Android studio 設定了斷點，但是開始除錯後，看到的卻是一個帶×的斷點

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

1、所有的斷點都是帶×的

參考：http://stackoverflow.com/questions/21743442/cant-reach-some-lines-debugging-android-app

在module的build.gradle中設定minifyEnabled 為false

buildTypes {    release {        minifyEnabled true        shrinkResources true        proguardFiles getDefaultProguardFile('proguard-android.txt'
 
)        signingConfig signingConfigs.release    }    debug {        debuggable true        minifyEnabled false //這是關鍵的，我的問題就是出在這裡        proguardFiles getDefaultProguardFile('proguard-android.txt')        signingConfig signingConfigs.release    }}

如果還想使用程式碼混淆，還想可以斷點除錯正常，可是參見這裡的smoothumut的回答，博主未驗證是否可行

2、若只是個別地方，顯示帶×的斷點

參考：http://stackoverflow.com/questions/11591662/cannot-set-java-breakpoint-in-intellij-idea

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

1. If you are using Maven dependencies, go to Maven Projects -> refresh
2. If that does not work, Try top menu –> Build –> Rebuild Project
3. If that still doesn’t work, try top menu –> File –> Invalidate Cache/Restart
4. 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3兩個步驟可以解決問題，若不行再嘗試全部步驟

3、真機除錯，第一個斷點正常，第2個斷點顯示帶×
