appium===报错Failure [INSTALL_FAILED_ALREADY_EXISTS: Attempt to re-install io.appium.settings without first uninstalling.的解决办法

要解决的问题:appium在androidV7.0系统上运行时报错 Failure [INSTALL_FAILED_ALREADY_EXISTS: Attempt to re-install io.appium.settings without first uninstalling.]

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

文件路径: C:\Program Files (x86)\Appium\node_modules\appium\lib\devices\android\android.js

2.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, []);

    }

并增加上面用到的shell_grep函数:

    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.重启appium
