你可以使用

ActivityManager.getRunningServices(int maxNum)：

PackageManager pm = context.getPackageManager();

ActivityManager am = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);

List runningServices = am.getRunningServices(Integer.MAX_VALUE);

for (ActivityManager.RunningServiceInfo service : runningServices) {

String appName;

try {

appName = pm.getApplicationInfo(service.process, 0).loadLabel(pm).toString();

} catch (PackageManager.NameNotFoundException e) {

appName = null;

}

int uid = service.uid;

long ulBytes = TrafficStats.getUidTxBytes(uid);

long dlBytes = TrafficStats.getUidRxBytes(uid);

}

文檔說明這不適用于生產(chǎn).我也沒有做太多測試.如果不符合您的要求,請發(fā)表評論.我能想到的另一件事就是在shell中解析運行ps的輸出.

UPDATE

在shell中解析ps的輸出,我們可以獲得當前正在運行的應用程序.例：

PackageManager pm = context.getPackageManager();

// Get the output of running "ps" in a shell.

// This uses libsuperuser: https://github.com/Chainfire/libsuperuser

// To add this to your project: compile 'eu.chainfire:libsuperuser:1.0.0.+'

List stdout = Shell.SH.run("ps");

List packages = new ArrayList<>();

for (String line : stdout) {

// Get the process-name. It is the last column.

String[] arr = line.split("\\s+");

String processName = arr[arr.length - 1].split(":")[0];

packages.add(processName);

}

// Get a list of all installed apps on the device.

List apps = pm.getInstalledApplications(0);

// Remove apps which are not running.

for (Iterator it = apps.iterator(); it.hasNext(); ) {

if (!packages.contains(it.next().packageName)) {

it.remove();

}

}

for (ApplicationInfo app : apps) {

String appName = app.loadLabel(pm).toString();

int uid = app.uid;

long ulBytes = TrafficStats.getUidTxBytes(uid);

long dlBytes = TrafficStats.getUidRxBytes(uid);

/* do your stuff */

}
