如何调试android应用程序的smali代码？

1.调试smali中的日志

在smali中调试日志.比如在方法test()里面想要打印"Inside Test()"调试日志.在smali方法的开头添加以下说明:

sget-object v0, Ljava/lang/System;->out:Ljava/io/PrintStream;

const-string v1, "Inside Test()"

invoke-virtual {v0, v1}, Ljava/io/PrintStream;->println(Ljava/lang/String;)V

注 -在此处使用寄存器v0,v1时需要小心.在代码执行流程中,您必须检查您是否正在使用流程中稍后使用的寄存器之一.或者你可能会得到例外.

2. StackTrace

这是一个打印方法的stacktrace的smali代码

Java代码

public static void printStackTraces() {
    StackTraceElement[] stackTraceElements = Thread.currentThread().getStackTrace(); 
    for (StackTraceElement element : stackTraceElements) {
        System.out.println("Class name :: " + element.getClassName() + "  || method name :: " + element.getMethodName());
    }
}

等效的smali代码是

.method public static printStackTraces()V
    .locals 7

    .prologue
    .line 74
    invoke-static {}, Ljava/lang/Thread;->currentThread()Ljava/lang/Thread;

    move-result-object v2

    invoke-virtual {v2}, Ljava/lang/Thread;->getStackTrace()[Ljava/lang/StackTraceElement;

    move-result-object v1

    .line 75
    .local v1, stackTraceElements:[Ljava/lang/StackTraceElement;
    array-length v3, v1

    const/4 v2, 0x0

    :goto_0
    if-lt v2, v3, :cond_0

    .line 78
    return-void

    .line 75
    :cond_0
    aget-object v0, v1, v2

    .line 76
    .local v0, element:Ljava/lang/StackTraceElement;
    sget-object v4, Ljava/lang/System;->out:Ljava/io/PrintStream;

    new-instance v5, Ljava/lang/StringBuilder;

    const-string v6, "Class name :: " 

    invoke-direct {v5, v6}, Ljava/lang/StringBuilder;-><init>(Ljava/lang/String;)V

    invoke-virtual {v0}, Ljava/lang/StackTraceElement;->getClassName()Ljava/lang/String;

    move-result-object v6

    invoke-virtual {v5, v6}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;

    move-result-object v5

    const-string v6, "  || method name :: " 

    invoke-virtual {v5, v6}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;

    move-result-object v5

    invoke-virtual {v0}, Ljava/lang/StackTraceElement;->getMethodName()Ljava/lang/String;

    move-result-object v6

    invoke-virtual {v5, v6}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;

    move-result-object v5

    invoke-virtual {v5}, Ljava/lang/StringBuilder;->toString()Ljava/lang/String;

    move-result-object v5

    invoke-virtual {v4, v5}, Ljava/io/PrintStream;->println(Ljava/lang/String;)V

    .line 75
    add-int/lit8 v2, v2, 0x1

    goto :goto_0
.end method

将此方法添加到任何smali文件中.并打电话给

(假设您将上面的smali代码添加到com.example.pakagename.ClassName中)

invoke-static {}, Lcom/example/packagename/ClassName;->printStackTraces()V

希望这可以帮助 .....

现在，您可以为Android Studio或Intellij IDEA- Smalidea使用出色的插件。此外，我在博客文章中介绍了安装过程和调试。
