Framework

这里记录了 Framework 定制的常用方法

一键截屏.kt

fun screenCapture(context: Context) {
    val screenPath =
        "${context.getExternalFilesDir(Environment.DIRECTORY_PICTURES)?.absolutePath}/ScreenCaps/"
    val path = "$screenPath/ScreenCap_${System.currentTimeMillis()}.png"
    val file = File(screenPath)
    if (!file.exists()) {
        file.mkdir()
    }
    Runtime.getRuntime().exec("screencap -p $path")
}

清理最近任务列表.kt

//清空全部
fun clearAll(){
    // 9.0 后删除了 ActivityManager 的 removeTask() 方法
    //import android.app.ActivityTaskManager.getService
    //清空最近任务
    getService().removeAllVisibleRecentTasks()  
}

//根据包名清理
fun clearPackage(packageName : String){
    val manager = getSystemService(Context.ACTIVITY_SERVICE) as ActivityManager
    val recentTasks = manager.getRecentTasks(Int.MAX_VALUE, ActivityManager.RECENT_WITH_EXCLUDED)
    recentTasks.forEach { task ->
        if(packageName == task.baseIntent.component?.packageName){
            getService().removeTask(task.taskId)
            return
        }
    }
}
