在调试主屏幕小部件时,调试器在Android Studio中断开连接

Question

我正在尝试调试我制作的Android主屏幕小部件应用程序.当按下窗口小部件上的按钮时,调试器启动,然后它只是从VM断开连接.没有理由.我使用的是Windows 10.

这就是日志所说的:

Disconnected from the target VM, address: 'localhost:8619', transport: 'socket'

我也拉了traces.txt,但没有发现任何明显的错误信息.也许我不知道该找什么.首次将小部件放在屏幕上时,调试器不会断开连接.官方模拟器和GenyMotion都会发生这种情况.模拟器是Google Nexus 5 5.1.0 API 22.

这些是Gradle构建设置:

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.0"
    defaultConfig {
        applicationId "com.gdbd.geedeebeedee"
        minSdkVersion 15
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    } }

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    compile group: 'com.google.code.gson', name: 'gson', version: '2.3.1'
    compile 'com.android.support:appcompat-v7:25.0.0'

    compile 'org.roboguice:roboguice:3.+'
    provided 'org.roboguice:roboblender:3.+'

    testCompile 'junit:junit:4.12' }

有谁知道发生了什么以及为什么我无法调试？谢谢.

编辑5 断点始终位于AppWidget的onReceive()方法中.对于像android.appwidget.action.APPWIDGET_ENABLED这样的其他意图,在调试器停止之前需要更多,但我的应用程序仍然死亡

Answer 1

我进入了模拟设备的设置 - >开发者选项并启用了"显示所有ANR",现在出现警告"您的应用程序没有响应",我可以点击"等待",它似乎工作.

Answer 2

这不是停止分离的解决方案。但是您之后可以直接重新连接调试器。您可以使用工具栏中的按钮将调试器附加到正在运行的进程：

我知道这并不理想，但也许足以为您继续调试了。
