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，调试器将启动，然后它只是与 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:

我也提取了 traces.txt，但没有发现任何明显的错误信息。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 build设置:

android {
    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。

显然该进程终止了。

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 Intent ，在调试器停止之前需要更多时间，但我的应用仍然死机

最佳答案

我转到模拟设备的设置 -> 开发人员选项并启用“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。
