java - 如何使用 JDB 在嵌套类中正确设置断点？

Question

package com.android.internal.telephony.dataconnection;

public abstract class DcTrackerBase extends Handler {
    protected BroadcastReceiver mIntentReceiver = new BroadcastReceiver ()
    {
        @Override
        public void onReceive(Context context, Intent intent)
        {
            String action = intent.getAction();
            if (DBG) log("onReceive: action=" + action);
[...]

在上面的代码中，使用jdb，我想在onReceive 方法上设置一个断点。我使用了以下命令:

> stop in com.android.internal.telephony.dataconnection.DcTrackerBase$mIntentReceiver.onReceive

我从 jdb 得到这个:

> Deferring breakpoint com.android.internal.telephony.dataconnection.DcTrackerBase$mIntentReceiver.onReceive.
It will be set after the class is loaded.

我知道该类已经加载，所以我想 jdb 没有找到我想要的方法。那我应该如何设置我的断点呢？

Answer 1

争论的方法名称是错误的。

在 JDB 中，发出此命令来检查 DcTrackerBase 类:

> class com.android.internal.telephony.dataconnection.DcTrackerBase
Class: com.android.internal.telephony.dataconnection.DcTrackerBase
extends: android.os.Handler
subclass: com.android.internal.telephony.dataconnection.DcTracker
nested: com.android.internal.telephony.dataconnection.DcTrackerBase$1

正如我们所见，嵌套类 DcTrackerBase$1 可能是我们的 BroadcastReceiver 类。要验证，请发出以下命令:

> class com.android.internal.telephony.dataconnection.DcTrackerBase$1
Class: com.android.internal.telephony.dataconnection.DcTrackerBase$1
extends: android.content.BroadcastReceiver

就是这样!要正确设置断点，我们键入:

> stop in com.android.internal.telephony.dataconnection.DcTrackerBase$1.onReceive
Set breakpoint com.android.internal.telephony.dataconnection.DcTrackerBase$1.onReceive
