Android Studio调试运行失败：进程崩溃致Instrumentation异常

我正在开发一款Android库，升级至Android Studio Flamingo及配套工具最新版本后，通过UI启动调试运行instrumented测试时，无法连接模拟器或真机。构建日志显示测试运行失败，提示**"Instrumentation run failed due to Process crashed"**，但调试器始终未附加，断点无法生效，排查困难。

已尝试的方案：

• 改用androidx runner
• 按照官方文档重新配置测试依赖
• 排除junit依赖仅保留androidx版本
• 清理缓存等常规操作

完整构建日志：

排查方案 #

1. 提取设备Logcat崩溃堆栈 #

构建日志仅提示进程崩溃，无具体原因。启动测试前打开Logcat面板，过滤AndroidRuntime标签，找到崩溃的完整堆栈信息，这是定位问题的核心依据。

2. 移除实验性模拟器快照配置 #

构建日志中出现警告：android.experimental.testOptions.emulatorSnapshots.maxSnapshotsForTestFailures=0为实验性选项，可能与新版本AGP不兼容。在模块build.gradle中移除该配置，或恢复为默认值。

3. 确认测试APK签名配置 #

确保debugAndroidTest的签名配置正确，新版本AGP可能自动生成签名，但自定义签名规则可能导致测试APK无法正常运行。在build.gradle中明确指定测试签名：

android {
    signingConfigs {
        debug {
            // 你的debug签名配置
        }
    }
    buildTypes {
        debug {
            signingConfig signingConfigs.debug
        }
    }
    testBuildType "debug"
}

4. 降级AGP至稳定版本 #

若Flamingo自带的AGP 8.0+存在兼容性问题，尝试降级到AGP 7.4.x稳定版，验证是否为新版本AGP的bug。修改项目根目录build.gradle：

plugins {
    id 'com.android.library' version '7.4.2' apply false
}

5. 排查测试类初始化代码 #

测试进程崩溃可能源于@BeforeClass、@Before方法中的错误，或依赖库初始化失败。尝试注释测试方法，仅保留空测试，逐步恢复代码排查问题点。

6. 手动运行测试并附加调试器 #

若UI启动调试无法附加，通过命令行启动测试后手动绑定调试器：

• 执行命令：./gradlew :mips:connectedDebugAndroidTest --no-build-cache -Ddebug
• 在Android Studio中通过Run -> Attach debugger to Android process选择末尾带.test的测试进程。

7. 检查测试依赖冲突 #

执行./gradlew :mips:dependencies查看测试依赖树，确认androidx.test相关依赖版本一致，排除重复或不兼容的库版本。
