：

在startGame1()方法中可以看到该应用的APPID和APPKEY：

5、我们很容易想到将付费失败方法的内容替换成付费成功的内容，那么这样无论购买成功与否，最终都会执行成功时的动作，因此我们将付费失败的smali代码替换成成功的代码。
修改前的代码：
[AppleScript] 纯文本查看 复制代码
.method private billingFailed(I)V
    .locals 1
    .parameter "sbillingIndex"

    .prologue
    .line 224
    const/4 v0, 0x0

    invoke-static {p1, v0}, Lcom/mm/cm/sbz/ApplicationDemo;->nativeBillingSuccess(II)V

    .line 225
    return-void
.end method


修改后的代码：
[AppleScript] 纯文本查看 复制代码
.method private billingFailed(I)V
    .locals 2
    .parameter "sbillingIndex"

    .prologue
    .line 229
    const/4 v0, 0x1

    invoke-static {p1, v0}, Lcom/mm/cm/sbz/ApplicationDemo;->nativeBillingSuccess(II)V

    .line 231
    packed-switch p1, :pswitch_data_0

    .line 256
    :goto_0
    return-void

    .line 234
    :pswitch_0
    const-string v0, "30000283477701"

    const-string v1, "6"

    invoke-static {p0, v0, v1}, Lcom/cm/tools/Tool;->startGamePay(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;)V

    goto :goto_0

    .line 237
    :pswitch_1
    const-string v0, "30000283477703"

    const-string v1, "1"

    invoke-static {p0, v0, v1}, Lcom/cm/tools/Tool;->startGamePay(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;)V

    const-string v1, "1"

    invoke-static {p0, v0, v1}, Lcom/cm/tools/Tool;->startGamePay(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;)V

    goto :goto_0

    .line 243

    const-string v1, "1"

    invoke-static {p0, v0, v1}, Lcom/cm/tools/Tool;->startGamePay(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;)V

    goto :goto_0

    .line 246
    :pswitch_4
    const-string v0, "30000283477704"

    const-string v1, "1"

    invoke-static {p0, v0, v1}, Lcom/cm/tools/Tool;->startGamePay(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;)V

    goto :goto_0

    .line 249
    :pswitch_5
    const-string v0, "30000283477706"

    const-string v1, "2"

    invoke-static {p0, v0, v1}, Lcom/cm/tools/Tool;->startGamePay(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;)V

    goto :goto_0

    .line 252
    :pswitch_6
    const-string v0, "30000283477707"

    const-string v1, "2"

    invoke-static {p0, v0, v1}, Lcom/cm/tools/Tool;->startGamePay(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;)V

    goto :goto_0

    .line 231
    :pswitch_data_0
    .packed-switch 0x0
        :pswitch_0
        :pswitch_1
        :pswitch_2
        :pswitch_3
        :pswitch_4
        :pswitch_5
        :pswitch_6
    .end packed-switch
.end method


6、修改保存，重新编译签名，测试发现，当我们点击某个物品购买时，会弹出相应的购买界面，此时我们只要点击返回按钮，购买就成功了！
图4.png

7、到此，已经达到了破解内购的目的，但是不完美，因为会弹出购买界面，我们想要点击购买时，不弹出任何界面就成功购买。继续分析，在  public void addAdvertisement2(int paramInt)方法中发现有“网络连接失败”的字眼，并且有对各个物品购买的监听事件，因此我们在这里面做文章，给它偷天换日。将addAdvertisement2的smali代码替换成付费成功的代码.
