appium Version: 1_4_16
1. Open the file in the directory appium adb.js installation directory: Appium \ node_modules \ appium \ node_modules \ appium-adb \ lib
ADB.prototype.shell = function (cmd, cb) {
if (cmd.indexOf('"') === -1) {
cmd = '"' + cmd + '"';
}
var execCmd = 'shell ' + cmd;
this.exec(execCmd, cb);
};
In this code, the following code was added the following:
ADB.prototype.shell_grep = function (cmd, grep, cb) {
if (cmd.indexOf('"') === -1) {
cmd = '"' + cmd + '"';
}
var execCmd = 'shell ' + cmd + '| grep ' + grep;
this.exec(execCmd, cb);
};
Find again the following code:
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);
});
};
The code is commented above, replaced by the following code:
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);
});
};
2. Restart appium, connect your phone to see the successful operation to solve the problem have been ok
