Question

我正在尝试使用Samsung Infuse 4g手机调试Android应用程序。在手机上启用了USB调试。我在清单中添加了debuggable = true; Logcat称调试器已经解决（1325）。但是当我运行代码时，它不会在我的断点处停止，并且我在变量窗口中看不到任何变量。任何想法在这里出了什么问题？这是logcat输出：

04-03 00:55:47.210: I/System.out(8726): Sending WAIT chunk
04-03 00:55:47.218: I/dalvikvm(8726): Debugger is active

04-03 00:55:49.249: I/System.out(8726): debugger has settled (1325)

我唯一一次看到调试器正在做某事是我故意使程序崩溃的时候。然后我看到了Double.ParseDouble（String）的异常，但是我错过了它的源代码...我甚至尝试过模拟器，我遇到了同样的问题，没有调试，直到我崩溃程序。

package com.example.calculator;



public  class Math {
double mathValue;
double totalValue;
int lastOperator;

public double getTotalValue(){
    if (this.totalValue == 0)
        return this.mathValue;
    else
    return this.totalValue;
}

public void add(){

}

public void setOperater(String nextOperater){
    if (nextOperater == "+")
        this.lastOperator = 1;

    if (nextOperater == "-")
        this.lastOperator = 2;

    if (nextOperater == "*")
        this.lastOperator = 3;

    if (nextOperater == "/")
        this.lastOperator = 4;

    if (nextOperater == "")
        this.mathValue = 0;



}

public void doMath(double inValue){
    this.mathValue = inValue;
    switch (lastOperator){
    case 1 : Add();
            break;
    case 2 : Subtract();
            break;
    case 3 : Multiply();
            break;
    case 4: Divide();
            break;

    }

}

public void Add(){
    System.out.println("The line before my breakpoint");
    totalValue += mathValue; <---- break point
    System.out.println("The line after my breakpoint");
}

public void Subtract(){

    totalValue -= mathValue;
}

public void Multiply(){

    totalValue *= mathValue;
}

public void Divide(){
    if (mathValue == 0)
        totalValue = 0;
    else
        totalValue /= mathValue;

}

}

Answer 1

您需要以调试模式运行应用

Debug Mode

Answer 2

确保在调试控件中未启用“跳过所有断点”。

Answer 3

在AndroidManifest.xml中将您的应用程序声明为“debuggable”。

<application
    android:debuggable="true"
    ... >
    ...
</application>
