Android极简启动器开机启动RealDash异常：设备持续重启排查

问题描述

我想开发一款无图形界面的Android极简启动器，实现手机开机后立即启动RealDash应用。但将其设置为默认启动器后，设备持续重启，RealDash并未启动。以下是我的代码及Logcat日志，请问是否需要指定应用完整路径，或是我遗漏了其他配置？

问题分析与解决方法

核心崩溃原因：BootReceiver类缺失
Logcat明确报错ClassNotFoundException: com.example.customlauncher.BootReceiver，你在Manifest中注册了该广播接收器，但未创建对应的BootReceiver.kt文件，导致应用启动即崩溃，进而触发系统重复重启启动器。
- 解决：直接删除Manifest中<receiver>相关配置即可——作为默认启动器，系统会自动在开机后启动它的MainActivity，完全不需要监听BOOT_COMPLETED广播。

循环重启问题修复
当你的启动器作为默认HOME应用时，若MainActivity直接finish但未成功启动目标应用，系统会判定启动器崩溃，反复尝试重启它，形成循环。

验证目标应用包名：通过adb shell pm list packages | grep RealDash命令确认RealDash的真实包名是否为com.napko.RealDash，避免包名错误导致启动失败。

添加错误兜底逻辑：如果获取不到RealDash的启动Intent，不要直接finish，显示一个简单的错误提示界面，阻止系统重复启动：

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    val launchIntent = packageManager.getLaunchIntentForPackage("com.napko.RealDash")
    if (launchIntent != null) {
        startActivity(launchIntent)
        finish()
    } else {
        // 显示错误提示，避免系统循环重启
        setContentView(android.widget.TextView(this).apply {
            text = "RealDash未安装或包名错误"
            textSize = 20f
            gravity = android.view.Gravity.CENTER
        })
    }
}

无图形界面优化
若要实现完全无界面启动，可给MainActivity设置透明主题，避免启动时闪屏：
在Manifest的<activity>标签中添加：
```
android:theme="@android:style/Theme.Translucent.NoTitleBar"
```
冗余配置清理
删除Manifest中的RECEIVE_BOOT_COMPLETED权限，因为默认启动器无需该权限即可被系统自动启动。
