appium支持android7.0

运行时报错 Failure [INSTALL_FAILED_ALREADY_EXISTS: Attempt to re-install io.appium.settings without first uninstalling.]

 selenium.common.exceptions.SessionNotCreatedException: Message: A new session could not be created. (Original error: Command failed: C:\WINDOWS\system32\cmd.exe /s /c ""D:\Program Files\android-sdk-windows\platform-tools\adb.exe" -s 893dac07 shell "ps 'uiautomator'""

原因分析：appium的uiautomator版本与androidV7.0不适配。

预置条件：手机端已经安装完Appium Settings 和 Unlock两个应用

解决步骤：1.修改源码文件-注释安装appiumSettings和unlock的两行代码

位置：\Program Files (x86)\Appium\node_modules\appium\lib\devices\android\android.js

//this.initUnicode.bind(this),
//this.pushSettingsApp.bind(this),
//this.pushUnlock.bind(this),

 //this.unlock.bind(this),

 

2.在代码

ADB.prototype.shell = function (cmd, cb) {
if (cmd.indexOf('"') === -1) {
cmd = '"' + cmd + '"';
}
var execCmd = 'shell ' + cmd;
this.exec(execCmd, cb);
};

下插入

ADB.prototype.shell_grep = function (cmd, grep, cb) {
    if (cmd.indexOf('"') === -1) {
        cmd = '"' + cmd + '"';
    }
    var execCmd = 'shell ' + cmd + '| grep ' + grep;
    this.exec(execCmd, cb);
};

 

 

 3.修改源码文件如下：

           a.打开  \Program Files (x86)\Appium\node_modules\appium\node_modules\appium-adb\lib\adb.js

           b.在adb.js的1035行找到

     this.shell("ps '" + name + "'", function (err, stdout) {

     if (err) return cb(err);

     替换成

     this.shell_grep("ps", name, function (err, stdout) {

     if (err) {

     logger.debug("No matching processes found");

     return cb(null, []);

    }

 

 

         3.修改代码，之后重启appium

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);
  this.shell_grep("ps", name, function (err, stdout) {
    if (err) {
        logger.debug("No matching processes found");
        return cb(null, []);
    }
    //stdout = stdout.trim();
    //var procs = [];
    //var outlines = stdout.split("\n");
    //_.each(outlines, function (outline) {
      //if (outline.indexOf(name) !== -1) {
        //procs.push(outline);
      //}
    //});
    //if (procs.length < 1) {
      //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);
  });
};
