appium1.4.6， Android7.0真机测试遇到的问题。

---恢复内容开始---

1.反复提示could not install io.appium.settings 和io.appium.unlocked这个两个apk.  这两个安装过一次就不用重复安装了，安装目录在

D:\Program Files (x86)\Appium\node_modules\appium\build\settings_apk\settings_apk-debug.apk

D:\Program Files (x86)\Appium\node_modules\appium\build\unlock_apk\unlock_apk-debug.apk

安装过后在appium里面设置为不用每次都重装这两个apk，不仅浪费时间还会生成弹窗，特别烦，屏蔽方法，注释掉一些内容，如下：

Appium\node_modules\appium\lib\devices\android\android.jasync.series([

 this.initJavaVersion.bind(this), this.initAdb.bind(this), this.packageAndLaunchActivityFromManifest.bind(this), this.initUiautomator.bind(this), this.prepareDevice.bind(this), this.checkApiLevel.bind(this), this.pushStrings.bind(this), this.processFromManifest.bind(this), this.uninstallApp.bind(this), this.installAppForTest.bind(this), this.forwardPort.bind(this), //this.pushAppium.bind(this), this.initUnicode.bind(this), // DO NOT push settings app and unlock app //this.pushSettingsApp.bind(this), //this.pushUnlock.bind(this), function (cb) {this.uiautomator.start(cb);}.bind(this), this.wakeUp.bind(this), this.unlock.bind(this), this.getDataDir.bind(this), this.setupCompressedLayoutHierarchy.bind(this), this.startAppUnderTest.bind(this), this.initAutoWebview.bind(this), this.setActualCapabilities.bind(this) ], function (err) {
2取消重新安装IME.APK

Appium\node_modules\appium\lib\devices\android\android-common.js

androidCommon.pushUnicodeIME = function (cb) { cb() /* logger.debug("Pushing unicode ime to device..."); var imePath = path.resolve(__dirname, "..", "..", "..", "build", "unicode_ime_apk", "UnicodeIME-debug.apk"); fs.stat(imePath, function (err) { if (err) { cb(new Error("Could not find Unicode IME apk; please run " + "'reset.sh --android' to build it.")); } else { this.adb.install(imePath, false, cb); } }.bind(this)); */ };
3.报错shell "ps 'uiautomator'"   bad pid uiautomator
查看大多数资料说的是做如下更改：
修改appium中adb.js文件，在代码var outlines = stdout.split(“\n”);后加outlines.shift();
目录：C:\Program Files\Appium\node_modules\appium\node_modules\appium-adb\lib
如下：

3.报错shell "ps 'uiautomator'"   bad pid uiautomator
查看大多数资料说的是做如下更改：
修改appium中adb.js文件，在代码var outlines = stdout.split(“\n”);后加outlines.shift();
目录：C:\Program Files\Appium\node_modules\appium\node_modules\appium-adb\lib
如下：

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(); //bad pid 'uiautomator'  添加这一行

但我用这种方法仍然不行，后面在网上找到这种更改方式

1、找到appium的安装目录下的adb.js文件，目录为：Appium\node_modules\appium\node_modules\appium-adb\lib 
2、打开adb.js，找到如下代码：

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

在这段代码下面加入这段代码：

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

再找到如下代码：

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();
    _.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);
  });
};

把这段代码注释掉，用如下代码代替：

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);
  });
};

3、重启appium

问题解决。
