无法通过Android code来执行的SendEvent shell命令 [英] Unable to execute sendevent shell command through the android code

问题描述

我曾尝试以下code段执行批处理命令，为的SendEvent点击模拟器的坐标44129。但它不显示任何结果。但是，如果我给同批命令外壳及时它能够点击提到成功地协调

的String [] = cmmandemulatorarr {/系统/斌/的SendEvent的/ dev /输入/ EVENT0 3 0 44
                /系统/斌/的SendEvent的/ dev /输入/ EVENT0 3 1 129
                /系统/斌/的SendEvent的/ dev /输入/ EVENT0 1 330 1
                /系统/斌/的SendEvent的/ dev /输入/ EVENT0 0 0 0
                /系统/斌/的SendEvent的/ dev /输入/ EVENT0 1 330 0
                /系统/斌/的SendEvent的/ dev /输入/ EVENT0 0 0 0};

 的for（int i = 0; I＆LT; cmmandemulatorarr.length;我++）{         工艺过程=
         调用Runtime.getRuntime（）EXEC（cmmandemulatorarr [I]）。
         读者的BufferedReader =新的BufferedReader（
         新的InputStreamReader（process.getInputStream（）））;
         INT读;
         的char []缓冲区=新的char [4096];
         StringBuffer的输出=新的StringBuffer（）;
         而（（读取= reader.read（缓冲液））大于0）{
         output.append（缓冲，0，读）;
         }
         reader.close（）;
         }    }赶上（IOException异常五）{        抛出新的RuntimeException（E）;    }
 

时有什么我是缺少在这里或者我必须尝试别的东西来获取点击通过code一些坐标事件。

请注意::在执行code这似乎命令执行成功，我没有得到任何异常在日志中。

但它不显示任何结果。

这是一件好事。

  

但是，如果我给同批命令外壳及时它能够点击提到成功地协调

外壳具有root级别的权限运行。您的SDK应用程序不会，除非你铲除你的设备，并安排执行你的code的方式。

请记住，并非所有的设备将有一个 /系统/斌/的SendEvent 命令，它可以在任何时候被删除。这不是Android SDK的一部分。

  

我要尝试其他的东西来获得点击通过code一些坐标事件。

这是不可能的从Android SDK对于普通设备，为明显的安全理由。

I have tried following code snippet to execute the batch of command for sendevent to click the coordinate 44,129 on the emulator. But it is not showing any result. But if i am giving the same batch of command to the shell prompt it is able to click the mentioned coordinate succesfully.

String[] cmmandemulatorarr = {"/system/bin/sendevent /dev/input/event0 3 0 44", "/system/bin/sendevent /dev/input/event0 3 1 129", "/system/bin/sendevent /dev/input/event0 1 330 1", "/system/bin/sendevent /dev/input/event0 0 0 0", "/system/bin/sendevent /dev/input/event0 1 330 0", "/system/bin/sendevent /dev/input/event0 0 0 0", };

         for (int i = 0; i < cmmandemulatorarr.length; i++) {

         Process process =
         Runtime.getRuntime().exec(cmmandemulatorarr[i]);


         BufferedReader reader = new BufferedReader(
         new InputStreamReader(process.getInputStream()));
         int read;
         char[] buffer = new char[4096];
         StringBuffer output = new StringBuffer();
         while ((read = reader.read(buffer)) > 0) {
         output.append(buffer, 0, read);
         }
         reader.close();
         }

    } catch (IOException e) {

        throw new RuntimeException(e);

    }

Is there is anything i am missing here or i have to try something else to get click event on some coordinate through the code.

Note :: I am not getting any exception in the log while executing the code which seems that command is executed successfully.

But it is not showing any result.

This is a good thing.

But if i am giving the same batch of command to the shell prompt it is able to click the mentioned coordinate succesfully.

The shell runs with root-level privileges. Your SDK application does not, unless you root your device and arrange to execute your code that way.

Bear in mind that not all devices will have a /system/bin/sendevent command and it can be removed at any time. This is not part of the Android SDK.

i have to try something else to get click event on some coordinate through the code.

This is not possible from the Android SDK for ordinary devices, for obvious security reasons.
