Is there a way to get current process name in Android

Solution 1:

Full code is

    String currentProcName = "";
    int pid = android.os.Process.myPid();
    ActivityManager manager = (ActivityManager) this.getSystemService(Context.ACTIVITY_SERVICE);
    for (RunningAppProcessInfo processInfo : manager.getRunningAppProcesses())
    {
        if (processInfo.pid == pid)
        {
            currentProcName = processInfo.processName;
            return;
        }
    }

Solution 2:

The ActivityManager solution contains a sneaky bug, particularly if you check your own process name from your Application object. Sometimes, the list returned from getRunningAppProcesses simply doesn't contain your own process, raising a peculiar existential issue.

The way I solve this is

    BufferedReader cmdlineReader = null;
    try {
        cmdlineReader = new BufferedReader(new InputStreamReader(
            new FileInputStream(
                "/proc/" + android.os.Process.myPid() + "/cmdline"),
            "iso-8859-1"));
        int c;
        StringBuilder processName = new StringBuilder();
        while ((c = cmdlineReader.read()) > 0) {
            processName.append((char) c);
        }
        return processName.toString();
    } finally {
        if (cmdlineReader != null) {
            cmdlineReader.close();
        }
    }

EDIT: Please notice that this solution is much faster than going through the ActivityManager but does not work if the user is running Xposed or similar. In that case you might want to do the ActivityManager solution as a fallback strategy.

Solution 3:

Get it from ActivityThread

In API 28+, you can call Application.getProcessName(), which is just a public wrapper around ActivityThread.currentProcessName().

On older platforms, just call ActivityThread.currentProcessName() directly.

Note that prior to API 18, the method was incorrectly called ActivityThread.currentPackageName() but still in fact returned the process name.

Example code

public static String getProcessName() {
    if (Build.VERSION.SDK_INT >= 28)
        return Application.getProcessName();

    // Using the same technique as Application.getProcessName() for older devices
    // Using reflection since ActivityThread is an internal API

    try {
        @SuppressLint("PrivateApi")
        Class<?> activityThread = Class.forName("android.app.ActivityThread");

        // Before API 18, the method was incorrectly named "currentPackageName", but it still returned the process name
        // See https://github.com/aosp-mirror/platform_frameworks_base/commit/b57a50bd16ce25db441da5c1b63d48721bb90687
        String methodName = Build.VERSION.SDK_INT >= 18 ? "currentProcessName" : "currentPackageName";

        Method getProcessName = activityThread.getDeclaredMethod(methodName);
        return (String) getProcessName.invoke(null);
    } catch (ClassNotFoundException e) {
        throw new RuntimeException(e);
    } catch (NoSuchMethodException e) {
        throw new RuntimeException(e);
    } catch (IllegalAccessException e) {
        throw new RuntimeException(e);
    } catch (InvocationTargetException e) {
        throw new RuntimeException(e);
    }
}
