解決方法1：
在真機(jī)上 手動卸載 ?AppimSetting ?和 ?Unlock 兩個應(yīng)用
解決方法2（注釋安裝應(yīng)用的代碼）：
在window 系統(tǒng)下，找到appium 安裝目錄
C:\Program Files (x86)\Appium\node_modules\appium\lib\devices\android
找到Android.js 文件，注釋下述的三行代碼即可：（顏色為紅色的代碼行）
如果手機(jī)上未安裝這兩個應(yīng)用：
解決方法3：
1. adb.js 中1035 行this.shell("ps '" + name + "'", function (err, stdout) {
對應(yīng)執(zhí)行的指令是ps 'uiautomator', Android7不支持這個指令格式塑悼，所以執(zhí)行結(jié)果是bad pid'uiautomator'
目前Appium未對此進(jìn)行處理,所以需要修改此指令的執(zhí)行方式
即將
this.shell("ps '" + name + "'", function (err, stdout) {
if (err) return cb(err);
替換成
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函數(shù)：
ADB.prototype.shell_grep = function (cmd, grep, cb) {
if (cmd.indexOf('"') === -1) {
cmd = '"' + cmd + '"';
}
var execCmd = 'shell ' + cmd + '| grep ' + grep;
this.exec(execCmd, cb);
};
