Question

您好，我需要在手机中搜索并列出所有尝试启动Intent（Intent.ACTION_CALL）的应用程序，这些应用程序都支持它。我不知道是否有可能，我检查了Intent.createChooser（）方法的实现，但我并不幸运。

我真正想做的是一个视图，用户可以在该视图中配置要执行的呼叫某人操作的应用程序。这就是为什么我需要搜索用户手机中支持Intent.ACTION_CALL的所有应用程序以在列表中显示它们的原因。在用户选择了所需的应用程序之后，我将管理用户何时拨打电话，启动他选择的应用程序。

谢谢

尝试使用这段代码

pd = [ #This is the visual of the pyramid

[                 1                    ], #[0][0]  row and total col# ex [2][1] = 5
[              2,    3                 ], #[1][1]
[            4,   5,    6,             ], #[2][2]
[         7,   8,    9,   10,          ], #[3][3]
[      11,  12,   13,  14,   15,       ], #[4][4]
[    16,  17,   18,  19,  20,    21,   ], #[5][5]

]

x = 0 # represents left and right direction in pd -- adding goes right, subtracting goes left
y = 5 # represents up and down direction in pd -- adding goes down, subtracting goes up

lower_bound = 1 #used as lower bound in dice selection

move_counter = 0 #used to count the total number of moves made in game

# ---- loop end ----

这将检查是否有可用的应用程序来完成此操作。
