Android studio gradle断点在行中找不到可执行代码 [英] Android studio gradle breakpoint No executable code found at line

问题描述

我正在使用 Android Studio 2.1.3 和 gradle 开发一个 android 应用程序.

问题是简单方法中的断点永远不会命中，虽然必须命中，因为在应用程序调试时满足条件.
首先，我认为问题与此问题的答案中描述的问题有关:

这也不是唯一的情况.碰巧的是，编译器在单步执行时会完全跳转到代码的另一部分，而不是被调试的部分.

这里有什么合理的解释吗?挂起:线程"和所有"都试过了，结果一样.

更新 1:使用 Eclipse 重新创建项目，一切正常.还是很奇怪为什么用Android studio这不行！

解决方案

在使用 Eclipse 重新创建应用程序并观察到正确行为后，我返回 Android Studio 以检查是否有任何我遗漏的选项.

在尝试了 File -> Settings 中的所有选项后，我得出的结论是 Instant Run 是导致我浪费这么多宝贵时间的邪恶.

我不明白它与我的问题有什么关系，但在清除所有复选框后:

我最终得到了一个按照我作为开发人员期望的方式执行的代码:

I am developing an android application using Android Studio 2.1.3 and gradle.

The problem is that the breakpoint in a simple method is never hit, although it must be hit because the condition is met during application debugging.
First, I thought that the problem is related to the issue described in the answer for this question: BuildConfig.DEBUG always false when building library projects with gradle

To test this, I removed library project and integrated all my source code into the main app module. It solved nothing. To be noted that the following is the build.gradle, where minify is set to false for both debug/release:

apply plugin: 'com.android.application'  

android {  
    compileSdkVersion 23  
    buildToolsVersion "23.0.2"  
    defaultConfig {  
        applicationId "com.mycompany.mymobileapp"  
        minSdkVersion 21  
        targetSdkVersion 21  
        versionCode 1  
        versionName "1.0"  
    }  
    buildTypes {  
        release {  
            minifyEnabled false  
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'  
            debuggable true  
            jniDebuggable true  
            renderscriptDebuggable true  
            zipAlignEnabled false  
        }  
        debug {  
            debuggable true  
            minifyEnabled false  
            zipAlignEnabled false  
            jniDebuggable true  
            renderscriptDebuggable true  
        }  
    }  
    productFlavors {  
    }  
}  
  
dependencies {  
    compile fileTree(include: ['*.jar'], dir: 'libs')  
    testCompile 'junit:junit:4.12'  
    testCompile 'org.mockito:mockito-core:2.0.5-beta'  
    testCompile 'com.android.support:support-v4:23.1.1'  
    testCompile 'org.powermock:powermock-api-mockito:1.6.2'  
    testCompile 'org.powermock:powermock-module-junit4-rule-agent:1.6.2'  
    testCompile 'org.powermock:powermock-module-junit4-rule:1.6.2'  
    testCompile 'org.powermock:powermock-module-junit4:1.6.2'  
    compile 'com.android.support:appcompat-v7:23.1.1'  
}

Here is the screenshot with what Android Studio shows to me:

This is also not the only case. It happens that the compiler, while Stepping over, jumps to completely another part of the code than the one being debugged.

Is there any reasonable explanation here? Suspend: "thread" and "all" tried, same result.

UPDATE 1: Re-created the project using Eclipse, and everything works fine. It is still amazing why using Android studio this does not work!

解决方案

After re-creating the application using Eclipse and observing the correct behavior, I returned to Android Studio in order to check if there is any option that I missed.

After trying all the options from File -> Settings that I could, I made the conclusion that Instant Run is the evil that caused me to waste so much precious time.

I don't understand how it is related with my problem, but after clearing all check-boxes:

I ended up with a code that executes the way I as a developer expect:
