通过ddmlib杀死某个android进程的方法

首先获取ps指令的打印信息：

private static String getPsPrint(IDevice device) {
OutputStream os = new ByteArrayOutputStream();

try {
device.executeShellCommand("ps",
new OutputStreamShellOutputReceiver(os));
os.flush();
return os.toString();
} catch (TimeoutException e) {
e.printStackTrace();
} catch (AdbCommandRejectedException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (ShellCommandUnresponsiveException e) {
e.printStackTrace();
}

return "";
}

其中OutputStreamShellOutputReceiver类：

public class OutputStreamShellOutputReceiver implements IShellOutputReceiver {

OutputStream os;

public OutputStreamShellOutputReceiver(OutputStream os) {
this.os = os;
}

public boolean isCancelled() {
return false;
}

public void flush() {
}

public void addOutput(byte[] buf, int off, int len) {
try {
os.write(buf,off,len);
} catch(IOException ex) {
throw new RuntimeException(ex);
}
}

}

获得ps的打印信息之后，需要根据进程名分析出pid：

public static String parsePid(IDevice device, String exeName) {

String content = getPsPrint(device);
String[] pidInfos = content.split("\n");
for (String info : pidInfos) {
if (info != null) {
// shell 18867 18856 852 300 c022c0bc afe0cdec S ./gsnap
if (info.contains(exeName)) {
String[] fragments = info.split(" ");
int idx = 0;
for (String str : fragments) {
if ((str != null) && (!str.trim().equals(""))) {
idx++;
}

if (idx == 2) {
return str;
}
}
}
}
}

return "";
}

最后，根据得到的pid，杀掉此android进程：

public static void killProcess(IDevice device, String pid) {
// 旧的手机，缺乏grep和awk程序！
//String killCmd = "kill -9 `ps | grep \"gsnap\" | grep -v \"grep\" | awk '{print $2}'`";
String killCmd = "kill -9 " + pid;

try {
device.executeShellCommand(killCmd,
new OutputStreamShellOutputReceiver(System.out));
} catch (TimeoutException e) {
e.printStackTrace();
} catch (AdbCommandRejectedException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (ShellCommandUnresponsiveException e) {
e.printStackTrace();
}
}

之所以会这么复杂，是因为这个：

// 旧的手机，缺乏grep和awk程序！

//String killCmd = "kill -9 `ps | grep \"gsnap\" | grep -v \"grep\" | awk '{print $2}'`";
