调试主屏幕小部件时调试器在 Android Studio 中断开连接

Debugger disconnecting in Android Studio when debugging a home screen widget

我正在尝试调试我制作的 Android 主屏幕小部件应用程序。 当按下小部件上的按钮时,调试器启动,然后它就与 VM 断开连接。没有给出任何理由。我正在使用 Windows 10.

日志是这样说的:

我也拉了traces.txt,但是没有发现明显的报错信息。也许我不知道要寻找什么。首次将小部件放置在屏幕上时,调试器不会断开连接。官方 Emulator 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:

    compileSdkVersion 25
    buildToolsVersion "25.0.0"
    defaultConfig {
        applicationId "com.gdbd.geedeebeedee"

        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 断点总是在我的 AppWidget 的 onReceive() 方法中。 对于 android.appwidget.action.APPWIDGET_ENABLED 等其他意图,调试器停止之前需要更多时间,但我的应用程序仍然死机

也许这对你有帮助。请检查以下建议

您选择您的设备,然后在右侧选择您的包名称,您可以在正则表达式旁边看到从下拉列表中选择仅显示所选应用程序

这不是停止分离的解决方案。但是您可以在之后直接重新附加调试器。您可以使用工具栏中的按钮将调试器附加到 运行 个进程:

我知道这不理想,但也许已经够你继续调试了。

您是否尝试过在 Android Studio 上禁用 Instant 运行。可能是在调试时发生冲突。

使用Android工作室的这个插件。 ADB WIFI

连接两个设备 1) PC/Laptop 2) 在同一网络上移动并执行此操作 工具 -> Android -> ADB WIFI -> ADB USB 转 WIFI。

谢谢

我转到模拟设备的设置 -> 开发人员选项并启用 "Show all ANRs",现在出现警告 "Your application is not responding",我可以点击 "WAIT",它似乎有效。

我有类似的问题。结果 break-point 在线上必须执行一些 UI 任务(意图调用其他 activity)。只需将您的 break-point 移动到其他不涉及 UI 处理的地方。我这样解决了我的问题。
