Appium 版本不支持，需要 UIAutomator2.0

appium 版本 1.4.16，android7.0，使用的手机是华为 Mate9,执行时，报错

有知道是什么原因吗？

按照这个方法解决就行，

解决 Android 7.0 系统的手机无法执行 appium 脚本的问题，改问题的具体解决方法如下：
1、 找到 appium 的安装目录下的 adb.js 文件，windows 版本的目录如下：Appium\node_modules\appium\node_modules\appium-adb\lib
2、 打开 adb.js，手动修改该文件下的内容：
ADB.prototype.getPIDsByName = function (name, cb) {
logger.debug("Getting all processes with '" + name + "'");
this.shell("ps '" + name + "'", function (err, stdout) {
if (err) return cb(err);
stdout = stdout.trim();
var procs = [];
var outlines = stdout.split("\n");
outlines.shift(); //在该处添加此行代码
3、重启 appium

楼上方法太给力了，怎么想到这方法的啊，原理是什么

原因:
adb.js 中 1035 行 this.shell("ps '" + name + "'", function (err, stdout) {
对应执行的指令是 ps 'uiautomator', Android7 不支持这个指令格式，所以执行结果是 bad pid 'uiautomator'
目前 Appium 未对此进行处理,所以需要修改此指令的执行方式

这是哪里出错了，看不懂

软件已经安装了，删了再试试

改了之后还是有这个报错

最后怎么弄好的啊？

你是在胡说八道！

我查看 adb.js 连这个方法都没找到 不晓得是怎么回事呢

一楼方法没解决，我用另一个方法解决了：
Go to adb.js in the path 'node_modules//appium/node_modules/appium-adb/lib/adb.js'
**Find the below*
ADB.prototype.shell = function (cmd, cb) {
if (cmd.indexOf('"') === -1) {
cmd = '"' + cmd + '"';
}
var execCmd = 'shell ' + cmd;
this.exec(execCmd, cb);
};
Append the below
ADB.prototype.shell_grep = function (cmd, grep, cb) {
if (cmd.indexOf('"') === -1) {
cmd = '"' + cmd + '"';
}
var execCmd = 'shell ' + cmd + '| grep ' + grep;
this.exec(execCmd, cb);
};
2 Find the 'ADB.prototype.getPIDsByName ' and replace the whole section

ADB.prototype.getPIDsByName = function (name, cb) {
logger.debug("Getting all processes with '" + name + "'");
this.shell_grep("ps", name, function (err, stdout) {
if (err) {
logger.debug("No matching processes found");
return cb(null, []);
}
var pids = [];
_.each(procs, function (proc) {
var match = /[^\t ]+[\t ]+([0-9]+)/.exec(proc);
if (match) {
pids.push(parseInt(match[1], 10));
}
});
if (pids.length !== procs.length) {
var msg = "Could not extract PIDs from ps output. PIDS: " +
JSON.stringify(pids) + ", Procs: " + JSON.stringify(procs);
return cb(new Error(msg));
}
cb(null, pids);
});
};
