Android(安卓)studio No executable code found 断点不可用

Android studio 设置了断点，但是开始调试后，看到的却是一个带×的断点

Warning: No executable code found at line 482 in class com.xx.xx.

1、所有的断点都是带×的

在module的build.gradle中设置minifyEnabled 为false

buildTypes {    release {        minifyEnabled true        shrinkResources true        proguardFiles getDefaultProguardFile('proguard-android.txt')        signingConfig signingConfigs.release    }    debug {        debuggable true        minifyEnabled false //这是关键的，我的问题就是出在这里        proguardFiles getDefaultProguardFile('proguard-android.txt')        signingConfig signingConfigs.release    }}

如果还想使用代码混淆，还想可以断点调试正常，可是参见这里的smoothumut的回答，博主未验证是否可行

2、若只是个别地方，显示带×的断点

I had similar problems and various attempts has been applied. Below is my usual steps:

If you are using Maven dependencies, go to Maven Projects -> refresh
If that does not work, Try top menu –> Build –> Rebuild Project
If that still doesn’t work, try top menu –> File –> Invalidate Cache/Restart
If that still doesn’t work, then $CATALINA_BASE/bin/catalina.sh stop, then start

After this, usually it covers 99% of the problems. Otherwise, Probably you will have to examine some other possibilities.

2和3两个步骤可以解决问题，若不行再尝试全部步骤

3、真机调试，第一个断点正常，第2个断点显示带×
